In recent years, the degree of air pollution has become more and more hepa air filter for home economic development, especially in winter, many families have begun to pay attention to the health of the air, so air purifiers have gradually entered many household appliances, and the market has also set up a surge of air purifiers, so You really know about air purifiers and we analyze their pros and cons.

1. PM2.5 screening program

PM2.5 is filtered by High Efficiency Air Screening Program (HEPA). The HEPA screener consists of a continuous stack of subfiber glass membranes folded back and forth to form a wavy space that maintains and supports the borders of the screener. Strong particle capture ability, small pore size, large adsorption capacity, high purification efficiency, and water absorption, for 0.3 micron particles, the purification rate is 99.97%. That is, only 3 out of every 10,000 particles can penetrate the HEPA membrane. HEPA is internationally recognized as the best high-efficiency filter material. HEPA was originally used in nuclear energy research and protection, and is widely used in precision laboratories, pharmaceutical production, atomic research and surgery that require high cleanliness.

2. Removes odors and volatile organic compounds

Catalyst Filtration: Cold catalyst is a new type of air purification material, which can catalyze oxidation reaction under normal temperature environment, decompose various harmful and odorous gases into harmless and odorless substances under normal temperature and pressure. It cannot directly participate in the market reaction, and the cold catalyst does not change or lose after the reaction, and it plays an important role effectively in the long term.

Activated carbon filtration: Activated carbon has good aerodynamic properties, small bulk density, large surface area, high adsorption efficiency, low wind resistance and long service life. The principle is based on the developed pore structure and surface area of ​​activated carbon. In addition, the present invention can have a greater degree of contact with ambient air, and can passively adsorb pollutants into its pores, so the larger the surface of the activated carbon, the more developed the pore structure and the stronger the adsorption capacity. Theoretical research shows that the larger the molecular weight of harmful substances, the easier the activated carbon is to adsorb.

3. Antibacterial and sterilization

Contact reaction sterilization: more than 99% of harmful bacteria are unicellular; and unicellular bacteria must rely on the oxidation of oxygen metabolism enzymes to breathe. The oxidation process of oxygen-metabolizing enzymes is the process of capturing electrons from neutral particles. When the nano-silver particles are close to the bacteria, they will be adsorbed on the surface of the bacteria and enter the interior of the bacteria through Coulomb gravity. The bacteria's oxygen-metabolizing enzymes steal an electron from the silver nanoparticles, turning them into positively charged silver ions. The positively charged silver ions react with the negatively charged sulfhydryl groups in the bacterial protease, and the loss of the sulfhydryl group rapidly inactivates the protease, thereby killing the bacteria because they cannot reproduce. When the bacteria are inactivated, the silver ions will be separated from the bacteria and repeated sterilization activities, so its antibacterial effect is lasting.
