First of all, no matter what kind of water filter cartridge is used in the water purifier, most of the water filter cartridge has two functions: filtering or adsorption. Common PP cotton filter cartridges and ultrafiltration filter cartridges are representative of filtering type filter cartridges.They rely on their own filtering accuracy to filter and trap pollutants of different sizes. However, the process of these materials retaining pollutants is also a process of their own being gradually polluted. Therefore, after a certain period of time, the filter cartridge will deposit harmful substances such as microorganisms and bacteria, so it must be replaced regularly.
The filter cartridge represented by activated carbon is a representative of the adsorption type water filter cartridge.These filter materials rely on their strong contact area, which can effectively absorb organic pollutants, residual chlorine and disinfection by-products in water sources. However, they are similar to the filtering type.
With the accumulation of these pollutants on the surface of activated carbon, the adsorption efficiency of the adsorption filter cartridge will gradually decrease.What’s more important is that these filter cartridges that adsorb a large amount of pollutants will become a breeding ground for microorganisms.If the activated carbon filter cartridge cannot be replaced for a long time, microorganisms will multiply in the water purifier.They will pollute the entire filtration system over time，and will emit an unpleasant smell during the decomposition process, which will greatly affect the quality and taste of the effluent of the water purifier.
Huatan Filtration,a leading manufacturer with many years of experience in producing high-quality carbon block cartridges and water purifiers in China. We believe that even the best brand filter cartridges are used to purify water and adsorb impurities, pollutants and bacteria.If the water filter is used for more than the normal use time, it will definitely breed more bacteria. If you do not replace the filter material according to the normal cycle of the filter cartridge, That’s not as safe as drinking tap water directly!
