HEPA filters can be confusing. You probably know they filter air really well, but not much else. There’s a lot of mixed info online too. As HVAC experts, we want to clear up any confusion so you can get the right HEPA filter for your system.

The main things to know are:

  • HEPA stands for “high-efficiency particulate air.” These filters trap tiny particles like dust, pollen, and smoke.
  • To qualify as HEPA, the filter must remove at least 99.97% of particles over 0.3 microns in size.
  • HEPA filters are denser than normal filters. This extra density catches more particles but also restricts air flow.
  • Using a true HEPA filter means changing your filter more often. They clog faster than regular filters.
  • HEPA filters cost more than basic filters, but can really improve indoor air quality. They trap a lot of irritants.
  • Make sure to get the right HEPA filter size for your HVAC system. Check the manual or ask us.

So in short, HEPA filters are top-of-the-line when it comes to trapping particles. Just be ready to change them regularly and match the size to your system. Let us know if you have any other questions!


For a filter to really be called “HEPA,” it must catch 99.97% of particles that are 0.03 microns or larger.

HEPA filters go in air purifiers to remove particulates. But purifiers often have other filters too, like carbon pre-filters. These help kill bacteria, remove odors, and catch more particles. Some purifiers also use UV light.

HEPA filters are too dense to go directly into a furnace’s airflow. They restrict too much. So they often have a bypass setup. Some HEPA filters attach outside the ducts and have an internal bypass.

Always check with an HVAC pro to be sure you have a true HEPA filter.

HEPA filters are great for removing tiny particles and improving indoor air for your family. But you need the right setup.

HEPA filters catch tiny particles like bacteria and viruses. But they don’t protect your HVAC equipment from dust and dirt.

For that, use a good quality main furnace filter (MERV 10-13). This will catch larger particles and protect your system.

Using a high-quality main filter means you won’t have to replace the HEPA filter as often. Those get expensive.

If worried about cost, just use the HEPA filter during allergy season. Use the regular filter for the rest of the year.

But some filters can damage your furnace by blocking airflow. Always ask your HVAC pro before switching filter types or brands.

The main points:

  • Use a HEPA filter to remove tiny particles from the air.
  • Install a quality main filter to protect your HVAC equipment.
  • Consider only using the HEPA filter during allergy season to save money.
  • Check with your HVAC professional before changing furnace filters. The wrong one can damage your system.


Using HEPA filters at home can really help make the air inside your house cleaner and healthier to breathe. HEPA filters are great at trapping all the tiny bits of dust, pollen, and other stuff floating in the air that you can’t see. So they help get rid of all those little particles that might bother your nose, throat, or lungs if you have allergies or asthma. With cleaner air to breathe every day, you’ll probably notice less allergy symptoms and breathing issues. It’s an easy way to improve the quality of the air in your home and make it nicer for your body.



Don’t just change your HEPA filter on a schedule – check it regularly to see if it needs replacing. Take a look at the filter and see how dusty or clogged up it is. Also keep an eye on dust levels in your home. For most people, the main filter probably needs changing every 4-6 months. But the HEPA filter itself could last a whole year before it needs changing. If you have pets, allergies, or other issues, you may need to change filters more often. A good rule of thumb is that it’s time to swap the filter if you can’t see light through it anymore.

Improving your indoor air can really make your home more comfortable. If you have any other questions about HEPA filters and how they can help your family breathe easier, give us a call at InversionMagazine! We’d be happy to help out and provide more information.
