T. Allen: This is a prefilter. That means it pulls large dust, hair, large pollen from the air before clogging the more expensive HEPA filters. It is less expensive than the brand name Honeywell filters. Yes, it is thinner. Yes, it does require you to cut pieces to fit your particular machine. It's thin so it's easy to cut with scissors using the original filter as a template. You get 4-8 filters for the price of one "original" Honeywell filter depending on the size of your machine. You can double up the filter material if you want it thicker. DO NOT buy this if you are too lazy to cut your own filters. DO NOT buy this if you are going to freakout because it's thinner than the original. BUY this if you want to save money as it's good quality material (Oct 2020).

Kevin N.: Our outer filters were shredded so we replaced them with these and they work great! They were a tad bit too large but they were easy to trim to the correct size. Very pleased with the price as well! Great product.

TXAnimals: I last ordered these 12/2015 and am just now back for more. I vacuum them every couple of weeks and occasionally rinse them just with water. I don't think they're intended to be used like that but they've worked great as prefilters for my various sized air purifiers. I'm only getting more now because I think I've exhausted their odor absorbing ability, but to be clear that's because I use and reuse and clean them. Amazingly, the price is a penny cheaper today (4/2017) than a year and a half ago! Yay for quality and price. I'm a happy pet owner :)

Tyler B: Works as intended. Made a box-fan filter using a few super-cheap furnace filters and this carbon filter. Does not have charcoal powder going everywhere like last batch I bought from different company. I use a few Flander EZ-Flow filters taped together with some of this carbon filter taped in the middle to make my box-fan filters to catch dust and reduce odor in my house. Makes for a much cleaner feeling home. After sandwiching a cut to size piece of this carbon filter in between the EZ-Flow filters and tape it up I put this filter assembly on the back of a standard box fan you can pick up at any store, tape it on with painters tape (won't stick on with residue like duct-tape) and you are good to go. Have to emphasize you put it on the back of the box fan, put it on the front and some of the air will actually blast backwards. Not only that, dust will collect in the fan over time. Put the filter on the back and it pulls the air through with much more strength, use the thin Flander EZ-Flow filters ($2.50 for 4 at my Wal-mart) since thicker normal filters will reduce airflow enough to burn up the fan motor.

Extra note on packaging, I had some charcoal filters get a hole in...
