ULPA filters trap more particles and are smaller than HEPA filters. ULPA filters are 99 to 99.999% effective in removing submicron particles of 0.12 microns in diameter or more, while HEPA filters are 99 to 97% effective in removing particles of 0.3 microns in diameter or more. ULPA filters have an efficiency rate of 99.999%. Therefore, ULPA filters provide greater filtering efficiency, which translates into better protection for the operator, the product and the environment.
MERV 13 filters are less expensive than HEPA filters and can be used in a wider variety of configurations. MERV 13 filters are also more efficient at removing large particles from the air. HEPA filters are the most commonly used filtration technology in both commercial and residential environments. It is due in part to its effectiveness in capturing 99.97% of 0.3 micron particles and is efficient in commercial spaces and residential.
As defined by the DOE, HEPA filters can capture up to 99.97% of airborne particles with a size of 0.3 microns (µm), also known as the most penetrating particle size (MPPS). Unfortunately, because of the trademark, a HEPA-type filter can be sold under the pretext of misleading consumers into believing that the HEPA type is similar to or as effective as real HEPA.
When looking for portable air purifier solutions for your facility, it's critical to know the difference between HEPA filters, true HEPA filters, HEPA-type filters, and other types of HEPA filters.
This reduction is due to the fact that air first passes through the HEPA filter and goes through the UV-C process. Many consider HEPA air purifiers to be the best option, but there is a filter that technically blocks more contaminants in the air.While the filter may still be able to capture 0.3 micron particles and capture a high percentage of them, unless it is confirmed to be true HEPA, it cannot claim to meet DOE HEPA standards. You can effectively remove dust, pet dander, pollen, bacteria, viruses, and other airborne contaminants with a durable, water-resistant True HEPA filter. HEPA filters can be used in any environment, including industrial, commercial, healthcare and consumer. These considerations with respect to HEPA filters are essential when their objective is to reduce viral transmission by aerosol.
With a similar design compared to a HEPA filter, ultra-low particle air filters (ULPA) have a dense network of randomly arranged fibers. According to the EPA, a HEPA filter must remove at least 99.97% of the largest particles, at least 0.3 microns in size. HEPA is a type of pleated mechanical air filter known as a high-efficiency particulate air filter and refers to its air quality cleanliness measurement developed by the Department of Energy (DOE) in the wake of the Manhattan Project in the 1940s. Both HEPA and ULPA filters are designed to trap very small contaminant particles from an air stream by forcing air through a fine mesh.
