Although the water purifier has many benefits, it will also have various problems when used for a long time. Then the water purifier kept ringing. What is the reason? Let's have a look.

First, the water purifier keeps ringing. What is the reason?

Mostly because of the maintenance system of the water purifier. Remove the water purifier first, and then check whether the filter element leaks. If yes, wipe the leaking place with a dry cloth, and then install the filter element of the water purifier according to the instructions. There is a lot of noise, so we should check its water tank first to see if there is anything wrong with the water level valve of the water tank. In this case, we must readjust the water level valve.

Second, how to buy a water purifier

1, check the qualification certification of water purification products. Main water-related approval documents, water quality test reports and trademark licenses. At present, many small manufacturers in the market do not have these ratings, and this technology can eliminate their unqualified brands.

2. It is necessary to buy a water purifier with a pre-filter. Because the pre-filtration system is used as a coarse filter, it can directly remove large particles of impurities and rust, thus ensuring the filter element and prolonging the service life of the system.

3. Pay attention to the flow and water treatment capacity of the water purifier. Water purifiers are generally divided into large-flow and small-flow water purifiers. Therefore, consumers should choose a suitable water purifier according to their own needs when purchasing a water purifier.

4. Check the life and price of the filter element of the water purifier. Because the filter element of the water purifier will be replaced regularly, it will inevitably lead to some expenses, so consumers should choose the appropriate water purifier model according to their own economic situation.

Please check the product description before buying the water purifier. Some families, such as babies, should not only choose high-quality milk powder, but also the water for milk powder. In this case, we must use a water purifier to remove harmful metal ions from water.
