I have had a vacuum cleaner for many years. I've washed/rinsed my filters many times but they eventually got to the point where they were almost permanently dirty. These replacement filters were cheap enough to try. Holy prayer! It's like a new vacuum cleaner! I also love that I now have multiple filters to rotate while one set cleans/dries. Cool Tip: Make sure you check your model number as there are several filter sizes that are slightly different and look the same.
