  • What buyers say about Nordic Pure 20x20x4 MERV 12 Pleated AC Furnace Air Filters 2 Pack

    It's fine for a smoky room because the air mixes so much, even if you hold it at zero inches.

    The Nordic MERV12 didn't show any improvement in the PM 2.5 and PM.5 readings.

    He is a union trained engineer with 20 years of experience in commercial heating and cooling. I use the particle counter occasionally during California smoke season and vet my work with him.

    The meter is functioning correctly after I tested it against my HEPA filter, and the reading went from 300 to nearly zero.

    The two pack was purchased at an excellent price and was used to purify the air in my bedroom at night.

    Common Questions


    The description says box of 2, but the Tech. details says it's a package of 1 or 2.


    I got 2 in 1 Box for a great deal because our service tech wanted to charge us 40 dollars for one filter.


    Are the filters delivered in a sealed plastic or just lose in a box and are there any assurances that we won't receive a returned filter?


    The Nordic Pure shipping boz had dried out tape and both ends could be opened by anyone, but there was no branded label like you see on all their products.


    Does the filter fit a furnace?


    The Nordic Pure 20x20x5 is a 4 3/8 depth AC furnace filter.


    Will this be able to filter the smoke from forest fires across the state?


    I don't believe this will help with the smoke that gets in your house from wildfires, and you should probably get a stand alone air cleaner.


    There is no label or print on my two merv15 filters, only the dimensions are 20x20x4. Which product is this?


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