Water purification is the process of removing suspended solids and gases, contaminants, and undesirable chemicals from drinking water. Water purifiers enable the process of water purification. There are many variants of water purifiers such as offline water purifiers, UV water purifiers and RO water purifiers. However, purification using filters is not 100 percent effective. Purified water reduces the chance of water-borne diseases. The purification process decreases the concentration of particulate matter in water.
