Choosing Between Air Filtration and Air CleaningWhen you think about indoor air quality (IAQ) problems, you may be reminded of household dust, germs and allergens, and how these contaminants impact the health of people in your home. Even if no one in your home suffers from respiratory ailments, such as allergies or asthma, you may still be aware of how good air filtration helps your HVAC system run better and saves you energy.

In addition to using a good furnace filter, using an air cleaner enhances IAQ by removing microscopic particles, odors and microorganisms from your home that most filters aren’t designed to capture. If you aren’t sure which IAQ strategy makes sense for your home, whether it’s using a high-quality filter, an air cleaner, or both, read on to find out.

Air Filters

Many vital components of your HVAC system are exposed to airflow. If contaminants in the airflow aren’t removed, they will accumulate on HVAC surfaces and cause problems with HVAC functionality and efficiency. Your furnace filter’s primary purpose is to protect the blower, heat exchanger, evaporator coil, ductwork and drainage from debris and mold growth.

Air Cleaners

Whole-home air cleaners are installed inside the HVAC system, and are very effective at enhancing IAQ throughout your home. The differences between various types of air cleaners are the technologies used.

  • HEPA (High Efficiency Particulate Air) filters are very dense media that capture contaminants by impaction.
  • UV lights use ultraviolet bulbs to destroy microorganisms, such as mold, germs and viruses.
  • Electronic air cleaners capture particles and microorganisms using electrostatic attraction. Electronic and UV air cleaners won’t cause your HVAC blower to use more energy by impeding airflow.

Air Filter or Air Cleaner?

When you’re considering enhancing your home’s air quality for health reasons, you’ll want to consider using a combination of a high-efficiency filter and an air cleaner for best results. If you aren’t too concerned about allergens, germs and mold in your home, you should still choose a high-quality filter to protect HVAC components.
