Can Hepa Net Of Air Purifier Filter Novel Coronavirus?

In the past few years, many people have been immersed in the panic brought by novel coronavirus. The emergence of novel coronavirus has made these years unforgettable. In the epidemic situation, the most popular product is the mask. In addition to the mask, the air purifier has also become the "top leader" in sterilization. Of course, given the high price of the air purifier, many people have doubts about its effect after buying the air purifier.

HEPA is currently the most widely used

It can filter pm0.3 and finer particles. Generally speaking, whether it is an air purifier or a fresh air system, there will be primary, medium and high efficiency filters. The primary effect is to filter large particles such as pm10 and leaves; In medium efficiency, many enterprises use activated carbon to filter, which is mainly used to sterilize and filter harmful substances such as formaldehyde; The high efficiency is to filter the finer substances of pm0.5 and pm0.3.

HEPA high-efficiency filter screen

Among purifier products, HEPA high-efficiency filter screen is the main device that can effectively filter harmful substances such as bacteria and viruses. In fact, HEPA high-efficiency filter screen has lower filtering accuracy than N95, which is recognized as effective in the market. According to professional data testing, N95 mask can effectively filter 0.3 micron droplet cores, and its interception efficiency is as high as 98% in the face of novel coronavirus transmitted through droplets, which can effectively prevent novel coronavirus from being transmitted through droplets.

Due to different materials, HEPA high efficiency filter screens of air purifiers have different filtering accuracy. Generally, HEPA filter screens are made of five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt blown polyester non-woven fabric and melt blown glass fiber. According to the professional data test, the medical grade H13HEPA filter screen can remove more than 99.7% of particles with a diameter of less than 0.3 μ m, and 95% of bacteria and viruses with a diameter of 0.1 μ m. HEPA net is an effective filter medium for pollutants such as smoke, dust, bacteria and viruses. At the same time, medical HEPA filter is an internationally recognized high-efficiency filter material. For those who have the strength to use H13 medical grade HEPA filter air purifier, it can indeed play a good role in preventing novel coronavirus.
