[quote=Anonymous][quote=Anonymous]Houses are very leaky by design. As warm air rises and leaves the house, outside air is drawn in through cracks, door frames, window frames, etc. Unless you house has good filtration and air exchange, the air quality is mostly the same as the outside.[/quote] You wouldn’t want your house to be completely sealed. That would actually be more dangerous![/quote]
