At present, there are many kinds of water purifiers on the market. Whether in Gome, Suning or terminal stores in national chain stores, there are water purifiers sold in building materials and household appliances wholesale markets, and the styles are diverse, which dazzles you! How to choose a suitable water purifier requires you to have a good understanding of the functional types of the lower water purifier; Today, Xiaobian will share with you the common classifications of water purifiers in the market:
1. Prefilter
Prefilter, also known as primary preprocessor; This kind of water purifier commonly includes PP cotton filter, activated carbon filter and filter with stainless steel mesh; The filtering accuracy of pre filter is generally between 5 microns and 50 microns; It mainly filters the large particles visible to the naked eye in the water, such as rust, sediment, colloid, etc;
2. Ultrafiltration water purifier
As the name suggests, ultrafiltration water purifier mainly uses ultrafiltration membrane as the core filter material; The dense micropores on the surface of the ultrafiltration membrane are physically screened to filter out the rust, particles, bacteria, some viruses, colloids, some organic substances and other harmful substances in the water, keep the pH value of the effluent unchanged, and retain the dissolved oxygen in the water and trace minerals required by the human body; Ultrafiltration membrane water purifier provides drinking water in line with the concept of safety and health;
The reverse osmosis membrane is mainly used as the core filter material, and the filtration accuracy is as high as 0.1 nm; It is the model with the highest precision among all water purifiers; The water filtered by this type of machine is generally defined as pure water, so it is called pure water machine; Any pure water machine needs to be driven by booster pump and needs to be powered on. The quality of the pure water machine mainly depends on the quality of all membranes and filter elements of the model itself; At present, the most famous reverse osmosis membranes on the market are American Dow membrane, funuotai membrane, South Korean Shihan membrane, etc; Good membranes can be used normally for 2-3 years. Poor and inferior membranes are often blocked in less than half a year.
4. Double membrane double water machine
At present, the trend products in the water purifier industry have not been popularized, but they have great potential. This kind of product perfectly combines the ultrafiltration water purifier and RO pure water machine, one machine with double membranes and double effluent. Generally speaking, a machine can produce both ultrafiltration mineral water and purified water; For a family member with inconsistent drinking habits, the double membrane double water machine meets their needs well. The double membrane double water machine has many advantages in function, but the cost is not low.
5. Water softener
Due to the limitation of its function, the water softener is mainly used in the areas with hard water quality in the north. It mainly uses softening resin as the medium to separate calcium and magnesium ions in the water, so as to reduce the water hardness; At present, it is used in beauty salons or installed in front of domestic water heaters to soften the water, so as to protect and prolong the service life of water heaters; Use the water softened by the water softener to wash dishes and clothes, which is cleaner and more shiny!
6. Functional water machine, frequency spectrum water machine and electrolytic water machine
This type of machine is specific and deceptive, exaggerating the function of the product, and threatening that the water filtered by the machine can treat all kinds of senile diseases and children's diseases; This kind of products are often sold to their relatives and friends through the sales mode and direct sales personnel.
