When I opened the box to install a filter, I was impressed with the quality of the filters.
I used weather stripping to keep the filter centered inside the return vent and it stopped rattling.
93% liked the long-lasting filter, while 7% thought it needed frequent replacements
I change the filters every 2 months and the 6 pack gives me a good year supply.
After changing the filters every three months, I could have used them for another month.
I change the filter every 60-90 days in my 1300 square foot home with three dogs.
After using it for a month, the filter gets filthy.

87% appreciated its high filtration efficiency, while 13% thought it was mediocre
Fewer pleats result in less surface area, which means fewer pores for air to flow through, thus higher resistance and quicker plugging of pores.
85% appreciated the quieter operation, but 15% didn't notice a difference
The product works well and has helped me with a family member who is sensitive to smoke particles.
I noticed that the filter produces a hissing sound as air passes by it because it is loose in the enclosure.
The air intake is loud due to the filter.
