Water purifiers

Water purifiers are devices that are used to make water cleaner and more pure. A water purifier takes impurities from water through a physical barrier, a physical process, or a chemical method. The physical barrier is often a sheet of material that has permeable or semi-permeable properties allowing water to pass through but keeping impurities on the other side of the barrier out. Chemical processes often include boiling or dissolving. Biological processes include the use of live organisms for instance bacteria, viruses, cysts and other microorganisms. Other methods include electricity, solar power and heat.

Biological solutions work well for many applications in both homes and industries. Many pathogens cannot survive in de-mineralized water, so the goal of many water purifiers is to render the water as clean as possible. One way to accomplish this is through the use of a reverse osmosis step. Reverse osmosis is where the solution is passed over a semi-permeable membrane. The semi-permeable membrane is porous and has a fine chemical gradient that allows only hydrogen and heavier chemicals through while letting in lighter ones such as oxygen and carbon dioxide.

There are two main types of filters used today. Both are effective and are available in various price ranges. In addition some are more efficient than others depending on the type of contaminants being treated. Water purifiers that use a carbon filtration method are usually the most cost effective. They also are the only type that can remove viruses, fungi, and other pathogens that are too small to pass through a standard filter or a reverse osmosis system.
