Simple Ways to Improve Indoor Air Quality in Your Home

According to the EPA, indoor air can be two to five times more polluted than outdoor air. Given that most of us spend the vast majority of our time inside, this is a statistic worth taking seriously. The good news is that there are straightforward steps you can take to significantly improve the air quality in your home.

The simplest and most impactful step is staying on top of your HVAC filter. Your air filter is the first line of defense against airborne particles. A clean, appropriately rated filter captures dust, pollen, pet dander, and other allergens before they circulate through your home. We recommend a MERV 11-13 rated filter for most homes, which balances filtration performance with airflow.

Humidity control is another critical factor, especially in New England where winter air can drop to 15-20% relative humidity indoors. Low humidity dries out mucous membranes, making you more susceptible to illness, and causes static electricity, cracked skin, and damage to wood floors and furniture. A whole-home humidifier connected to your furnace maintains comfortable humidity levels automatically.

In summer, the opposite problem can occur. High humidity creates a breeding ground for mold, dust mites, and bacteria. If your home feels clammy or you notice condensation on windows, a whole-home dehumidifier integrated with your HVAC system is far more effective and convenient than portable units.

Ventilation is often overlooked. Modern homes are built tight for energy efficiency, which is great for heating and cooling costs but can trap pollutants inside. An energy recovery ventilator, or ERV, brings in fresh outdoor air while capturing most of the energy from the outgoing air, so you get ventilation without a significant impact on your energy bills.

For households with allergies, asthma, or other respiratory concerns, a whole-home air purification system can make a dramatic difference. UV germicidal lights installed in the ductwork neutralize bacteria, viruses, and mold spores. Activated carbon filters remove chemical vapors and odors. These systems work silently and require minimal maintenance.

Finally, do not underestimate the basics. Vacuum regularly with a HEPA-equipped vacuum, keep your home clean, avoid smoking indoors, and minimize the use of harsh chemical cleaners and air fresheners that release volatile organic compounds.

If you are concerned about the air quality in your home, we offer comprehensive indoor air quality assessments. We measure particulate levels, humidity, carbon dioxide, and other factors, then recommend targeted solutions based on what we find. Serving the greater Nashua, NH and Merrimack Valley areas.
