Your Healthy Home

Industry pros offer tips on improving the air we breathe

With coronavirus literally in the air, now is the time to protect your home’s atmosphere. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), indoor air is five times more polluted than the air outside, making a whole-house ventilation system critical. The following insights from experts at Aprilaire, a maker of humidifiers and purifiers, and Sterling, Virginia-based Falcon Heating & Air Conditioning will help you create a safe living environment.

  • A healthy air system has three components: fresh-air ventilation, air filtration and humidity control. Ventilation is most important; if you are ventilating your home properly, you are making it healthier.
  • New homes have tighter building envelopes, with less ventilation through cracks in windows and under doors than older homes. Owners of new homes should consider a whole-house ventilation system that brings in filtered air, evenly dispersing it via the HVAC system.
  • To improve air quality, attach a filter with a MERV (minimum efficiency reporting value) 16 rating to your HVAC system; it will trap particulates, allergens and other contaminants before they enter.
  • Every home in our region should have a humidifier and a dehumidifier; humidification in the winter is most important because drier air exacerbates respiratory disease. Relative humidity levels between 20 and 60 percent year-round are optimal.
