Keeping Ventilated

It's easy to overlook indoor air quality. Your home should filter and circulate clean, fresh air to promote better respiratory health. Proper ventilation can reduce your exposure to allergens, mold, carbon monoxide, and more.

Quick tips to keep your home well-ventilated:

  1. Use kitchen and bath exhaust fans when cooking and bathing.
  2. Do the toilet paper test to make sure the exhaust works properly.
  3. Change air filters regularly on heating/cooling units.
  4. Clean dryer lint traps.
  5. For fireplaces, make sure the flue is clear and open when a fire is lit.
