Review on EnviroCare Premium Replacement HEPA Filters for Royal Dirt Devil Type F1 Bagless Upright Vacuum Cleaners by Susan Stephens

Other people have mentioned having to modify the vacuum with tape or something to make sure it's tight. I had to do the same and I wouldn't do it again. It feels like I was faking it and I hate that feeling. While I think it will hold up and do the job, I can't say it doesn't work. I'm just saying that I don't like the product itself for its inconveniences.
