What is the Difference Between a HEPA Filter and a Regular Air Filter?

When it comes to air filtration, there are several options available. But what is the difference between a HEPA filter and a regular air filter? HEPA filters are renowned for their superior efficiency in eliminating particulates from the air, making them ideal for those with respiratory issues such as allergies or asthma. True HEPA filters are even more effective, able to capture up to 99.97% of particles that measure 0.3 microns or smaller. On the other hand, regular air filters are less efficient and can only capture particles that measure 1.99 microns or larger. HEPA filters are pleated mechanical air filters that were developed by the Department of Energy (DOE) after the Manhattan Project in the 1940s.

They are commonly used in both commercial and residential settings and can effectively remove dust, pet dander, pollen, bacteria, viruses, and other airborne contaminants. Carbon prefilters can also be used to capture smoke, odors, hazardous gases, and volatile organic compounds (VOCs).When searching for portable air purifier solutions, it's important to understand the distinctions between HEPA filters, true HEPA filters, HEPA-type filters, and other types of HEPA filters. True HEPA filters are the most efficient and can trap up to 99.97% of particles that measure 0.3 microns or smaller. On the other hand, HEPA-type filters are lower versions of True HEPA and may not be as effective in removing particles from the air. It's also essential to consider diffusion when using a HEPA filter.

Diffusion occurs when particles collide with each other and are absorbed by the fibers of the filter. Leveraging ionization technology can help capture more debris in the air so that the HEPA filter can do its job more efficiently. When your goal is to reduce viral transmission by aerosol, these considerations about HEPA filters are critical.
