Americans spend about 90% of their time indoors, where air can be 2-5 times more polluted than outdoor air. Here are seven practical ways to improve the air quality in your home.
1. Upgrade Your HVAC Filter
Your HVAC filter is your home's primary air cleaner. Consider upgrading to a higher MERV-rated filter (MERV 11-13) to capture smaller particles including pollen, mold spores, and some bacteria.
2. Control Humidity Levels
Ideal indoor humidity is between 30-50%. Too high promotes mold and dust mites; too low causes dry skin and respiratory irritation. A whole-home humidifier or dehumidifier integrated with your HVAC system provides consistent control.
3. Install an Air Purifier
Portable air purifiers help, but whole-home air purification systems work with your HVAC to clean air throughout your entire house. UV light purifiers can kill bacteria and viruses, while HEPA filters capture microscopic particles.
4. Ensure Proper Ventilation
Fresh air exchange is crucial. Make sure bathroom and kitchen exhaust fans vent outside, not into attics. Consider an energy recovery ventilator (ERV) to bring in fresh air without losing heating/cooling efficiency.
5. Keep It Clean
Regular cleaning reduces airborne particles. Vacuum with a HEPA-filter vacuum weekly, dust with damp cloths, and wash bedding in hot water. Don't forget to clean air registers and returns.
6. Reduce Chemical Pollutants
Household products like cleaning supplies, paints, and air fresheners can release volatile organic compounds (VOCs). Choose low-VOC products when possible and ensure good ventilation when using chemicals.
7. Schedule Regular HVAC Maintenance
Professional HVAC maintenance includes cleaning coils, checking ductwork, and ensuring your system operates efficiently. Clean systems circulate cleaner air throughout your home.
