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.

|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|

The only thing I wish is that you could buy a higher MERV in this product.

How much can one say about a filter? This was something that my dad always took care of, and he up and died this past year, leaving me with the responsibility. As far as the ordering and the quality of the product, I would have to say a big 5 stars across the board.

My filters have always measured 20X24X4 so when I ordered these filters and the description changed to “6”, I panicked and contacted Customer Service to cancel the order. They assured me these were correct and I was thrilled to find that they are. Thank you!

Worth waiting for the BEST!
Similar to toilet paper, Covid left all furnace air filters unavailable. With dogs in our home, we continued to vacuum and clean our over 1 year old Honeywell air filter until YOU contacted us that the filters we needed were available! We immediately purchased the last 2 you had available. They quickly arrived and we gave them a good home. Worth the wait. These are high quality and the very best furnace air filters available. Thank YOU!
