Product advantages and longevity

Activated carbon is a kind of porous carbonaceous material with highly developed pore structure and is an excellent adsorbent. Activated carbon adsorbent has many advantages, compared with other adsorbents have the following characteristics: 1. The surface characteristics of the active carbon have a surface chemical property, different pore size distribution and pore shape, which is the main reason for selective adsorption of activated carbon. 2. Chemically stable, easy to regenerate. The activated carbon chemically stable, can resist acid and alkali, so that can be applied in a wide range of PH. Activated carbon are insoluble in water and other solvents, and can be used in aqueous solution and many solvents. 3. Catalytic activated carbon is used as a contact catalyst in various isomerization, polymerization, oxidation and halogenation reactions. Its catalytic activity is due to the effects of carbon surface, surface compounds and ash content. 4, more developed pore structure of activated carbon having a well-developed pore structure, in addition to the activated molecular sieves, a wide range of pore size distribution with different pore size pores,can absorb different molecular size of various substances. In addition, when choosing the activated carbon adsorbent, the following principles should be followed: 1. Good selection performance; 2. It has the characteristic of low vapor pressure, non-foaming, low intrinsic point, so that the loss of absorbent is small; 3. Small corrosive, almost not have it; it is not easy to burn, low viscosity and good chemical stability; 4. Its use time can be recycled. After 3-6 months of use, it can be exposed to sunlight to restore part of the adsorption effect.

Product Features

HEPA is interleaved by very small organic fibers, with the stronger particles capture ability, small pore size, high adsorption capacity, high purification efficiency, and water absorption,against 0.3 micron purification rate 99.97%. In other words per 10000 particles, only three particles can penetrate the HEPA filter membrane. The effect of HEPA filtering particulate matter is very obvious. If you filter the cigarette with it, the filter effect can be almost 100%,because the particles in cigarettes are between 0.5-2 microns in size and cannot pass through the HEPA filter membrane, not by HEPA filtration membrane . The average service life can be up to 6-9 months, and the actual service life will be different depending on the local time and environment. The filtration efficiency of HEPA high efficiency particulate filter is proportional to its surface area. The HEPA high-efficiency particle filter of air purifier is folded in multiple layers, and the expanded area increases by about 14.5 times compared with the folded area, so the filtration efficiency is very outstanding.

Application Scope

• Household and commercial air purifiers, fresh air ventilators, air conditioners, European style range hoods, air cleaners,  heater filters

• Microwave oven filter, dehumidifier filter, vacuum cleaner filter
