Review on Replacement Filters Cyclone Absolute 969082 01 by Donald Shah

Bought to have on hand if the original gets dirty and hasn't been used yet. Seeing inoperability questions from others, I gave it a try. I noticed that after removing the main plastic cover, there was another piece of plastic over the vent. I took it off and then screwed it on and tried a vacuum but no response. I think I shot it extra and then it worked fine. I would make sure all the plastic is removed and you rotate the setup a bit. Maybe I'm not as perfect as the original.
