Query: Not a HEPA Filter -- BIg difference -- Beware

If you have bad allergies and need a HEPA filter, beware of phrases such as "HEPA-like" and "90% HEPA". They are NOT nearly as good as the real thing.By its own description, this filter lets through over TWENTY TIMES as much as a real HEPA filter, and if you have bad allergies the difference is massive. HEPA is a specification that must be met before you can use the term. Specifically, it must block "at least 99.97% of airborne particles 0.3 micrometers (m) in diameter". This filter, on the other hand, removes "up to 99%" of particles.Shame on Honeywell for slapping "HEPA" on all their filters even when it doesn't apply.
