I'm finished framing the basement of our new home. It has only 4 windows, only two of which will end up in the family room, the other 2 in the furnace room. There is also a bathroom and another bedroom, but there are no windows there. I figure that over time they will get to smell funky, so, while the walls are opened up I'm trying to figure out a way to vent air in and out of these rooms. Our heating system is hot water so, running ductwork is not an option. The downstairs will have a suspended ceiling.
I'm thinking of using large flexible hoses with a small quiet fan somewhere in the middle going to and from two vents on the outside (similar to dryer hose vents) with a switch that can turn the fan on/off. But in wintertime this will allow cold air into the room.
What about a stand-alone room air purifier? Is there such a thing?
Ideas? Thanks.
