What is the difference between Annette's front filter and water purifier? All of them purify tap water, but these two are not one thing. The front filter is installed behind the water meter. the tap water of the household will be filtered again to remove the particles and impurities. in addition to drinking water filtration, it also protects water-related appliances such as water purifiers, washing machines, water heaters and faucets, however, the water after filtration cannot be drunk directly. it should be boiled and drunk again. The water purifier is finely filtered, and the filtered water can be consumed directly. However, the pressure loss is large, so it can only be installed at the end and only has a protective effect on drinking water. So, the two are the best together.
