  • What buyers say about Nordic Pure 18x24x1 MERV 12 Pleated AC Furnace Air Filters 6 Pack

    I have been using these for a couple of months now and I have to say they seem to work well with our system and the air flow seems good.

    Home Depot and Lowes sell AC filters for a lot, but they are very well made and worth the money, and I will buy them from now on.

    We ordered the MERV-14 this fall because they are made in the USA, but they are usually the MERV-12.

    It is just as described, and it is easy to install.

    There are great filters, great options for number of filters per package and quick install.

    Common Questions


    Are the dimensions 17-3/8 by 23-3/8 by 1/3 or are they actually 17-"3/88" by 23"3/8 by 1/3?


    Yes, 88ths, what chu smokin?


    Is the 17.5x23.5x1 filters the same as the 17.5x23.5x1 filters? When you pull up the actual dimesions, it has the wrong dimesions listed.


    It's possible that this will help, as the Merv number is the factor that determines the rate it filters.


    How many times a year do they need to be changed?


    It depends on how much air you have moving through the filter, and if you have a fan on all the time or auto.


    The difference between the actual size and the picture is 1 inch.


    We are able to make the size you need, but you should give us a call to see if we can help you.


    I received my order in the mail and there was nothing on it or in the box to say it is a Merv 12.


    The MERV label can be found on the outside of your box. At Nordic Pure, the same filter frame is used for the large variety of filters that we manufacture.
