User questions & answers

Question:	The description states "filtrete micro allergen defense filter, mpr 1000..." but the picture shows mpr 1550....which one are you buying
Answer:	What size filter are you looking for? This listing has 3 choices - both of the choices that have a description of mpr 1550 are actually called allergen reduction filters & clearly state that they are mpr 1550. I use one of these sizes & always get the 1550. If you need 16X25X4 it's called allergen defense filter mpr 1000. I couldn't find any other statement in the description that listed the mpr - so to me it's unclear. You might want to contact amazon customer support to verify the mpr, but also, the product can be returned if it's not what you were looking for.
Question:	What are the dimensions of the filters? The product image shows 4" deep (20x25x4), but the option is only 1" deep (20x25x
Answer:	The one I purchased was 20x25x4. If you only have option for 1 inch thick, then it sounds like they are out of the 4 inch version.
Question:	Never had an air conditioner or furnace so I have a rather silly question. How can I tell when the filter needs changing - dirty on the backside
Answer:	When it gets dirty on the air intake side. Don't wait for it to get caked with dust as this will cut down on air flow and make your furnace/air conditioner work harder to reach your desired temperature. Filter vendors often recommend changing 4 times per year, but your mileage may vary depending on how much you heat and cool and the cleanliness of the air being moved. I change about 3 times per year, but I could go to twice. Do you change your car filter? How dirty does that get? Be sure the actual size of the filter is correct for your blower. Filtrete nominal sizes and actual sizes differ. I got stuck with 4 filters I can not use. I bought the size 16x25x4, but the end of the filter has the actual size: 16 x 24 1/2 x 4 1/2. the 4 1/2" dimension is too large to fit.
Question:	what is the Merv Rating and how do you convert 1550 MPR to a Merv rating
Answer:	While I am not sure the Filtrete Allergen Reduction Filter is exactly the same as the Filtrete filter shown in the following commercial website, the table shows a MERV of 11 for a MPR of 1500. All the products seem to be 1" rather than 4." I don't know if that affects the MERV. http://www.iallergy.com/filtrete-air-filter-comparison.phpThe bottom of this commercial website page also describes the relationship of MERV, MPR, and FPR ratings for AC and furnace filters:http://www.bestfilters.com/AC-Furnace-Filters_c_605.htmlBased on my reading of the table, a MERV of 11 seems consistent with MPR of 1550.

The Filtrete 2200 MPR Elite allergen reduction filter not only vastly improves the air quality in your home, it also keeps your air conditioning and heating systems running efficiently, saving on utilities and maintenance costs. The electrostatic filter attracts and captures airborne dust, pollen, dust-mite debris, lint, mold spores, pet dander, smoke, smog, bacteria, particles that can carry viruses, and particles that carry odors. With each pass through the specially pleated filter, the air in your living space improves, making for a healthier home environment. This high-performance filter outperforms comparable non-electrostatic fiberglass and washable and reusable one-inch filters.

2200 MPR Elite Allergen Reduction Filter At a Glance: Electrostatic filter attracts and captures dust, pollen, and other particles that can be harmful to your health Improves air quality by cleaning air with each pass through the filter Keeps your furnace or air conditioner running efficiently Outperforms comparable fiberglass and washable/reusable filters Pack includes six filters

The Elite allergen reduction filter's fibers attract air-polluting contaminants (view larger).

By removing dust from the air, the filter also reduces strain on your furnace and air conditioner, helping to keep them running efficiently (view larger).

Electrostatic Design Captures More Particles

The 3M Elite allergen reduction filter is made with both positively charged and negatively charged fibers that act like tiny magnets to attract air-polluting contaminants. Since particles in the air are either positively or negatively charged, they are attracted to and captured by the filter and kept out of your living space.

Electrostatic filters, including the 3M Elite allergen reduction filter, perform better than comparable non-electrostatic fiberglass and washable/reusable filters, because they attract and capture the small, allergy-aggravating microparticles that non-electrostatic filters can't.

Improves Indoor Air Quality

With indoor air a surprising two to five times more polluted than outdoor air, the 3M Elite allergen reduction filter can make a difference in maintaining a healthier home environment by cleaning air with each pass through the filter.

The 3M Elite allergen reduction filter features a 2200 Microparticle Performance Rating (MPR), which means it is able to capture large and small particles from the air, including household dust, pollen, dust-mite debris, mold spores, pet dander, smoke, smog, bacteria, particles that can carry viruses, and particles that carry odors. This high-performance filter meets the American Lung Association of the Upper Midwest Health House Program's indoor air quality guidelines.

Improves Efficiency

This high-performance allergen-reduction filter also keeps your heating and air conditioning equipment working efficiently by removing dirt and reducing strain on the motor. It is recommended that you change the filter every three months. However, the effectiveness and life of the filter can vary and depend on the individual conditions in your home.

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.

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.

User questions & answers

Question:	Is this 2 two packs for a total of four filters? Or two filters total
Answer:	TWO PACKS means TWO . You must check the box stating how many filters you wish to buy, either 2 or 4 or 6. Hope this helps!
Question:	Has anyone experienced any issues with blower motors going out due to the merv 13 restricting air flow? my hvac guy said it happened to his customers
Answer:	No, I have never had a motor fail in my home, and I've used a high MERV filter for several years. I had a starting capacitor fail, but I think that was a faulty cap. (capacitor plague), and not over heating due to poor airflow. A clean higher MERV filter is probably going to allow more air flow than a dirty low MERV filter. Closed up registers and dirty trunking are also going to contribute.
Question:	where can i find the static pressure chart including airflow as well as pressure drop
Answer:	The credit goes to the gentlemen who posted the answer in https://www.amazon.com/gp/customer-reviews/R1N62EHZET52S7/ref=cm_cr_arp_d_viewpnt?ie=UTF8&ASIN=B00TUDHPQK#R1N62EHZET52S7 The complete response from 3M below: Generally speaking, for most residential HVAC systems, the filter will become restrictive when it reaches a .5 pressure drop. All of our filter media fibers are polypropylene and polyolefin plastic which will remove particles that measure 3 to 10 microns. Microparticle Performance Rating (MPR), MERV Ratings, and pressure drops are as follows: Elite Extra 2400 3-10 microns - 96% MERV 13 pressure drop .21 Elite Allergen 2200 3-10 microns - 94% MERV 12 pressure drop .18 Maximum/Ultimate Allergen 1900 3-10 microns - 93% MERV 12 pressure drop .16 Allergen Deep Pleat 1550 (4"). 3-10 microns 97% MERV 12 pressure drop .12 Ultra Allergen 1500 310 microns - 90% MERV 12 pressure drop .15 Odor Reduction 1200 3-10 microns - 85% MERV 11 pressure drop .24 Micro Allergen 1000 3-10 microns - 80% MERV 11 pressure drop .21 Dust & Pollen 600 3-10 microns - 65% MERV 7 pressure drop .20 Dust Reduction 300 3-10 microns -35% MERV 6 pressure drop .20 Flat Panel 3-10 microns -5% MERV 1 Pressure Drop .08 Pressure drop is a measure of air flow resistance. It is measured by inches of Water Column (W.C.) at 300 feet per minute (FPM). Clean/new filters are not restrictive to air flow. Filters will become restrictive if they are not changed when needed. A filter's life is actually determined by the user's living conditions and will vary for every user. Generally speaking, we recommend changing filters approximately every 3 mo nths. To determine when the filter needs to be change, we suggest holding it up to the light. When you cannot see light through the filter, it is ready to be changed, even if it is before 3 months. If you are concerned about airflow, you might want to use the filter with a lower pressure drop. If you have a high velocity furnace with high fan speed, you may need to change the filters more frequently, every 1.5 to 2 months.
Question:	Is this a single package of 6filters, OR is it 6 packages with each package having 6 filters
Answer:	It is a box with 6 filters in it. Normally these things retail for $19+ ea(Filter rating is 1900 by the way-as the packaging it came in did not state that although the Amazon description did).

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.

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.

User questions & answers

Question:	Which devices can I buy for this filter
Answer:	I'd call it white, if anything a slightly warm white. It has a slight texture - which could make it appear light gray due to any directional light.
Question:	Can it be vaccumed or washed
Answer:	got less flexible below 32degrees... but stayed together as long as substrate has same/similar coefficient of expansion/contraction
Question:	Can the filtrete hepa / allergen+ filters be cut down to fit odd size openings without diminishing effectiveness
Answer:	gets less flexible/supple...prone to fatigue cracking if bent or moved below freezing or cooler temps
Question:	Will this put too much pressure on the heating and air conditioning unit
Answer:	Yes. It has ridges, not flat. I used it on my potting she’d. Held up pretty well through the summer. Will probably have to touch reapply in the spring.

User questions & answers

Question:	do they have metal wires as shown
Answer:	I emailed asking about the sensor issue as both of mind that I bought in June of 2019 started doing this less than a year into it. Yes, sensors and filters have been changed. I never got a response:( It has been hard to get a response. Maybe it’s because I did it directly through the medify site. Customer service, How can I get our sensors fixed? see less
Question:	Where are these made
Answer:	This is a genuine HEPA 13 MedifyAir medical-grade filter. On Amazon, it is $66.99 and on our website, it is $69.99: https://medifyair.com/collections/filters/products/ma-40-replacement-filter-set.
Question:	What kind of debris will a new air filter capture
Answer:	If you have animals that shed or a lot of dust in your home it is every 2 to 3 months (AT MOST)that you HAVE to change it and it is very important to open it and check it every couple days because the filter gets clogged with hair or dust and just starts blowing dirt and lint all over your house until you notice it's clogged😢
Question:	Will such a high merv rating be okay for my air handler
Answer:	See if Amazon has the option to notify you when they come back in stock. One way I have extended the life of filters for mine is to turn it off & remove filter from unit & use a soft duster to remove some of the debris & give it a little shake. Also use your soft duster to clean area where filter goes and also clean the front of unit. Maybe also have it run on low, this might help until they come back in stock Hope this helps!

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.
