    Customer Reviews

    The HVAC company said 4" filters have more surface area and therefore last longer and do a better job of filtering than the 1" o Got a new HVAC system installed about two years ago. The HVAC company said 4" filters have more surface area and therefore last longer and do a better job of filtering than the 1" ones. There's more surface area, so that makes sense. Unfortunately, they made the opening so it would only fit a Top Tech brand which are pricey. I tried other brands from Home Depot, Lowes, etc., but they were all a little too big in one or two dimensions. Finally came across Nordic Pure and it fits perfectly. Whatever you buy, carefully measure the dimensions of the opening and the existing filter then check the ACTUAL dimensions of the filter you're planning to purchase if you want to try a different brand.The air filter opening is simply sheet metal, so if you have a 1" filter and want to switch to a 4", I don't imagine it would cost terribly much to pay an HVAC or sheet metal company to redo the filter opening. Just a random thought. 5Why is 20x25x4 not actually 20x25x4? As others are noting, the actual dimensions are quite smaller than expected. It doesn't fit snug in the furnace, so I get a bit of a rattle. To be fair, the 3M filter I replaced with this was actually 4 and 5/16 wide. This made the overall difference 11/16, which doesn't look like a lot, but in the furnace the difference was being held securely or rattling around. Plus, the 3M filter had much more surface area, so I'll be spending the extra and going back to 3M filters. 2FALSE ADVERTISING In the fine print "Actual Size of Filter: 19-1/2 x 24-1/2 x 3-5/8". Why does it read 20x25x4? It should not have that as it's advertised size. I've been buying filters for this furnace for years. It does not fit. It should be the 20x25x4 that it says not a different dimension in the fine print. 1Works Great! Just Measure First!! Fits and works well; much better than the OE one that came with the system. Don't believe all the bad reviews (Filters in general get a lot of bad reviews due to people ordering based on the Nominal Size.... a 2x4 isn't really 2"x 4" people ;-) ...). BEFORE YOU ORDER; take a few minutes and make note of the Actual Size of your old filter (should be printed on the side and they ALL vary depending on manufacturer) then measure the filter opening of your system (For example; my system could take a slightly larger filter than what it came with). LAST: Read the description on Amazon for the actual size, double check, order then enjoy your clean air! 5The best filter, hands down! I bought these for an air purifier I am going to make for my townhouse. I have made a few different designs over the last few years, and have done experiments to see what design works the best. My design uses two HVAC filters. I have tried many different filters, and while they worked OK, I never found a filter that worked as I thought they should. I did find some online that claimed they were Merv 13, but they were more like Merv 8 and we're very poor quality.However, i finally found these Nordic Pure Merv 15 filters, and they are awesome! I am so pleased to finally find a filter that performs to fit my needs. I have tested these filters and can tell you that they are Merv 15, and the best HVAC filter you will find for the price; trust me, I've looked. Not only do they filter better than any filter I've tried, they are also the same price as any store bought Merv 12 filter!The filter is not a true 20x25. This is normal for aftermarket filters. It's smaller to filt different HVAC units. OE filters are usually an exact 20x25. The build quality of the filter is better than other aftermarket filters I've tried. You should note that this is not the same build type as some highend merv 15-16 filters. High-end Merv 15-16 filters are much higher quality to meet hospital regulations and requirements, and are much more expensive.Nordic Pure is an American company, and their filters are made in the USA. If you are looking for a quality aftermarket HVAC filter, I highly recommend Nordic Pure 5Beware if you use these with an electronic ionization air purifier I have a complete Bryant Evolution Heating and Cooling system, including a GAPAA2025 Perfect Air Purifier. This is an electrostatic ionization unit that requires non metallic air filter cartridges. I temporarily used the Nordic Air 20x25 filters while doing remodeling since they are far less expensive that the Bryant filters. I could hear a very rapid clicking noise coming from the filter area. My HVAC Tech showed me where the small wires on the back side of the Nordic filters were ground sparking to the frame of the Bryant equipment. He theorized that the small charge passed on from the ionization part of the Bryant equipment was being grounded by the small wires on the back of the Nordic filter. We took the Nordic filter out of the system and the clicking sound went away. When we dimmed the lights and we could actually see the ground sparking off the Nordic wire on the reverse side of the filter. These are great fitters if you don't use them with the Bryant Perfect Air Purifier. Far less expensive than the Bryant version. 1The sizing is NOT correct Ignore the 20x25x4 - it's just a dumb name that means NOTHINGThe filter is WAY smaller than that - I had to tape sheetrock to it to get it to fit and even still - it's only 3" thick (not 4") 1Good product, good value, I'll buy more in the future This is the second time i've ordered the Nordic Pure filters. They work well, helping to clean the air and are reasonably efficient for their HEPA 18 rating (Higher HEPA rating means more resistance to the air flowing through it, so you need a a balance).The price is good and in lesser parts of the house where we don't run the HVAC as often, they last much longer. Further, in an instance where one wasn't replaced (accidently) for 6 months, it still passed air and worked well with a coating of dust on the cleaner material. Yea, I'll order these again.This is a real review, generated by a human, that actually bought these from Amazon twice now. 4A MERV rating of 9 to 12 will stop particles in the 1 - 3 micron range. A great choice for homeowners for best dust control. Great product. We have been using this brand of filters in our furnace for 4 years, we change them out every 6 months.MERV, or Minimum Efficiency Reporting Value, is a numerical value given to filters in order to identify its filtering abilities.This is now an international industry standard. This standard is used for determining the filters ability to capture and hold dirt and dust in specific size ranges.A MERV rating of 12 means that Average Particle Size Efficiency in Microns is 1.0-3.0 80%-89.9%, 3.0-10.0 90% or greater. 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 homeowners who want the best dust control possible.I seldom have to dust. I think that this is a very good MERV rating for most households and getting a filter with a higher rating would be as waste of money as our filters rarely look used when we change them out.I 5Don't buy this! There was only one filter delivered in the box. Over $90 for one filter???? False advertising! It was advertised as a 6 pack. 1
