Many people do not know the function and replacement cycle of the basic filter of the water purifier. In fact, even the best filter cartridges need to be replaced. If the filter element is used for a long time, it will absorb a lot of dirt. If it is not replaced in time, it will have a great impact on the water quality. Said so much below to introduce the basic filter for everyone.
Basic filter is generally divided into five levels
* Grade: High precision polypropylene PP cotton filter. The pore size is dense and uniform, and the filtration efficiency is up to 99%, which can effectively filter out sediment, rust, impurities and suspended matter in water. (normal replacement cycle 3-6 months)
Second stage: UDF granular activated carbon filter. Granular activated carbon filter element for adsorbing organic matter, chemical pesticides, residual chlorine, heterochromatic odor, etc. in water; normal replacement cycle 3-6 months)
The third stage: CTO compressed activated carbon filter. CTO compressed activated carbon, also known as bulk activated carbon, is used to remove residual chlorine, chemical pesticides, heterochromatic, odor, and filter fine impurities. In the third stage of the pure water machine to protect the RO membrane, the service period is 3-6 months.
Fourth stage: RO reverse osmosis membrane. It has been developed by American aerospace technology for many years and is currently produced in only a few countries such as the United States, South Korea, and Japan. RO membrane pore size is 0.0001 micron (equivalent to 1/6000 of E. coli size), which can trap bacteria, viruses, organic matter, colloids, pesticides, heavy metals, most of the salts in water, and the treated water is sweet and delicious. Master the technical content of all water-making technologies. The period of use is 1-3 years.
a, the RO pore size is one tenth of a nanometer, which is equivalent to the diameter of water molecules;
b, the diameter of the bacteria is more than 4000 times the RO pore size;
c, the diameter of the virus is 200-4000 times the RO pore size;
d, the pore size of organic pollutants such as pesticides and insecticidal brakes is about 10-400 times that of the RO pore size;
e, heavy metal ions, chemicals have a diameter of about 10 times the RO pore size.
The fifth level: the rear coconut shell activated carbon small T33. Inhibits bacterial regeneration. It is used to remove odor and regulate the taste of water. Replace it from June to December.
