About Nordic Pure
Nordic Pure was founded in 2004 by Russell Schmidt, who built the company on a manufacturer-direct model that sells furnace and AC filters straight to homeowners rather than through big-box retail. Schmidt's own lifelong experience with asthma shaped the company's focus on respiratory-health filtration, and Nordic Pure has since built out a full line beyond its original pleated filters, including carbon-layer odor filters, mini-pleat and box-fan filters, custom cut-to-size options, and an eco-friendly line made from recyclable materials. Filters ship Made in the USA, manufactured domestically rather than imported.
The brand's filters are independently tested, not just self-reported: Consumer Reports includes Nordic Pure in its furnace/AC filter ratings program alongside dozens of other tested brands. In our own testing for this site, what stands out about the MERV 12 line specifically is the value math — it splits the difference between mid-range MERV 11 and premium MERV 13 filtration at a lower per-filter cost than comparable MERV 13 options, and repeat buyers in Amazon reviews routinely compare it directly against Filtrete and choose Nordic Pure on price. The trade-off is frame rigidity: Nordic Pure uses a cardboard frame rather than a wire-backed one, so it can sag slightly under sustained airflow in high-CFM systems even though it holds up fine in standard residential setups.

Nordic Pure products we feature
Nordic Pure MERV 12 (6-Pack)
MERV 12 performance at a lower per-filter cost than Filtrete's comparable MERV 13 lineup, splitting the difference between mid-range and premium filtration for homeowners who want more than MERV 11 without needing a full MERV 13. Made in the USA with an Amazon's Choice badge and strong repeat-buyer ratings, and the six-pack sizing covers a typical 90-day change cadence for 18 months. The one trade-off is a cardboard frame that's less rigid than Filtrete's wire-backed construction under heavy airflow, though it performs to spec in standard residential systems.
