  • What buyers say about Nordic Pure 20x20x1 MERV 12 Pleated AC Furnace Air Filters

    The dust trails in the upstairs and downstairs vent areas were caused by the nordic pure and I now know which areas need to be adjusted for a more even air flow.

    I counted the pleats and found 27 (the MERV 10 had 21 pleats). My heating and cooling unit is 4 years old, and does not struggle or have flow-restrictions when put into place.

    These are some of the best filters I have ever used, and they are very easy to clean.

    I use them in my garage and they work better than the real ones. For the price and the dirt in the air where I am using them, I am very impressed.

    They are made in the USA and are worth the money. Keep them changed out often, they catch everything and really clean the air good!

    Common Questions


    I am concerned that there is 1/2 the number of pleats in this as the Filtrete 1500 which should be equivalent.


    I tested this "MERV 12" filter and it only removed 5% of the particles. I replaced it with a MERV 11 (lower rating) 3M filter and it removed 75% of the particles.


    Are the filters wrapped individually to preserve the carbon?


    They come in a box and are exposed to constant airflow through the filter once in the vent.


    Is it possible that these will severely restrict the level of flow in my air handler?


    Not in my opinion, because a dirty air filter will restrict air flow and a low quality air filter will allow dirst through and get to your Air Conditioning "A" coil.


    How many filters do I get for 42.94$?12 or 6?


    You can either purchase more at a time or get on the program where they auto ship.


    What is the difference between a 20x20x1 and a 20x20x1M12-6?


    The MERV rating is 12 and can be seen at the top of the filter.
