Nordic Pure20x25x4 (19_1/2 x 24_1/2 x 3_5/8) Pleated MERV 12 Air Filters 2 Pack

Bought these for my furnace to replace the original Honeywell 20x25 version (19.9 x 24.75 x 4.375 inches), these are about 3/4" thinner so its sloppy in the groove, but I was able to make it work (Nordic Actual = 19.375x24.5x3.675) . I've used Nordic for other sizes that are 1" thick in the return vents and they are great -- this is a good quality filter, just a tad thinner and shorter than what my furnace needs in terms of a 20x25x4.

I recently purchased the Nordic Pure 20x25x4 air filters, and I’m really happy with their performance. They fit perfectly in my HVAC system and seem to do a great job filtering out dust, allergens, and pet hair. My air feels fresher, and the filter is holding up well after a month of use, with no noticeable clogging or reduced airflow.The build quality is solid, and I love that these filters are made with a higher MERV rating, which helps capture more particles. They’re easy to install and don’t have any chemical smell like some cheaper filters.The only thing to note is to double-check your measurements—make sure they’re the exact size your system requires, as the fit is very specific. Overall, I’m happy with these filters and would definitely recommend them for improving air quality!

These are really good but I ordered the wrong size! I can’t crawl under my house to change the filters, so by the time my friend was able to, the return window was gone! If the company is reading this will they help me? Perhaps exchange them for 16x20x4 please? Thanks

As you'll see if you are trying to decide on a furnace filter that many measure different than their model number suggests. These measure smaller than the expected 20 x 25 x 2" which is my bad for not noticing before ordering. It is smaller so it easily fits into a 20 x 25 x 2" slot and still seals around the edges but just barely.These seem to have a few less pleats than more expensive brands and a bit thinner cardboard frame but I have not had any problems yet. I will update if it looks bad after a few months, otherwise, knowing that I saved some money, I am satisfied with these filters so far.

Made in USA, better quality than big box, and great price.

Installed in my HVAC , fit well and work well.

The air will go right around this trash air "filter". It's too small in every dimension! It won't even stay in place when the fan kicks on.I've owned this house and this HVAC system for 10 years and have used a few different brands of air filters. They all worked until I got Nordic Pure. It's not even close to the right size! It says 20x25x4 but it's so much smaller than every other filter. Why would Amazon even sell this? You would never find these in a local brick and mortar store.

Excellent quality, fit and air flow. No gaps for air leaks as sizing is accurate. Using subscription ship reminds you to change your filter.
