Is the tap water filter useful?
1. Is the tap water filter useful? Different types of tap water filters have different functions. However, in principle, tap water filters are useful, and different types of filters have different effects.
2. Some tap water filters mainly filter larger impurities, and some use reverse osmosis and ultrafiltration membrane separation technology to make tap water drinkable. The ultrafiltration membrane accuracy of some tap water filters can reach the level of 0.01μm. There are all kinds of bacteria and viruses in the water. The diameter of bacteria and viruses that can survive in water is 0.02 microns. Therefore, the pore size of the ultrafiltration membrane of the tap water filter is smaller than the pore size of bacteria, and can filter out 99.99% of bacteria and viruses.
3. The tap water filter can also retain the mineral elements in the water, but it is limited to the ultrafiltration tap water filter. RO membrane filtration is used for reverse osmosis, with an accuracy of 0.0001μm, which can filter all substances in the water except water molecules. The precision of the ultrafiltration membrane is accurate to the critical point, and only trace elements are retained while filtering bacteria and viruses.
