14 best filters now furnace air filters

Furnace air filters are crucial components of heating, ventilation, and air conditioning (HVAC) systems, contributing to indoor air quality and the efficient operation of the system. Here are key points related to furnace air filters:

  1. Functionality:

    • Furnace air filters are designed to capture dust, dirt, pollen, pet dander, and other particles from the air as it circulates through the HVAC system. This helps improve indoor air quality by preventing these particles from being recirculated into the living spaces.
  2. Types of Filters:

    • There are different types of furnace air filters available on the market. Common types include fiberglass, pleated, electrostatic, and HEPA (High-Efficiency Particulate Air) filters. Each type has its own efficiency level and is suitable for specific needs.
  3. MERV Rating:

    • Filters are assigned a Minimum Efficiency Reporting Value (MERV) rating, ranging from 1 to 16. The MERV rating indicates the filter's ability to capture particles of different sizes. Higher MERV ratings correspond to higher filtration efficiency.
  4. Replacement Schedule:

    • Furnace filters need to be replaced regularly to maintain optimal performance. The replacement frequency depends on factors such as the type of filter, the MERV rating, and the level of airborne contaminants.Neglecting to replace filters can lead to decreased system efficiency and air quality issues.
  5. Choosing the Right Filter:

    • It's important to choose a filter that is compatible with your HVAC system. Refer to the system's manual or consult with a professional to determine the appropriate filter size and type.
  6. Installation:

    • Installing a furnace air filter is typically a straightforward process. However, it's crucial to follow the manufacturer's instructions and ensure that the filter is inserted correctly, with the airflow direction indicated on the filter.
  7. Benefits:

    • Regularly replacing and using high-quality furnace air filters can lead to several benefits, including improved indoor air quality, reduced energy consumption, and increased longevity of the HVAC system by preventing the accumulation of debris on internal components.
  8. Health Considerations:

    • For individuals with respiratory conditions or allergies, choosing a filter with a higher MERV rating can be beneficial in trapping smaller particles that may exacerbate symptoms.

In summary, furnace air filters play a vital role in maintaining a healthy indoor environment and ensuring the efficient operation of HVAC systems. Regular maintenance, including timely filter replacement, is essential for optimal performance.

User questions & answers

Question: i recently got these mpr1000 filters now i hear near the air vents like im guessing dust move around not sure if its normal
Answer: Due to the design of it, the lock bar most likely won't snap in place if anything is placed between the filter and the case. Some saw dust is normal. It's a design flaw unfortunately. Honestly haven't had any running issues from the way it is set up.
Question: Does this filter contain fiber glass
Answer: Cold tap water. Don't use hot water in your humidifier. Some people use distilled water, but that's an expensive proposition if you're running the humidifier all day or all night long.
Question: are these filters a true 16x20? I have run across some that are fifteen and three quartes by 19 and three quarters and they will not stay seated an

Nordic Pure 16x25x4 MERV 12 Pleated AC Furnace Air Filters 2 Pack

Nordic Pure

Based on 3 reviews Check latest price

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

Nordic Pure 16x25x4 MERV 12 Pleated AC Furnace Air Filters. Actual Size: 15-1/2-Inch by 24-1/2-Inch by 3-3/4-Inch. Changing your air filter is the first step in insuring your HVAC system runs at its optimal level this season. Generally, you should change your 4-Inch air filters every 3 to 6 months. Particles in indoor air are measured in microns, which are 1/1000 of a millimeter. A human hair is about 100 microns wide. A Nordic Pure air filter captures airborne particles as small as 0.3 microns! Nordic Pure air filters do not kill germs, however, the filter media does not permit the growth of bacteria or mold. As a result, it is not necessary to add any potentially irritating chemicals to the air filter to kill germs. Nordic Pure air filters are made out of an electro statically-charged synthetic material that draws airborne particulates to it like a magnet. Electrostatic filters help trap airborne particles to protect your family from allergy causing pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses.

  • 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. Antimicrobial
  • Nordic Pure recommends changing 4" air filters every 3-6 months

User questions & answers

Question: How long is this supposed to last before replacement
Answer: 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.
Question: What's the difference between Merv 8 and Merv 12? Which one is better and why
Answer: 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.
Question: 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
Answer: 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 our 16x25x5 Honeywell Replacement that measures 15 3/4 x 24 3/4 x 4 3/8 (15.75x24.75x4.38). This is why we ask you to measure your air filter so you aren't surprised if the air filter doesn't fit!
Question: Received. concerned filters look generic. no label saying nordic pure. more concerning, nothing saying merv 12. would like reply from manufacturer
Answer: 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.

User questions & answers

Question: Does this filter have foam rubber strips down two of the sides like other filters, to make a precision seal to the Hvac system
Answer: NO !! It is a full 20" X 20" X5" - if you want foam rubber you will get a smaller filter. Mine fits tightly and I'm not worried about needing the foam rubber strips glued to the sides. CEA
Question: how long does it last
Answer: The experts recommend changing your filters every 3 to 6 months. If you have high dust levels or animals in the house you may need to do it more often. We change ours out every 8 to nine months and they always seen to have very little built-up on them. These filters did the job.

With the 4-Inch and 5-Inch filters there are many different exact sizes for the different HVAC manufacturers. Because of this, your filter may say 16x25x4 on it but really be the same as our 16x25x5. This is why we ask you to measure your filter so you aren't surprised if the filter doesn't fit! You may also want to look at our Honeywell replacement 16x25x5 filter. Just check the "Actual Size" before ordering. Nordic Pure air filters are made out of an electro statically-charged synthetic material that draws airborne particulates to it like a magnet. Electrostatic filters help trap airborne particles to protect your family from allergy causing pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses. A MERV 121 Nordic Pure air filter captures airborne particles as small as 0.3 microns! Our air filters do not kill germs, however, the filter media does not permit the growth of bacteria or mold. As a result, it is not necessary to add any potentially irritating chemicals to the air filter to kill germs.

  • Nominal Size: 16-Inch by 25-Inch by 5-Inch
  • Actual Size: 15-3/4-Inch by 24-3/4-Inch by 4-3/8-Inch
  • Nordic Pure brand replacements for Honeywell units
  • Replacements for Honeywell F100F1012, FC100A1026, FC100A1029, FC100C1009 and FC200E1029
  • MERV 12 filter media to help reduce pollen, pet dander, dust, mold and more

User questions & answers

Question: What does the merv designation mean and is merv 12 better than merv
Answer: http://lmgtfy.com/?q=MERV+rating Minimum Efficiency Reporting Value (MERV) is a standard that rates the overall effectiveness of air filters. Higher value MERV rating equates to finer filtration, meaning fewer dust particles and other airborne contaminants can pass through the filter.
Question: Do these really last 3 months? i currently replace the 16x25x1” merv 14 monthly
Answer: This product is a 4-5-inch filter (in your question you listed a 1-inch filter. Those typically need to be changed every 1-2 months.) The effective life of your AC air filter depends on both the inside and outside conditions in which you live. It is important to regularly change your furnace air conditioner filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your 4- and 5-inch air filter every 3-6 months to maintain maximum efficiency and economy.
Question: Is this actually a two filter package for the stated price
Answer: No, this is actually the cost per filter but they do last 4 x 6 months and I have three little dogs running around the house
Question: what is the recommended change period on these fileters
Answer: Generally, you should change your 1/2", 1" and 2" air filters every 30, 60, or 90 days; the 4", 5" and 6" air filters should be changed every 3 to 6 months, depending on your environment. Thanks, Jessica

User questions & answers

Question: Why is there not an option for the size 14x30x
Answer: Take a look at filterbuy and see if you can find that size.
Question: My hvac system is 30 years old. I have an old magic chef one just wondering if this will be ok to use for it, we have a very musty smell in the house
Answer: A: If you haven't upgraded you system I would recommend starting at MERV 8 then going up or down depending on how your system responds. Unfortunately the manuals for the Magic Chef units are extinct. They've been purchased and merged into a handful of companies since the 80's. This link will provide a great resource about MERV ratings and what their best use is. I have horrible allergies so I use MERV 14 in one HVAC system. It's hospital quality. In our other house we use MERV 8 and it does well in our 10 year old unit. It catches a lot of dust and pet hair. It's a great middle ground. The higher the MERV rating the higher the cost, so experiment and see what works. United Filter : https://unitedfilter.com/merv-ratings
Question: We have a problem with not enough air conditioning flow in the upper level of the house. Would this filter make that worse
Answer: Two things can equalize upstairs and downstairs cooling. #1 If you don's have one, have a thermostatically controlled exhaust roof fan installed. They are the metal mushroom shaped things on roofs with fans inside, they exhaust the super-heated air out of the attic and make a huge difference in upstairs comfort b/c that blanket of 110 degree or more air is now at least closer to the actual outside temp. #2 Set your circulation fan to run all the time vs. turning off after every cooling cycle. Set "FAN" switch to ON vs. AUTO. If your source and return registers are working good then now the temperature of the house won't tend to "stratify" or get layered when the downstairs thermostat is happy but the truth is there's a large temp diff between floors b/c heat rises. Running the fan will help to keep cycling the whole house air and keep it mixed. Plus it gives the thermostat better knowledge of what's really going on. But, I can't stress enough on the roof fan.
Question: Im wondering how much flow this filter cuts back, i currently use the 2200 filters with no problem anyone had any experience yet
Answer: from what I have read the pressure drop of the 3M 2800 (merv 14, 97%) is .24 psi. the 2200 is I think .20 to .22 psi for the 3M filters.

Meet or Exceed Industry Standard for Efficiency and Performance

All of our AIRX FILTERS WICKED CLEAN AIR. filters meet or exceed the industry standard for filter efficiency by particle size and performance.

National Air Filtration Association

As a member of the National Air Filtration Association (NAFA) we are committed in manufacturing air filter products to maintain a clean and healthy indoor environment through effective air filtration.

Made in the USA

AIRX FILTERS WICKED CLEAN AIR. air filters are made in Greenwood, Indiana with great attention to quality.

Why MERV rating and filter thickness is important?

MERV stands for Minimum Efficiency Reporting Value and is an industry standard to rate a filters efficacy. We recognize this is not very easy to understand for consumers, so we developed our simple to use application naming system. Simply pick the filter that suits your needs.

Allergies, pets, odors and smoking all can greatly affect the quality of your indoor air. Discount Filters offers many different types of air filters to help you breathe easier and choose the correct filter based on your specific needs.

Ensuring that your filter fits properly in your HVAC system means making sure that you have not only the right length and width, but also the thickness of your filter.

Most standard air filters are 1 - 2 inches in thickness. Whereas media filters are typically 3 to 5 inches in thickness. The best way to measure your air filter size is to get out the measuring tape and measure it directly. Also your current filter probably has the dimensions printed on the frame.

User questions & answers

Question: Why does the qr code on the actual filter pull up a merv 8 rating vs the stated merv
Answer: Yes, that was my concern also. It appears that the product is not what it is advertised to be. I did not find Merv 13 marking on the filter. It was only marked on the package. In stead of using it, I purchased a Honeywell filter.
Question: What are actual deminsions of 20x20 filters
Answer: The filter actually states 20x20x2, our furnace requires those dimensions so I assumed that was the actual size. I’ve never measured them.

User questions & answers

Question: Where are they made
Answer: When I had one of these I had to wash it with 409 and let it sit for about five minutes and then hit it with a shower head for pressure and it always came out beautifully
Question: These came in an amazon box with no wrapping of any kind. Wouldn’t it be bad for a filter to not be protected from particles
Answer: I have 2 5T units in house that uses this filter and after changing many various Mfr filters which all seemed to work comparably well and about the same in last 21+ years, never once did I ever think about counting pleats. All I ever counted was the price! Did I miss something?? Bill
Question: Do these merv 11 filters have enough air flow for any furnace
Answer: Yep
Question: Does it a Space Guard
Answer: The N95 masks are the equivalent to a MERV 16. Our MERV 13 filters are made with a 100% synthetic filter media with a wire backing glued in a cardboard frame. There are no harmful materials in the MERV 13 media itself. If you use the media it will not filter as small of a partical as the N95 but it help filter out 1.0–0.3 μm particle size. These filters can filter bacteria, droplet nuclei (sneeze), cooking oil, most smoke and insecticide dust, most face powder, and most paint pigments.

Nordic Pure 20x20x4 MERV 12 Pleated AC Furnace Air Filters 2 Pack

Nordic Pure

Based on 1 reviews Check latest price

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

Nordic Pure 20x25x4 MERV 12 Pleated AC Furnace Air Filters: Actual Size: 19-1/2-Inch by 24-1/2 -Inch 3-3/4-Inch. IMPORTANT NOTE: Almost ALL filters are a fraction of an inch smaller than the nominal size printed on the filter. It is best if you measure your filter for the EXACT size and compare it to our "Actual Size" listed above. With the 4-Inch and 5-Inch filters there are many different exact sizes for the different HVAC manufacturers. Because of this, your filter may say 20x25x4 on it but really be the same as our 20x25x5. This is why we ask you to measure your filter so you aren't surprised if the filter doesn't fit! You may also want to look at our Honeywell replacement 20x25x5 filter. Just check the "Actual Size" before ordering. Changing your air filter is the first step in insuring your HVAC system runs at its optimal level this season. Generally, you should change your 4-Inch air filters every 3 to 6 months. Particles in indoor air are measured in microns, which are 1/1000 of a millimeter. A human hair is about 100 microns wide. A MERV 12 Nordic Pure air filter captures airborne particles as small as 0.3 microns! Nordic Pure air filters do not kill germs, however, the filter media does not permit the growth of bacteria or mold. As a result, it is not necessary to add any potentially irritating chemicals to the air filter to kill germs. Nordic Pure air filters are made out of an electro statically-charged synthetic material that draws airborne particulates to it like a magnet. Electrostatic filters help trap airborne particles to protect your family from allergy causing pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses.

User questions & answers

Question: Will this work to filter the smoke from forest fires across the state
Answer: Per ASHRAE, yes, a MERV 15 air filter will filter out smoke and ash. Keep in mind, however, there is nothing short of a clean room to remove the odor completely. Thank you for your inquiry. We appreciate your business!
Question: does this filter fit a "lennox" furnace
Answer: Most Lennox units take a 4 3/8 depth filter. That would be the Nordic Pure 20x20x5. AC Furnace filters have both a nominal size and an actual size. It is best to either measure the cavity where the filter goes or use the measurements of your existing filter.
Question: Are the filters delivered in a sealed plastic or just lose in a box and are there any assurances that we will not receive a returned filter
