Water purifier products have become an indispensable part of people's lives. Many people like to install water purifiers directly during the home decoration process. Especially in the kitchen, the water purifier is an inevitable choice for people. But for many people, how to choose a water purifier product is a problem worthy of attention.

 

The principle of the water purifier is to achieve the effect of filtering harmful substances on the human body and purifying water quality through the water treatment of the terminal. The design of the water purifier is different depending on the water quality. China has a vast territory and a large difference in water quality. Generally speaking, the water quality in the north is hard and there are many impurities. The water purifier or water softener with ion exchange resin filter should be purchased. The water quality in the south is soft, the heavy metal and secondary pollution are serious, and the water quality requirements are met. High-grade households can purchase reverse osmosis pure water machine. If the local water quality is good, you can choose ultra-filter.

 

The main water purification materials used in water purifier products are polypropylene cotton, activated carbon, UDF, ultrafiltration membrane, reverse osmosis membrane, infrared mineralization sphere, etc. Different water purification materials will produce different water purification effects. Consumers can match different filter elements to different needs. The advantage is that the price is cheap, the filtration precision is high, and the disadvantage is that the filter element has a short life and a small amount of water, and is only suitable for drinking.

 

When purchasing a water purifier product, the user may not be able to clearly indicate the water quality. This requires that the sales service of the water purifier brand should be comprehensively planned according to various factors such as water quality, waterway, and room size. In the after-sales service, the replacement period of the product filter element must also be guaranteed.

 

The filter element of the water purifier should be replaced regularly to ensure that the water can be filtered clean. The life of SC-PP cotton is usually 3-6 months, the granular activated carbon filter is 6-9 months, the mesh compressed carbon filter (UF) is 9-12 months, and the reverse osmosis (RO) membrane is 36 months. The post-activated activated carbon (T33) is from September to December. If it is not replaced within the time limit, it may breed bacteria and cause secondary pollution of water quality.
