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.

It arrived without a hiccup and installed without a problem. Before ordering, make sure you buy the right size for your system. This is my second time ordering, and I will do so again next year.
I love the Honeywell filters. The best available. I recently moved in a new location and wanted to replace the filter in there with a Honeywell filter as I HAVE VERY BAD ALERGIES. I HONESTLY WAS STUNNED TO SEE IN JUST A COUPLE DAYS HOW BLACK AND DIRTY THAT FILTER WAS IN SUCH A SHORT TIME. A GREAT home change in protecting your health.
Good quality for the the money.
We switched from the generic filters that came with the new build and switched to these. I'm glad I did. Filters so much more and keeps the house without odors. I would never use a different air filter ever again.
No complaints
The filter does a good job in a city dwelling. It's easy to change. The delivery was faster than estimated which was great.
My filters were delivered to the door. Correct and convenient.
Not the first time that I have gotten these. Great filtration and I am always amazed at what they catch. I change them every three months and plan to buy them again.
I have always used these filters and I highly recommend them. First time using the ultra 13 though, very confident they keep a home atmosphere clean.
Great job. I well order again.
