Review on DerBlue Replacement HEPA Filters: Improve Air Quality with AER1 Type Total Air Filter, HAPF30AT for Holmes Purifier HAP242-NUC by Matthew Carr

I don't know about you, but paying $22.99 for 2 of these filters isn't the best option. I have 3 air purifiers due to my wife's condition and paying $65 makes no sense. Why pay more when you don't have to. As far as I can tell these filters are the same as the more expensive brands. I think they're even better, since the plastic ring around the front of the filters that comes in contact with the inside of the cleaner doesn't seal properly on expensive filters, these filters have a "silicone" based ring that gives good gripping power has the inside of the cleaner. . I plan to buy more in January. This is a great replacement!
