Mankind has long paid great attention to the water.We all know that without water there is no life on earth.Dry grain can lie for years in the ground, but grows only when there is moisture, which lives grain.Despite the fact that water is the most necessary and widespread distribution of the substance on the ground on his globe it is not even.So in Africa and Asia, water is very scarce.It contains vast areas of dry land, a desert.Even countries live on imported water.So Algeria in order to fully provide itself with water it brings from other countries.Just deliver the water and some coastal areas of Greece.Often there is water costs more than wine.According to estimates of the United Nations since 1985, 2.5 billion people of the world have begun to experience a strong lack of drinking water.
water in the human body
We know that people in the 65 percent water.Embryos are composed of 97 percent water.In a healthy body there is equilibrium balance water.During aging the water content in the body is reduced.In order to balance the water was OK, we need to consume daily to 2.5 liters of water.But not all water is useful.It has long been known that water from the tap is not acceptable for use in crude form into the body.Theoretically it can be assumed that the water comes from the tap you fully corresponding state standards.But unfortunately all know that when you come to us, water is again contaminated, both physically and awareness.This is due to the state of the pipes and passing tracks.It should be protected, filtered and purified.It is a long process that takes a day or more.To have to stock tanks in which the water is purified and defended.This is troublesome, inconvenient and not very hygienic.Fortunately nah age of technology there is a way.It is a variety of water filters.
Water filter jug
How it works.
poured water into the jug by gravity flows from one container to another, while it passes the sorbent bed is filtered.
Pros.
This type of filter does not require connection to the tap is very easy to use, and does not require the presence of human control during cleaning.Suitable for offices, apartments, villas, rooms in which there is no centralized water supply system.
Cons.
degree of purification, a little lower than that of water purifiers, which are connected to the water supply.The volume of purified water is the same as that of the jug (typically 1 - 2.5 liters).If you will need more water will have to fill the pitcher 2, 3 or more times.
water purifier on the tap head
How it works.
This purifier is put on a faucet.The water passes through it.
Pros
low cost.Small size (convenient for water to travel).
Cons
Unfortunately, a very small amount of sorbent, because of this low productivity (0.3 - 0.7 l / min) (if you are told that it will be possible to filter the water quickly - do not believe it's not possible).Just have to use a container for storing the filtered water.You will constantly disconnect and connect the filter to the tap unless it is equipped with a switch.
filter, which is mounted on the sink
How it works.
filter is put not on the crane itself, and is located near the filter is attached to the crane flexible hose, the water passes through it is filtered.
Pros.
Good performance of pure water (1 - 1.5 L / min).There is no need to separate containers for the filtered water.
Cons.
take up too much space on the sink.Unfortunately, this filter should always be connected and disconnected after each filtration.
