Choose a water filter

Bad taste, lime excess, fear of pesticides and nitrates, you want to treat your tap water.What you need to know to adopt the system that best meets your needs.

Filter or not filter its water: that is the question ...

Periodically, researchers are concerned about the quality of tap water and in particular its pollutant content that they believe may explain some cancers. Hence their recommendations, especially to the sick, drink bottled water or filtered water.

A precautionary principle against which amounted Medical Academy and the Academy of the water reminded that the tap water was one of the most monitored components, the healthiest and safest food we eat. Anyway, nothing prevents you want to filter your water , especially if it is particularly chlorinated or limestone. You have three options.

Filter jug: the most economical

The principle of this type of water filter? Placing a cartridge composed of activated carbon and resin beads that will capture pollutants (lead, nitrates, certain pesticides) in the center of a funnel-tank which is then filled with tap water. When using this last spring carafe filtered.

Prefer glass models , others are made of polycarbonate. Particularly useful, some say it is time to change the cartridge but know that most cartridges have a shelf life of about a month. You can find these great pitchers in your normal surface.

Water filter on tap: the most convenient

This device is a bit more expensive than a carafe but it is less restrictive since it attaches directly to the neck of the faucet . The water is filtered as it exits.

That's why it makes sense to invest in a system with a filter that will pause when you do not need purified water to rinse dishes or doing housework for example. Useless indeed wasting your cartridges water filter should be changed every two to six months depending on the manufacturer. You will find this type of product in supermarkets and in health food stores and organic.

Osmosis: the most sophisticated water fitlres

Sold in craft stores, this type of water filter to be connected to a separate faucet removes chlorine, filter almost all nitrates, pesticides and lead, and most drug residues.

Two caveats, however: its cost remains high and above this system has nothing very green . 3-4 liters are usually needed to obtain one liter of clean water and pure.

Cartridges: attention to price

Important issues to consider when purchasing: the cost and durability of the cartridges. The saturation of the filter can lead to the development of bacteria, so it must be changed regularly .But their life is very variable from one brand to another.
