Choosing a water filter - types , characteristics and purpose

water quality in our water pipes has led many to think about the purchase of water filters.But their great variety in the market of modern water-treatment devices often puts consumers in a deadlock when selecting a desired device.This problem can be solved simply, if you know the selection criteria and parameters, characteristics of the main types of filters, the characteristics of their work.

What to consider when buying a water filter?

Before heading to the store to choose and buy a water filter, say for yourself a few questions:

1. From what filter must purify water? The water may contain many different impurities adversely affecting the body chlorine, bacteria, lead, fluorine compounds, rust and others.To resolve this issue, you need to send a water sample for analysis in the laboratory.The cost of this analysis depends on the number of relevant indicators: for abbreviated analysis (indicators 10-12) you give 900-1200 rubles for advanced (15-40 indicators) - 1800-4000 rubles.After receiving the results, you can show this document to employees of the company, which will buy the filter, and they will help you choose the option best for the composition of your water.
2. What you need purified water? It depends on the number of people in the family and the total demand for clean water.Filter-jug may well provide a family of 2-3 people with drinking water.If the family is large or purified water is required not only for drinking but also for other purposes (washing, dishwasher and washing machine), it is better to install a permanent filter.
3. What price you can pay for a filter and supplies it? Water filters of different types differ in their performance, and value.Think about how you prefer: to invest in expensive high-quality water purification system or buy an inexpensive filter and change it periodically cartridges.

main types of water filters, their characteristics

Filter-jug

Device type pitcher nezateyliv structure and inexpensive.It consists of a volume of 1.2 liter jug ​​and filter installed inside the water tank to be cleaned.The jar is inserted into the tank, it is poured into water, which gradually passes through the filter and purified of impurities flows into the jar capacity.

This type of filter can solve the following problems:

• purify water from mechanical impurities;
• reduce water hardness;
• to reduce the water content in iron, copper and chlorine.

Advantages jar filters:

• lowest price;
• ease of use;
• no installation problems.

Disadvantages jar filters:

• not very high degree of purification;
• cartridge yield little;
• filter element can not be regenerated.

flow

filter The filter can be connected to the faucet either permanently or as needed.In terms of functionality, they are close to the Filter-jug: purify water from mechanical impurities and chlorine.If the activated carbon based filter, it removes water from bacteria, microorganisms phenol.Filters with ion exchange resins the purified it from iron, heavy metals, aluminum, hardness.

Benefits flow filters:

• ease of use;
• compactness;
• fairly good degree of purification;
• easy installation.

Disadvantages of filter-tips:

• short life of the filter elements;
• relatively high price of consumables;
• filter of this type does not relieve you of all the water problems.

Multi-stage water purification system

If the water in your plumbing needs serious and thorough cleaning, you should consider purchasing a multi-stage system, which has at the heart of the reverse osmosis membrane.Such systems are required, for example, in the case of very hard water.

reverse osmosis filters can contain a different number of treatment steps (usually 4 or 5):

1. purification from mechanical impurities.
2. Removal of chlorine and its compounds from the gas.
3. Fine cleaning from mechanical impurities.
4. Clean thin-film membrane.
5. Carbon post-filter.

multistage systems Advantages:

• water purification at a high level;
• solution of all complex problems related to water quality.

Disadvantages multistage systems:

• high cost of the system and consumable items;
• complexity of the installation;
• large water consumption (for 1 liter of pure water requires about 5 liters of water from the tap);
• large.

Too high degree of purification someone can be attributed to the pluses of the system, and someone and cons.Indeed, multi-cleaning system shows virtually distilled water, purified of all impurities, including, and useful for humans.To solve this problem, the water can be independently enrich trace elements and salts or buy a filter with a mineralizer.

main filter manufacturers for

water most famous in our country, manufacturers of filters for water are the companies: Aquaphor, Ariete, Binatone, Brita, Nivona, Great River, Barrier, Geyser, New Water, etc.

filters cost.it is very different.It depends on the type of filter cartridge service life, speed and degree of filtration.For example, a filter jug ​​Brita worth more than the same devices from other manufacturers, but this filter cartridge last much longer than others.In addition, it has an indicator showing what the remaining life of the cartridge.

So which filter to choose?

for one user or a family of 2-3 people can be enough filter pitcher or a nozzle on the faucet.If a large amount of purified water is required, it is better to take care of high-performance stationary filter.

correctly selected filter for water will bring your family's health and longevity, because the water - it is important for the person, and the water quality is largely determines the quality of life.
