Do HEPA filters make AC work harder?

This high particle capture rate comes at a cost HEPA filters present more resistance to air flow than MERV filters. This means the blower on your HVAC equipment has to work harder to push air through the filter and therefore uses more energy.

Are HEPA filters bad for HVAC systems?

Though a high-efficiency air filter offers an array of advantages, it also come with certain drawbacks. HEPA filters, while very effective, are thick and dense. These qualities can substantially interfere with the airflow process of your HVAC equipment.

What are the two disadvantages of HEPA filters?

Cons: HEPA filters however cannot trap other pollutants such as gases, fumes, chemicals and odors. Can be costly when replacing filters.

Can air conditioner filter be too thick?

If you get a filter with pleats that are too thick, your filter could get dirty quickly. Thus, making your AC unit work harder than it needs to. A good benchmark to follow when considering MERV ratings is that if it’s more than 13, the pleats are most likely too thick for your filter.

Is there really a difference in HVAC air filters?

The short answer is, no, they’re not all the same. In fact, there are many different types of air filters available and choosing the right one can make a real difference in the lifespan of your HVAC system. … You see, the higher the MERV rating, the more the filter restricts air flow.

Is MERV 13 too high?

Filters within a MERV rating of 17-20 are almost never necessary in a residential home. A MERV rating of 13-16 is considered hospital level air quality, so it is unlikely your home needs any more than that.

Are HEPA air filters worth it?

HEPA filters will effectively remove most allergens, dust, pollen and mold from the air. However, they won’t remove viruses or VOCs. Mold can grow within the fibers, so it’s essential to replace it regularly every 12 to 18 months or when needed.
