Can the HEPA filter remove the Novel Coronavirus?
Common standards require that a HEPA air filter must remove—from the air that passes through—at least 99.95% (European Standard) or 99.97% (ASME) of particles whose diameter is equal to 0.3 μm; with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm. A HEPA filter is a type of high efficiency particulate air filter. This type of air filter can remove at least 99.97% of airborne particles 0.3 micrometres in diameter. Particles of this size are the most difficult to filter and thus the most penetrating particle size. Particles that are larger or smaller are filtered with even higher efficiency.
Therefore, HEPA Filters can definitely filter out the Coronavirus which are approximately 0.125 μm in size at close to 100% efficiency. The general misconception is that HEPA Filters work like a net or a sieve and block out particles of certain sizes. However that is incorrect. HEPA filters are designed to target particles much smaller than 0.1microns as these particles adhere to the fibers by diffusion at almost a 100% rate.
What type of UV Light is it?
It is a UV-C Light. UVC has been shown to be effective at killing or inactivating microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. Ultraviolet lamp intensity: 2260uW/cm3, Wavelength: 265-285nm
