Most Frequently Asked Question:

1. i have used the filter for 6 months but doesn’t see like it is dirty, does that indicate it is not working well? thanks

I can tell you I bought these filters because my wife has allergies and we hoped that these filters would help keep junk out of the air and help her coughing.

And it has, for us anyway!

We have three returns int he house and have these filters in all three. We change them every 90 days and sometimes they do look dirty and other times they don’t; depends on how much your symtem runs.

2. do the number of pleats really matter?

The act of filtering air actually slows down the flow, so to help make up for the reduced airflow they add pleats which significantly increases the surface area of the filter, which increases the flow without reducing the filtration. Fewer pleats = less surface area = reduced air filtration per minute. More pleats = more surface area = increased air filtration per minute.

So yes, the number of pleats matters.

More pleats are *usually* a sign of a higher quality filter, but not always — you can put a lot of pleats into a crappy filter too, but most don’t.

3. What’s the model number

Our SKU for this product is: P80S.042025.MKT – The actual size of this filter is 19 1/2″ x 24 1/2″ x 3 3/4″, please ensure this is the size you need before you order. Customer Care Department at Air Filters Delivered – SAM

4. does anyone have a whistling sound coming from air duct ?

The fit is allowing a space for the forced air makes the sound. Play with the edge of the filter and you will locate and fix the gap.
What Real Customers Say About This Product?

The Last Mind Crusader says: “It is often a pain buying filters for the AC/furnace: more economical to buy a bunch, prices vary, ratings vary, brands vary . . . and you throw out the filter in a month or so! You just want it to work. I thought I would order some online through amazon and it worked out wonderfully. They were reasonably-priced and I got a higher R rating for the product than a lesser rating at a greater price. It arrived on time. No damage. And the filters work! This will be my source for future filters.

What Real Customers Say About This Product?

Amazon Customer says: “I immediately replaced my filter which I got from Home Depot which this. It’s slightly smaller than 20x25x1, but it shouldn’t be a problem for my AC return. I can only imagine this would save a lot of trouble for others buyers if it is printed clearly next to the size advertised on amazon. Although on the filter itself the actual size as well as the advertised are both printed. Overall I would say this seems like a great buy for the money. They come in 4.

5. Nordic Pure 16x24x1 MERV 12 Pleated AC Furnace Air Filters 6

Style:MERV 12 | Size:6 Pack Product Description Nordic Pure MERV 12 Pleated AC Furnace Air Filters provide exceptional filtration for both home and commercial environments. Each time air passes through a Nordic Pure pleated furnace air filter, lint, dust, pollen, bacteria, pet dander, dust mites, mold spores, smoke particles, virus carriers, allergens and other contaminants are removed. MERV 12 furnace filters are comparable to HVAC filters with the rating of MPR 1500-1900 or FPR 9.

While different companies use different scales to measure the air filter’s efficiency, Nordic Pure chose to follow the industry standard, MERV, as developed by ASHRAE (the American Society of Heating, Refrigeration and Air Conditioner Engineers). No matter the name of the rating, the efficiency of all air filters is rated according to the same criteria as set forth by ASHRAE. Nordic Pure furnace air conditioner filters are manufactured using a heavy duty, moisture resistant beverage board frame.

As with all Nordic Pure furnace air conditioner filters, the material is electrostatically charged to attract unwanted particles. The media used will not promote the growth of bacteria or mold on the air filter and is better at trapping airborne particles than fiberglass filters. Our attention to the smallest of details results in a healthier living space. For fresh, clean air in your home and office, it is important to regularly change your AC filter, especially during home improvements.

We recommend changing your HVAC furnace filter every 1-3 months, depending on your unique home or office environment. People with pets or those who suffer from allergies should change their A/C air filters more often. Replacing your air filter regularly not only improves indoor air quality, it helps your HVAC unit perform more efficiently. Important Note: Almost all air condition filters have a different Actual Size (the exact dimensions) than Nominal Size (the name) printed on the air conditioning filter.

It is best to measure the exact size of your A/C filter and compare it to our Actual Size to be sure your HVAC replacement filter fits! From the Manufacturer 16x24x1 MERV 12 Pleated Air Condition Furnace Filter Box of 6-Manufactured by Nordic Pure.

Nordic Pure 16x24x1 MERV 12 Pleated AC Furnace Air Filters 6 Pack

  • Nominal Size: 16 x 24 x 1, Actual Size: 15 1/2 x 23 1/2 x 3/4 (15.5 x 23.5 x 0.75)
  • Attracts indoor allergens, dust, pollen and other airborne contaminants.
  • Hypoallergenic and antimicrobial pleated electrostatic filter material
  • Nordic Pure recommends changing 1” air filters every 30-90 days
  • Made in the USA
Most Frequently Asked Question:

1. What is the actual measurement of the 16 X 24 size?

I ordered the 18x18x1. It’s actual dimensions are 17.75×17.75x.75. It fits my HVAC just fine.

2. What is actual size? A review says the filters are smaller than specified.

Actual size of the filter is 15 3/8 x 23 3/8 x 3/4″.

3. how much activated carbon is in the filters?

I’m not sure but we bought them because of fire in our area and from inside the house there is no hint of fire smell. They work great.

4. This fits loosely in my furnace. Wont the air just go around the edges and bypass the filter altogether

in my opinion no furnace air filters will fit perfectly. It fits loosely in mine also but the strong intake air pulls it tight. Nothing is 100%. This does a great job. You can also contact the manufacturer and pose that question to them.

Be aware that these filters are DESIGNED to be about 1/2″ underside for a reason! Note: I put this under 5 star and not 1 star so as to not downgrade a great filter.

If you own a house like ours then the cheapo builders take as many shortcuts as possible and just cut a hole in the HVAC duct work and shove a filter into the slot. A full sized filter will NOT fit. So you need to order filters made 1/2″ undersized since the metal ducts are measured on their outside while the filter needs to fit into their inside. Often this is called “American” sized filters.

If you have a quality home with a fully manufactured filter housing then you most likely need full size filters to fill the hole. Filters made oversea (IE – China) are measured the to the exact size as labeled and work just fine with a “REAL” filter housing. Run to the local home discount store and pick up brand XYZ and Bob’s your uncle. Normally this would be a good thing. With building standards in this country that allow 2″x4″ lumber to be 1-3/4″ x 3-3/4″. The so-called reason is wood is measured prior to the final shaping these days, but not in the past.

Building codes also don’t require a sealed filter housing, I guess, and so in the case of our very expensive tract house a huge hole was hogged out of the duct side for each of our two HVAC systems resulting in gobs of air is sucked into the hole bypassing the filter. The one in the attic sucks in cold air in winter, hot air in summer and dust, fiberglass particles and whatever else is found in the attic of a house. We need to purchase undersize filters, tape the filter into the openings and repeat as often as necessary. This is a case of nothing is standard unless you demand it yourself in writing when you contract HVAC installation or buy a house. Buy a tract shack from one of the big national home builders and get crap for filter housings and fall in love with N.P. filters. We love the “American” size (undersize) filter like Nordic Pure, else we need to spend time cutting down the discount H.D./L’s filters doing our own engineering project of the month..

Most Frequently Asked Question:

1. Do I just slip the box into the furnace? The replacement one, different brand, has caps on each end and folds like an accordian.

Yes, you just slip the whole thing in the furnace. Be mindful of the air flow direction so that the filter is placed going the correct direction.

2. How many runtime hours will this filter last?

I dont have an exact hours answer ro give you but here goes. I live in Florida and my ac runs pretty much 24/7 except when the weather gets cooler like this weekend. The filter in my house is usually good for 3 to 4 months. I have lung issues so I like to change it around 3. If you aren’t sure, buy one and watch the filter at about 2.5 months. You will start to see the color change as it holds allergens, etc.Hope this helps.

What Real Customers Say About This Product?

These ‘MADE IN THE USA’ 🇺🇸 filters are pricey, but, well worth the cost.
The dust in my home has decreased considerably.
This particular MERV level has drastically improved indoor air quality, however, it’s imperative that your particular HVAC system is capable of running a higher MERV rating.
Per Grainger, “When selecting the right filter for your application, higher is not always better. Using an air filter with a MERV rating higher than what your furnace or air conditioner manufacturer recommends can actually impair its performance.”
Lastly, Amazon uses the least expensive packaging when sending these filters, so they were damaged in transit. Frustrating to say the least.
However, these are the best filters I’ve used to date & I highly recommend them if you desire cleaner air with noticeably less dust, dust mites, pollen, and allergens.

Compare these filters with 3m filtrete brand filters with carbon saturated media, including odor reduction models.

AIRx ODOR 20x20x1 MERV 8 Carbon Pleated Air Filter – Made in the USA – Box of 6

  • Marv 8 carbon 20x20x1 furnace filter premium pleated filter
  • Traps foul household odors using carbon saturated filter media
  • Better airflow and efficiency, by using more pleats than most retail air filters
  • Made in U.S.A.
  • Compare to Filtrete odor reduction
Most Frequently Asked Question:

1. Has anyone tried this for a small spray booth to filter vocs? how well does it work?

havent tried it for that but MERV 5 is needed for filtration in spray booth, this exceeds that and carbon filters will reduce VOCs, may have to change filters frequently though as when the carbon becomes saturated will stop trapping fumes and they will blow right back in the air

2. How does this filter reduce odor?

Carbon fibers are embedded throughout entire filter. So the carbon acts to “catch” anybodors passing thru.

3. This is advertised as a 3 month filter. Is this information(3month) stamped anywhere on the filter?

Not that I can see. BUT, it’s a darn good filter. I change it out every 2 months. Cheaper than 3M Purple filters and just as good, as far as I can tell. I will continue to use and buy.

17. Nordic Pure 16x25x4 MERV 8 Pleated AC Furnace Air Filters 2

Size:2 Pack | Style:MERV 8 | Pattern Name:Air Filters Product Description Nordic Pure MERV 8 Pleated AC Furnace Air Filters provide exceptional filtration for both home and commercial environments. Each time air passes through a Nordic Pure pleated furnace air filter, lint, dust, pollen, bacteria, pet dander, dust mites, mold spores and other contaminants are removed. MERV 8 furnace filters are comparable to HVAC filters with the rating of MPR 800 or FPR 6.

While different companies use different scales to measure the air filter’s efficiency, Nordic Pure chose to follow the industry standard, MERV, as developed by ASHRAE (the American Society of Heating, Refrigeration and Air Conditioner Engineers). No matter the name of the rating, the efficiency of all air filters is rated according to the same criteria as set forth by ASHRAE. Nordic Pure furnace air conditioner filters are manufactured using a heavy duty, moisture resistant beverage board frame.

As with all Nordic Pure furnace air conditioner filters, the material is electrostatically charged to attract unwanted particles. The media used will not promote the growth of bacteria or mold on the air filter and is better at trapping airborne particles than fiberglass filters. Our attention to the smallest of details results in a healthier living space. For fresh, clean air in your home and office, it is important to regularly change your AC filter, especially during home improvements.

We recommend changing your HVAC furnace filter every 1-3 months, depending on your unique home or office environment. People with pets or those who suffer from allergies should change their A/C air filters more often. Replacing your air filter regularly not only improves indoor air quality, it helps your HVAC unit perform more efficiently. Important Note: Almost all air condition filters have a different Actual Size (the exact dimensions) than Nominal Size (the name) printed on the air conditioning filter.

It is best to measure the exact size of your A/C filter and compare it to our Actual Size to be sure your HVAC replacement filter fits! From the Manufacturer 16x25x4 MERV 8 Pleated Air Condition Furnace Filter Box of 2-Manufactured by Nordic Pure.

Nordic Pure 16x25x4 MERV 8 Pleated AC Furnace Air Filters 2 Pack

  • Actual Size: 15 1/2 x 24 1/2 x 3 5/8 (15. 5 x 24. 5 x 3. 63)
  • Attracts indoor allergens, dust, pollen and other airborne contaminants.
  • Hypoallergenic and pleated electrostatic filter material
  • Nordic Pure recommends changing 4″ air filters every 3-6 months
  • Proudly Made in the USA
Most Frequently Asked Question:

1. Received. concerned filters look generic. no label saying nordic pure. more concerning, nothing saying merv 12. would like reply from manufacturer

I suggest you go right to the questions for seller to receive this reply. Any I have always purchased as NORDIC Pure are clearly labeled as such. Be conscious of wording that says ” Works like Nordic Pure” for less etc. Fine print can trip you up, but Amazon does not stand for that. Make sure you get what you pay for Nordic Pure is Nordic Pure not an imitation filter even made to the same specs.

2. I bought this to replace a honeywell filter. it does not fit snug. should i use it or no? i don’t want to damage my system.

Unfortunately, Amazon doesn’t give the full details from Nordic Pure, the manufacturer, which tells you this is not a replacement for Honeywell or Filtrete 16x25x4 and you need to order the 16x25x5 for these replacements.On our website we say:
* If you are using a Filtrete filter Click Here to order our 16x25x5 Honeywell/Lennox Replacement air filters.
* Measure your current air filter and compare with the Actual Size of this item to make sure you order the correct filter.
IMPORTANT Note: Air filters have an actual size that is a fraction of an inch smaller than the standard size (also known as “nominal size”). The size printed on your air filter may NOT be the Actual Size. With the 4″ and 5″ air filters there is a wider variance between the nominal size and actual size for the different manufacturers. Because of this, the air filter you are replacing could be called a 16x25x4 but really be the same as our 16x25x5. If you are currently using a 16x25x4 Filtrete filter in your Honeywell unit you should order our16x25x5 Honeywell Replacement that measures 15 3/4 x 24 3/4 x 4 3/8 (15.75×24.75×4.38). This is why we ask you to measure your air filter so you aren’t surprised if the air filter doesn’t fit!

3. What’s the difference between Merv 8 and Merv 12? Which one is better and why?

Good morning.A MERV 12 picks up more particulate than a MERV 8 but can also place more restriction on your system.A MERV 8 is a commonly used household MERV and gets most household particulate.The 12 will collect a finer particulate as well as pet dander, tobacco smoke, auto emissions, firewood smoke, and fine dust.It just depends on your particular needs.However, if your system is older a 12 may place too much air restriction.

4. How long is this supposed to last before replacement?

Twice per year or every 6 months.We were told to replace filters with our Autumn and Spring system checks.That’s not to say we haven’t used them just fine for an entire year if you don’t have pets or a lot of construction in the area or dust they’ll probably do okay do for a year.I prefer to change them at 6 months, my husband prefers annually.

What Real Customers Say About This Product?

J. Dahl says: “A good quality filter for a good price that fits my industry-standard 16x25x4 filter housing perfectly. It appears that a lot of reviewers are disappointed that these are slightly smaller than the stated size, which it would have to be to fit into a housing that is 16x25x4. Where the negative reviews come from is people who bought proprietary (non-standard) Honeywell filter housings, which are intentionally a bit oversized to keep you from buying filters like these made by other manufacturers. In short, blame Honeywell, or blame yourself, but don’t blame these filters for not fitting your proprietary housing.
