Review on 🍃 Honeywell Universal 14-inch Air Purifier Replacement HEPA Filter: HRF-F1 / Filter (F), White - Superior Air Cleaning Efficiency by Alexa Olea

Well I know where the noise is coming from on these replacement filters. What am I talking about? The replacement sheets are 1/2 or 1/3 the size of the originals and must be stacked on top of each other. You lose most of the filter area due to the extra rubber in the middle. Changing the filter size creates an unacceptable amount of new noise. And that's not the noise that the filters originally created. It's more like a jet engine taking off and a little louder. We bought the best brand of HEPA filters to replace. At least they didn't smell like some of the spares we've gotten in the past. I cannot recommend these replacement devices.
