The common water purifiers on the market today are: pre-filter, ultra-filtration water purifier, reverse osmosis water purifier, centralized water purifier.
Pre-filter water purifier
It is installed on the inlet pipe or inlet main valve at the back end of the water meter, which can simply filter the water of the whole house, such as silt, rust, and other impurities without plugging in and consumables, but the filtered water can not be directly consumed.
Suggestion: If there are problems such as poor water quality, excessive limescale, aging community pipelines, etc., you need to install a pre-filter to protect the normal use of water purifiers and household water-related appliances.
Ultra-filtration water purifier
Ultra-filtration water purifier, the filtration accuracy of about 0.001-0.1μm, can filter out impurities in the water, rust, some bacteria, viruses, colloids and so on. It does not need to be plugged in and has consumables, but heavy metal ions and viruses with a diameter of less than 0.1μm cannot be filtered and cannot be drunk directly.
Recommendation: ultrafiltration water purifier water can not be directly drinkable, filtration accuracy is not as good as reverse osmosis water purifier, but the price is cheap.
Reverse osmosis water purifier
In all household water purifiers, reverse osmosis water purifier has the highest filtration precision, filtration precision of 0.0001μm, can filter rust, sediment, bacteria, viruses, heavy metal colloids, etc., the water can be directly drinkable.
Suggestion: it can filter bacteria and viruses and drink directly to meet the standard of safe drinking water. It is an "anti-toxin, anti-bacteria" water purifier that everyone can buy.
Central water purifier
It has multiple functions to cover the daily drinking water of the whole house with consumables, suitable for schools, beauty parlors, villas, single-family houses and other scenarios with high cost and good effect.
Recommendation: for families that need water purification for the whole house, as well as families that meet the installation space, you can consider installing it.
Piped water dispenser
If there are old people and children at home, it is recommended that families who often make tea and drink milk powder purchase. Piped water dispensers have two to three levels of temperature control, so you don't have to wait and can produce hot or warm water at the touch of a button.
Suggestion: Piped water dispensers can solve the problem of domestic drinking water, replacing water dispensers and electric kettles. There are two kinds of hot and cold, partners can buy according to their own preferences and needs.
Water softener
Softener mainly through the ion exchange resin to remove calcium and magnesium ions in the water to reduce water hardness. The other is different from the chemical ion exchange method of physical water softening method. It is the use of high-energy polymerization ball in the water of calcium and magnesium ions wrapped into crystals, so that they do not scale in the water.
