With the physical and mental health of drinking water becoming the focus of attention, the water purifier has become a part of household consumers who pursue perfect physical and mental health and quality. However, manufacturers often cheat customers to buy more expensive and most profitable products, but they do not strongly recommend them to customers what they really need. Therefore, the website compiles a map of the filter layer expertise of water purifiers for everyone, so that everyone can be more comfortable in selecting.
First stage: PP cotton filter element
PP cotton filter element, also known as polypropylene melt blown filter element, has a diameter of 5 microns, and is characterized by small size, large filtering area, high precision, easy replacement, etc. In addition, the PP cotton filter element is a double-layer type, which has a large amount of pollutants and is resistant to acid, alkali, organic chemical aqueous solution, etc., and has excellent organic chemical reliability. The PP cotton filter element can remove rust, fine sand, colloidal solution, suspended solids and other large particle residues in the water, and the replacement time is 3-6 months.
Second stage: activated carbon particle filter element
The water flows from bottom to top, so the contact time between water and activated carbon particle layer is long and the total area is wide, so the activated carbon filter element can fully play the role of chlorine removal, odor removal, odor removal, etc. Activated carbon particles have a strong absorption capacity, which can remove the organic chemical environmental pollution caused by pesticide, fertilizer residue, solvent and other industrial production in water, and can also absorb the organic compounds, permanganate index and other chemical substances in water, and have a strong role in removing odor. The actual replacement time is 6-12 months.
Level III: high-density polypropylene filter element
The diameter of the high-density polypropylene filter element is 1 μ m, which is more detailed than the first level PP cotton filter element. It can further filter out the particulate residue, permanganate index, and odor in the water, so as to relieve the pressure in the operation of the filter element after the event. The actual replacement time is 6-12 months.
Level IV: ROro reverse osmosis membrane filter element
The filtration precision of ROro reverse osmosis membrane filter element is up to 0.0001 μ m. Chlorite, bacteria, inorganic compounds, heavy metal ions, etc. in the water can be removed, and only water and some favorable mineral positive ions can be preserved. The replacement time is from 1 to 3 years.
Level 5: Taste factor filter element
The taste factor filter element uses non-toxic and odorless shell activated carbon and coal based activated carbon as the main actors, which can inhibit the reproduction of bacteria and improve the taste of water. The replacement time is about one year.
There are only some types of RO RO water purifier filter elements above, but some water purifiers use composite filter elements, so the proportional order will be reduced to a certain extent. Some water purifiers use other types of filter elements at the third level, but most RO RO water purifiers have such filter elements above. It is expected that the partners who have seen the above content will be able to purchase water purifiers that are in line with their own feelings.
