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|

I love to order my air filters from here -They are slightly cheaper and I don't have to run out every time I need to change it. It also helps keep my rotations regular and that over time will extend the lifetime of my HVAC Unit!

I am pleased that I can order in a larger quantity, cheaper than I get in the store. I have a cat and I have to change my filter once a month. It's nice to have a constant backup.

I ordered six each of this size filters for my HVAC system. They arrived quickly and just as ordered. They have a reputation for the being the best filters and I agree.

Since purchasing the Honeywell Filters several years ago, our home has less dust and my family has had fewer health issues. Even during the allergy season the associated symptoms are far less than we've experienced in the past.

Better Air and Savings too!
You can trust the name and trust the merv rating, a trustworthy industry standard unlike what's offered at big box stores. Combined with added savings, I am so far very satisfied with my purchase.

This is the second time I've ordered a set of 6 filters for my HVAC from the Honeywell Store. It's a hard-to-find size, so very easy and convenient to order online. It's also a great price. Much easier than making special trips to the local shops, only to find they don't carry this size.
