What is an air filter?

Air filters are cleaning devices that capture unwanted, sometimes harmful pollutants from the air circulating in your home. They are essential components of forced-air HVAC (heating, ventilation and air conditioning) systems. With indoor air pollution as one of the top five environmental health risks, it is important that homes have adequate ventilation and clean air to help control or eliminate the potentially harmful elements.

Air filters ultimately help filter out allergens, pet dander, dust, fumes, odors, and other small particles that can affect the lungs. Additionally, air filters should be routinely monitored and changed to maximize comfort for those indoors.
