> 3 dayThe size A filters are oversized and need to be cut. They also arrive folded. The crease marks from the folds cause the pre filter to popped out of its holder

08-06-2025Perfect fit. Noise of machine immediately got less than before changing the old one out! Definitely cuts down on dust… I haven’t changed mine out in at least a year so that’s why they got so bad but still great work!

> 3 dayI am always concerned when not using the name brand for replacements like these. However the name brand is so expensive so I thought I would try them and see. Works great and is as functional as the name brand. No prolems and works the same.

Greater than one weekMy 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 dayThis 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 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.
