Why is ventilation so important?
Natural ventilation is obtained by simply opening a window. However, if a homeowner is paying money to cool or heat their home, they do not want to waste money on an open window. Homes have become, in effect, sealed from the outside to improve efficiency. Tips on ventilation can be seen at http://frankweglarz2015.wix.com/frank-weglarz.
Air leaks have all but been eliminated from homes with the use of weather stripping and caulk guns. Unfortunately, this means that the same air is recirculated around a home trapping pollutants and other unwanted particles into the air.
