Today, our living environment is getting worse and worse. Many families pack air filters to filter the air in the house. But we also know that when we buy air filters, first we need to know the material of the air filter so that we can choose the air filter that is useful to our family. What are the air filters?
Air filter material - what is air filter
The air filter (Air Cleaner) is mainly used in the fields of pneumatic machinery and internal combustion machinery. The belt type vacuum filter provides clean air for these machines in order to prevent the mechanical equipment from inhaling air with impurity particles in the work and increasing the probability of abrasion and damage. The main component of the air filter is the filter core and the shell. The filter core is the main filter part, and the filter is the filter of the gas rubber belt filter, and the shell is the external structure to provide the necessary protection for the filter core. The working requirements of air filters are high efficiency air filtration, excessive resistance to air flow and long continuous work.
Air filter material HEPA grade filter paper
HEPA filter paper is the most common filter net of air filter at present. It can purify the particles of more than 0.3 microns by vacuum belt dehydrator. The removal effect is 99.7%. Especially for PM2.5, the effect is more obvious. It is a filter which is very recognized by consumers. But want HEPA filter paper to play the maximum energy efficiency, select the grade and standard of HEPA grade filter paper needs special attention, because the specification and grade of HEPA grade filter paper will be influenced by many factors such as the design of the purifier itself and air flow, if it is a poor quality manufacturer of air purifier, although it is used It is HEPA filter paper, but the design of the outer layer of the purifier is not reasonable and the material is poor, it will lead to the leakage of the edge of the filter material and influence the filtering effect of the filter net of the HEPA grade filter paper.
Filter material of air filter - activated carbon filtration
We all know that the adsorption capacity of activated carbon is the most powerful, but the single use of activated carbon is not obvious, it is necessary to use another technology to make the efficiency of activated carbon to the extreme. Now some manufacturers have proposed a new type of nanoscale photocatalyst - activated carbon fiber composite filter medium, which uses the adsorption capacity of activated carbon particles to adsorb all the toxic and harmful gases in the air on the surface of the activated carbon carrier and then remove these gases. Activated carbon can adsorb gas below 0.3 microns, which is more powerful than HEPA filter paper, and it is convenient to wash and rinse directly with water. But the activated carbon needs to be replaced once a year to reduce the adsorption capacity of activated carbon.
Two kinds of common air filter materials are introduced in this paper. The general family will choose the two materials as buyers. Before we buy, we should consider the needs of their own families, and consider the material of the air filter, and consider the brand of the air filter. We can buy high quality products.
