Information

HEPA activated carbon composition filter for house is mainly used for oil fume purification; supporting various household and vehicle air conditioners and air filters; water purification, gas phase adsorption, etc. It can be used alone to remove dust, smoke, odor, and volatile organic pollutants such as benzene and formaldehyde; it can also be combined with ultra-fine meltblown fibers and coarse filter cotton to achieve higher dust filtration and deodorization effects.

HEPA activated carbon composition filter for house

Application of HEPA activated carbon composition filter for house:

1. The chemical filter is suitable for airports and hospitals, which can effectively remove peculiar smells in the air.
2. It is used for air filtration in public places such as office buildings, museums, archives, libraries, etc. It can remove polluted gases such as sulfur oxides and nitrogen oxides in the air and protect collections from damage.
3. Used in the semiconductor and microelectronics industries, it can effectively remove "molecular-level pollutants", improve product quality and protect personnel health.
4. When used in animal laboratory, it can reduce odor, improve the quality of laboratory animals, and protect the atmospheric environment at the same time.

The filtering principle of HEPA activated carbon composition filter for house:

HEPA activated carbon composition filter for house selectively adsorbs gaseous pollutant molecules instead of mechanically intercepting impurities like a dust filter. Adsorption is the adsorption of gas or liquid molecules on the surface of a solid substance, in which the solid substance is called an adsorbent, and the adsorbed substance is called an adsorbate.
Adsorption can be divided into physical adsorption and chemical adsorption. Physical adsorption mainly relies on van der Waals forces, which are often carried out at lower temperatures, and the process is a reversible process. For some gases (such as ammonia and hydrogen sulfide), the adsorption capacity of ordinary activated carbon is limited. At this time, people often chemically treat them to enhance their ability to remove specific pollutants.
Adsorption in which chemically treated adsorbents react with harmful gases is called chemisorption, and the process is irreversible. The adsorption process can be divided into three stages: gas molecules diffuse to the outer surface of the activated carbon, referred to as external diffusion; gas molecules diffuse to the inner surface in the activated carbon micropores, referred to as internal diffusion; on the inner surface of the HEPA activated carbon composition filter for house gas molecules are absorbed suck.
