Is the water purifier product really able to provide healthy drinking water? Here, the UDF filter cartridge manufacturer reminds you that in the absence of instruments, we can check the water quality purified by the household water purifier through the following methods.

1. First of all, we can fill a bright glass with a cup of water filtered through a household water purifier, and then carefully check whether there are suspended delicate substances in the water in the direction of sufficient light. If there is, it means that the filtration effect of the water purifier is not good. If not, then cover the quilt and let it stand for three hours, and then check whether there is sediment at the bottom of the cup, if there is, it means that the suspended impurities in the water are severely exceeded, and the filtration effect of the water purifier is unqualified.

2. Use the water filtered through the water purifier to make tea, leave it for a night, and then come to investigate whether the tea turns black the next day? If the tea turns black, it means that the iron and manganese content in the water is severe and overrun, and the water purifier is unqualified for the metal ion filtration effect.

3. Use a glass to pick up a glass of water directly at the faucet, and then smell it with your nose, is there a taste of bleaching powder (chlorine)? If you can smell the taste of bleaching powder (chlorine), it means that the residual chlorine in the tap water is overrun! Then use the cup to catch a cup of water filtered by the water purifier, check it with the same method, if it is still smelly, it means that the water purifier has a bad effect of chlorine removal.

4. Check whether there is a significant layer of scale on the inner wall of the water dispenser or kettle at home, if there is, it also means that the hardness of the local water quality is too high, and the calcium and magnesium ion content is high. Then use a clean water dispenser or kettle to boil the purified water of the household water purifier, and check whether the inner wall of the water dispenser or kettle is still limescale after continuous use for about a week.
