I was more than satisfied with this replacement filter. I work with photopolymer resin making 3D prints, which is a very smelly process: the resin smells, the alcohol used to clean the finished prints smells, and the combination of alcohol and resin is probably one of the most obnoxious smells I've ever experienced. I bought a MyAir air purifier because the cost was reasonable, and it was listed as having a carbon filter. It obviously did not. The original filter was skunked in a matter of a week or so, to the point where the air coming out of the purifier stank more than the air going in. I bought these filters as a replacement and the difference is pretty much night and day. First off, they are visibly different. The photo I added shows the ADDFRESH filter on the left and the original Bissell filter on the right. The ADDFRESH filter is darker, which I am assuming is from the actual presence of carbon in the filter. It fit perfectly and I had no issues closing the filter chamber on the purifier. (An issue that several people reported in past reviews. I assume they fixed it) There was a slight scent from the air purifier at first, and I'm unsure if this was from the filter itself or just lingering odor from the chemicals that have passed through this machine in the past. Either way, the scent was unobtrusive and faded after about a week of use. (I did not encounter a "STINK!" like other customers have commented on) Now my air purifier does a MUCH better job at stripping the lingering alcohol and VOC odors out of my workshop. Before the filter change, even my big exhaust fan couldn't suck all the odor out. This was a good buy. I recommend it.
