HEPA and H13
7of 52 listings print it
Printed as: HEPA · True HEPA · H13 true HEPA · IEST certified HEPA. The listing prints HEPA or H13 as a word of its own; HEPASilent does not count.
What it is
EPA describes HEPA as a type of pleated mechanical air filter, an acronym for high efficiency particulate air filter as officially defined by the U.S. Department of Energy. EPA’s page says a filter of this type can theoretically remove at least 99.97% of airborne particles with a size of 0.3 microns. That is EPA’s description of a filter type, not a measurement of any listing here.
IEST, the Institute of Environmental Sciences and Technology, publishes IEST-RP-CC001.7, a recommended practice covering HEPA and ULPA filter units, and describes itself as an ANSI-accredited standards-developing organization. Like AHAM Verifide, it is not a government program.
Who runs it
EPA describes it; IEST publishes a practice
No single program stands behind HEPA on a consumer listing. EPA points to the Department of Energy’s definition, and IEST publishes a recommended practice for HEPA filters.
What it does not promise
- HEPA and True HEPA on a listing are the seller’s words. The site checked no filter, and it does not compare these units by how well they clean.
- The Core 300-P listing prints
99.97%
as its own claim. The site does not treat that as EPA’s figure applied to that product.
H13
The FULMINARE listing prints H13
. The site could not tie those letters to a published document it was able to open and link, so it repeats them as printed and does not explain them.
HEPASilent
The Blueair listing prints HEPASilent filtration
. That is a seller’s name for its filtration, and the site does not count it as the word HEPA; one listing is left out of the count for that reason.
