Which Filter Is Best? [HEPA vs. MERV]

Homeowners across the great state of Texas have heard of the benefits of air filters for their space. But how well do you know about your different options?

What Is HEPA?

HEPA filters, or High Efficiency Particulate Air filters, are a certified filter design with fibers arranged in a specific formation to capture as high as 99.97% of airborne contaminates 0.3 microns or larger. This term is used loosely by some filtration brands, so be mindful when shopping for a HEPA filter. Look for the True HEPA certification as opposed to HEPA type.

True HEPA filters cannot be washed or cleaned and must be replaced instead. On the other hand, HEPA type filters can be washable and are rated to block 90-99% of airborne contaminants – but not all germs and bacteria. True HEPA filters can be found in air purification systems, air conditioners and vacuum cleaners.

What Is MERV?

MERV stands for minimum efficiency reporting value, measured by a rating of 1-20. Unlike HEPA filters, MERV refers to the efficiency of the filter, rather than its design. Ratings between 16-20 work well in places like hospitals and nuclear facilities but aren’t suitable for home use. Filters with a MERV rating between 8-13 are suitable for residential use. If your filter has a MERV rating of 5 or below, it can still trap particulates like dust, insect debris and carpet fibers, but a rating between 8-13 is recommended.

MERV ratings determine the effectiveness of your filter in eliminating airborne toxins and pollutants. MERV filters are suitable for all types of central ACs and heaters, with specific ratings varying between models.

Trusted IAQ Solutions In College Station

The reason why your filter choice matters is that an air filter directly affects your home’s IAQ – indoor air quality. An ineffective or poorly-made filter isn’t going to trap a large number of contaminants, while filters with very high ratings can overwork your AC. It’s important to find the balance between clean indoor air and energy efficiency.
