People spend up to 93% of their time indoors where – surprisingly – air pollution can be up to 10 times greater than outdoor levels.
This poor indoor air quality results from reduced natural ventilation – a phenomenon that has developed in recent years from tighter, more energy efficient building construction. Indoor air consists of mostly invisible gases and particulates, including many which can be characterized as pollutants. These pollutants include many substances taken for granted, such as cooking smoke and grease, aerosol sprays, tobacco smoke, animal dander, ashes, human skin flakes, household cleansers, carbon dioxide, viruses, bacteria, pollen, and fungi.
Fortunately, there is a way to have cleaner, fresher air, and that’s by using air filters in your air conditioning and/or heating system.
