The term "water purifier" refers to a portable device that cleans water of pathogens, bacteria, toxic chemicals, and other dissolved materials. Water purifiers are self-contained machines to make untreated water from lakes, rivers, and wells drinkable. The water is made drinkable by employing water purifiers to remove any hazardous bacteria and tiny Cryptosporidium parasites that could cause diarrhea. Generally speaking, homes and businesses are where you'll find water purifiers. Additionally, they are utilized by military personnel, campers, hikers, those who live in dry climates and don't have access to enough clean water, and people who travel in disaster-prone areas. Point-of-use water treatment systems and water purifiers both have similar names.

Two basic categories of water purifying systems make up residential water purifiers. A point-of-entry or whole-house filter system is installed at the point where water enters houses. The other type, called point-of-use systems, is put at the location where water is consumed. The water is completely purified when point-of-entry and point-of-use filter systems are installed, including pathogen removal and softening. The purification system uses filter media to remove impurities from raw water, producing better-quality purified water that is safe for both general and specialized purposes. These purifiers come in various technological configurations, including reverse osmosis, ultraviolet light, and gravity-based filtration.
