Is MERV 11 a good filter?
Is MERV 11 a good filter?
The MERV 11 filter is best for pet owners and people who live with certain health conditions, such as mild allergies and mild asthma. It offers more filtration for cleaner air than the MERV 8 but doesn’t filter as much as the MERV 13 (the highest option suggested for residential use).
How often should you change a MERV 11 furnace filter?
The MERV rating also determines generally how often to change your furnace filter. You must have a clean filter, MERV 8 filters should be changed every 3-4 months, MERV 10 & 11 filters every 6 months and it’s a good idea to change MERV 16 filters every year.

What’s the difference between MERV 10 and MERV 11?
A MERV 9 will trap less than 50% of particles sized 1.0-3.0 microns, MERV 10 will stop up to 64%, MERV 11 will get up to 79%, and MERV 12 is capable of catching up to 89%.
