What is the Difference Between Merv 8 and Merv 11 Air Filters?

MERV 11 air filters are more efficient than MERV 8 filters, as they can capture smaller particles. This makes them a great choice for households with pets or those looking for improved air quality.

Merv 11

filters are slightly more expensive than standard filters, but the extra efficiency is worth the cost. In some cases, a higher MERV rating is necessary.

If someone has an allergy or respiratory problem, a MERV 11 or even a MERV 13 filter should be chosen. The same applies to homes with smokers or pets, as MERV 11 air filters are better at eliminating odors. When selecting an air filter, anything below MERV 8 is unlikely to be effective. For larger spaces with an effective central air conditioning system, MERV 11 filters are the way to go.

MERV stands for Minimum Value of Efficiency Reports, and the MERV rating is the primary rating system used for air filtration. MERV 11 filters are slightly more expensive, but they can improve indoor air quality and help relieve people with respiratory problems. They are also superior to air filters with a lower MERV rating. The MERV rating system makes it easier to compare different filters.

Merv 11 can restrict airflow if you have an old HVAC system or if you haven't replaced your air filter in a while. Choose Merv 11 only if you have more than one pet and if you or a family member suffers from a serious health condition. A MERV 11 filter traps all of that, plus pet dander, smoke, smog, and air from coughs and sneezes.
