Review on 🔍 DerBlue 6PCS True HEPA Replacement Filter B for Holmes HAPF600, Improved Holmes Air Filter, Part # HAPF600, HAPF600D, HAPF600D-U2, White by Michael Herrera

Excellent DerBlue! First, the delivery was great! Items were boxed, sealed and packed perfectly without any damage whatsoever. Second, I can't tell the Holmes filter apart from DerBlue. In terms of thickness, folds and fit, everything is the same. It was easy enough to change the filter on my little black Holmes air purifier. The included charcoal filter is nice and thick and perfect for the retaining tabs on this "B" type HEPA filter. The mounting tabs are OEM gauge and you don't have to worry about them breaking, as some other reviewers with non-DerBlue brands have noted. I bought 3 packs (total 6 items). In the future I will only buy DerBlue filters.
