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.

|1 - 4||> 10.0 Micrometers||Pollen, dust mites, cockroach debris, sanding dust, spray paint dust, textile fibers, carpet fibers||Residential window AC units|
|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|
|9 - 12||3.0 - 1.0 Micrometers||Legionella, Humidifier dust, Lead dust, Milled flour, Auto emission particulates, Nebulizer droplets||Superior residential, better commercial, hospital laboratories|

It seems the filters are slightly different than last ones received and don't seem to be as high a quality as last order. Will wait to see if they work as well.

This filter is the best I've found in its class. Clean breathable air. Very low dust distribution. Solid construction and durability. I have tried others but they pale in comparison to Honeywell Ultra Efficiency Filter CF200A 1008/U.
