3 Ways to Maintain Healthy Indoor Air Throughout the Winter

With the temperatures dropping outside, you’re less likely to open the windows in your Wilmington, North Carolina, home and let in the fresh air. So how can you keep your indoor air fresh when it’s too cold to let the outside air in? Keep reading to learn about three practical ways you can maintain healthy indoor air this winter without having to open a window.

Change the Filters

Dust, dander, and other dirty air particles floating around your indoor air can contribute to upper respiratory irritation. Fortunately, your HVAC system has a built-in air filter to help remove those dirty particles from the air as it circulates. However, air filters need regular replacements so they can keep catching the dust that passes through. Plan on checking your filter every month in the winter and changing it out when it starts getting full to help maintain healthy indoor air.

Install an Air Purifier

While air filters remove dirty air particles, air purifiers are designed to trap and kill those smaller air pollutants in indoor air, such as bacteria and viruses. Air purifiers are often installed directly in your HVAC system’s return line, so the air that gets heated and pushed throughout your home is clean and healthy. If you want healthy air throughout the winter, consider installing an air purifier in your HVAC system.

Use an Energy Recovery Ventilator

Part of what causes stale air in your home during the winter is a lack of ventilation. An energy recovery ventilator (ERV) is especially useful when the outdoor air is polluted or it’s too cold to open a window. As an ERV brings in outdoor air, the outgoing stale air transfers most of its heat to the cold fresh air before it gets filtered and pushed throughout your home. Therefore, you can ventilate your indoor air, improve indoor air quality, and save on heating costs.
