High-efficiency HVAC Filters – Pros and Cons

High-efficiency HVAC filters may be something you have heard a little about, but aren’t familiar with. Perhaps a co-worker or friend has mentioned how a high-efficiency filter might improve indoor air quality, and now you’re curious about how they work, and whether it is something you should consider. Our Ann Arbor HVAC professionals are sharing the pros and cons of high-efficiency filters so that you can make a more informed decision.

Regular HVAC Filters vs. High-efficiency

Designed to protect the components of your HVAC system from large dust particles and other debris, regular filters are generally about one inch thick. Most homeowners think these filters work to improve the quality of indoor air substantially. However, this isn’t the case. A regular filter removes the big particles from the air, but not the pollen and small dust particles that affect not only the air quality inside your home but the health of your family members.

High-efficiency filters are designed to improve indoor air quality by removing not only small dust particles but mold spores, tobacco smoke, viruses, and other contaminants. Your family enjoys a cleaner, healthier indoor air.

Most Important Benefits of High-efficiency Filters

High-efficiency HVAC filters offer genuine health benefits, particularly for those with asthma, COPD, allergies, or other respiratory health issues. These benefits include:

  • Fresher smelling air
  • Fewer dust particles in the air
  • Allergen reduction (pollen, mold, etc.)
  • Reduction in respiratory irritants
  • HVAC components and ducts remain cleaner

Before You Make the Switch

It’s tempting after reading about the benefits to want to switch to a high-efficiency HVAC filter right away. Before you do, it’s essential to know that the wrong filter can wreak havoc with your system if it reduces the flow of air. The air filter must be appropriate for your HVAC system, and it’s recommended you speak with a professional to ensure your system will accommodate the upgrade.

There is a wide array of high-efficiency filters available today, however not all companies who manufacture these filters are knowledgeable in regards to modern cooling/heating equipment and airflow requirements. Switching from a regular filter to one that is high-efficiency without ensuring proper airflow could put the lifespan and dependability of your system at risk. A highly efficient air filter could restrict airflow, causing compressor failure, overheating, or frozen coils depending on operating mode (cooling/heating).

The best thing you can do is to work with one of our heating and cooling technicians who can perform an airflow test to help determine the best type of filter for your system.
