                          Does HEPA filters really work with PM 2.5 filtration?

                          High efficiency particulate air (HEPA), is one of the most popular options for Air Purifiers. Though different filtration levels apply, our standard HEPA can filter 99.7% of particles in 0.3 micrometers (μm) in diameter. With additional methods, our combination of filters can clean the air so chemical particles, bacteria, pollen, and dust will all be pulled out from the air.


                          The advantages of HEPA filters include its reliability and filtration effectiveness. Though it’s more effective than electrostatic filter, but the downside is that it only filters particles in the air, excluding chemicals and bacteria. Plus, the high wind resistance makes it a natural habitat for bacteria. Air purifiers need to have a good air tight design; otherwise particles will get through it by surpassing the filter.
