water filter is a water filter used in water purification to remove impurities, dissolved solids, and contaminants through the process of pressurizing water with a semi-permeable membrane. It is widely used in drinking water purification for household, office, and industrial use.
How Does an RO Water Filter Work?
The purification process often involves more than one process:
Pre-Filtration (Sediment & Carbon Filters)
Removes excess impurities like dust, sand, and rust.
Activated carbon removes chlorine, odor, and organic impurities.
Reverse Osmosis (RO) Membrane
Water is pressured through a semi-permeable membrane.
Membrane rejects dissolved salts, heavy metals, bacteria, and viruses, but pure water gets through.
Post-Filtration (Carbon & UV/UF Treatment)
Additional carbon filtration removes impurities that improve the taste.
UV (Ultraviolet) or UF (Ultrafiltration) technology also clean the water further by killing bacteria.
Storage & Dispensing
Distilled water is kept in a reservoir and utilized when needed.
Advantages of RO Water Purifier
Eliminates dangerous impurities like lead, arsenic, fluoride, and bacteria.
Improves the taste and smell of water.
Provides pure drinking water, i.e., there is no way water-borne diseases can occur.
But RO purifiers also discard a minute amount of water during purification, so there are new models with water-saving technology like.
