I never write reviews. I just don't care. But it was a great experience. I went online to find a foam filter that I take off and wash every week because one of my cats found it while air drying (I have 5 cats) and chewed off part of it. Also, after over a year of rinsing it has become a little ragged every week. These replacement filter elements fit my Shark perfectly and others have indicated that the replacement elements are better than the ones that originally came with the vacuum. I was confused by the larger filter that came with the foam filters. It turns out it replaces a filter I didn't even know existed. Yes, I haven't read the manual (I don't need stinky instructions!). So I changed all the filters and now I have a brand new vacuum cleaner. Did I mention I have 5 cats? and I vacuum the junk they throw around, so I probably use my vacuum a little more than the average person. But now I will change the filters very often, so the vacuum should last a very long time. Thank you to this seller, GreenVacShop, for being there!
