Tips for Achieving a Healthier Home With Better Indoor Air Quality

Tips for Achieving a Healthier Home With Better Indoor Air QualityA case can be made that indoor air quality has a greater impact on health than conditions in the great outdoors. About 70 percent of the approximately 20,000 breaths you take every day are inside your own home. Unfortunately, the impetus for greater energy efficiency over recent decades has led to air-tight home construction methods that tend to concentrate indoor pollutants, exacerbating air quality issues. Today, the EPA reports that the environment in many homes is as much as 3 to 5 times more polluted than outdoor air.  

Here’s what you can do to reduce the daily dose of pollutants by improving home indoor air quality:


  • Natural ventilation methods include simply opening screened windows and doors when weather permits Opening windows on opposite sides of the house promotes flow-through of fresh air.
  • Spot ventilation refers to mechanical methods such as kitchen and bathroom ventilation fans that exhaust to the roof. These remove accumulating pollutants from cooking and cleaning as well as excess humidity.
  • Whole-house ventilation includes a high-volume central attic fan to flush the premises rapidly with fresh air, particularly during cool nights and mornings.
  • Heat recovery ventilators incorporate dedicated ductwork to continuously induct fresh outdoor air and exhaust stale indoor air in balanced volume, while recovering heat from the exhaust airstream to minimize energy loss.


Switch out your air filter for a higher-efficiency, pleated version with MERV (minimum efficiency reporting value) ratings of 4 to 8. This will reduce airborne particles down to the range of 3 microns, including dust, pollen and other irritants.


Ask your HVAC contractor about installing ultraviolet lamps inside ductwork to sanitize circulating air. Continuous exposure to UV light neutralizes toxic airborne microorganisms including mold spores, viruses and bacteria.


Install CO detectors on every floor of the home in the vicinity of sleeping areas. To reduce potential hazard from CO gas, schedule annual maintenance by a qualified HVAC technician for combustion-related appliances such as a gas-fired furnace, water heater and stoves.
