I've been told when I look to buy an air cleaner to check the MERV but don't know what that is. MERV is an acronym which stands for "Minimum Efficiency Reporting Value" . The MERV rating is the standard method for comparing the efficiency of an air filter. The higher the MERV rating, the better the filter is at removing particles from the air.
The MERV scale ranges from 1 (least efficient) to 16 (most efficient). Filters with higher ratings not only remove more particles from the air, they also remove smaller particles. A typical fiberglass furnace filter might be rated from 1 to 4 on the MERV scale. High efficiency filters would have a MERV of 10 to 16. Aprilaire whole home air cleaners fit into the 10 to 16 scale. The models 2210/2410 are MERV 10. The models 4200/4400 are MERV 13. The model 5000 is equivalent to a MERV 16.
