I am very picky about the replacement filters I use in my Shark IonFlex Duo Clean IF250 vacuum because I once bought inferior filters and they didn't fit. I felt like I had to force the filter door shut and breaking the motor on an expensive vacuum just isn't worth it. Filters are NOT the place to save money. I tried this set because I was intrigued by the soft replacement brush head that came with it. I've never seen anything like this in a set. The brushroll fits perfectly edge-to-edge, although I've noticed that it's not as thick as the OEM brush it replaced. It still cleans my carpets and bare floors well, but I don't know how much it can miss when the filters get a little dirtier and it relies more on rollers than vacuuming to remove dirt from the carpet. This kit contains: - 4 felt foam filters. Brush for cleaning the dust filter housing with a seam ripper on the other end to remove hair from the brush heads. Great filter set for the price and I would rate it five stars if it included two more HEPA filters. The HEPA filter is central to the price point, which keeps foam filters from getting as dirty as they are, if not more so. However, unlike the foam filters surrounding it, it cannot be washed. Normally when I change filters I just throw away the entire assembly, so I found it odd that this well thought out kit only comes with two. I would recommend it!** If you found this review helpful, please take a moment and click the button below to let Revain know. Thank you π **
