Some people generally doubt the appropriateness of installing a filter: since water for drinking or cooking from your well is not suitable, it is better to take it in stores, from a spring, and bring it from friends. It will be more reliable and cheaper. ⠀
⠀
⠀
⚠ Cheap filters will not clean the salt, and expensive filters will ruin, and it’s not a fact that they will normally clean. And the coefficient of their cleaning decreases every day until the next cartridge is replaced or the cleaning ingredients are refilled. ⠀
⠀
🗣 But, as our expert says, salts from water are completely removed and it is not necessary, they are necessary for our body. It is necessary to remove harmful and toxic substances, and the filter copes with this task perfectly if: ⠀
⠀
▪ choose it correctly; ⠀
▪ regularly replace cartridges (the cost of the kit is 100% in any case lower than the cost of the corresponding volume of bottled water). ⠀
⠀
The springs are affected by all the problems of the wells; they may contain various non-specific contaminants that cannot be detected with the naked eye. ⠀
⠀
🌊 If you regularly visit the spring, we recommend that you first take the analysis from it to the laboratory, and check at least 15 parameters. Most important: microbiology and organics, hardness, iron, manganese, nitrates, fluorides. In our experience, MPCs for nitrates are exceeded in more than 60% of springs, and in regions with active agricultural activity - by 100% .⠀
⠀ ☝ Conclusions: ⠀
⠀
So, when choosing a filter for washing, it is important that it is suitable specifically for your water. Therefore, first of all, you need to do an analysis, and then look at exactly what flaws need to be addressed.
⠀
➖ bad smell and color of water ⠀
➖ scum ⠀
➖ metallic taste and “rusty water” ⠀
➖ bacteria ⠀
⠀
Each problem is solved by a specific filter. ⠀
⠀
👍 It is also important that the name of the manufacturer is known - this means that he cares about his reputation, and the filter design is reliable and extremely easy to use.

Flow-through filters for washing are valued, first of all, for the speed of cleaning - consumers instantly get clean water. ⠀
⠀
🗣 Flow filters have two different cleaning principles. The first is sorption filters. They contain in various sorbents (coal, ion-exchange resin), which adsorb pollution on its surface. The second type is reverse osmosis filters with a membrane whose pores are passed only by water molecules. On this membrane, the water flow is divided into two parts: 20-25% goes to a tap of clean water, the rest goes to drainage. ⠀
⠀
❓ Which system is better? ⠀
Both have strengths and weaknesses. ⠀
⠀
The strong side of reverse osmosis is that it can purify water of virtually any initial composition to the H2O state. There is no alternative to reverse osmosis if you have a very high level of iron in your water (above 1.5 mg / l), nitrates or fluorides, a risk of radioactivity or microbiological contamination, including viruses. ⠀
⠀
➖ At the same time, according to the expert, this design has a number of disadvantages: ⠀
⠀
▪ Water after reverse osmosis filters is absolutely “empty”, it does not contain not only harmful but also useful substances. The use of such water without additional mineralization for a long time is unsafe for health ⠀
▪⠀
Water consumption increases four times, since only one part of the water falls into the tap, and 3-4 parts into the drain ⠀
▪ To “push” water through the membrane, a pressure of at least three atmospheres is required. If there is no such pressure in the pipes, a pump and electricity supply are required ⠀
▪ Such systems are more expensive ⠀
⠀
👍 Unlike reverse osmosis filters, sorption filters can clean ⠀
water only from those contaminants for which sorbent is in their composition. ⠀
⠀
👍 In this list, all pollution typical of tap water: chlorine and its compounds, iron and heavy metals, odor, color, suspended solids, hardness up to 6 mEq / l. At the same time, such filters are cheaper and less sensitive to water pressure at the inlet and leave macronutrients necessary and useful for the body in the water.

According to our expert, without analysis, only a few of the most obvious problems can be identified. They are collected in a small cheat sheet. ⠀
⠀
▪ Problem - ▫ Symptoms ⠀
⠀
▪ Availability of suspended particles - ▫ Turbid opalescent water ⠀
⠀
▪Hardness - ▫ Quickly formed scale on the teapot and film on hot drinks ⠀
⠀
▪ Iron - ▫ The water has a yellow coating and forms smudges on the plumbing ⠀
⠀
▪Sulfide - --Specific smell of rotten eggs ⠀
⠀
The problem is that most highly toxic substances (nitrates, fluorine, heavy metals) cannot be detected ⠀
by eye or by improvised means. Better to do a full water analysis. ⠀

💦 Features of filters for washing ⠀
⠀
Unwanted impurities can be eliminated from water at home by placing a three-stage drinking water purification system under the sink and connecting to the house’s water supply pipe (or cold water main). A separate faucet for purified water will need to be inserted into the sink or countertop. Water, passing through all three stages of purification in succession, gets rid of mechanical impurities, chlorine and organic and organochlorine impurities, heavy metals, undesirable tastes and unpleasant odors. ⠀
⠀
⠀
🌊 There are various options for completing a flow filter, and, depending on them, you can reduce the iron content and water hardness, as well as get rid of bacteria. ⠀
Self-locking systems have now been developed that do not allow filter elements to unscrew when the filter is even under strong pressure. Using the instructions, such a filter can be installed independently, in just half an hour. ⠀
⠀
Many are annoyed by the need to often change cartridges, but modern filters are designed so that there is no problem - all with one touch. There is no need to use a special key, rinse flasks and perform other tedious rituals. ⠀
⠀
⚠ The easiest way to change the cartridges is in a three-stage cleaning system - the operation takes 30 seconds and can be performed with one hand. Importantly, before replacing, do not forget to shut off the water! ⠀
