Hepa Filter for Hoover Windtunnel, Savvy, Empower. Replaces Hoover Part # 40140201, 42611049, 43611042. Long-life Washable and Reusable, Type 201

I borrowed a Hoover vacuum as my original vacuum stopped working properly. Since I had to clean it inside and out first, I did notice that the filter was a little dirty. I had no idea what replacing a filter would have on cleanliness of my carpets. I had assumed that it would work at 100% if I simply shook it outside to debris that I could visually see. it's like having a new vacuum! As you can see by the photo of the filter that has only been used twice, my carpets were extremely dirty. I was not kind to them at all apparently. I'm seriously considering not returning it to its owner. Lol.
