I have used filters from Filtrete for other purposes in the past (like home HVAC systems) and have had good luck. Of all the filters available for my Bissell Cyclonic I was hoping this would be the best. I have no other way of proving this other than to tell you that it filters better than the previous Arm & Hammer filter I had. I know this because compared to the A&H I see less (virtually no) dust and it gets dirty quicker. which means it picks up more dust and dirt. That's what you want. Dust and dirt in the filter and not floating in the air of your house or apartment.
