8 best filters now air filter 20x25x4s

A 20x25x4 air filter, often referred to as a furnace filter, is a specific size of filter commonly used in HVAC (Heating, Ventilation, and Air Conditioning) systems to improve indoor air quality by capturing dust, allergens, and other airborne particles. Here's what you need to know about these filters:

  1. Size: The designation "20x25x4" refers to the dimensions of the filter. It is 20 inches in width, 25 inches in height, and 4 inches in thickness. These filters are designed to fit specific filter slots in HVAC systems.

  2. Filtration Efficiency: The "4" in the filter size denotes its thickness, which allows for a larger surface area and higher filtration efficiency. Filters of this size are often capable of trapping smaller particles, including dust, pollen, pet dander, and some airborne contaminants.

  3. Furnace Filters: 20x25x4 air filters are commonly used in residential and commercial HVAC systems, especially in forced-air heating and cooling systems. They help keep the HVAC system's components clean and prevent the distribution of dust and allergens throughout the building.

  4. MERV Rating: Air filters are rated based on their Minimum Efficiency Reporting Value (MERV), which indicates their filtration efficiency. Filters with higher MERV ratings can capture smaller particles but may require more frequent replacement or maintenance. A MERV rating between 8 and 11 is typical for 20x25x4 filters, suitable for most residential applications.

  5. Filter Material: These filters are typically made of pleated filter media, which provides a larger surface area for particle capture. The filter material can vary, with some filters incorporating synthetic fibers, fiberglass, or other materials designed for efficient filtration.

  6. Filter Replacement: Regular replacement of air filters is essential to maintain proper airflow and filtration efficiency in your HVAC system. The recommended replacement frequency depends on factors like filter type, usage, and indoor air quality. Typically, 20x25x4 filters should be replaced every 3 to 6 months, but it's essential to follow the manufacturer's guidelines.

  7. Improved Indoor Air Quality: Using a 20x25x4 air filter can help improve indoor air quality by reducing the presence of airborne particles that can contribute to allergies and respiratory issues.

  8. Compatibility: When purchasing replacement filters, ensure they match the size (20x25x4) and the filter slot dimensions in your HVAC system. Different systems may require different filter sizes.

  9. Maintenance: In addition to filter replacement, regular HVAC system maintenance is crucial to ensure efficient operation. This includes cleaning and inspecting the system's components, such as coils and ductwork.

  10. Cost: The cost of 20x25x4 air filters can vary depending on the brand, MERV rating, and quantity purchased. Consider the trade-off between filtration efficiency and filter lifespan when selecting a filter that meets your needs and budget.

Using a 20x25x4 air filter in your HVAC system can help maintain a clean and healthy indoor environment by reducing the presence of airborne particles and allergens. Regular maintenance, including filter replacement, is essential to ensure your HVAC system operates efficiently and effectively.

User questions & answers

Question: Do these have a Merv rating
Answer: Test Data PEAK ARRESTANCE: 94.7 ASHRAE 52.1 Protocol INITIAL RESISTANCE 0.12" W.G. ASHRAE 52.1 ProtocolDUST HOLDING 165 grams ASHRAE 52.1 Protocol AIRFLOW RATE 300 FPM ASHRAE 52.1 Protocol END POINT OF TEST 0.50" W.G. ASHRAE 52.1 Protocol Typical MERV Rating 8 ASHRAE 52.2 Protocol
Question: How often do these filters need to be cleaned? And what is the accepted method for cleaning them
Answer: Cleaning depends on your environment. I clean mine roughly every 6 weeks or so, because in the Summer we have dust blown around our house. In the Winter I will clean it about every 2 months.Cleaning is easy and straightforward. You just remove the filter and spray it with water (opposite the direction of air flow). Once you've run water over it, simply let the water drain out, pat it down to get residual water off of it and re-install.
Question: Is it 4 inches thick, both frame and filter material
Answer: This filter consists of 2 inches of filter media in a 3-5/8 inch frame. Why not have 3-5/8 inches of filter media? One might think that the thicker the media, the better the filter. However, this filter uses electrostatic media to trap particles. The media must be compacted to a specific density for the electrostatic fibers to build static electricity and attract dust. They are not like regular paper media filters. If the media was any thicker...it would create too much air resistance.
Question: My AC filter slot is exactly 20x25x4 while this filter size is 19-1/2 x 24-1/2 x-3 5/8. Wont it be kind of loose and not fit properly
Answer: Thank you for your question. Our filters are undercut to allow for easy installation and removal. These filters are very rigid so slightly too small is better than slightly too big. There is a metal flange around the filter housing that allows for an undercut filter while still providing a good seal. That said..you are in the best position to measure and choose what size we make your filter. We can make any custom size in 1/8th increments for no additional cost.

Nordic Pure

Based on 39 reviews Check latest price

Product description

Nordic Pure MERV 13 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, coughs and sneezes, smog, allergens and other contaminants are removed. MERV 13 furnace filters are comparable to HVAC filters with the rating of MPR 2200-2400 or FPR 10. 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's air filters are pleated and electrostatic ally charged and have a high efficiency rating. The electrostatic charge of the air filters works as a magnet and draw airborne particles to them. This helps protect your family from pollen, fine dust, tobacco and cooking smoke, airborne plant spores, bacteria and some viruses. Our non-woven synthetic filter media will not support the growth of mold or bacteria, keeping your home healthier. Air filters are ranked in a minimum efficiency rating value (MERV) system. The higher the MERV rating, the better the air filter can filter out all airborne particulates. Remember not all HVAC systems can handle the higher MERV ratings. Filters that have received a rating of MERV 7-12 are great for all HVAC systems. However, MERV ratings of 13-16 are able to remove and capture smaller particle sizes even before the air filter starts to become dirty and are recommended for newer units. We manufacture most any size disposable home air filter in 1/2-Inch 1-Inch, 2-Inch, 4-Inch, 5-Inch and 6-Inch thickness. The printed size on the side of your air filters may be the nominal size so it is best to physically measure your filters with a ruler or tape to get the EXACT measurements of your home air filters within 1/8 of an inch on the length and width. Consult your HVAC system's operating manual for information. Nordic Pure recommends that you replace your filters every 1 to 6 months. That way, our filters will help your HVAC system to continue running to its best capacity. Nordic Pure has been manufacturing air filters since 1960 at our plant in Oklahoma. We are proud to be offering a MADE IN THE USA product. For Customer Service call 800-590-0339 or visit www.nordicpure.com.

User questions & answers

Question: I recieved the filter, but filter itself seems doesn't have any mark what merv is it. how do i check if i recieved correct merv13 filter
Answer: Please check the large label on the outside of your box. At Nordic Pure, the same filter frame is used for all filters that we manufacture. Our clean, white templates, or outer cardboard frames, are kept non-specific to save on manufacturing costs. By not printing a different frame for each of the many options that we offer, we keep our costs down and we pass those savings along to our customers. Rest assured that we manufacture only one filter option type at a time and therefore know exactly what MERV is being boxed as it exits the production line. The label on the outside of the Nordic Pure box guarantees that the filters inside are exactly what you ordered. Thank you for your business!

Answer: No. Just a regular furnace filter.
Question: Is this AFB Gold MERV 11 20x25x4 filter comparable and replacement for Honeywell FC100A1037? Too small
Answer: The exact size of this filter is 19.5 x 24.5 x 3.75. If you have an old Honeywell filter you could measure it so see how the size compares. (I bought this to replace a Filtrete filter, and was not impressed. It is slightly smaller than its given dimensions, and therefore loose in the slot. Also, there are much fewer pleats than any other filter I have bought, so it and can't hold as much dust.)

Question: What is the difference between 20x25x5hm15-2 and 20x25x5l1m15-2 (both nordic pure 15 merv 20x25x
Answer: The 20x25x5hm15-2 is the Honeywell replacement filters we offer. And the 20x25x5l1m15-2 will be the Lennox replacement filters we offer. These two models are the exact same filter size and material. We just have it listed differently to help customers find there size.
Question: If I order these filters will they say “merv 15” on the actual filters
Answer: My Nordic Pro filter did not say Merv15 on the filter. Next order was Lennox X6675 Merv 16. Merv 16 is printed on the filter. Side by side I think the Lennox is a better quality overall.
Question: Are these filters uv resistant? the filter will be in a plenum with a uv light
Answer: Yes, these air filters can be put in with a uv light. Thank you for your inquiry. We appreciate your business!
Question: How long do these filter last for
Answer: 5-6 months
Question: do 20 x 25 x4 and 20 x 25 x5 filters fit the same furnaces
Answer: No, the 20x25x5 is an inch wider than the other one and would not fit in the slot made for the 20x25x4. The reverse may work, but would likely allow too much air leakage around the filter.
Question: what is the difference between a merv 9 and merv 13 filter
Answer: Hello! The higher the MERV rating, the smaller the particle you will be able to capture. A MERV 9 will be about 40% efficient at capturing 1 micron particles, whereas a MERV 13 will be 80% efficient at the 1 micron level.

Product description

Nordic Pure MERV 13 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, coughs and sneezes, smog, allergens and other contaminants are removed. MERV 13 furnace filters are comparable to HVAC filters with the rating of MPR 2200-2400 or FPR 10. 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's air filters are pleated and electrostatic ally charged and have a high efficiency rating. The electrostatic charge of the air filters works as a magnet and draw airborne particles to them. This helps protect your family from pollen, fine dust, tobacco and cooking smoke, airborne plant spores, bacteria and some viruses. Our non-woven synthetic filter media will not support the growth of mold or bacteria, keeping your home healthier. Air filters are ranked in a minimum efficiency rating value (MERV) system. The higher the MERV rating, the better the air filter can filter out all airborne particulates. Remember not all HVAC systems can handle the higher MERV ratings. Filters that have received a rating of MERV 7-12 are great for all HVAC systems. However, MERV ratings of 13-16 are able to remove and capture smaller particle sizes even before the air filter starts to become dirty and are recommended for newer units. We manufacture most any size disposable home air filter in 1/2-Inch 1-Inch, 2-Inch, 4-Inch, 5-Inch and 6-Inch thickness. The printed size on the side of your air filters may be the nominal size so it is best to physically measure your filters with a ruler or tape to get the EXACT measurements of your home air filters within 1/8 of an inch on the length and width. Consult your HVAC system's operating manual for information. Nordic Pure recommends that you replace your filters every 1 to 6 months. That way, our filters will help your HVAC system to continue running to its best capacity. Nordic Pure has been manufacturing air filters since 1960 at our plant in Oklahoma. We are proud to be offering a MADE IN THE USA product. For Customer Service call 800-590-0339 or visit www.nordicpure.com.

User questions & answers

Question: I see a couple reviewers mention that there aren't any arrows on the filters showing the direction of air flow. Does it matter with these filters
Answer: It does matter which way the filter is installed. All of our filters have arrows indicating the direction of air flow. The wire mesh side is the side that the air flows and exits from to help support the media.
Question: How many filters does this come with for
Answer: This is a box of 3 filters. Thank you for your inquiry!
Question: Why are filters with carbon cheaper than without
Answer: Not sure where you found activated carbon filters in residential sizes that were 'cheaper'?? I use the MERV13 (without carbon) and can get 4 - 20x25x2 for $56. With carbon is higher. In any case, carbon filters will have the very same pleated surfaces, and will trap just as much dust and hair as non-carbon, and BOTH types will typically last 60-90 days. The 'activated carbon' ones are better at odor trapping, but even that doesn't last till the end of the filter (Carbon is porous and fills up rapidly as stuff flows over it)
Question: What's the difference between Merv
Answer: Merv 7 filters 50-69% and Merv 8 filters 70-85% of 3.0-10.0 Microns.
