When it comes to air filtration, there are many different types of filters available on the market. The type of filter you need will depend on the specific needs of your installation. Some common types of air filters include MERV, HEPA, activated carbon, and ultraviolet (UV) germicidal irradiation. But what is the difference between HEPA and ULPA filters?ULPA filters are more effective than HEPA filters in trapping particles, as they are able to capture particles as small as 0.12 microns in diameter.
On the other hand, HEPA filters are only able to capture particles of 0.3 microns in size or larger. The filter works by sucking air through itself and trapping particles in the network of fibers that make up the filter. Many consider HEPA air purifiers to be the best option, but there is a filter that technically blocks more airborne contaminants: MERV 13 filters. These filters are less expensive than HEPA filters and can be used in a wider variety of configurations. The only material difference between a HEPA filter and a ULPA is the density of the borosilicate fibers.
While the filter could still capture 0.3 micron particles and capture a high percentage of them, unless it is confirmed to be a true HEPA, it cannot claim to meet DOE HEPA standards. HEPA air filters are particularly good at removing particles such as mold, pet dander, dust, and other allergens. Taking advantage of ionization technology allows you to capture more airborne debris so that the HEPA filter can do its job more efficiently. When looking for portable air purifier solutions for your facility, it's essential to know the difference between HEPA, True HEPA, HEPA-type and other types of HEPA filters. While this may seem like ULPA filters are better than HEPA filters, the opposite is actually true for residential use. The EPA has set standards for air filtration systems that must be met in order for them to be considered effective. According to the EPA, a HEPA filter must remove at least 99.97% of the largest particles, at least 0.3 microns in size.
These filters remove more contaminants from the air than HEPA filters, and require 99.99% with a target particle size of 0.1 microns. A HEPA filter, on the other hand, will allow air to circulate much faster, leaving the air cleaner than a ULPA filter. These considerations with respect to HEPA filters are essential when the objective is to reduce viral transmission by aerosols. The team of experts at P Fedder is always available to answer any questions you may have about MERV 13 filters compared to HEPA filters or any other air quality questions you may have. HEPA filters are the most used filtration technology both in commercial and residential environments. In conclusion, when it comes to air filtration, there is no one-size-fits-all solution. It's important to understand the differences between different types of air filters so that you can make an informed decision about which type is best for your needs.
