Some knowledge of air purifiers

　　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.

　　Because there are various technologies and materials in the air purifier, it can provide customers with clean and safe gas. Common air filtration technologies include: absorption technology, negative (positive) ion technology, catalytic reaction technology, nano-photocatalyst, superstructure photoacidification technology, HEPA high-efficiency filtration technology, electrostatic induction dust collection technology, etc.; the key to raw material technology is: photocatalyst removal technology formaldehyde, activated carbon, man-made fibers, HEAP high-efficiency raw materials, air anion generator, etc. The current air purifiers are mostly composite, that is, a variety of purification treatment technologies and raw materials are selected.

　　The air purifier can filter and dissolve the indoor formaldehyde in the room, thereby significantly reducing the amount of indoor formaldehyde in the room. After the air purifier is applied to the house of the newly renovated house, it can be seen from the LCD screen of the air purifier. The amount of indoor formaldehyde is significantly reduced, so that the body is less exposed to formaldehyde hazards. In addition, the air purifier also has other functions.

　　The filter device in the air purifier is a key component, and it is a component that removes particles. Depending on the filter device, it can be divided into different types. For example, high-efficiency particulate gas (HEPA) filter devices can filter out particles above 0.3μm, but only allow the gas to pass through, and all allergens and smoke in the gas can be filtered out.
