Which filters in the air purifier can be cleaned? those that cannot be cleared.air purifier covid price

　　The most important thing about an air purifier is its "heart" and "lungs". The "heart" is what we call the motor. The "lungs" are what we call filters. And "lung" function is good or bad is whether it is clean. This also leads to the fact that air purifiers, unlike other home appliances, must be maintained after a period of use. This will keep the air purifier working at its best. The filters are generally divided into pre-filters, activated carbon meshes, HEPA meshes, cold catalyst meshes, etc. So which of these filters can be cleaned and those that cannot be cleaned?

　　1. Pre-filter: The main function is to remove large particles of dust, mold and animal hair. Perform primary filtration to control general pollution sources.

　　Can it be cleaned: Yes, because it belongs to the first layer of the air purifier filter, and its control is not particularly strict. But the cleaning time needs to be more frequent. Probably need to be cleaned every month. When cleaning, the dust on the surface should be cleaned first. Washing with water.

　　2. Activated carbon mesh: The honeycomb activated carbon filter is made of powdered activated carbon loaded on polyurethane foam, and its carbon content is about 35%-50%. With the efficient adsorption performance of activated carbon, it can remove volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and air pollutants.

　　Can it be cleaned: No, the activated carbon mesh does not need to be cleaned with water. Due to its manufacturing process and its own performance, it only needs to be exposed to the sun for a period of time to achieve automatic desorption and dust removal. Of course, some need to be replaced regularly. For details, please refer to the supplier and product manual.

　　3. HEPA net: HEPA is an internationally recognized best high-efficiency filter material. Initially, HEPA was used in nuclear energy research and protection, and now it is widely used in precision laboratories, pharmaceutical production, atomic research and surgical operations that require high cleanliness. . HEPA is interwoven with very fine organic fibers, with strong ability to capture particles, small pore size, large adsorption capacity, high purification efficiency, and water absorption, with a purification rate of 99.97% for 0.3 micron particles.

　　Can it be cleaned: No, as it is designed to capture particulate matter. The pore size of the filter screen needs to be strictly controlled. If cleaning is carried out, the pore size is wrong and the purification efficiency is reduced, it will not be worth the loss.

　　4. Cold catalyst network: The filtration principle of cold catalyst is mainly to decompose toxic and odorous harmful gases into harmless and odorless substances by catalytic reaction under normal temperature conditions, and change from simple physical adsorption to chemical adsorption, while adsorption Edge decomposition.

　　Can it be cleaned: It should act as a catalyst and cannot be consumed. So basically don't replace it. So naturally no cleaning is required.
