Filters meeting the HEPA standard must satisfy certain levels of efficiency. Common standards require that a HEPA air filter must remove at least 99.95% (European Standard) of particles with a diameter of 0.3 microns; particles between 0.2 and 0.3 microns are the most difficult sized particles to capture, while particles both larger and smaller in size are more easily captured.HEPA H13-H14 are within the highest tier of HEPA and are considered medical grade quality. HEPA H13 and H14 trap 99.95% and 99.995% of such particles, respectively.
By definition all HEPA filters are individually certified to conform with their target efficiency and higher efficiency filters are 100% scanned for leaks. The data from the testing is provided on a label on every filter stating test airflow, resistance to airflow and penetration (the inverse of efficiency).
Enjoy enhanced air quality and peace of mind with our DGC top-notch HEPA filters.
