Currently I have a 80% oil furnace and I'm upgrading to a 94% Bryant Plus 90I
The furnace is located in the laundry room with a gas dryer and 2 dogs. My air filter that I currently have just slides in and doesn't have any door. So I tape it shut. Being that oil furnace gets the combustion air from the inside, I have a feeling it's pulling in dog dander and dryer lint, regardless if I bath the dogs and don't see visible lint in the dryer room.
Will the new furnace cut down on the dust if it's pulling air from the outside and not the dogs room. I do realize it's also receiving air from the returns and it's going to circulate the dust we have already and create our selfs.
Will I see a difference moving from the pleated (600 Rated) 3M special to the thicker MERV 8 or 10 filter?
