Filters are not only to protect your home's heating and air conditioning system, they protect you and your loved ones. Indoor air quality is a growing concern in homes, schools, and hospitals. Poor air quality can have a negative impact on your overall comfort level, as well as aggravate medical conditions such as asthma or allergies. Inadequate ventilation in the home can increase indoor pollutants such as common household dust, pet dander, pollen, dust mites, and cigarette smoke just to name a few. Filters can improve the air quality by capturing and removing these particles and pollutants, thus increasing the quality of air circulated throughout your home via your heating and air conditioning system. Be sure to change your filters as recommended to ensure the best possible air quality for your home and family.
