Filter Screen Technology For Air Purifier
High performance particulate air filter (HEPA) is one of the hottest technologies used in air purification. The standard HEPA filter is able to absorb particles of 0.3 micron size 99.7% (0.3 micron filter size is the most difficult, but it's also a drag) is relatively large, rarely used in the air purifier, air purifier manufacturers claim that the actual HEPA is actually the filtration efficiency is not really HEPA it is slightly lower than HEPA. The wind resistance is relatively low. Whether it is the real HEPA or the publicity HEPA is to make the inhaled air fresher and clean. The filter absorbs chemical fumes, bacteria, dust particles and pollen, and after filtering through the air purifier, there are no pollutants in the air.
The advantage of HEPA filter is effective and safe. It is the most important technology to remove particulate pollutants in air, but the disadvantage is that it can only remove suspended particles and filter harmful gases. The air cleaner using HEPA has a good airtight design, otherwise the air will go around the filter and lose the filter effect.
