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.
|MERV RATING||MIN. PARTICLE SIZE||TYPICAL CONTROLLED CONTAMINANT||TYPICAL APPLICATIONS|
|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|
|13 - 16||1.0 - 0.3 Micrometers||Bacteria, droplet nuclei (sneeze), cooking oil, most smoke and insecticide dust, most face powder, most paint pigments||Hospital & general surgery|
|17 - 20||< 0.3 Micrometers||Virus, carbon dust, sea salt, smoke||Electronics & pharmaceutical manufacturing cleanroom|

Buying directly from Honeywell was much cheaper than Home Depot or Amazon. Highly recommend.

I ordered six of these filters on line. They arrived quickly and in perfect shape. I will order more filters from Honeywell when the time comes.

I was initially concerned that the filters would get damaged in shipment, but they arrived in perfect condition. I did order six, so they were in a larger box. I ordered on Sunday and they arrived on Wednesday. Filter performance is fine so far.

How convenient it is to purchase these efficient filters! They are easy to change and I was even sent a reminder email to reorder just before my supply ran out.
