Levels in Homes

Particle levels in homes without smoking or other strong particle sources are the same as, or lower than, outdoor levels.

Steps to Reduce Exposure to Respirable Particles

  • Vent all furnaces to outdoors; keep doors to rest of house open when using unvented space heaters.
  • Choose properly sized woodstoves, certified to meet EPA emission standards; make certain that doors on all woodstoves fit tightly.
  • Have a trained professional inspect, clean, and tune-up central heating system (furnace, flues, and chimneys) annually.  Repair any leaks properly.
  • Change filters on central heating and cooling systems and air cleaners according to manufacturer’s directions.
