Most homeowners rarely, if ever, think about their home’s indoor air quality. But it may be time to start. According to the Environmental Protection Agency (EPA), the air inside the average American household is up to five times more polluted than the air outside. Pollutants commonly found in the home consist of bioaerosols and particles such as dust, pollen, viruses, bacteria and even potentially harmful chemicals or gases. These airborne particles can lead to an increase in allergy and asthma symptoms, sickness or unpleasant odors.
The main source of the problem could be coming from your HVAC unit. Regularly changing your HVAC unit’s air filter is crucial in the fight against indoor air pollutants. Most HVAC or furnace filters are disposable and designed to trap these pollutants or other unwanted particles. Homeowners should change air filters every three months, but other factors could warrant changing the filter sooner. Household pets, large families, indoor smoke or living near a heavily wooded area can all lead to an increase in dander. Homeowners with any of these situations should check their air filter monthly to prevent major buildup of pollutants. Not only will a fresh air filter cut down on unwanted indoor particles, but also ensure that your furnace receives optimal airflow and runs smoothly.
