Review on Fette Filter Pre Filters Compatible 920640 01 by Alexandria Richmond

I replaced my grossly smelly OEM filters with these today and they work. I don't notice any strange noises as reported by some users. They fit perfectly and are as easy to install as genuine Dyson products. Will they last as long? Honestly, given my dog and two cats, it's probably better for me if they don't. But I have two sets of spare parts, so it will last a long time.
