2-Pack of Nordic Pure 16x20x4 MERV 12 Pleated Air Filters for AC and Furnace

ymmacyzuam: Love how this filter keeps the dust down. I have been purchasing these for a few years. One of my top go too for furnace filters. Also love that I do not have to replace every month. Lasts for about 3 to 4 months.

Paul Horsley: Best price without losing a high filtering ability

Terri GSatt: This filter was not the size I wanted. It was 2/8 too thin. I wanted 4” but it wasn’t so there is almost an inch space in the unit it goes in. Never had this happen before.

ShamSham: First time replacing the filter at this house. Couldn't find this size at local hardware stores. This was $18.50 when I got it. Price shot up to $65 now. Funny enough looks exactly like my old one.

Only way I could tell it was Merv 15 was marking on the box it shipped in. It's not marked anywhere on the filter itself. Would buy again if the price goes back down

Serge Gagnon: Comme il est spécifié 6-Piece, je croyais bien en recevoir 6, mais il n’y en avait que 2 dans la boîte.
Est-ce une erreur de votre part ou c’est moi qui comprends mal?
Sinon, excellent produit.

JA. EspelienJA. Espelien: Conditions: a multispeed updraft furnace with an A/C coil and an air exchanger, two cats, central vacuum, and our ductwork has been professionally cleaned every couple years. Our ductwork was originally built to take just a single 16 X 20 X 1" filter. We have our furnace blower set to run on medium low for constant circulation, medium high for heat and high for A/C. I tried everything from cheap MERV 7 Store Brand filters to washable to expensive Filtrete Allergan filters to control dust. The cheap filters and the washable filters all let too many fine particles pass through undeterred, the expensive filters began to restrict airflow dramatically after just a couple weeks. After speaking to a reputable mechanical contractor I followed their advice and modified the ductwork to take a 4" thick filter. This worked much better with a 4" filter lasting over 6 months before it started to restrict airflow. After studying the used filter it became obvious that what I needed was a prefilter to remove the coarse particles and cat hair before the main filter. I opened up my ductwork one more inch and added the washable WEB ECO filter I had previously purchased. This is a great combination I...

Joel Porter: This filter has a MERV 13 rating which they equate to an MPR rating of 2200. That means this filter is comparable in performance to the Filtrete Premium Healthy Living series air filters. The construction is comparable as well, with a cardboard scaffold on the intake side and a wire mesh scaffold on the furnace side for structural support. The pleats fit snugly against the inner cardboard frame, although they are not sealed to the cardboard frame with caulk/glue.

Note that the filter size in the title is not the actual size but the size that the furnace would generally list as the required filter size. The actual filter dimensions are given in the product information.

Finally, a word of advice on filter sizes: Always purchase the thickest filter your furnace can accept! If your furnace can accept either 1" or 2" filters, always purchase a 2" filter! Why? Because with pleated air filters the surface area of the filter media is greatly increased as you increase thickness, while the cross-sectional area remains the same. This means that air resistance is significantly reduced with larger filters sizes, leading to improved air flow and increased filter lifetime. With...
