> 3 dayThe only con I have is you have to cut the A Filter to size. I messed up my first sheet and cut it too small. I would still buy it again for future supply.

09-06-2025This pack was supposed to come with 3 Hepa filters and 4 activated carbon pre-filters. Instead it only came with 2 Hepa filters and extra carbon pre-filters. It is useless since I can not use my air purifier without all of the Hepa filters.

> 3 dayMy air purifier helps keep allergic reactions and asthma under control. Scoops up a ton of dog hair and even helps when summer forest fires in the mountains turn the air brown. BTW I dont get the noise level line item since the filters dont make any noise.

> 3 daySo the mini rectangle white filters were good but instead of the rectangle black filters, horrible. They sent like a big folded over sheet and I have to cut it down to size. Either someone just packed it wrong or something.
