The size I need are hard to find and I use two instead of one of each. I have been pleased with the filters and think they do great job filtering out dust particles particularly that I am allergic too
I thought I was getting top notch filter turns out it was not a HEPA filter so I'll re-look and see if you carry HEPA filters if you do I'll be ordering them in the next six months
Since ordering I get at least one unwanted email from you everyday. Ive complained, Ive unsubscribed, they keep coming. Please stop. Ill contact you when I want something.John
