MERV 11 air filters are designed for homes with allergies and in some cases, asthma. Those with respiratory illnesses or compromised immune systems may benefit from MERV 11 air filters due to these filters being significantly more powerful than alternative MERV filters at capturing smaller particles, such as MERV 8.

The best MERV rating for your small home is likely MERV 8. This is at least a good place to start as it offers a good balance between filtration and airflow. However, it isn't the only choice. If you have allergies or other respiratory conditions, then a MERV 11 or even MERV 13 might be more beneficial for clean air and as an odor eliminator.
