Those times when water from natural sources could be safely used for household needs and drinking, have been passed for a long time. Pure springs are still found in nature, but for a city resident such crystal pure water is almost fantastic, it may be found in the store, but you should definitely not expect to expect from the water supply. Water supply is generally history, by the way, a separate. It is even interesting how the use of those who supplies us with this water imagine – rusty, muddy and smelling of chlorine is impossible to drink even after boiling, since it can only kill living microbes, the high temperature does not remove harmful elements and suspensions.
Before getting to our houses, water makes a long way. First, it is pumped into large tanks from underground sources, in them – cleaned of solid precipitation, softened and disinfected. Most of the harmful substances contained in water, all these procedures, of course, are removed, but not all. Further to the houses, water is distributed using the pipeline. The communal economy is far from what it was in the days of Soviet, some pipes have been used for many years, very covered with mold, crocheted and rust. On the way to us, the liquid from their walls is saturated with bacteria, fungi, various trace elements, sand and scale. It is not only not only useful to eat such water, but even dangerous. It is unlikely that there will be those who want to voluntarily harm their health and destroy the organs by using such water.
Suffer from bad water, by the way, mostly large cities. The fault of production enterprises and treatment facilities, which are dumped into natural reservoirs, a large number of waste waste, not always bothering to make them pre -safe for the environment. In such conditions, water filters become a real salvation.
There are three main types of water filters in total: these are tap nozzles, accumulative filters and built into the water supply. The most effective, but difficult to install are the last. They are usually installed by experts, mounting under the sink, connecting with a common water supply and withdrawing a separate crane for them, from which clean water for drinking and cooking will flow. Such filters work by cleaning water with special cartridges.
