Should the water purifier be installed? At present, most household water purifiers on the market are composite water purifiers, which are mainly made of pp cotton, activated carbon or other composite adsorption materials and membrane materials in series. Activated carbon can efficiently adsorb chemicals in water. As long as the membrane material reaches ultrafiltration, that is, the membrane aperture is 1-10 nm, it can effectively intercept pathogenic microorganisms. Therefore, activated carbon and membrane composite water purifier can further optimize water quality. The composite water purifier has more advantages, which can absorb and intercept microorganisms in the water and consume residual chlorine and other chemicals, but it also has certain disadvantages. It only plays the role of physical filtration for microorganisms and does not completely kill them. With the extension of the service time of the water purifier, or the occurrence of problems such as unscientific use methods, microorganisms may also proliferate, threatening health. Therefore, regular maintenance is very important when using a composite water purifier. It is recommended to choose a compact structure of activated carbon + ultra / nano filtration composite water purifier, which should be used scientifically and maintained regularly Different colors available,any colors and logos can be customized 5S quick filter replacement Easy to assemble and replace internal filter , you can solve it at home First Step: Twist down the filter Second Step:Take out the filter counter clockwise
