fit and function same as original. Good to have backup filter so you can rinse one and use another while the first one drys. they are rinsable if you use a gentle spray from a kitchen sink sprayer etc. have used and rinsed 20+times with no degradation of filter.
these seem to work well, but any of them need to be cleaned just about every time you use your sweeper. they are getting very hard to find, so I may look into getting a new sweeper. I feel these are over priced also
