Here Are The Top 10 Best True HEPA Air Purifiers 2023

Alphachooser's list of the newest True HEPA Air Purifiers includes only air purifiers that obey to these criteria:
  • HEPA filtration truly matters to avoid recirculating certain particles in the air and are universally recognized as the best choice to filter: dust, germs, viruses, allergens, pet hair and other cat & dog allergens, etc.
  • For this list, we focus exclusively on True HEPA air purifiers, that is those for which we could confirm the minimum filtration of 99.97% of airborne particules that are at least 0.3 micrometers in diameter.
  • By the way "True HEPA" is just a marketing name to distinguish some products from HEPA-style filters, which may not meet the standard.
