We have replaced the original filters on our Bissell with these off brand versions. I was a bit concerned that they would contain inferior materials (plastic body, rubber sealant, paper filter and sponge), but I couldn't find any significant differences in fit and finish (e.g. sealant bonding the paper filter to the body). ) or materials. Since they are disposable and not intended to be used for many years, I don't see why they wouldn't work as well as the more expensive branded versions. I will update my review if they fail prematurely)
