Original contribution: RE: HEPA filter written by Mike Edgington on 4/14/2004 at 12:40) This is true. However DOP testing is now commonly replaced by EMERY testing (methodology is the same though, but the Di-Octyl Phtalate is no more used).
FDA expectations is a yearly testing for class 100,000 HEPA filters, and a semestrial testing for class 10,000 & class 100 (critical filters).
Hope this helps.
