I don’t even have the specs on mine… don’t feel like climbing into the attic to find the model number… but I have two 20x20 returns each with its own filter so that’s a lot of surface area… I’m gonna take my chances… I don’t imagine fresh 13s are any harder to draw through than the filthy clogged 8s that most furnaces in the country probably are using

Well we finally got the promised rain, and we are now in Poor range for fine particulates. Never been so happy to get back to Poor. We can take a walk outside now and not feel like we were pulling hard on a cigar for 30 minurtes. Passed a bar earlier this week and the smokers were sitting outside going to town on their cigarettes and I was thinking, wow the cigarettes might actually be healthier than the air. But not anymore.
