Perfect for my Hoover Flair vacuum cleaner. I have to vacuum my bedroom every day as my dog sleeps on the carpet every night. That means I have to clean the vacuum cleaner about once a week. Now I can replace the filter, wash it and let it dry and have a backup in the meantime. Made of high quality material, it is washable and reusable, which is good for the environment and my wallet. It took a little longer than I expected, around two weeks, but it wasn't too bad, I had to wait longer for other sellers. Overall a good product and good service.
