Air filters come in a variety of sizes and types. The primary distinction between one filter and another is the size of the filter (length, width and thickness) and the filter material or “media” that is used in the manufacture of the filter. Nordic Pure features all of the popular sizes of air filters. Nordic Pure can also make a filter for your system if we do not stock your size. All custom filters can be ready to ship to you within 2 to 7 business days and usually costs about the same as many of our competitor’s ready-made filters.
Understanding how your air conditioning system works will help you understand how important quality air filters are to the overall health of your system and the air in your home. Air in a furnace or air conditioning system first enters the home through the air return where it passes through the air filter(s) and into the air handler, over the cooling coils or heat exchanger part of the HVAC system (where the air is either cooled or heated) and out through the ductwork into the home. The circulation throughout the HVAC system is accomplished through a powerful blower system. Because the air filter is the only device in the entire HVAC system capable of removing airborne impurities, it makes sense that frequent replacement of the air filter, as well as careful consideration as to the type of air filter you use, will directly impact the quality of your indoor air. Conversely, ignoring the HVAC systems air filter means you are allowing the entry of polluted air into the entire system, driving down operating efficiency, filling up ductwork with all dust, pollen, dust mites, etc. and other airborne pollutants while exposing the building’s inhabitants to polluted air. Though there are a wide variety of Air filters, they are generally termed as disposable air filters or reusable air filters.
Reusable Air Filters sound good, in concept. After all, replacement costs can add up over time. The problem is that reusable air filters do not do as efficient a job as desired. First, reusable air filters are messy when removed from the HVAC system. Then, there is the problem of finding a suitable area to clean the filters. Very often, highly toxic cleaners are required for adequate cleaning of reusable air filters. Once the chemical is used on the filter, it is absorbed into the filter and therefore a certain amount of the cleaner can be released back into the circulating air posing a potential health threat. Nordic Pure does not endorse this type of filter and does not sell reusable filters.
Make-Your-Own Air Filters are designed to enable you to construct your own filter. Buyers for these types of media filters usually do so because their HVAC system does not accommodate standard sized air filters. The most common media for this filtration is fiberglass. The handling of fiberglass is difficult as fibers from fiberglass can break off in the skin causing discomfort. Further, fiberglass provides only marginal filter effectiveness. Too, the Make-Your-Own-Filters often have no frames to use in securing the media material. As a consequence, the filters can often collapse, necessitating a service call by an air conditioning professional. Nordic Pure does not endorse the use of this type of air filters. Our many years of manufacturing expertise have enabled us to manufacture a custom air filter at about the same price as off-the-shelf air filters from competitors. The most significant difference is that the media material is much higher in quality, is available in all MERVs. The internal filter media is attached to a quality frame, with support material, ensuring there are no collapsed air filters.
Disposable Panel Air Filters are the most commonly used type of air filter in furnaces, air conditioning systems or HVAC systems. Panel air filters, being disposable, solve the problems associated with handling dirty air filters while ensuring ease of removal/replacement. Disposable panel air filters use a variety of media for filtration. A “panel” air filter gets its name because the air filter is actually manufactured as a self-contained, one-piece “panel” that consists of the (a.) air filter media material (b.) any internal structure that supports the air filter media material such as metal fabric, wire or even cardboard, and (c.) the box or frame in which the air filter media material and the media support material is attached to and housed within. The box or frame of a Disposable Panel Air Filter is rigid. The frame is normally constructed of cardboard, plastic or metal and made to withstand the insertion of the filter into the HVAC system and keep its structural integrity while the HVAC system is operating. The frame is defined by the length, width and thickness of the box housing the air filter media.
Fiberglass Air Filters are panel air filters that use fiberglass as the filter media. Fiberglass filters are very cheap and only remove the largest of airborne particulates. In addition to its limited ability to filter finer particulate, fiberglass is very brittle and can cause harm when handled. Further, there is a potential for the fiberglass fibers to break off and enter passing air, creating a serious health problem. Nordic Pure does not endorse the use of fiberglass air filters, both because of their limited ability to filter the air, especially smaller particulate, and the health implications.
Pleated Air Filters are much like Disposable Panel Air Filters in that the filter media is housed in a rigid panel but the difference is that the media material used to filter the air, as well as the way the material is mounted into the air filter box or frame, is different. The filter media used in pleated filters most often resembles fabric and has the capability of removing significantly smaller particulate from the air. Further, when the filter media is integrated into the air filter, it is pleated to provide more surface area for filtration. This pleating more than doubles the surface area of un-pleated filters. The net effect is that you end up with an air filter that removes more of the particulate in the passing air AND has at least twice as much surface area. Pleated air filters provide a significantly higher level of filtration.
Electrostatic Pleated Air Filters are a more highly evolved version of the pleated air filter. In addition to a higher quality media filter material, and pleats for increased surface area for filtration, Nordic Pure air filters are also “electrostatic”. This means that our filter media material is electrically charged so that the media material acts much like a magnet to draw more particulate into the media filter material for more efficient filtration. Another benefit of the electrostatic material is that it does not permit the growth of bacteria, often a problem with other air filters. Nordic Pure manufactures and sells only Electrostatic Pleated Air Filters in a wide variety of lengths and widths with thickness from 1” to 5”.
In an effort to aid the consumer in determining the difference between the qualities of one air filter compared to another, the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) developed a rating system called the MERV Rating.
MERV stands for Minimum Efficiency Reporting Value. ASHRAE assigns a MERV number intended to help people compare air filters that are for use in heating and air conditioning systems. The MERV rates the efficiency of the air filter on the first day of use, regardless of whether it is used as an air conditioner filter or furnace filter or a HVAC system that combines both heating and air conditioning into one HVAC system. The MERV rating ranks air filter efficiency by assigning a number ranging from 1 to 16, with one being the lowest air filter efficiency and 16 the highest air filter efficiency when used in an HVAC system. MERV 16 is comparable to a HEPA filter.
Particles in the indoor air, which pass through the HVAC System air filter, are measured in microns, which is 1/1000 of a millimeter. A human hair is about 100 microns wide. Regardless of the purpose, whether it is used as air conditioning filter or furnace filter or used in a combination HVAC system, Nordic Pure air filters capture airborne particles as small as 0.3 microns!
We manufacture most any size A/C or furnace filter in 1”, 2” or 4” thickness. Call into Nordic Pure 800.590.0339 and give your dimensions and you are given a firm quote within seconds of entering your air filter information. The printed size on the side of your air filter 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 air filter within 1/8 of an inch on the length and width. Consult your HVAC system’s operating manual for information. Custom air filters are not refundable or returnable so please make sure you order the correct size. Our website calculator for custom filters will give all MERVs but not with the carbon option at this time. To get an approximate price for a custom “plus carbon” filter, please look for the next size up standard filter (plus carbon). Contact us at firstname.lastname@example.org for a custom, plus carbon, quote.
Air conditioner furnace filters in most homes are generally located behind an air intake grate in your home’s walls, ceiling, basement or attic. These generally look like large vents, but the air flows into them, rather than out of them when the heating or cooling system is blowing air. They may also be located in or near the air conditioner or furnace. Many homes may have more than one, and they may be different sizes. If you can’t find your air conditioner system filter here are some places to look:
At the central air return register, grille located in a wall or ceiling if your system uses centralized air returns instead of individual room-air return ducts. There may be several central return points, depending on the design of your system. If there are more than two, chances are the filter was placed at the air handler instead of at these grilles. Unfortunately that means that the return ducts themselves become more soiled with dust and debris from the building.
At the air handler, look for a slot which has a removable cover. The slot may be just an inch or so wide if 1″ thick filters are used, or it could be several inches wide if a wide high-capacity pleated or similar filter was used. The return air plenum on an attic or basement air conditioner blower unit will usually be a large metal enclosure about the same dimensions in width and height as the air conditioner blower unit itself. Look for a filter slot right where the return plenum contacts the blower fan assembly.
At a basement air handler we also look for an air filter at the return air plenum which is often next to the bottom of the air handler if the system is an “up-flow” unit (or vice versa for the less common case of return air entering at the top of the air handler and exiting at its bottom).
Next to an electrostatic air cleaner: if your air conditioning air handler has an electrostatic air cleaner installed, look for the air filter, if there is one, next to the electrostatic air cleaner. In addition, the electrostatic air cleaner, which is a type of particle incinerating filter itself, needs to be removed and cleaned periodically. Check with your unit’s manufacturer for cleaning interval and procedures. Often the electrostatic unit can be cleaned inside a dishwasher. Often there is also a thin metal washable air filter installed along with the electrostatic air cleaner.
We recommend you check your HVAC system’s manual for additional information.
*Make sure you find all of the filters as some systems have multiple filters and even multiple types of filters installed, such as a fiberglass or pleated paper filter, a washable filter, and an electrostatic air cleaner. These last two are cleaned, not replaced, when they’re dirty.
Change your air filters every month when the air conditioning system is in operation but make sure the system is turned off when you actually replace the air filters.
(Air Filter Accessibility: Air filters which are hard to access are rarely changed as often as necessary. I frequently see HVAC systems designed by someone who obviously has never had to service them. Placement of filters and air handler access doors in very hard-to-access locations such as at the far end of a minuscule attic behind a forest of trusses means that the system is very unlikely to receive the periodic inspection and maintenance it needs. I prefer to see A/C and heating filters placed at the building side of the air return register or grille, so as to protect the return duct from debris accumulation.)
Your air conditioner furnace filter’s size is measured by the width x length x thickness in inches. For example, a pleated air filter that is 20x25x1 means 20 inches wide by 25 inches long by 1 inch thick. The actual measurements of each air conditioner furnace filters are usually about half an inch less than the listed size. The actual size of our 20x25x1” air conditioner furnace filter is 19 ½ x 24 ½ x ¾”. This is normal. Most air conditioner furnace filters have the Nominal and ACTUAL size printed on them. But if they don’t you will need to measure them in order to get the exact size. On the larger 4” and 5” filters each HVAC unit manufacturer may have slightly different exact dimensions, even if they all have 20x25x5 printed on them. Measure to be sure you are ordering the correct filter. Our filters may vary up to 1/8 of an inch due to the nature of the air filter manufacturing process.
Generally every 2 – 3 months, but you may want to change them more often. During periods where you are using your HVAC system continuously, we recommend changing monthly to maintain the best indoor air quality. The following chart should assist you:
Recommended filter change intervals:
Multiple Furry Pets
Heat/AC Fan – Mostly On
Windows/Doors – Open Often
One Furry Pet
Heat/AC Fan – Moderately On
Windows/Doors – Sometimes Open
Heat/AC Fan – Mostly Off
Windows/Doors – Usually Closed
“The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace your air filters […] air conditioner furnace filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house.” – United States Department of Energy
Look for the arrow showing airflow direction on the old air conditioner furnace filter and remember which way that it points. Make sure that you turn off your HVAC system to stop the airflow. Remove the old air conditioner furnace filter and discard it carefully so you don’t put the dust and other airborne contaminants back in the air. Write the date you install the air conditioner furnace filters on the place indicated on the side of the air filter frame. We strongly suggest you take the time to check your air filter from time to time to make sure it is not clogged. Remember, the pollutants you see on a dirty filter could be airborne particles you breathe – Change your air filters regularly and use our FREE Reminder Service to help you! Simply log into your account and select the Preference you would prefer for your Reminder Service. Or you may make your selections when filling out your information as a new customer.
Look for the arrow showing airflow direction, and install the new pleated air filter so the air flows in the direction of the arrows. Many air conditioner furnace filters are located at air return vents, where the air flows into the wall or ceiling. Note: On some custom size air conditioner furnace filters, the arrow may not be visible. If so, the air flows from the side without the metal mesh through to the side with the metal mesh.
Your 1/2″ Ring Panel will have two sides. One is a fuzzy, high-loft texture and the other is a smooth texture. The air enters thru the fuzzy, high-loft side and exits out the thinner, smooth side.
Nordic Pure air filters do not kill germs, however, the material our air filters are made of 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. Odors are most often a combination of gas and particulate. Air passing through Activated Carbon will chemically alter gases that cause odor. Nordic Pure Plus Carbon air filters are available for all pleated air filters. This product is a regular pleated air filter, with a thin layer of filter media that is permeated with 74 grams per square yard of Activated Carbon. Particulates produced by tobacco smoke or a burning fireplace will be filtered out by the MERV rated air filter, then the air passes through the Carbon layer and odors are neutralized (gases exchange molecules with the activated carbon and are neutralized). The Carbon layer is always on the outflow side of the air filter.
Nordic Pure air conditioner furnace filters can reduce many common airborne allergens far more effectively than ordinary air filters: Up to 97.8% reduction for pollen and other major allergens and irritants flowing through the air filter.
Better filtration is important to improving indoor air quality that can lead to better health. Dust, pollen, mold spores, animal dander, lint, bacteria, and dust mites and dust mite feces are some of the airborne pollutants we inhale in our indoor air without proper filtration.
These airborne particles can result in sinus congestion, sore throats, asthma, allergies and many other symptoms.
Our 1” filters come in boxes of three, six, twelve or twenty-four. The 2” air filters are boxed in packs of three and twelve. The 4” and 5” air filters can be purchased in boxes of one, two, and four. Quantity discounts are automatically computed in the shopping cart, so be sure to try greater quantities to compare prices.

Virtually all apartments provide air filters for their tenants. Normally, cost is the primary consideration given to air filters for HVAC systems. As a consequence, you are not likely going to get the best air filtration possible. We recommend you contact the Property Manager and explain your desire to obtain a higher-quality filter in your HVAC system. If they are unable or unwilling to supply the quality of air filter you desire, ask and obtain permission to supply your own before ordering our air filters. Once you receive approval, place your order. Anything you can do to extend the life of your HVAC system is in your best interests. If a maintenance person installs your air filters for you, we suggest you notify them of the location of your replacement air filters and make them accessible.
Dust is actually a combination of dirt, pollen, hair, dead skin, pet dander, dust mites, dust mite feces and a myriad of microbiological pollutants. Though there is no way to completely eliminate dust, you can control the dust with adequate filtering of the air through your HVAC filter. Choosing the right filter media enables maximum filtration without taxing your HVAC system. Our MERV 12 air conditioner furnace filters remove up to 97.8% of pollen, pet dander, dust, mold spores, dust mites, tobacco smoke and other airborne particles, therefore helping to reduce the amount of dust while providing a more healthy indoor environment .
Though we touched on the subject at the beginning of the FAQ’s, you will find this is no longer a popular option as the handling of messy, used filters combined with the cleaning process turns off most people. Reusable filters must be cleaned and maintained as much as 2-3 times more frequently than disposable pleated air filters. Pay special attention to the removal of all moisture before reinserting the reusable air filter back into the HVAC system. Presence of moisture can produce mold and attract bacteria.
Nordic Pure MERV 12 filters have a low air flow resistance for residential and commercial heating and cooling systems. Air flow is generally measured as a difference in air pressure on each side of the filter, measured by an instrument that uses water in a measured column to show air pressure. The higher the pressure difference, the more the water in the instrument moves. Its movement is measured in inches. The more inches of water moved, the more the pressure difference. This is called air flow resistance.
The more efficient an air filter is, the more it tends to resist air flow. However, our MERV 12 air conditioner furnace filters provide only a few fractions of an inch more resistance than ordinary air conditioner furnace filters that are much less efficient at removing particles from the air. Our MERV 12 – 1″ air conditioner furnace filters have a low resistance of only 0.26 at 300 feet per minute of airflow, which works fine with virtually all systems.
Fiberglass air conditioner furnace filters are designed only to capture large particles and to protect your heating and air conditioning system; they do nothing to remove smaller particles like many allergens. These types of air conditioner furnace filters also have either no MERV rating assigned to them or in some instances, have a MERV rating of from 1 to 4. Nordic Pure anti-allergenic air conditioner furnace filters not only protect your HVAC system from dust, and other airborne particles, Nordic Pure air filters remove up to 97.8% of the pollen, pet dander, dust mites, mold spores, tobacco smoke and other airborne particles in the indoor air. Since the average person spends 2-3 times more time indoors than outdoors, it is the healthier choice.
You should not use more than one filter in any one place in the HVAC system due to the air flow restriction it imposes on the HVAC system. Consult your service manual regarding specifications for your particular furnace or air conditioning system.
Nordic Pure manufactures all of our air filters using a filter media that contains a permanent electrostatic charge causing dust to cling to the air conditioner furnace filter using the same principle as static electricity. As a consequence, our air filters are far more effective and efficient than traditional pleated filters. Nordic Pure does not endorse or sell the permanent metal electrostatic filters.
We have quantity discounts available for businesses ordering more than 100 furnace filters / air conditioner filters per month. Please email us at: email@example.com for a quote.
As effective as our air filters are in controlling airborne particulates throughout the home, it is simply impossible to rid your indoor air of all the potentially harmful particulates that could be present in your indoor air. As a result, we strongly suggest adding an air purifier to various areas of your home where odors or allergens are most likely to accumulate. For example, small portable air purifiers placed in strategic areas. Laundry rooms, pet rooms, and bathrooms are all excellent places to locate an air purifier. Air Purifiers help neutralize odors and provide additional filtration. We are experts in air purification technology and offer only products we have tested extensively and are known for their effectiveness. For more information and to see our selection of air purifiers, go to: http://www.nordicpure.com
According to the American Lung Association, in 1999, 85% of Americans did not realize the air in their homes might be a health hazard. However, more people are becoming increasingly aware of the importance of the quality of air that we breathe indoors. We take for granted the cleanliness of our indoor air. The average person spends 90% of their time indoors, be it at a store, bank, school, etc. Therefore, making it vital to our health that we are informed on improving our indoor air quality.
Asthma, allergies, and other respiratory problems are affecting millions of people, and are on the rise. It is no wonder that researchers are studying the effects of indoor air quality on these ailments. In a 1996 survey, it showed that in 58% of homes at least one humidity-related or respiratory problem was present in the form of allergies, asthma, persistent coughs, and/ or nasal congestion. In 36% of the homes, at least one household member suffered from at least one respiratory ailment.
The increased awareness for a better indoor air quality has prompted changes in building codes, and development of products to maximize a healthier indoor air quality. Removing and/or containing the harmful particles and odors protect the home and provide a higher quality air for the entire family. Taking control of the quality of health environment in which you live and work in is the first step in improving your life. Finally, you can “breathe pure”; it is definitely worth every breath.

The Nominal size (nominal = name) of a filter is listed by its length, height and thickness. For example, a common filter size would be listed as 20x20x1. 20 inches wide by 20 inches high and 1 inch thick. Its “Actual Size” is very important! Our 20x20x1 is actually 19 ½” x 19 ½” x ¾”. You might want to measure your old filter, just to be certain of the filter’s actual dimensions.
In our factory, we hand assemble all of our air filters, using only one MERV filter media at a time. If we are assembling MERV 12, then only MERV 12 are boxed and marked as MERV 12. The same goes for all of our other MERVs. If you ordered a MERV different than 12, you ought to have a colored sticker on the seal of the box, as follows:
MERV 7 – gray
MERV 8 – purple
MERV 10 – yellow
MERV 11 – rose
MERV 12 – blue (most common MERV; often has no sticker)
MERV 13 – green
MERV 14 – teal
15 – orange
Our clean, white templates, or outer cardboard frames, are kept non-specific to save on manufacturing cost. That’s why they are not stamped or labeled individually.
Our 1” filters only come in boxes of three, six, twelve and twenty-four filters. It’s one of several ways we keep our prices so low, per filter. The 3″, 4”, 5 and 6” filters are sold separately, however.
Our pleated filters have, on average, sixteen pleats per foot..
By code, the vent-less, heavy, fitted AC Covers are required to allow for ventilation by leaving the bottom of the coils open to air. This reduces condensation and protects the unit (and your home) from damage if the unit is accidentally turned on while covered. The upper deck, fan, coils and electric components will remain free of dust, debris and water. On the other hand, our ready-to-ship covers are made of lighter weight fabric and have hooded vents midway up two sides of the unit. They also have a drawstring at the bottom and a looser fit around the unit, depending on measurements.
Activated carbon is nontoxic and is useful in many different industries. From medicine to water purification, carbon is a highly effective method of removing and preventing unwanted chemicals. In Nordic Pure Air Filters, carbon removes chemical buildup in recirculated, filtered air.
Nordic Pure’s carbon filter media is non-woven polyester impregnated with finely ground carbon coatings, and heat-set to retain those coatings even if the media is rinsed or vacuumed. It will not flake or leave carbon dust in the air. A highly porous charcoal product, our activated carbon is derived from the carbon source coconut shell. It’s “activated” by a process that uses oxygen to open up millions of small pores within the carbon grain structure. Our activation process does NOT use hazardous chemicals. We are not targeting any specific contaminant, since we want a broad spectrum adsorption capability. Volatile Organic Compounds (VOC’s) and gaseous odors are adsorbed, or bonded, to the large amount of surface area inside the carbon grains. Just imagine: one teaspoon of activated carbon granules has the same surface area as a football field! That teaspoon can absorb nearly 60% of its own weight in gaseous odors! Nordic Pure carbon media has 74 grams per square yard of activated carbon, with a total coated weight of 5.2oz per square yard.
The adsorption process does not affect pressure drop because gases are adsorbed inside the carbon media and do not build up on the outside. However, air velocity, humidity, temperature and the shape of odor molecules will influence the odor elimination process and the life expectancy of the activated carbon. At times of high odor generation, your HVAC’s fan feature should be used to recirculate air through the media.
Nordic Pure’s Baking Soda air filters are made with an unscented baking soda media – and a sturdy beverage board frame with a wire mesh backing. It’s the pure baking soda air filters that help control, absorb and neutralize odors from pets, smoking, cooking and other unwanted odors. The electrostatic media attracts airborne allergens, dust, pollen, mold spores, pet dander, dust mite and other airborne contaminants and is a Merv 8 rating.
Your carbon air filters will adsorb the odors that are pushed through the filter media. The boxes we use are clean and dry, so outside smells should not permeate enough to influence the new carbon. The capacity of our carbon is extremely high and will most likely outlive a 1” filter’s use.
SEER stands for “Seasonal Energy Efficiency Ratio”. SEER ratings are set by US law and regulatory entities. The SEER is defined as the ratio of total cooling output (in British thermal units, or BTU) to the total energy consumed (in watt hours) during the unit’s normal annual usage period. As a general rule, higher SEER is more efficient and will save energy costs in the long run.
