Problems solved by technology

[0003] The purifier filter elements used in conventional air purifier products often disperse activated carbon and other similar particles into plastic parts with a honeycomb structure. Although they can remove odorous gases such as formaldehyde in the indoor environment, they are limited by this structure. Restricted, cannot realize the function of fast deodorization and purification

Abstract

The invention relates to a composite air purifying filter paper material and a filter element using the same. The composite air purifying filter paper material comprises an active carbon fiber pre-filtering layer, an adsorption catalytic particle layer, a particulate matter filtering layer and a sterilizing supporting layer which are superposed according to any sequence. Compared with the existing filter paper material, the composite air purifying filter paper material is provided with the active carbon fiber pre-filtering layer; an air purifying filter element prepared from the composite air purifying filter paper material can significantly improve quick purification and adsorption performance on pollutant molecules, such as peculiar smell and the like, in the environment, and the removal rate of the whole filter element on gas-state pollutant molecules is increased.

Description

technical field [0001] The invention relates to a composite air purification filter paper material and a filter element using the same, belonging to the field of air purification. Background technique [0002] With the improvement of people's living standards, various new decoration materials are used in indoor home life, causing the problem of indoor environmental pollution to gradually intensify. Among many indoor pollutants, formaldehyde is one of the most serious gas pollutants. It is colorless and has a strong pungent smell. It has been identified as a strong carcinogenic and teratogenic substance by the World Health Organization (WHO). Studies have shown that the release cycle of formaldehyde is as long as three to fifteen years. my country's national indoor air quality standard stipulates that the hygienic standard for formaldehyde in the air of residential and office spaces is 0.10mg / m 3 (GB / T 18883-2002). Long-term exposure to low-dose formaldehyde can easily cau...
