Water filter under the sink, a better ranking of the most popular models

The quality of tap water has long ceased to be sufficient to use it in food without further purification. Specific taste and smell of raw water can spoil the prepared dish, and drink it at all unpleasant. For this reason, many set in the kitchen of your house or apartment a water filter under the sink, what is better and what characteristics are important in the selection - consider in this article.

How to choose a water filter under the sink: the instrument features

The name speaks for itself about the specifics of the use of these devices. Filters of this type are installed directly under the sink in water pipes using special connectors. Passing cleaning water is discharged through a separate faucet mounted on the sink.

Another variant of the filter placement (in cases where the space under the sink is not sufficient) - wall mounting. Special flexible connection enables effectively connecting elements and supplying the purified water through the same additional valve on the shell.

An inexperienced user can easily get lost in the abundance of proposals which are on the market today. It is not enough that the companies producing very much, so more and each filter has some of its feature. Therefore, in order to facilitate the selection, consider in detail the three main selection criteria:

• the type of installed filter;
• manufacturing firm;
• choice of model.

water filter under the sink, a better variety of devices

In order to make the right choice, you need to be guided in the proposals that are on the market today. It is best to familiarize yourself with each of the device types to then purchase the one that best suits you.

All filters for drinking water under the sink are divided into two groups, based on their work: flow and water filters with reverse osmosis. Buy a better one that will be appropriate for your situation. Consider both options.

Filters for water flow type

Current models flow of filters passing water purification is performed in several stages. Generally, the process consists of passing three or four modules, each of which affects the quality of produced water. The main argument in favor to purchase flow-through water filter under the sink - the possibility independently change the cartridge packaging and handling, so that the extent and quality of cleaning. Among the most popular modules can be seen not only mechanical filters, but also those that purify water using small particles of silver or special sorbent.

Such filtering allows not only cleaned from mechanical impurities, but also to eliminate chlorine particles together with the corresponding odor and eliminate the unsafe microorganisms that can harm health person. Also, multi-level treatment makes it possible to deliver water from entering into it of pesticides, heavy metals, and even refined petroleum products, if any. All this can be controlled independently, by installing various types of cartridges.

Removable water filter cartridges are of the following types:

• cartridges for water purification from mechanical admixtures only;
• universal, which are suitable for normal water supplied through the water supply. They are well cleaned of all the most common impurities;
• Cartridges for very hard water cleaning;
• providing water purification, characterized by excessive amounts of metallic impurities;
• antibacterial, allowing to destroy microorganisms that can live in the water, including a variety of viruses, bacteria and cysts.

Considering the variety of options that are on sale, pick up and install the appropriate labor cartridges will not be. And although in the future they will require regular replacement, which would entail additional costs, you will be able to protect themselves and to ensure a clean and quality water.

Note! Identify exactly what the threat might be in the water, can only examination. To do this, you must include a sample for analysis, and then wait for the results, and only then begin to choose appropriate cartridges.

Household water filter under the sink reverse osmosis system

The second type of system uses the reverse osmosis principle. Externally, these filters resemble conventional sorption devices, but they have a significant difference: the number of additional units to allow better cleaning. Such modules may be several: from one to four, and in some premium models and five.

By themselves, they represent a plastic container, which is located inside the cartridge, but all together they constitute a complex treatment system. Considered mandatory component module, equipped with a reverse osmosis membrane which provides ultra-clean water.

The benefits of reverse osmosis filters for water purification under a sink include:

• high level of purification of various solids;
• the cleansing quality of various organic compounds, hydrocarbons, chlorine and heavy metal salts due to the presence of coal sorbent;
• possibility of purification of water from impurities iron.

Module equipped with a reverse osmosis membrane, the latter is always set in the circuit, and water is supplied thereto, after prior purification from mechanical impurities. Special membrane is arranged in such a way that its pores are able to pass only water molecules, while the larger particles remain on the outside.

However, it should be borne in mind that within such a membrane is required for the passage of water to the system pressure is at least 3-3.5 bar. For this purpose, the filter is often set optional special pump that pressurizes to a desired level.

Useful advice!Some models of such devices can be equipped with special ultraviolet lamps that allow to destroy microorganisms that can cause health problems, and completely disinfect water.

Such filters for water purification by reverse osmosis to give up water, the composition of which can be compared with distilled water. And its use, as it is known, does not have a positive impact on human health. Therefore, lack of minerals must be replenished artificially, using for this special mineralizer.

This occurs as follows: the water passes through the membrane at a low speed, which allows the use for this purpose a special tank. Usually, its volume does not exceed 10 liters. There the water is enriched with essential trace elements in the quantities that are needed. In addition, such a container much easier task if you suddenly need a lot of water, and the time to wait until it is cleared, no.

Considering all of the above, we can conclude that the reverse osmosis purification system the most advanced to date. The level of cleaning, they are able to offer, we can be compared to that practiced for the bottled water sold in the store.

Which to choose a water filter: characteristics of water and cartridges

Once you have an idea about each type of filter that can be installed under the sink, you need to make a decision in favor of options to make a choice. And, oddly enough, to be guided in this matter needed more on the quality of the water than on the technology itself of a filter.

In order to really represent a complete picture of the quality of tap water, it is necessary to apply to a special laboratory, which takes samples for analysis. It is important to realize that water - it is an individual matter, and its composition depends not only on where it is taken and how well cleaned, but also on the path that it goes after. Thus, rusty water pipes - a major source of mechanical impurity, and also a favorable habitat for many infections and dangerous bacteria.

In order to get a quality analysis of water, you can contact the sanitary and epidemiological stations, providing them with a clear plastic bottle filled with tap water. But in this case the results will have to wait a certain time. Another option - to carry the same sample in the test center. In this case, the service will cost more, but will do everything very quickly.

Water testing performed by thirty points to provide the most detailed picture of its quality. The greatest threat is the presence of radiation in the water. Also check the level of the presence of lime, iron salts and various organic components, which include pathogenic viruses and bacteria.

In addition, carry out analysis, which allows to determine the PH level of water, its degree of transparency, as well as compliance with the smell and taste standards. The results you get in writing, after which you can proceed to the choice of a suitable filter and cartridge.

How to choose the right cartridge

There are some basic rules that can make the right choice and choose the most suitable model.

If an excess of such substances in water was identified as chlorine, iron, or other chemical compounds, but at the same level of rigidity is correct, it is quite enough to be the next set cartridges:

• Cleaning by mechanical impurities;
• sorption, which comprises activated carbon;
• for removal of iron impurities.

If the analysis showed that the level of hardness of the water exceeds the norm, it is necessary to take care of even the existence of a mitigating cartridge. However, more effective in this case are not considered flow filtersAnd systems equipped with reverse osmosis function. The role of the softener performs reverse osmosis membrane.

Removal of the water of various microorganisms and should be paid special attention. They are able to have a negative impact on human health. And here, again, can help reverse osmosis system is equipped with a UV filter, which is designed to destroy even the smallest micro-organisms are able to penetrate through the pores of the membrane.
