We can't get around pulling in outside air, as we have a wood stove. Even closed up, there are leaks. If we run a fan blowing out upstairs to pull cool in downstairs, there is often a hint of "wood stove" smell in the living room.I run a stack starting with a standard particle filter, followed by carbon filter, with the electrostatic in the third position. Set your thermostat fan control on 'recirculation' and close the damper on the furnace intake so it's not pulling outside air.
In the house I lived in as a little girl, my parents almost killed themselves and guests with CO poisoning. The house was new (1956...?) and well built. They had a fire in the fireplace, and it sucked air back through the furnace. Everyone went to bed, feeling slightly ill, but they were all fine the next morning. They assumed they'd had a few too many drinks while they played bridge.
The next night, same thing. But someone mentioned an "odd smell," and my dad said he smelled it right then. (CO is odorless, so it was something from the furnace.) He went down into the basement and figured out the problem. From then on, whenever we had a fire in the fireplace, they'd open a window in the basement an inch.
My mom told the people who bought our house when we moved. Years later, she said she hoped that information got passed along.
This was years before smoke and CO detectors were commonplace.
