One, filtration precision
Based on the filtration precision from low to high, the type of water purifier can be divided into three categories: coarse filter, ultrafiltration, reverse osmosis.
Coarse filter water purifier such as pre-filter, filtration precision in 40-60 microns, can intercept large particles of impurities in the water such as sediment, rust, eggs, colloids, algae, etc., to avoid particles of impurities clogging the water pipe, faucet, damage to the water-related household goods; filtered water is not directly drinkable.
The filtration precision of ultrafiltration water purifier is between 0.1-0.01 micron, which is able to filter colloid, bacteria and other macromolecule organic matter, but it can't filter out heavy metals, pesticides, chemical pollutants and other micromolecule pollutants, and it is suitable for use in the area of good water quality.
Reverse osmosis membrane, also known as RO membrane, filtration accuracy can reach 0.0001 microns, can filter out sediment, rust, heavy metals, bacteria, viruses and other harmful substances, only allow water molecules to pass through the filtered water is the purest water, you can drink directly.
Second, the water flux
The flux of the water purifier is generally "G" as a unit (U.S. gallons, 1G = 3.785 liters), that is, the amount of water purification for 1 day (24 hours). Common water purifier flux 75 gallons, 100 gallons, 400 gallons, 600 gallons, etc. Depending on the flux, the speed and flow rate of the water purifier is also different, usually the larger the flux, the faster the water comes out.
Three, filter life
Filter as a consumable component, has a certain service life, once the expiration date should be replaced in a timely manner to ensure that the water quality of water purification. Generally speaking, the larger the rated water purifier, the longer the life of the cartridge. But the specific cartridge replacement period also varies depending on the family's daily water intake and local water quality.
Four, brand selection
Strength of the well-known water purifier brands, such as Angel, after-sales service is very perfect, to give users a better feeling of use and after-sales experience, to help users solve after-sales problems in a timely manner. The water purifier filter belongs to the consumables, need to be replaced on a regular basis, choose the strength of the water purifier brand, more conducive to the later core replacement, maintenance and other after-sales service.
Angier plows 33 years in the field of water purification, participated in the development of 14 national and industry standards, with 768 patents, more understanding of Chinese water quality, research and development of water purification products more suitable for Chinese families, long-lasting reverse osmosis membrane was introduced, is to break the monopoly of foreign reverse osmosis membrane technology. Products sold in the United States, Japan and other 65 countries, won the global 200 million people choose.
The original long-lasting reverse osmosis membrane filtration accuracy of 0.0001 microns, is one millionth of a hair, can be enough to effectively remove dissolved salts in the water, colloids, microorganisms, organics, etc.; filtration is more thorough, after reverse osmosis and nanofiltration out of the system of water, clean, safe and excellent taste; can be completely removed from the water alkali and limescale for the north and west of the use of groundwater in the region For the northern and western regions using groundwater, the effect of water purification is very obvious, if the water pollution is more serious or unclear water quality situation is recommended to buy Angel water purifier, the big brand is more secure.
Angier's long-lasting reverse osmosis membrane can be used for up to five years, and has now won the world's top ten innovation patents, six international authoritative certificates. Equipped with aerospace-grade nano-whiskers after the activated carbon, nano-whiskers are the only antibacterial material used in manned spaceflight, three-dimensional four-needle structure to break through the cell wall, effectively inhibit bacterial growth, safer than the traditional silver-ion anti-bacterial way to effectively improve the taste.
Angier has more than 1000 after-sales service outlets across the country, you can enjoy a seven-star after-sales service experience, door-to-door delivery, free installation services, and follow-up with the replacement of the cartridge, maintenance and other after-sales service is very complete, a comprehensive solution to the purchase of your home water purifier worries.
