People Also Ask

What is a Medical Grade Air Purifier?

Looking for air purifiers, in general, can be confusing, but combing through medical-grade air purifiers can be even more daunting. While the term “medical grade” isn’t regulated in regard to air purifiers, you’ll typically see air purifiers utilizing an H13 HEPA filter listed as medical grade. This is simply because H13 HEPA filter technology is the filtration level most used by hospitals and other medical facilities.

This means that any air purifier using an H13 HEPA filter could be considered medical grade. Some H13 HEPA air purifiers also include other key technology commonly used in medical space air purification, such as germicidal UV-C light, electrostatic filtration, and activated carbon to further increase levels of filtration.

What is the Best Medical Grade Air Purifier?

The PuraShield 500 tops our list of medical grade air purifiers due to its combination of high level filtration technology. Far more than a simple HEPA filter, the PuraShield 500 air purifier includes 22 lbs. of patented molecular filtration media, as well as a layer of silver and copper ions to protect the main filter.

But what really makes the PuraShield 500 stand out against other HEPA air purifiers is its effectiveness against SARS-CoV-2, the virus that causes COVID-19. This makes it by far the best medical grade air purifier for classrooms, offices, small businesses, and those who want to ensure the highest level of protection against airborne microorganisms.

What Does HEPA Mean in Medical Terms?

HEPA is an acronym for the term Highly Efficient Particulate Air (filter) and is used to identify filters that meet specific requirements laid out by the Institute of Environmental Sciences and Technology.

In medical terms, HEPA means that a filter has been tested and proven to remove up to 99.97% of particulates down to 0.3 microns, which is about 300 times smaller than the diameter of a single human hair. This means HEPA air purifiers are sufficient to remove most mold, pollen, dust, dander, viruses, and bacteria.

Why are H13 HEPA and H14 HEPA Filters Important?

Ensuring that your air purifier uses an H13 HEPA filter is important because this is the level of filtration that’s considered medical grade. In order to be classified as a HEPA filter, the filter media needs to capture 99.97% of particles as small as 0.3 microns. 

In Closing

We hope that this list of air purifiers has helped you narrow down your search. Every air purifier on this list will provide medical-grade filtration, and there really are options for every size space and budget. As you review your options, remember to factor in the frequency and cost of replacement filters, ease of maintenance, and overall durability.
