are great replacement filters. My originals were so dirty (too bad I didn't know there were 3 filters and not just one!) that I couldn't clean them. I took a chance because of the reviews, the value for money and not being able to order them online from Shark. to buy them you need to call SHARK to order. these fit almost perfectly. The motor filter was a bit larger, but I mounted it without cutting. now my shark picks up debris and small particles again. I couldn't be happier. I will definitely buy them again!”
