As people pay more and more attention to water quality, water purifiers have become a tool for purifying water quality. However, with the intensification of market competition, the product quality of the water purifier market is also uneven. What are the erroneous zones for purchasing water purifiers? Let's take a look.

Misunderstanding 1: The more product filter, the better

Some manufacturers promote their own product filter filter, but in fact the filter is not as good as possible. Some clean water does not move on four or five filter elements, but all use simple filter materials. The filtering effect is not as good as a high-performance composite filter element. Experts remind consumers that the last filtration component of drinking water should use disposable filters as much as possible to avoid secondary pollution.

Misunderstanding 2: Imported products must be better than domestic ones

Some consumers believe that imported products are certainly better than domestic ones. Experts said that tap water in developed countries is of good quality and can be consumed directly. Their domestic water purifiers are generally used to solve the secondary pollution that water pipes may form. Therefore, the purification process of imported household water purifiers is usually relatively simple, and is generally "pre-filter + activated carbon." For those countries where tap water can reach the standard of direct drinking, such a water purification process is already sufficient. However, the water quality in our country is relatively complex and it is impossible to purify completely by a single water purification process. From the aspect of water purification technology, the domestic water purifier that combines filter elements is more suitable for China's water quality.

Misunderstanding 3: The longer filter life, the better

Some water purifiers on the market claim that filter cartridges can be replaced within 3 to 5 years. Experts say that not replacing them all the year may mean that the filtration accuracy is greatly reduced. This will not only result in poor purification but also cause secondary pollution.

Misunderstanding 4: Put on a water filter to sit back and relax

Many people think that installing a water purifier can be a good thing, but it is not. Take a five-stage filtration reverse osmosis water purifier as an example, the general PP cotton needs to be replaced once in two months, the life cycle of the activated carbon filter is 3-6 months, the life of the ultrafiltration filter is 24 months, and the reverse osmosis filter can be used 36 months. Experts advise consumers that water purifiers need to change filter elements in order to ensure the filtering effect, otherwise the filter element may become a source of pollution. The replacement frequency of the filter element depends on the actual water pollution situation. It is found that the water flow of the water purifier is smaller than before, and it is necessary to consider replacing the filter element.
