Review on VEVA Precut Premium Carbon Pre Filters 4 Pack for HPA300 HW Air Purifier - Easy Installation & Advanced Filtration by Richard Eledge

Filters match perfectly. I once replaced the filters with Kaz filters and the air purifier made a very loud noise. The lowest setting sounds louder than a good car's turbo. I thought the air purifier was defective and wanted to replace it. The cost of a new one was too high compared to the filters. I thought that the cleaner could also work as a white noise generator. After replacing the filters with Veva filters I was so shocked. the cleaner is so quiet again. It turned out that the problem was in the Kaz filters. Now the room is so quiet. I also tested the suction power with A4 paper. The Kaz filter was so noisy and couldn't suck in A4 paper to stick on. Veva filters easily absorb A4 paper. I have a feeling VEVA filters will be able to handle more air. The only drawback is the pre-filter. There was black dust in the zip bag. I'm sure it's carbon, but it's still annoying to be careful when taking it out of your pocket.
