What you can’t see, can hurt you. According to the Environmental Protection Agency (EPA) indoor air quality could be two to five times more polluted than outdoor air. You might find that shocking when we think of pollen, smoke, car emissions, and other pollutants that float around outside, but building materials, cleaning chemicals, candle smoke, mold spores and other common household pollutants are sealed inside.
Without proper ventilation and filtration harmful indoor air stays sealed inside and can cause negative health effects soon after exposure or even years later. Symptoms may include irritation of the eyes, nose, and throat, dizziness, headaches, fatigue, or enhanced allergies and asthma. According to several studies people spend approximately 90% of their time indoors. Improperly or inadequately maintained heating and cooling system filters may be one cause of indoor air quality problems. Clogged air filters prevent air from circulating through your HVAC system impeding the collection of harmful pollutants. Changing your indoor air filter regularly is one simple way to increase airflow, minimize indoor air pollution and keep your family healthy.
