How to maintain the air filter of the purifier
There are three common types of purifier air filters: pre-filter (coarse air filter), deodorization filter (activated carbon filter), and high-efficiency filter. Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde, etc.) , Bacteria, allergens, etc.), products that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.
There are many different technologies and media in the air purifier, which enable it to provide users with clean and safe air. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure light mineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Synthetic fiber, HEPA high-efficiency material, negative ion generator, etc. Most of the existing air purifiers are of composite type, that is, multiple purification technologies and material media are used at the same time.
Like water purifiers, air purifiers need to be cleaned regularly, and some need to replace filters, filters, etc. to maintain their purification effect. The maintenance and maintenance of air purifiers depends on different brands and types of air purifiers.
Filter type purifier:
1. The front filter (usually the back cover of the case) has been used for a long time, and some dust will be collected, which will affect the air intake and the effect of air purification. Therefore, you need to use a vacuum cleaner to suck away the dust, or use a rag to clean it, or even wash it with water.
2. Filters, some filters need to be exposed to the sun regularly, so that the purification efficiency can be better maintained, such as activated carbon filters.
3. Deodorizing filter, the deodorizing filter of a few brands of air purifiers, in order to achieve the technical level of washing, it can be washed with water, that is, to maintain the purification efficiency and extend the cycle of filter replacement.
4. Ionizers are generally built-in and do not need to be cleaned. Better ionizers have higher working efficiency.
The dust filter or dust collecting plate in the air purifier should be cleaned frequently, usually once a week, and the foam or the plate should be washed and dried with soap liquid before use to keep the airflow unobstructed and hygienic. When there is a lot of dust on the fan and electrode, it must be cleaned up, and it is generally maintained once every six months.
