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 5-13 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||

This has been by far the best way to purchase air filters. We have 2 units at home so purchasing in bulk makes the most sense.

Peace of Mind
Greatly relieved to be able to get this particular Honeywell furnace filter. No worry about an off-brand - will it fit our not? Will it last as long as our Honeywell? The only thing the Honeywell won't do is restore power in an electrical blackout.

I have gotten a new furnace about 7 yrs. ago. I was told to change the filter every 6 months. One for the furnace & once for ac. I could not believe the dust& gunk that this filter picked up. I will continue to only use Honeywell filters.

Very high quality and when I have the furnace maintenance completed the rep is pleased with the cleanliness of the inner workings.
