Review on Quality Replacement Vacuum Filters for Bissell AirRam Vacuum 2144, 1984, 19841, 19844 (Pack of 3) by Evelyn Peterson

Great value for 3 packs as if you buy the OEM version you will pay a lot more. It's a tight fit, but work with care and it will stretch to the right length. I'm not sure how to properly clean them other than shaking them outside, but I probably wouldn't wash them. I washed the native filter several times, dried it thoroughly in the sun, but every time I turned on the vacuum cleaner, a stinky smell of mold came out (which is why I ordered a replacement). These should last a long time.
