Commonly Asked Questions

Q:

What is the MERV & MPR rating of these filters?

Jana B.  asked on  Dec 13, 2013

A:

The MERV is 11. The MERV (minimum efficiency rating) is the industry standard for rating air filters and MPR is not recognized by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) as that is a 3M Filtrete rating system. FPR rating of 6 is the Home Depot proprietary rating system and these filters were certified that way also.

Q:

Will you be able to restock to offer more 18 x 24 which are currently sold out? Will they be available at another time? thanks.

Carol M.  asked on  Dec 18, 2013

A:

Thank you for your interest. Unfortunately, there was a limited quantity available for each option. As such, we do not have a rain check or wait list feature. We often try to feature popular offers again, but do not have any information to share at this point.

Q:

The Filter Effectiveness Rating of "6" is extremely low and should be disclosed within a Ratings Guideline. As advertised, this item and description are both misleading.

Keith B.  asked on  Dec 16, 2013

A:

I am sorry for the trouble and I appreciate the feedback. I will make sure to pass it along to the correct people.
