Tap water can still contain some chemicals and other pollutants that may make it unsafe for drinking. This requires you to fit water filters to improve the quality of water.

Choosing a filter can be confusing because of the many different types of filters that are available for home use. Some of them are easy to install, some are easy to look after, while there are filters which require some care and maintenance. The filtration of water goes through the physical processes of sedimentation, filtration, and distillation. Filters also use biological filters like slow sand filters and activated carbon. Some use flocculation and chlorination which are chemical processes. Others use ultraviolet light or reverse osmosis to give you clean filtered water.

Water filters can use all the methods of filtration, physical, biological, chemical and others to provide you the required output of safe drinking water. Most water filters use carbon filters to remove large particles from your water supply and will trap silt and sediment. The use of these filters also reduces odor and improves the taste. There is a significant reduction of chlorine that is used by most municipalities to treat water. These carbon filters use activated carbon or charcoal that has been treated with oxygen so that tiny pores open up in between the atoms of carbon. This activated carbon is efficient at removing pollutants.

Reverse osmosis filters remove all hazardous contaminants and make the water free from odor. In this process, water is allowed to pass through thin membranes under pressure and removes all solids, dissolved liquids, and even arsenic and lead. Most reverse osmosis filters also have other carbon filters and water in them passes through two or three stages before it is allowed for consumption.

The electrolysis process is used in some alkaline filters and water ionizers. Water passes over plates that are electrically charged. This separates the water into two streams one that is acidic and the other that is alkaline. So you can get water that has very little acidity while also being softer, and therefore more suitable for the hair and the skin.

One of the latest technologies in use for water filters is the use of ultraviolet light. This light destroys all bacteria that can be dangerous to health. The fact that these filters use no chemicals or heat, makes them environmentally friendly. Some filters use infrared light to make the water softer. They use both light and heat to give the water a negative charge.

Reverse osmosis water filters remove all contaminants, minerals, and particles. They can be expensive to install and maintain. They also have a low flow rate and do cause some wastage of water. The removal of minerals that are essential in water may require separate devices to add back the required minerals. The best water filter for a home is better decided on the quality of the water that is being supplied to a home. Test your water, find water filters that can remove any detected impurities and those that are low in cost, easy to install and not too difficult to maintain.
