HVAC air filters are an essential part of the system. The air circulating in your home flows through them several times a day. Hence, the more effective the filter is, the cleaner air you will enjoy. Regardless, there is a limit to which it can filter, and it ranges around about one micron. Anything smaller than that will elude the filters. Therefore, you may feel the need to amp up the filtration to keep the allergens and viruses at bay. Here is where HEPA HVAC filters jump in with their exceptional ability to filter even the smallest particulate. However, should you replace HVAC air filters with HEPA ones? Here is everything you need to know.

Why Are HEPA Filters So Exceptional?

HEPA are mechanical filters that feature a tight and convoluted mesh of fibers. These are often made of fiberglass. However, it’s not the material that makes HEPA so unique; it’s their arrangements that lend these filters exceptional filter ability. The air flowing through the mesh can meander its way out. Nevertheless, particles suspended in the air are not so lucky. Hence, they get trapped in the mesh, and only purified air leaves the filter.

HEPA filters can effectively clear out 99.9% of particles with a size greater than 0.3 microns. This includes a majority of bacteria, allergens, spores, and viruses. Therefore, HEPA is primarily used in hospitals and nuclear facilities.

What Kind Of Filters Does Your HVAC Unit have?

Most HVAC filters have a MERV rating ranging from 8 to 10. This means they can easily filter out larger particles, but their efficiency droops when dealing with smaller particles. Nevertheless, they suffice the majority of your household needs. Thus, you may not need to replace them unless someone in your family has allergies or asthma. In such scenarios, or to avoid viruses like Covid-19, you may consider upgrading HVAC air filters in your home.

Should You Opt For a HEPA HVAC Filter?

There is no problem in replacing HVAC air filters with HEPA ones. However, while you enjoy safer air, the HVAC system will suffer from restrained airflow. Airflow restrictions will cause operating costs to rise. Therefore, generally, HEPA HVAC filters cost more than other ones. On the other hand, you may need to replace these filters more often because they get clogged frequently due to the intricate filtering process. As a result, you should expect to spend more when you use HEPA HVAC filters. It’s better to use standalone HEPA filters to counter performance issues.

Suppose you have decided to purchase HEPA filters; try to stay away from brands trying to cash in the fad. Most brands will advertise their filters with the words, “HEPA like” these less efficient filters aren’t HEPA. Hence, always purchase after careful inspection and from trustworthy dealers.
