How Your HVAC System Cleans Your Indoor Air

The air in your home contains numerous particles, microbes, and molecules, including dust, pollen, animal dander, mold spores, viruses, bacteria, odors, and volatile organic compounds. Together, these particles can contribute to respiratory irritation, including allergy and asthma flare-ups, as well as increase your family’s risk of contracting illnesses such as colds and flu. Your HVAC system is designed to screen out some airborne particles as it functions by pulling air through a furnace filter, which is located just behind the air intake grille in your home. However, this furnace filter has its limits; keep reading to find out more about how your HVAC system cleans your indoor air, and how the addition of a whole-home air cleaner could improve the breathability and clarity of your indoor air in Orlando, FL.

Managing Your Furnace Filter

All forced-air HVAC systems incorporate a passive furnace filter. The purpose of this filter is largely to screen out particulate matter as air is drawn into your heating and cooling system for treatment, which protects your HVAC appliances from dirt and dust buildup that robs the system of efficiency and decreases component longevity. While this process does remove some particles from the air you breathe as well, smaller particles can easily slip through the mesh framework of the filter and continue to circulate through your home. Over time, all furnace filters will become clogged by the particles they pick up, and must be replaced every one to three months to remain effective. While furnace filters are manufactured with various MERV ratings specifying the particle size they pick up, installing a furnace filter with too high a rating can affect airflow through your HVAC system, leading to increased strain and higher energy bills.

Adding a Whole-Home Air Cleaner

Whole-home air cleaners are an excellent complement to your furnace filter. These air cleaners screen out a higher percentage of particles by actively attracting airborne contaminants to the filter via an electrical charge. While some particles may still be too small for the filter to catch, they will gain a charge when they pass through the filter’s charged medium. As these particles move through your air, their residual charge attracts them to other particles, causing clumps. These clumps grow until they are either captured by your passive furnace filter or caught in the whole-home air cleaner’s medium. Whole-home air cleaners thus augment the function of your furnace filter without compromising airflow. These products allow for the removal of a greater number and variety of airborne particles from your air, drastically improving its breathability and reducing the incidence of asthma, allergies, and other respiratory discomfort among your family members. Most whole-home air cleaners don’t require a replaceable medium, but instead should be cleaned every few months for maximum efficiency.
