Lowest price ever according to CamelCamelCamel, down from $46 one month ago.
Comparable to Filtrete MPR 1900 and Honeywell FPR 9 according to the product page on the manufacturer’s website

I did some digging and it looks like these filters have a higher pressure drop than the Filtrete and Honeywell filters they compare to. "Staff Analysis of Air Filter Pressure Drop and Air Filter Sizing (April 2018)" by California Energy Commission shows these filters at 0.37, where Filtrete was 0.18. That being said, NordicPure is certified at MERV 12, and Filtrete just claims it, so the pressure differential could be telling that same story.
Some HVAC systems may have problems with that amount of pressure drop. I don’t even know if mine will be ok with it.
