HEPA Filter Concept:
High-efficiency particulate Air, or HEPA. It is made of very fine fibers interwoven, the ability to capture particles is very strong, pore size is small, adsorption capacity is large, purification efficiency is high.
According to the calculation of single filtration rate, the standard HEPA filter can filter the air small to 0.3 micron (1/200 of the diameter of hair) of particles, the filtration rate of at least 99.97%, haze and bacteria, viruses, fungal spores and other pollutants the most effective filter media, that is to say:
Only three out of every 10,000 particles can penetrate the HEPA membrane. Therefore, its filtering effect of particulate matter is very obvious!
When used to filter cigarettes, the efficiency is almost 100 percent, because particles in cigarettes are between 0.5 and 2 microns in size and cannot pass through the HEPA membrane. The main role is to filter the air side of the particle, its best filtration performance can reach 99.999995%.
HEPA Filter Material:
HEPA points PP filter paper, glass fiber, composite PP PET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber five materials.
HEPA Filter Grade:
ccording to the specifications, it can be subdivided into H10, H11, H12, H13 and H14. All the HEPA of these specifications belong to the HEPA filter. The higher the HEPA grade, the higher the one-time filtration rate. However, the higher the grade, the greater the wind resistance, the greater the noise, the more expensive the cost. It is generally recommended that household filter products be rated H11 ~ H12. For example, IAM air purifiers in Britain are rated H11.
HEPA Filter Application
HEPA is an internationally recognized high-efficiency filter material. Originally, HEPA was used in nuclear energy research and protection, but now it is widely used in precision laboratories, pharmaceutical production, atomic research and surgical operations where high cleanliness is required, and the household air purifier .

What is the Air filter / filter element ?
Air purifier filter generally has pre-effect filter, medium effect, HEPA filter, activated carbon filter and so on.
The thickness, fineness (mesh ) and placement of each layer of filter , function and service life are not the same.
The Pre-effect filter is generally placed in the first layer, with the shortest life and the need for frequent replacement;
Second to medium effect filter, placed in the middle; Hepa filters are usually placed in the last layer and have the longest life.
The main performance is to capture of small solid particles in the air, efficiency fromH11-H14.
And the activated carbon filter screen mainly adsorbs the harmful gas in the air, so as to achieve the effect of purifying the air.
