Water filters come in a variety of types and styles. One factor that differentiates them from one another is the kind of water filtration method they use. Different water filtration technologies are- Distillation, Carbon Absorption, Microporous Basic Filtration, Reverse Osmosis and Ultraviolet Radiations.

Distillation is an ancient method in which you heat water until it vaporizes. As the water vaporizes, bacteria, minerals and most of the other substances are left behind. The steam cools and condenses into relatively pure water. This is how we get pure water through distillation method.

It lacks oxygen and minerals and has a flat taste. Organics such as herbicides and pesticides with boiling points lower than that of water cannot be removed efficiently and can actually become concentrated in the product water. One more disadvantage of using it is the large amount of energy and water used by this filtration system.

Carbon filters are very effective in cleaning water. When water flows through carbon filters, contaminants adsorb or stick to the surfaces of the carbon particles and the water is passed through it. Activated carbon filters are reported to be the best method available for removing specific organic chemicals, including some pesticide residues. Studies have also shown that GAC (granular activated carbon) adsorption is an effective method for radon removal. Carbon water filter devices are available in several sizes and designs. They are relatively inexpensive to replace and ensure a continued high standard of filtration.

In microporous filtration system there are three types of filtration layers: depth, screen and surface. All three serve very different functions. Depth filters are usually used as pre-filters because they are an economical way to remove 98% of suspended solids and protect elements downstream from fouling or clogging. Surface filters remove 99.99% of suspended solids and may be used as either pre-filters or clarifying filters. Microporous membrane (screen) filters are placed at the last possible point in a system to remove the outstanding traces of resin fragments, carbon fines, colloidal particles and microorganisms.

Reverse Osmosis filters are widely used to provide purified water. The reverse osmosis process basically draws water through an extremely fine membrane. The membrane acts like an exceptionally fine filter to create drinkable water from salty or contaminated water.

RO filters work on the concept of osmotic pressure. A lot of pressure is required in this process. For most of the models, a strong pump is used to supply needed fluid pressure. But as a result they provide extremely pure water. These filters waste a lot of water.

Ultraviolet radiations are very effective in killing germs and hence makes water germ free. Mercury low pressure lamp generating 254 nm UV light is an efficient way of doing this. All the germs and microorganisms are either killed or inactivated by this process, giving you clean and clear water.
