Keeping the Air Clean in your Home


Indoor air is often more than 10 times more polluted than outdoor air. Indoor air pollutants contribute to asthma as well as other respiratory conditions and diseases. Some of the indoor pollutants can include

  • Volatile organic compounds (VOCs) from off gassing building materials, paints and finishes and furnishings.
  • Other toxic chemicals emitted from cleaning products, pesticides and hazardous household supplies.
  • Mold, which grows on moist materials and surfaces.
  • Carbon monoxide and nitrogen dioxide gases, which can be released from gas-fueled combustion appliances.
  • Particulates from wood-burning fireplaces or cars running near the house.
  • Tobacco smoke.
  • Asbestos.
  • Lead.
  • Radon.

Improved ventilation will improve indoor air quality by increasing the amount of outdoor air coming into your home, diluting concentrations of indoor pollutants, and pushing stale indoor air out of the home. However, some ventilation improvements may increase energy costs unless you make design changes to your home. The third strategy, using mechanical air cleaners to filter pollutants out of your indoor air, can be used to supplement source control and ventilation but it is not recommended as the sole solution.

Filters actually become more effective in capturing and removing particulate air contaminants as they get dirtier and build up with dust. This increased effectiveness comes with a cost, however, as the pressure drop increases and less air gets through. It is a good idea to change the filter for the furnace at the start of the heating season, as the dust cake from the previous year has been sitting in the cold, dark basement throughout the summer and may have started to grow molds.

If you notice an issue with the air quality in your home, make sure to contact us so we can inspect the HVAC system for you.
