MERV = 'Minimum Efficiency Reporting Value' this is used to rate the overall effectiveness of an Air Filter. Below you will find a table that measures the MERV strength and tells you the Application of each unit's effectiveness. In general an Air Filter with a higher MERV Rating is more effective and has a broader application, but most residential homes will find the best use from an air filter between the 5-12 MERV rating.

|5 - 8||10.0 - 3.0 Micrometers||Mold, spores, dust mite debris, cat and dog dander, hair spray, fabric protector, dusting aids, pudding mix||Better residential, general commercial, industrial workspaces|

It arrived on time and was the correct product. I replaced a Honeywell filter with a Honey well filter and I expect I will continue to use Honeywell filters

Reviewer: Legrand R Groves
Very good filters and recommended as per my HVAC guy. Tried other brands but the fit isn't as good and the shipping through Honeywell was outstanding. Will continue to buy from Honeywell Store.
