I love the wind tunnel but I've found it "gasps" when I use it. I ran it for a second with no filter and the audio was gone. A sure sign that it's time for a new pair of filters. The washable filter is washable, just make sure it's completely dry before putting it back in! These replacement filters are perfect for my vacuum and I couldn't tell if they were from a third party and not directly from the vacuum. Make no mistake: you are perfect.
