  Perfect fit replacement for a Honeywell 20x25x4 filter, great value, works well

  If you are looking for a replacement / alternative for a 20x20x4 Honeywell Model # FC100A1037, this is it. It is confusing, because you would think you would need the Nordic Pure 20x20x4, but NO, that filter is 3 5/8" thick whereas the Honeywell is 4 3/8" thick. Instead, you need this, the Nordic Pure 20x20x5 - it has the same dimensions: 19 7/8 x 24 7/8 x 4 3/8, as the Honeywell. Even though the product page clearly shows the actual dimensions of this filter, I feel labeling it as a 20 x 25 x 4 is misleading, or at the very least, makes it easy for average homeowners ( vs. HVAC technicians) to end up ordering the wrong product. Also, out of the five times I have ordered Nordic Pure filters, three times, (though not this time) the shipping box, and the filters within, have been significantly damaged. Yes, Amazon / Nordic Pure "made it right," but still, it was a hassle. Those issues aside, these are good filters, offered at a good price, which is why I keep ordering them. The funny thing is, my other air handler's stated filter size is 20x20x4, but for it, the standard Honeywell filter is too thick, and the Nordic Pure fits just right. Go figure...

  Works fine.

  My HVAC guy says that these are good quality filters. I inspected the 6 month old ones he took out. They caught large and small dust, dog hair, small insects. Read more

  Great Filters at a Reasonable Price...

  I've been buying Nordic Pure filters (MIRV 13 - 20x25x5 +carbon) for our home HVAC unit for the last 10 years at least. They are not the cheapest filters, but for the size we need there is not much choice if you actually want a high quality filter. These filters are well made with high quality components that last. The size is just right for our unit and just slip in to the slot easily. I "try" to replace them every 3 months or so, one time I went 5 months :( the filter was filthy but still working. I have allergies so I get the +carbon option to help clean more crud out of the air. Recommend? Definitely! Read moreVer másVer menos

  Nordic Pure 20x25x5 Furnace Air Filters

  We had our furnace replaced last year and had a Lennox SLP98V 98% efficiency unit installed because it wasn't much more than the lower efficiency rated units. Wow, what a difference the furnace made in our monthly gas bills, they dropped by quite a bit which will more than make up the difference of saving money by getting a lower efficiency unit. Enough about our furnace, this review is about the Air Filter. I looked up the price on the Lennox X6675 replacement filters and they linger around $100 each which I thought was a bit much. A quick search on Amazon showed these Nordic Pure filters at less than a 1/4 of the cost vs. the Lennox and they had good reviews so I thought I'd give them a try. The first thing I noticed is that the original Lennox is a MERV 16 filter while these Nordic Pure filters are MERV 12. If you're not an HVAC guy, like me, then you would not have a clue what this meant, so a quick internet search showed me the difference between the different MERV ratings and this is what I found: "Filters with a merv rating of 9 to 12 are used in commercial and industrial applications and will stop particles in the 1 to 3 micron range. These filters are a great choice for home owners who want the best dust control possible. When using filters with Merv 9 ratings and above it is important to clean or replace them when recommended by the manufacturer because they will have a negative effect on air flow when they become dirty. This can lead to performance problems and decreased operating efficiency. The most efficient filters have merv ratings of 13 to 16 and will stop particles as small as .3 microns. These filters are used in hospitals and other super clean environments." Okay great, well my home is not a hospital nor a cleanroom environment so I think I'm going to be just fine with a MERV 12 filter :) The next thing I noticed is that not all 20x25x5 filters are the same size (surprise, surprise) and the ones I ordered from Amazon (which is the product I'm reviewing here) are a little bit bigger than the X6675 filter from Lennox. My front filter cover plate did not want to seat all the way until I kind of banged it in. So, if you have a Lennox furnace and you find these filters are a tad big, do a search on Amazon for X6675 and you'll find there is a Lennox version of this filter that is sized appropriately, or click the link here Nordic Pure 20x25x5L2M12-2 Lennox X6675 Replacement MERV 12 Pleated Furnace Air Filter, Box of 2. Yes, they are a little more expensive than these filters, but they will fit correctly, and remember, you're still saving almost $150 over buying two Lennox filters! As to how the filter performs, well I just bought them so I cannot say, but I fully expect them to perform as well as any other 20x25x5 filter. I give these filters 4 stars because they do what they are supposed to do and at a much cheaper price than the alternative "name brand" filters. Read more
