Household water purifier for the kitchen. Water purification systems in the apartment. Aquaphor Crystal Eco

Domestic osmosis Platinum Wasser Ultra 7 Bio

A seven-stage water purification system with a separate faucet and a storage tank, designed to obtain the highest quality drinking water. The main filter element is a semi-permeable membrane that purifies water at the molecular level. The filter is easy to install under the sink. The system is completed with a tank and a double tap for clean water, which allows you to get drinking water from a separate, independent source, both with minerals (for consumption) and clean water (for coffee machines, steam and ice makers, etc.)

Increasingly, people are faced with the problem of poor quality tap water. And if in cities where there is a central water supply, it is still at least somehow cleaned (although not ideally), then in private territories there is none of this. In mountainous areas, with many springs, the situation is better, but in general, water from there often requires high-quality filtration. Nowadays, many different installations for such cleaning have appeared on store shelves. And in this huge assortment of types, firms and models, it is not surprising to get confused. Today we will try to figure out how to choose water filters for a private house and which of the devices is necessary in a given situation.

A water filter for the kitchen is a must these days.

It has long become not a luxury, but a necessity. In addition, now a person with any income can purchase such equipment. After all, manufacturers offer both quite expensive models and budget ones, such as filter jugs, which can be bought for 500-700 rubles. Of course, more expensive filters connected to the water supply system provide better cleaning, but there are nuances here too. After all, if you choose the wrong cartridges, then the quality of the water will not change.

Important information! Before purchasing a treatment plant, it is necessary to call specialists for the production of an examination of water. Only she can determine which elements in the water are overabundant. It is on the basis of the results of such an examination that a conclusion is made about the need to purchase filter elements with certain properties.

Household filters for water purification can be placed under the sink or on the wall, located directly on the inlet pipe to the living room, or even stand separately, without mounting to the mains. It all depends on the quality of the necessary filtration and the financial capabilities of the person. It should be understood that the purification of drinking water is very important. The health of everyone living in the house depends on this. This means that the need for filtering should never be underestimated.

What is the reason for the need for a water purification system in private homes

The main problem of the private sector is that wells, like some wells, make it possible to draw groundwater. And human waste can freely get into them. For example, not far from a well or well there is a small garbage dump. It rains and everything that is washed out of the waste ends up in the soil. Water with harmful impurities comes through the soil to the first solid layer of the earth and rushes to the well or well. Of course, the soil itself filters it a little, but such natural cleansing does not last forever. Over time, the soil itself, on the way to the water going to the well, is saturated with harmful substances. As a result, even pure water that has passed through it is saturated with pathogens.

Modern home water filtration systems are pretty good at dealing with these kinds of problems. At the same time, along the way, cleaning the liquid from excess iron, chlorine and other impurities, and even softening too hard. If we talk about pitcher filters, which are a budget option, they can be placed anywhere, they do not require a specific installation location. Of course, such a device will only be enough for one or two people. If there are more residents, then it is worth taking care to purchase a flow or storage water filter for the house. This acquisition may well provide several people with clean drinking water.

Even if the quality of water from a well or a well suits you, it is not always suitable for dishwashers or washing machines. Indeed, in any case, although rarely, some particles can get into it. For such cases, water treatment in a private house can be carried out using main coarse filters. They cost a little, but they also hold only fairly large fractions.

We will talk about the types of water filters for a country house, but for now we will figure out how things are with this in the apartments of Russian cities.

Do I need water purification systems in apartments with centralized water supply?

This question can only be answered unequivocally - it is necessary. With the rapid pace of construction of apartment buildings, as well as the lack of modernization of treatment facilities, the quality of tap water in our time leaves much to be desired. Water in the system requires purification from excess iron, chlorine, limestone, and sometimes even hydrogen sulfide and other rather harmful substances. Do not forget about the old age of communications. After all, rust from pipes also does not add purity. It is for these purposes that coarse and fine filters are installed in apartments.

Water purification systems for an apartment can be just as diverse, which means that choosing the right one in one case or another can be quite difficult. In this case, many parameters must be taken into account. Water filters in an apartment, as well as in a private house, can be classified according to various criteria, namely:

• By installation method– accumulative, main or flowing;
• According to the degree of purification- it can be coarse or fine;
• According to the fundamental structure- cartridge or disk.

Also, filters for water purification in apartments and private houses are distinguished by the method of purification, of which there can be a lot. Today we will definitely analyze each of them in detail, but first things first.

To begin with, let's try to figure out the classification of water filtration systems for apartments and private houses.

How water filters are arranged and their classification

First you need to understand how water filters work. Depending on the number of degrees of purification, the water in them passes through the elements (there can be from 1 to 5), which trap certain contaminants or saturate it with the necessary substances. Most often, with a five-stage purification, the water to the last of the elements is almost distilled. At the last stage, it is saturated with salts and minerals in the amount necessary for a person.

If we are talking about jugs, then such a household filter for purifying tap water combines all stages in one cartridge. At the same time, it is very important to choose a filter element with exactly the qualities that are needed. Otherwise, the water will not be purified as it passes through the cartridge.

Important information! Filters for water purification from wells must necessarily be equipped with coarse cleaning elements. If such water is poured directly into the same filter jug, then its cartridge will instantly become clogged with larger particles that will prevent it from performing its functions.

Classification of water filters by installation method

Filters for water purification can be installed on the inlet pipe to the living room (main) or directly under the sink (flow or accumulative). At its core, a flow filter differs from a storage filter only in the presence of a special tank in the latter. Such devices allow you to use purified water for some time even if its supply to the system is stopped.

Now our main task will be to understand what kind of work each of these devices does, what difficulties can arise when installing such equipment, and what you should pay attention to when purchasing.

The nuances of using main filtering devices

The main water filter for a private house is considered preliminary. Of course, it purifies water from sand particles, and some models are able to remove harmful microorganisms, soften water and improve its taste. But it should be understood that such installations will not be able to clean to the extent that flow or storage type devices will do.

Important! Main filters for water purification in an apartment are recommended to be used in conjunction with flow filters. In this case, the water quality will be ideal. However, with a small amount of pollution, such installations can quite cope with filtration alone.

A rather significant advantage of main filters is the presence of a water pressure regulator in them. You should definitely pay attention to this when choosing and purchasing. The pressure regulator allows you to extend the life of not only faucets, but also household appliances such as washing machines and dishwashers. The regulator eliminates the danger of water hammer that occurs when the pump is turned on, which are detrimental to household appliances.

The maximum number of purification levels for main filters is 3. If a device with one degree is selected, then here we can only talk about the removal of large particles, such as sand and rust. Such filters require replacement of cartridges at least once every six months. In addition, they should be washed periodically, especially with sufficiently dirty and “rusty” water.

Features of flow and storage water treatment devices

The most common location of such filters is under the sink or not far from the faucet on the wall. It all depends on the availability of the tank and its volume. Until recently, plants with five stages of purification were considered the most effective, but now there are even models with six.

Flow filters for water purification in apartments are usually equipped with an additional faucet, which is mounted on the sink next to the main one. At the same time, if main filters are installed on both hot and cold water, then flow filters are more often installed only for drinking water.

Important information! Not all flowing water filters for private houses and apartments are capable of operating at normal pressure in the water supply system. Some models require an additional pump installation. This is the only way to sometimes create a water pressure of 2.5-3 atm., Necessary for the normal functioning of the cleaning device.

And here is how netizens respond about one of these devices of the Aquaphor brand:

olga655, Russia, Koryazhma: After installing it in 2013, we used water for cooking and drinking, it has been used for a long time, we changed the filter only in April 2015. We coped with the installation easily on our own, it is advisable to treat the connecting hoses with a sealant to prevent leakage. From the company Aquaphor, fast delivery was ordered from the site. The support service is fast and efficient. The only drawback is that the faucet began to flow after six months. Convenient flow design. Did not regret the money spent. We change the filter cartridges every six months, the water has ceased to be hard, it has become pleasant to the taste, it has ceased to wash the kettle from scale every day.

Classification of devices according to the degree of purification

Here we can distinguish 2 possible degrees - it is coarse and subtle. Surely the designations of the degrees themselves speak for themselves, but it’s still worth considering devices with different cleaning for a more complete understanding of all the nuances of the choice.

Important information! When installing a filter with multi-stage cleaning, one should not think that its first stages, which are considered coarse, can function for a long time without installing an additional main filtration device or at least settling tanks directly after the emergency taps.

Coarse water filtration devices

Such devices are a fine mesh that can trap particles. These devices can be either washable or non-washable. A feature of coarse washing filters is that they have a special tap. By attaching a hose to the fitting and opening the valve, you can drain all the dirt contained in it. This makes cleaning the mesh easier. If you pay attention to non-flushing ones, then they do not have such a function, which forces you to periodically disassemble the device and clean the grid. It is to such coarse water filters that sedimentation tanks can be attributed, which are available in almost every apartment or private house. They are installed directly behind the emergency tap or water meter. Such elements are also called filters for the purification of industrial water, which contains many large particles.

Important information! Even if the water in your apartment or private house meets the standards, then no one is immune from sand, lime or rust getting into it. And this can have a detrimental effect on household appliances connected to the system. It is for this reason that the installation of coarse filters is necessary.

Fine water purification: how it is achieved

The main task of devices that carry out fine cleaning is disinfection, iron removal and softening of water. Separate devices can have the functions of aeration, ionization and adding the necessary salts and minerals to it.

In fact, a great job is being done with fine water filters for apartments. First, various elements gradually purify water to a distilled state, and then give it the necessary properties and taste. Of course, such devices require periodic maintenance and replacement of filter elements, but this is a secondary issue. But at the same time, the quality of water (with the right selection of cartridges) becomes close to ideal.

Most often, the installation of filters for fine water purification is carried out by specialists, although, having some knowledge in this area, you can install them yourself. You can find information on how to do this in one of our articles.

Important! When purchasing such devices, pay attention to the terms of the warranty. Some manufacturers will void their warranty if they install it themselves. Their requirements contain a clause stating that installation should be carried out only by qualified specialists.

The difference between filters according to the principle device

According to the principle device, such filters can be divided into cartridge and disk filters. We can only say that the latter are used much less frequently, although they are in no way inferior in terms of characteristics to the former. But this applies only to rough cleaning. It is for this reason that such elements are applicable only for the main type of devices. Let's try to understand what are the fundamental differences between these filters and what is their principle of operation.

Cartridge filtration systems and how they work

With such systems, everything is more or less clear. Water passes through tanks filled with various substances, which first purify it from impurities of one composition or another, and then bring it to the desired state.

Activated carbon is traditionally considered the main element of fillers for cartridges. It can be cheaper (birch) or high cost (coconut shell charcoal). Various chemicals and minerals can also be added.

If we talk about rough cleaning, then often a winding of the thinnest metal wire or thicker cotton thread is used as a filter element in the cartridge. Such a material is quite capable of retaining particles with a size of 20 microns. This is enough to filter the smallest dust particles, sand or rust.

Cartridge water filters have one drawback - the elements must be replaced after a certain period of time. And if at the same time more expensive and high-quality models are chosen, then such a replacement can result in a decent amount. But at the same time, the range of cartridge filters for water purification is quite large, compared to disk filters, which we will now also dwell on in more detail.

Features and composition of disc filters

Less common, but not inferior, and in some cases superior in performance to the previous elements. The filter itself is a bag containing many polymer discs. On their surfaces are notches in the form of a trapezoid. Thanks to such design features, under water pressure, a kind of mesh is formed, which traps small particles.

The peculiarity of such an element is that in case of clogging, it is enough to rinse the bag under running water, squeezing and unclenching it a little. At the same time, all the dirt accumulated in the grooves is removed and the filter is ready for use again.

Here are some technical characteristics of disc water filters.

Table 1. Characteristics of disc water filters

Thus, it becomes clear that all cleaning performance is identical to the characteristics of the cartridge elements. In addition, in our time, the manufacturer offers similar filters with automatic flushing, which is quite convenient.

How filters are separated by cleaning method

There are quite a lot of types according to this parameter. This:

• Mechanical cleaning filters;
• Ion exchange devices;
• With reverse osmosis;
• Aeration installations;
• Ozonation systems;
• ultraviolet;
• Coal.

Which filter for cleaning is better to buy, everyone will have to decide on their own, but we will try to help with the choice. And for this it is necessary to more fully understand which of the household filters for drinking water purification is intended for what and what functions it performs. Of course, the purpose of some elements can be understood already judging by the name, for example, such as filters for hard water for a private house. But many varieties are not so simple, so let's start.

Mechanical water filters and their purpose

Mechanical cleaning is most often called primary, coarse filtration. All main filters can be attributed to this type. Let's try to understand which manufacturers present goods from this segment on the shelves. The most popular brands here are Atoll, New Water, Geyser and BWT.

Table 2. Popular mechanical water filters

Make and model	Photo	Filtration speed, l/min	Maximum pressure, atm	Cost, rub
Geyser 1P 3/4 32009		10	7	9000
Atoll AFR-1/2CB (set of 2 filters)		25	16	10000
BWT Protector Mini 1/2 H604R11		27	16	5000
PRIO New Water A082		15	26	6000

As you can see, the price range is quite large. And that doesn't necessarily mean lower quality cheaper products. The point here is more about the brand and its recognition. After all, at first any company works for a name, and then, regardless of the quality of its products, the name works for it.

In general, mechanical filters for water purification nowadays are sold out very quickly. From conversations with the seller of one of the outlets specializing in such a product, we were able to find out that most often a queue of people who want to purchase main filters is already formed by the weekly delivery. At the same time, there is not enough such products for the whole week.

Ion exchange filters: how they differ from the rest

• Ultra-high level of cleaning;
• Removes all bacteria, heavy metals and viruses;
• Removes dissolved gases of residual chlorine, petroleum products, pesticides, phenol, hazardous metal compounds and other toxic substances;
• Household filters for softening water retain the mineral composition in it after cleaning;
• Stabilizes the pH level to the optimum for humans;
• Helps water to be charged with negative ions;
• Converts organic salts for easy absorption by the body;
• Provides high filtration speed, up to several liters per minute;
• Durable to use cartridges and easy to replace them;
• Has a variety of options for installation;
• Allows visual control of the degree of contamination;
• Provides the possibility of setting additional degrees of purification.

In fact, ion exchange is water purification by replacing heavy metals with neutral ones. Of course, we will not go into a full course of chemistry, but consumers consider this method to be quite effective. On average, the cost of such filters in the Russian market stopped at around 1500-3000 rubles. However, you can also find premium models at a price of 90,000-100,000 rubles. The main manufacturers are still the same - Aquaphor, Geyser, New Water and Barrier.

Reverse osmosis filters for the home - the most common type

Such reverse osmosis devices for water purification are installed under the sink or above it. The quality of cleaning systems with reverse osmosis reaches 99%. The cost of such devices is distributed as follows.

Table 3. Atoll filters

Make and model	Photo	Productivity, l/min	Number of cleaning levels	Price, rub
Atoll Patriot A-550		0,09	5	8000
Atoll A-310E/D-30 STD		2	3	5200
Atoll A-211E/D-21 STD		3,8	2	5000
Atoll Premium A-560Ep/A-550 MAXp		0,18	5	22000

Table 4. "Aquaphor"

Aeration system - what is it

The name itself speaks for itself. Aeration means saturation of water with oxygen. Many may ask - how is oxygenation related to filtration? The answer is simple. Aeration by itself does not purify the water, but with the help of other substances, by saturating it with oxygen, it helps to improve the quality of the final result. For example, aeration of water from a well improves not only its taste, but also increases the level of oxygen in the blood, which has a positive effect on human health. Surely many people know what an “oxygen cocktail” is. This same principle is applied here.

The use of a water aeration system is indicated for people with heart disease, hypertension and hypotension, as well as diseases of the gastrointestinal tract. But, in any case, you should first consult with a specialist.

Ozonation: what is the principle of such a system

Surely every student knows that ozone promotes oxidation. That is why water in some cases is purified by ozonation. So it is directed to a greater extent on iron removal. If there is no excess of iron in your water, then such cleaning is clearly useless. Ozone increases the intensity of iron oxidation, as a result, the particles begin to become covered with additional processes. In simple terms, they "rust". Having increased, such particles can no longer pass where simple water seeps freely.

Important information! Water ozonation is contraindicated for allergy sufferers. Ozone, in addition to its main work, partially remains in the water. As a result, an allergic person, consuming such water, automatically increases the risk of a reaction.

Whether ozonation is beneficial or harmful - this issue should be left to the competence of the doctor. But reviews of such devices speak volumes.

Denissasha, Ukraine, Chernivtsi: Ozone, in acceptable concentrations, has a lot of useful properties. You can ozonize drinking water, air, process food, places of cuts, burns and trophic ulcers. Ozonation of water and products is safe, all microflora and microfauna die in water, even those that survive chlorination, and the remains of drugs, hormones and other gifts of great chemistry are washed out of meat during processing. It has been verified that the processing of homemade village chicken practically does not give results, chicken meat bought in stores after processing is almost always covered with nasty mucus that must be washed off. How, what and how much to process is written in the instructions for the ozonizer. More on Otzovik: http://otzovik.com/review_167392.html

Ultraviolet and its effect on the body

Here we can say with confidence that such devices quite effectively fight pathogenic bacteria and microorganisms. For example, we can cite UV lamps that can be seen in the treatment and operating rooms of clinics and hospitals. Like them, ultraviolet water filters completely disinfect the liquid. But there are also negative sides. All useful substances contained in the water also die.

Carbon filter and its properties

Coal itself is an absorbent substance. This means that any resins, formaldehydes and other similar substances are retained by them. Today, the carbon water filter is considered the best in terms of cleaning.

In fact, if you think about it, no cartridge can do without such a layer. This suggests that the use of a carbon filter for water purification provides purification from the most common harmful substances.

The average cost of water filters in private homes

Prices for water filters in private houses and apartments may vary. If we compare the most famous manufacturers, we can understand the average dependence. An example is reverse osmosis filters.

Of course, all prices are given in the average equivalent, but this table is able to show an approximate concept.

It turns out that buying a water filter for a country house, cottage or apartment is not so difficult. After all, the cost of such equipment is low. And in general, is it worth saving on health?

The purity of the water entering the apartment determines the quality of our life. Hearing about the change in the environment and the deterioration of drinking water, many people think about what this life-giving moisture actually carries and how to protect themselves and their loved ones. The right decision is to purchase a water filter with multi-stage cleaning, which will get rid of dirt, chlorine, scale in the kettle and put a reliable barrier against heavy metal ions, pesticides and pathogenic bacteria. The rating of 10 models of water filters for washing will help you choose the option that is suitable for the price and quality.

The results of studies and tests of bottled drinking water conducted by Roskontrol showed that it often does not meet the standards and sometimes does not differ from tap water, which means that the use of household cleaners is becoming especially relevant.

Filters for washing: types

Among all cleaning devices, they are expensive and relatively difficult to install, require free space under the sink and regularly change cartridges. But, as professionals in this field note, it makes sense to spend money on a stationary filter once in order to get an uninterrupted source of clean water in the house with a convenient separate tap.

Let's find out what features a sink filter has and how to choose among the variety on the market.

The main difference is in the principle of water purification. Such installations are divided into 2 main types.

Flow system with stackable cartridge modules

Such devices have a multi-stage design and consist of 2, 3, 4 or 5 modules through which water passes in series. The cartridges located in them perform various functions:

• delay mechanical pollution (sand, rust from pipes);
• eliminate chlorine, unpleasant odor;
• remove excess metal salts;
• soften hard water.

Advantages of flow filters:

• low cost;
• clean water immediately comes from the tap;
• the ability to control the functionality of the system by selecting filter cartridges suitable for a particular case.

The disadvantages include the following:

• as the cartridges are used, the resource is exhausted and the quality of cleaning gradually decreases;
• each cartridge module removes some specific contamination and does not 100% clean all possible harmful impurities.

Attention! Multi-stage installation requires good pressure in the water supply.

reverse osmosis system

Such a device also performs multi-stage cleaning, the main difference is that the final processing takes place using an osmotic membrane, which removes all harmful impurities at the molecular level. At the outlet, the filtering unit produces the purest, oxygen-enriched water, discharging the filtered dirt into the sewer through the drainage tube.

Advantages:

• the most effective purification from all possible impurities;
• the quality of cleaning is constant, always at the highest level and does not depend on the exhaustion of the resource of the cartridges.

Features that can be attributed to the disadvantages:

• Low rate of obtaining purified water, due to which such filters are equipped with additional tanks with a volume of 8 to 12 liters. This will require more space under the sink.
• With harmful substances, almost all salts are removed from the water, so you need to select models with mineralizers that saturate the liquid at the exit with useful microelements.
• To clean with a reverse osmosis membrane, you need high pressure in the pipes, so some models are equipped with a built-in pump (pump) that automatically turns on if the pressure is below the required level and fully carries out the cleaning cycle. Naturally, they cost the consumer more, especially foreign products.

Price - from 2,328 rubles.

In the Aquaphor line of budget devices, this is the most popular model. Equipped with three stages of purification, including carbon filtration and ion exchange. The unit is able to purify water from harmful impurities and perform microfiltration of particles up to 0.1 micron in size.

Productivity - 2 liters per minute.

Resource of the filtering module - 6000 l.

• low price;
• compactness and efficiency;
• separate faucet included;
• easy installation;
• replacement of the filter module with the housing is carried out quickly and without interference;
• the filter for softening water is regenerated according to the instructions when the quality of cleaning decreases.

• a small resource of filters, scale in an electric kettle with very hard water appears quickly enough;
• some users do not like the taste of purified water.

Price - from 5 360 rubles.

The company "Barrier" has its own research and production laboratory, constantly introduces new high-quality products to the market and therefore is in demand among our customers. A popular model was the filter under the sink "Barrier Profi Osmo 100", which has a reverse osmosis system, five-stage processing, including coal.

Testing by Roskontrol confirmed that all the properties of the Barrier filters declared by the manufacturer are valid.

Main purpose:

• special cleaning from chlorine;
• deferrization of water;
• softening.

Very compact model among all reverse osmosis systems. It has four stages of cleaning. Supplied with in-line cartridges with quick connectors. Removes all harmful impurities by 99.9%, passes only water and oxygen molecules. It has a storage tank with a capacity of 8 liters.

• has the highest degree of water purification;
• easy to maintain;
• will fit in the narrowest niche, the size of the pre-filter block is 360x190x160mm, plus the tank size (height / diameter) 370x240 mm.
• the optimal ratio of the cost of a liter of clean water, if you consume 10 liters of clean water daily for two years, the filter will pay off in a year and a half and the cost of 1 liter of clean water will be about 2 rubles.

Fits in a standard niche, even with a chopper installed.

When choosing a filter for washing, first of all, you should pay attention to the features and properties of water in your home. And only then, focusing on a specific brand and taking into account all the diversity presented on the filter market, choose the appropriate system.

In an apartment building there is a centralized supply of hot and drinking water. Naturally, before submitting to the apartments, the main one was organized. However, it cannot be argued that after this the water is completely ready for use.

In order to get really clean water at the output, it would be better to use additional purification methods. Modern water purification systems for an apartment are presented in a fairly extensive range, so you should take a closer look at the current variations.

1 Cleaning methods

Usually, tap water treatment in an apartment has the same type of scheme, which shows the best results. It consists of the following stages.

At the first stage, it is better to install a mechanical or otherwise coarse filter. These are those that have polypropylene fiber cartridges. They clean these filters from suspension, iron, and sand.

The equipment is cut into the water supply and thus the running water is 100% purified. It should be remembered that for hot water it is necessary to use those that are resistant to higher temperatures. Such a system helps to extend the life of plumbing in apartments.

The second stage involves the purification of drinking and hot water from impurities of chlorine and metals. In eliminating these elements, it is very effective to use main filters with cartridges based on activated carbon.

The result will be noticeable immediately, as the water will acquire a pleasant bluish tint and the unpleasant chlorine smell will disappear. While taking a shower with purified hot water, the effect of tight skin disappears.

The third stage is needed in order to remove hardness salts, calcium and magnesium. This is necessary in order to get rid of raids on plumbing. Such filters contain softening cartridges and cut into the water supply to purify all running water.

The fourth stage involves obtaining clean drinking water. They are installed directly under the kitchen sink or.

Above is a water treatment, with which it is possible to obtain clean hot and drinking water. But you don't have to use all the steps. It is possible to combine filters, depending on which impurities should be eliminated.

2 List of cleaning equipment

You can offer different systems for purifying tap water, which are described below.

2.1 Advantages and disadvantages of filtering methods

Of course, each hot or cold water purification system has its positive and negative properties.

The advantages of filter jugs include their small size, simple design and low cost.

The disadvantages are the low degree of purification from impurities, the filter material has a short service life, as well as slow filtration.

Dispensers - can heat and cool water, have a larger volume of the vessel. However, they also have a low degree of purification.

Multistage filters are expensive. It cannot be guaranteed that it will completely purify water from bacteria and some viruses. The advantages include a large cleaning resource, it easily cleans from mechanical impurities of chlorine and its compounds.

Charcoal filters are usually made from coconut shells. Therefore, the main advantages are strength, low abrasion, long service life of more than a year.

The disadvantage may be that they are too large. Some carbon filters reach a height of 1 meter and a width of about 35 cm.

2.2 Which filter is better to choose?

To determine which filter is needed to purify the water of a given apartment, it is not enough to listen to the reviews of friends or acquaintances.

Of course, if funds allow, you can purchase a nanofilter that will make the water perfect and last for several years without replacing cartridges. If you choose economy options, then you can, depending on the composition of the water, select and arrange different filters.

When choosing, you should be guided by the following indicators:

• How many people live in the apartment, and how much water is consumed per day;
• What purchase price is acceptable;
• How clean water is expected at the output;
• It is better to analyze tap water and determine what impurities are present in its composition.

Finally, we should also mention reviews from people who installed water treatment systems at home.

Tatyana, 40 years old, Orenburg:

It is impossible to drink tap water without additional purification. I have been using the pitcher for a long time. However, I read reviews that it does not purify water well enough.

Now I'm thinking about buying a more serious system for cleaning, but so far I haven't made a final choice.

Ivan, 37 years old, Rostov-on-Don:

I have a multi-stage filter at home. I installed it myself, everything is very simple, now I don’t worry about the quality of the water.

Kristina, 41 years old, Kursk:

We used to always buy bottled water to drink. And then I read reviews that it might not be cleaned at all, but poured raw from the tap and decided to buy a filter. My husband put it under the sink with a separate faucet, so convenient.

2.3 How to choose a cleaning system for an apartment? (video)
