Nordic Pure 20x20x5 (19_5/8 x 19_7/8 x 4_3/8) Honeywell/Lennox Replacement MERV 12 Air Filters 2 Pack

I had to return it because I have a 1” grille in the opening and the filter would not fit. It wasn’t the fault of the product, just mine.

Fits right against a 20” box fan. I run it 8 hrs a day on a timer in my basement. It’s much quieter and lower power than running the furnace blower. The filter seems to be working well.

This filter is of EXCELLENT and SUPERIOR quality compared to the filters that my HVAC company provides for system maintenance. I had always trusted my installer and maintenance company to replace with the best filters, and they charged me over $40 for each filter (two units means two filters for every change out). Fast forward to August 2023, I decided to try out these filters after reading some reviews. I bought a set of two Nordic Filters for around $50. I was able to have them shipped in an Amazon box at no extra charge to prevent crushing of the filter boxes. To my amazement, each filter is encased in one of the sturdiest, non-crushable boxes I have seen in a very long time! Way to go Nordic Pure on protection for your product and thank you Amazon for extra shipping protection. These filters are of such high quality that I now have them on Subscribe & Save through Amazon. I hope I can stay locked in at this exceptional price.

Somewhat unhappy that the outer box was undamaged, but both filters inside had minor damage. They were not in the same locations on each filter but part of the outer box frames were mashed in or bent. Still useable but if they come like that again, I'll look elsewhere.

These filters are perfect with a good price

Fits our AHU, works great

This was an "experiment" to test out a higher quality filter in our home HVAC system. I was somewhat concerned that increasing from a Merv 8 to Merv 12 would not be noticeable and create more back-pressure in our system. Surprise to me..., this filter made a noticeable improvement by reducing the dust, significantly, compared to the Merv 8 (Honeywell) we have used for the past 3 years. We elected to remove our Honeywell Electrostatic Filter Cartridges and replace them with a 4x20 filter (Honeywell size), after 6 years of Electrostatic . We had to many issues and poor performance from the Electrostatic Unit (it might have been killing germs??? but, it didn't remove typical dust or smells!!). We noticed a slight improvement with the original switch to a Merv 8 filter, made by Honeywell for a replacement. After 3 years and 9 cartridge filters (approx. 3 to 5 months on each), we wanted more... Our "system" is rated to handle up to a Merv 13 filter and not harm the unit, some are not (you will want to check that for your system). The issue was $$$ vs. performance vs. longevity and the challenge of every manufacture saying "ours is the best." I got lucky...This filter is worth the extra money, last longer (6 months easily for our usage, probably could go 8 or 10 with no concerns.), and cured the dust and smell issues. The extra cost is worth the expense if considering a 3 year usage pattern, my math, and the overall improvement. Hope this helps you.

Good option to replace my more expensive, compatible filter.. These are very wide so they aren't available in most big box stores and AC companies want a fortune. This worked out well.

This is the size of our furnace filter and it has worn a lot so this new one will replace it

Great fit. Air smells better.

This was big improvement on the filters I was using. They are expensive but work well
