What is the Best Air Filter for Your Home: HEPA vs ULPA

When it comes to air filtration, there are many options available on the market. From MERV to HEPA to activated carbon and ultraviolet (UV) germicidal irradiation, it can be difficult to know which type of filter is best for your home. In this article, we'll take a look at two of the most popular types of air filters: HEPA and ULPA. HEPA filters are the most commonly used filtration technology in both commercial and residential environments.

They are designed to capture particles of 0.3 microns in size or larger and have an efficiency rating of 99%. True HEPA filters are 99.97% effective in removing submicron particles of 0.12 microns in diameter or more. On the other hand, ULPA filters are even more efficient than HEPA filters. They have a dense network of fibers arranged randomly and are 99 to 99.999% effective in removing submicron particles of 0.12 microns in diameter or more.

When looking for portable air purifier solutions for your facility, it's crucial to know the difference between HEPA, True HEPA, HEPA-type and other types of HEPA filters. While a HEPA-type filter may seem more impressive compared to the 0.3% effectiveness of True HEPA, it's not as effective as ULPA filters. The carbon prefilter also captures smoke, odor, harmful gases and volatile organic compounds (VOCs), which HEPA filters cannot trap. Today, HEPA and ULPA filters are designed to capture airborne particles and work in a similar way. For residential use, ULPA filters are generally considered to be better than HEPA filters. However, if you're looking for an air filter that can effectively remove dust, pet dander, pollen, bacteria, viruses, and other air contaminants, then a durable, water-resistant True HEPA filter is your best option.
