From under the tap, running water is like a puddle. It “flowers” in a riotous color symbiosis of minerals, rust, chlorine, microflora, and microorganisms. Use it for watering – wherever it goes. Drinking is more expensive, dysbacteriosis and poor health are provided.
The water treatment filter solves this problem. Which is better to buy, understand after reading this article.

How do I know the quality of the water at home?
Before you choose a water filter, you need to understand what it should fight. It should be remembered that household testers will show only long-term results, and no one is immune to its “false-negative” results: when the test does not work properly. And only a chemist will understand this, and the average person will take the result for granted.
Therefore, it would be better to give water samples to the laboratory to check the quality. There are two options for the development of events.
- Self-to-collect water in a clean glass container (plastic can further contaminate it) and bring it to the nearest sanitary station (SES) – a budget, but time is expensive.
- Calling a specialist from a private lab is more expensive but faster.
The lab may offer a comprehensive test, while SES may not have the right reagents, will have to take the water for the test several times.
The conclusion will indicate the main 6 parameters of water:
- stiffness is an indicator of the level of alkaline-earth metals in water. The fewer of them, the better. Ideally up to 7 mg-eq/L;
- acid-alkaline balance – within 6.5-8.5 Ph – such water is considered clean and usable;
- Organic impurities ratio – live organisms and their derivatives are present in the water: spores, seeds, bacteria, microbes, etc.;
- conductivity – how much water holds salt. The higher the indicator, the salty liquid. The standard figure is 300 to 1200 s/cm;
- mineralization is how many minerals there are in the water. Demineralized water is not suitable for drinking, as it will wash minerals out of the bones. The average drinking water is 800-1200 mg/l;
- inorganic impurities (lead, mercury, radon) – whether there are substances in the water that do not belong to organics.
How to calculate the daily use of drinking water?
The right amount of water correlates with weight. Doctors advise drinking 250 ml of clean water for every 8 kg of weight. Fragile, weighing 60-65 kg, will be enough 2 liters of water, but 110 kilograms will need almost 4 liters. As a result, the average family of 3 people will consume at least 10-15 liters per day, 70-80 liters per week, or 300-350 liters per month. And it’s just for a drink.
Based on the above numbers and water quality, it is worth choosing the right filter. Here’s how much capacity you can for each type of filter.
|Filter type||The Ability to Clean in litres||How Many Months Can a Family of 3 Be Used|
|Reverse osmosis||3 000-6 000||10-20|
|Sorption||3 500 – 8 000||10-25|
As you can see from the table, on average, it is desirable to change the filter for the house once a year and a half. The reason is that over time it accumulates “waste,” and the device will work worse.
Types of filters by design: 3 common
1. Pitchers are the most primitive kind
popular due to ease of use and compactness. The device is convenient to take with you wherever you go. If you change the filter on time and clean the container, you can use it for years. The working principle is simple – water is fed into a funnel with filters, and passing through it, cleaned.
2. Flow – A filter cartridge is installed in a pipe under a
water tap and will undergo multi-stage filtration before entering the faucet. The installation will require plumbing skills, so it is better to call a specialist for this case. An example of a good filter is the BRF0228 Breeze.
3. Nozzle on the faucet – the filter is installed on the faucet
itself. Such devices come complete with a universal mount, so “climb” on any faucet. You can install yourself without the help of plumbing.
Types of filters by the cleaning method
The filters differ in the way they are cleaned. The state for mid-2020 is in-demand models, collected in the table below:
|Filter Cleaning System||How it Works||Features|
|Mechanical||Water passes through a filter that sorbs insoluble elements||Remove sand, dirt, rust and prepare the water for the next cleaning. Most commonly used in wells and wells|
|Cartridge||The water passes through the cartridges (replacement containers) and is cleaned||Makes clean in composition even boiling water (not all models)|
|Disk||Inside the filter case, there are many discs with grooves the size of several dozen microns. It is on them and the space between the discs passes water||The most environmentally friendly filter, which does not harm the nature of the garbage produced.|
To maintain cleanliness, it is enough to wash every few weeks under the jet
|The fall asleep||A column filter with a water valve, which is filled with filtration materials at the discretion of the manufacturer||Cleans muddy water from wells|
|Ion exchange||Ionites (materials inside the filter) capture from the liquid ions of stiff salts and replace them with their own||Noticeably softens the water|
|Reverse osmosis||It filters out more than 99% of the pollution. Water passes through 3 cartridges of different stages of cleaning:||The filter completely removes all the “contagion”, so water after cleaning can be drunk even the smallest.|
|A 5 micron-sized membrane cartridge absorbs impurities||The first two cartridges will have to be changed every 3-4 months, and the block will have to be changed once a year|
|Coal – cleans from chlorine and organics|
|Carbon block absorbs odors|
Filter cleaning system
How it works Features
mechanical water passes through a filter that sorbs insoluble elements. Remove sand, dirt, rust and prepare the water for the next cleaning. Most commonly used in wells and wells
Cartridge The water passes through the cartridges (replacement containers) and is cleaned. It makes clean in composition, even boiling water (not all models)
Disk Inside the filter case, there are many discs with grooves the size of several dozen microns. It is on them, and the space between the discs passes water, The most environmentally friendly filter, which does not harm the nature of the garbage produced.
To maintain cleanliness, it is enough to wash every few weeks under the jet
The fall asleep A column filter with a water valve, which is filled with filtration materials at the discretion of the manufacturer, Cleans muddy water from wells
Ion exchange Ignites (materials inside the filter) capture from the liquid ions of stiff salts and replaces them with their own Noticeably softens the water
Reverse osmosis filters out more than 99% of the pollution. Water passes through 3 cartridges of different cleaning stages: The filter completely removes all the “contagion,” so water after cleaning can be drunk even the smallest.
A 5 micron-sized membrane cartridge absorbs impurities. The first two cartridges will have to be changed every 3-4 months, and the block will have to be changed once a year.
What to look for when choosing a water filter?
First, you need to decide what the filter is for; otherwise, it will not meet your expectations. The filling is not suitable for apartments; chlorine does not absorb. And the filter of reverse osmosis is not designed for wells because the water will have time to feed on substances while it will go through the pipes in the house.
To find a suitable option, you should pay attention to 5 parameters.
Easy to replace components
Will it be possible to do it yourself.
In a 6-8 people family, you have to change the pitcher’s cartridges every week. One or two potential sorbents will last for a month.
Before drinking water from the jug, you will have to wait 3-5 minutes until it is cleaned. Flow models clean instantly.
The degree of cleaning
If the user drinks only bottled water, it will suit cartridge and ion exchange models, removing metals and microorganisms and softening the water.
The need for regular washing
Some are enough to replace the new, the second need to be regularly washed and installed back.
The importance of using water filters
Our body is made up of 80% of water. Therefore, vivacity and well-being directly depend on the quality of the fluid drunk. If you regularly drink at least two liters of clean water, it will be easier for the body to maintain immunity in tone.
Drinking clean water improves well-being, skin, nails, and hair – they are imbued with moisture from the inside. Distilled water doesn’t count. It lacks minerals, and the level of Ph is noticeably below the norm (oscillates between 5.4-6.5, which is commensurate with coffee or tea). Only clean water saturates the body to the fullest and grants health.
Before you choose the right filter for drinking water, you need to know its
indicators. If they fit the set tasks – you can safely take them!
