14 best air filter for acs

Product description

You run a tight ship at home, from floor to ceiling and everywhere in between. Unfortunately, ordinary home non electrostatic air filters aren’t super effective at capturing unwanted particles. The good news: The unique design of the electrostatically charged Filtrate Basic Dust and Lint Air Filter attracts and traps more particles from your air through your heating and cooling system, making quality control a breeze. With each cycle through the filter, your indoor air becomes a little bit cleaner.

From the Manufacturer

The Filtrete Dust Reduction Filter attracts and captures household dust and is ideal for high-velocity equipment. For residential use only.

• Outperforms fiberglass, washable and non electrostatic 3 month pleated 1 inches air filters for your furnace, air conditioner, or HVAC system
• Exclusive Filtrate Brand 3 in 1 technology from 3M traps unwanted air particles, while letting cleaner air flow through
• Attracts and captures large particles such as lint, household dust, dust mite debris and mold spores
• Filtrate 300 MPR (Micro particle Performance Rating) equates to MERV 5
• For optimum performance, change your home air filter every 90 days or sooner
• For residential use only
• The higher the MPR, the more micro particles; such as pollen, pet dander, smoke, bacteria and viruses, your filter will capture from the air passing through it

User questions & answers

Question:	Why do mine come out black after a relatively short amount of time
Answer:	Hello - Particles can darken the filters. For example, burning candles can cause blackening of the filter. We would be happy to further discuss this with you, please connect with us directly at 1-800-388-3458 M-F 8am-5pm CT.
Question:	The product description lists 2 sizes- 14x24x1 in large font and 14x14x1 in small font. Which size will I receive? What are the actual dimensions
Answer:	I received 14x24x1, but they were tough to install
Question:	Are these UV resistant
Answer:	Thank you for asking. No. If you are having a UV light installed into your system the light should not be able to reach this filter. If you have a UV light already installed and it is near the filter intake, we do not recommend using Filtrete Filters.
Question:	What is the merv rating
Answer:	Thank you for asking. These filters are a MERV 5.

User questions & answers

Question:	Does this filter have wire reinforcement on the front and the back
Answer:	I swear, I know of another website that has masks that are cheaper, breathable, 100% cotton, cleanable, reusable, adjustable ear straps, and most importantly, they have filter bags. Masks for children are available. Hoping to help people in need. Gõõglẹ sẹạrch >> gõsbüy
Question:	In what country are they made
Answer:	Can't find an answer to your question. I looked all over the filter and no country of origin is stated.Maybe on the outer wrapper of the set but that was long ago removed and discarded.Sorry but no answer.
Question:	Discribtion says $4.00 a pack which leads you believe there are serveral filters included. I only received 2 filters so that makes them over

Question:	Is filtrete allergic to using the better known merv rating system
Answer:	I am not sure I fully understand your question. When it comes to merv rating you need to balance your filter needs/wants vs efficiency. The higher the merv the smaller the particles filtered, but the higher your power use as your air handler has to work harder to pull through the finer filter. According to the USGBC LEED standards, a minimum of merv 13 must be used for all recirculated air.Merv 6 = 300 mprMerv 8 = 600 mprMerv 11 = 1000-1200 mpr (this filter)Merv 13 = 1500-1900 mpr.I chose this filter because it seemed like a reasonable compromise of filtration, efficiency and cost.I hope this helps. :)

User questions & answers

Question:	How many pleats per foot
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:	Filtrete has 40 pleats per foot. The more pleats, the more filter is being used in the product and the more surface is available for removing crap
Answer:	I swear, I know of another website that has masks that are cheaper, breathable, 100% cotton, cleanable, reusable, adjustable ear straps, and most importantly, they have filter bags. Masks for children are available. Hoping to help people in need. Gõõglẹ sẹạrch >> gõsbüy
Question:	does this product contain any fiberglass and can it be used in mask filtration
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.
Question:	Excuse me .. what it merv means
Answer:	...Griffen, he was the original o.g, the triple diple o.g, the double o. capital .g, the Ompa Oprah talk show host of his time! HEEEERRRRRRREEEEE'SSSSS...MERV!! I'm just kidding! It stands for; "Minimum Efficiency Rating Value" There are 1-16 ratings with "1" being the worst and " 16" of course being the best! I tend to get the MERV11 in a 4" thick pleated filter because it traps everything I'm most worried about like dust, mites, pet dander, bacterias, allergic pollen and when my daughter cooks or burns something in the oven, kitchen smoke! Keeping all that "sheet" out of the distribution process of hot/cold air being deposited throughout the many registers in my house not only protects my family, but it helps to prolong the system and house by keeping it all clean and dust free!! Don't skimp when it comes to selecting that MERV rated filter or you may end up replacing more than just the filter. Read the specs on the system you own to be sure you're using the correct size filter and change it every six months or less depending on your environment.

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:	does your filter slightly bow inside the air return? Is that ok
Answer:	Depends. When air is moving through the filter, it normally bows slightly, moreso over the weeks as it clogs up. When it is new and air is not moving, it should not bow, because that would mean it is not fitting. When mine bows like that, it means it got caught on a screwhead, and I use the end of a crowbar to shoehorn it over the head, and it straightens out. However, even if it doesn't fit a little bit, as long as the 4 edges have a good seal, bowing will not affect performance.

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.

• Actual Size: 19 1/2 x 24 1/2 x 3 5/8 (19. 5 x 24. 5 x 3. 63)
• Attracts indoor allergens, dust, pollen and other airborne contaminants.
• Hypoallergenic and pleated electrostatic filter material. Lead/Handling Time - 5
• Nordic Pure recommends changing 4" air filters every 3-6 months
• Proudly Made in the USA

User questions & answers

Question:	Title of page says Merv 15, but description say says Merv 12, seems shady
Answer:	Thank you for bringing this to our attention. We are in the process of updating our descriptions and this will be corrected. This furnace filter is a MERV 15 Plus Carbon, box of 2. We appreciate your business!
Question:	I would like to know why these filters are made smaller than advertised, so the unfiltered air could get passed the filter
Answer:	In fact some type of Furnace use the smaller 20X25X4 filter, I was happened got such type of carrier' furnace, I went to Homedepot and bought the standard size 25x20x4 and found the filter was bigger than the slot and can't be inserted. So you must be careful and check the real size of the filter, do not think 25x20x4 are all same size. They are NOT!
Question:	Received 2 filters in plastic wrap with no markings of actual merv count. how do i know this correct filter i paid for
Answer:	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 production facility in Alabama shrink wraps all the filters prior to shipping and boxing the filters. They will sometimes have a product insert inside the shrink wrap. Our production facility in Oklahoma does not shrink wrap yet. On our Nordic Pure blue & white boxes, you should have the MERV rating label located on the side of the box above the shipping label. 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.

User questions & answers

Question:	Are these made with Fiber Glass
Answer:	I have not torn one apart to look.
Question:	Hi are these filters individually wrapped in plastic
Answer:	Not each filter. It does come wrap the 6 pack.
Question:	What is actual size of 14x14” filters
Answer:	14"x14"
Question:	does it restrict the air flow compared to regular filters
Answer:	Any increase in "merv" rating reduces the air flow. HVAC systems have a tolerance level. You should work within that level. You have to gage via technical measurement or manufacturer specifications. Everything is a compromise. More filtration is less flow. No filtration highest flow. Choose your poison and gauge your cost benefit. You want lots of dirty air or just enough clean filtered air.

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.

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!

Answer:	As previous person said, it can be used in a furnace or in a grill (ceiling, wall, ...).

User questions & answers

Question:	does anyone have a whistling sound coming from air duct
Answer:	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.
Question:	What’s the model number
Answer:	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
Question:	do the number of pleats really matter
Answer:	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.
Question:	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
Answer:	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.

User questions & answers

Question:	smoke smell
Answer:	I do not know, I do not smoke. Keep in mind a lot of scents are embedded in the fabric of furniture, carpets, etc. All this is doing is filtering the air. I would still give it a shot though because it does work well for pets.
Question:	what is the MERV rating
Answer:	what is a MERV rating
Question:	I purchased 6 of these filters less than a year ago for $58, why has the price been increased by almost
Answer:	It is (2) packs of two filters. Total of (4) Says $16 per twin pack next to “add to cart” price. So this deal is actually cheaper than what you previously paid. Basically $8 each instead of nearly $10 each
Question:	air flow direction - always thought the black carbon was the first layer from the intake - but doesn't show like that on package
Answer:	The carbon particles are on the back side, yup, and they fall off. Do yourself a favor and buy a different filter and then buy one of these https://www.amazon.com/gp/product/B000U204W2/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 (which are very good by the way). The filter you are asking about also seems to have a very mild odor (maybe from the glue they spray on to hold the carbon particles on, not sure). The filter material itself is also almost like hair or fiberglass or something - suffice to say the whole design of the filter is just comically bad if you asked me. I tried installing the filter backwards (carbon side out) but the filter material started coming off and being sucked into the air duct. As mentioned, the carbon particles fall off all over the place, even with gentle handing of the filters. From an engineering standpoint, this filter is an absolute disgrace and should have never made it past even the R&D stage. I highly doubt much of the carbon or whatever they have attempted to adhere to the backside is doing much. An inexpensive carbon filter pad and a traditional replaceable filter work far, far better.
