The Core Role of The Cartridge in The Water Purifier
(A) Functional principles of different types of cartridges
Common filter elements in water purifiers include PP cotton cartridge, activated carbon cartridge, ultrafiltration membrane cartridge, reverse osmosis membrane cartridge, etc. PP cotton cartridge is mainly used to intercept large particles of impurities, such as sand, rust, etc., which is like a primary guard to protect the subsequent cartridge from the damage of these large particles. Activated carbon cartridge uses its porous structure to adsorb residual chlorine, odor, organic matter, etc., to improve the taste of water. Ultra-filtration membrane cartridges are able to filter out bacteria, colloids, macromolecular organics and other small particles, while reverse osmosis membrane cartridges are more precise and can remove almost all impurities, heavy metal ions and dissolved salts from water, which is the key to producing pure water. These different types of cartridges cooperate with each other to form a layer-by-layer filtration protection system.

(ii) The impact of the quality of the cartridge on the effect of water purification
The quality of the filter element directly determines the water purification effect of the water purifier. High-quality cartridges can more effectively remove pollutants in the water to ensure that the water quality meets or even exceeds the safety and health standards. For example, a high-quality reverse osmosis membrane cartridge with a high desalination rate can stably produce high-quality pure water. On the contrary, low-quality cartridges may be incomplete filtration, easy to break and other problems, not only can not guarantee the safety of drinking water, but also may lead to damage to other internal components of the water purifier, shortening the service life of the entire water purifier.
