Customer Reviews:
  • Great product
    We use these because the air quality in our area is not great. Combine that along with normal indoor air polution and it really helps to have such a good filter cleaning our air. It's worth the larger price if you have any kind of allergies or sinus issues at all!

    Additionally, we have a small child, so I like to make his air as clean as possible!...more info
  • Keeps the dust down/Great delivery time
    These really keep the dust and allergens down. DO NOT BUT CHEAP FILTERS EVER!!! You can buy less expensive ones but we have a new baby and we feel that a cleaner enviorment would be better. With all the kids with asthma out there we thought "what the heck, it can't hurt. Also I ordered the filters at about 10am ant they were on my porch before noon the next day. Thanks....more info
  • Breathe Easy
    Go to airnow.gov to see how your air is affecting you and your family. Protect youself, and especially your children, with the air filters. I lived in california and watched these filters turn black from polution after 30 days. Protect yourself and breathe easy....more info

  • the description is a lie. this is for ONE filter not SIX
    Day 1
    I just received my single filter on this order. Thanks for the 16.95 shipping charge. The filter is totally mangled. I will be posting bad ratings daily until I get a full refund. Right now I am cautiously optimistic of BuilderDepot's customer service efforts. We will see what the next day holds for them. I wish I could attach a picture so you all could see how pathetic the packaging is. It seems plain to me that the spent about 2.00 on shipping this product. Totally unsatisfactory.

    Oh and the description is a LIE. The price is for one filter not six.
    Day 2
    From BuilderDepot "I am requesting a shipper claim and when it is settled will refund."

    So now I have to wait for the clam????...more info
  • Way better than my old filter
    OK, you have to make a choice: Electrostatic or (like these) non-electrostatic filters. 3M makes both types of air filters. One electrostatic filters cost about the same as this 6-pack but it doesn't need to be replaced every 3 months. On the other hand, these filters are more effective. I made my choice and am happy with it. Compared to my previous filter, these are 10 times as good. With new filters, I didn't notice much loss in air flow but only time will tell what happens towards the end of their life....more info
  • Great Filter !
    For families with alergies, this is a must for your home. Helped my children and I deal with pollen season. This is a great filter!...more info
  • Great value
    Filters arrived when promised with minimal shipping charge. Even delivered they were cheaper than buying at my local Home Depot. Will use again!...more info
  • 3M Filtrete Ultra Allergen Filter 6 Pack
    Product is excellent--I definitely recommend another supplier, though. I ordered 2(two) 6-packs and received 2(two) SINGLE filters. I received a partial refund when I complained, but no concession that this was blatantly fraudulent product "promotion". The supplier blamed Amazon.com and Amazon.com blamed the supplier. Both regretted the "misunderstanding"....more info

  • Try the Advanced Allergen filter if you have allergies or pets
    My house uses forced air for heating. The disadvantage of such a system is that it distributes the dust in the air everywhere in the house. However, it is supposed to be possible to filter out the dust. Over the years, I have steadily increased the quality of the filter that I use for my forced air heating system. However, until now I have not noticed any obvious difference in my allergic reactions that seem to start with the heating season.

    There are two cats in my house. I have read that cat dander, tiny flakes of cat skin shed by the cats, is five times smaller than household dust particles. It stays in the air much longer than ordinary dust before it settles. Because of its small size it requires a more efficient filter to get it out of the air.

    Until this year, I have used of variety of filters with mixed results. However, this year, I started using the 3M Advanced Allergen Filters, the ones in the blue wrapper. These have a 3M Microparticle Performance Rating of 1500, but do not have a MERV rating listed. MERV stands for Minimum Efficiency Reporting Value and is a number from 1 to 12, produced from a test designed by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE). A higher MERV rating indicates better filter performance. 3M uses particle data between 0.3 and 1.0 micron size to calculate a Microparticle Performance Rating or MPR. The higher the MPR, the better the filter. However, higher rated filters cost more.

    Here are some of the Filtrete filters offered by 3M:
    Dust & Pollen Filter, Microparticle Performance Rating 600,
    MERV rating of 8
    Micro Allergen Filter, Microparticle Performance Rating 1000,
    MERV rating of 11
    Ultra Allergen Filter, Microparticle Performance Rating 1250,
    MERV rating of 11
    Advanced Allegen Filter, Microparticle Performance Rating 1500,
    MERV rating not available

    The difference made by the Advanced filter was immediately obvious. My running nose stopped running. I assume that the new Advanced filters must be taking out more of the dust in the air including the cat dander. I have not noticed a change in the speed of the circulated air. The additional cost of the Advanced filter is worth it if you have allergies or pets. However, if you are happy with a lower-rated and lower-cost filter, then you can continue using that one I suggest that you check Amazon and vendors on the web to get the best price. ...more info
  • Clean air, high air flow resistance

    Our family bought this filter to address some allegry problems in our children. We noticed immediate benefits in term of cleaner air, fewer particles, and less dust. It was a pleasant surprise.

    The downside of the filter is that in less than a month of average use (we live in the moderate climate of NW Oregon) the furnace failed to start due to restricted airflow. Replacing the filter with an standard fiberglass model resolved the problem.

    The furnace / house are new, ~10 years old, and the filters have been replaced 4 times/year.

    Despite the clean air benefits, I'll stop using these filters, as I fear the extra air resistance will burn out the furnace fan motor or cause other furnace problems. ...more info
  • Very effective, very sturdy allergen filter.
    The Ultra Allergen filters work great. My wife and I both have asthma and allergies, and we have a cat. These filters keep us from sneezing during the pollen and leaf mold seasons. The frame is made from very stiff cardstock, and the media is enclosed in a wire mesh. I've been using them for about 8 years, after a cheap fiberglass filter and a "premium" Lysol Elite filter got sucked into the furnace....more info
  • disappointed
    I haven't used this product. I ordered a pack of 6, but only one arrived and the end was crushed. The vendor,Bic, did credit it back to me, but I was disappointed that no explanation was made as to why I only received one....more info

    Review of 3M Filtrete - Ultra Allergen

    These are outstanding air filters, based on the lack of dust and clean air inside our house; the build quality of these filters; and the fact that they have such a high rating. We've been using these filters for about 10 years in a Trane heat pump system, with no issues.

    This filter has a 3M Micro-particle Performance Rating of 1250. "MPR" focuses on a filter's ability to capture the smallest particles between 0.3 and 1 micron. The higher the MPR, the more effective the filter is, and the more expensive. The "basic" Filtrete is the least expensive. These are near the top-end. Their highest filter is MPR rated at 1700, but costs about 1/3 more that this one, and I can't tell the difference; although someone with allergies probably could. See TYPES OF FILTRETEs after this review for more information.

    Ours is a two-story house with a basement. There are two returns in the system, high in the wall, one each on the first and second floors. Several years ago, to do an even better job of air cleaning, and to keep the inside of our ducts clean, I replaced both return grilles with a grille assembly that has a built-in "furnace" filter holder. We use 3M Filtrete Ultra Allergens in the system's air exchanger and at each of those returns. In other words, all air flows through two Filtretes, which has been no problem for our heat pump's air exchanger. (Since there's no gas or oil "fire", it's not called a furnace). With this setup, the 3 filters need replacement every six months. Before adding the two return filters, we replaced the single air exchanger filter every 2 months, so total filter cost is the same.

    One reviewer said: "little did I know the extra drag on the air flow would cause my Lennox Heat Pump to burn up." All filters cause some drag on air flow, but the only way that could become a significant drag is if the filter was very dirty, which would be the fault of the homeowner for not replacing it. In my setup, if a filter is overdue for replacement, it arches in the middle (from the air drag) towards the fan's suction, and the air whistles as it rushes around the filter. Dirty filters reduce the efficiency of heat pumps or furnaces, but claiming a heat pump "burned up" because of a high-efficiency filter's air drag, is a stretch. It's more likely that his contractor gave him that line to switch blame away from the Lennox equipment, which failed for another reason. I checked the Lennox web site, and they don't even mention disposable filters, which isn't surprising. Imagine Lennox Corporation warning customers not to use 3M filters because their equipment can't handle the stress.

    We don't have pets or allergies; we use these filters because they result in very clean indoor air.


    I did some research, and found that 3M makes three classes of disposable Filtrete 1" filters for heating and cooling systems, with various options within each "class"; 14 different Filtrete filters in all.

    - "High Airflow" MPR of 200 - 600; filter options:

    Basic, MPR: 200
    Dust, MPR: 400
    Clean, MRP: 500
    Dust and Pollen, MPR: 600.

    - "Air Cleaning" MPR of 700 - 1000; filter options:

    Micro Particle; MPR: 700
    Allergen, MPR 800
    Micro Allergen, MPR 1000
    Micro Allergen Extra, MPR 1000.

    - "High Performance" MPR of 1200 to 1700; filter options:

    Allergen, MPR 1200
    Ultra Pure, MPR 1250
    Ultra Allergen, MPR 1250
    Advanced Allergen, MPR 1500
    Ultimate Allergen, MPR 1600
    Maximum Allergen, MPR 1700...more info
  • A great filter!
    I have always used filtrete products, my new apartment has this odd size filter. None of the local stores carried a filtrete in this size. Thank you Amazon....more info
  • Very good
    I have no specific complaint with this product--it seems very good, but it does make me question if they will last 3 times as long as the cheaper ones. They may not be worth the high price premium. But it's good to know I have a good filter in my home. Amazon was great on delivery once again! I was glad to find this size because it was s difficult to find in retail stores....more info
  • It Works For Me...
    I have cats and an air return near the floor, so having a good filter is high priority. I've use Filtrete Ultra Allergen filters for 9 years, 5 years with an old A/C & Heat Unit, and the last 4 years with a new dual speed Carrier A/C & Heat Unit. I replaced my old unit before it died, and have had no problem with either unit. I can see no way this filter could cause enough drag to burn out a motor as the previous reviewer suspects. That's a puzzle. As for the Ultra Allergen filter, I don't believe it's the final answer for people with serious allergies, but it certainly will reduce allergens in the household environment....more info
  • Best filter on the market
    I replaced my A/C units with Trane 19 EER units almost two years ago. Since new I have used 3M Filtrete Ultra Allergen Filters, and the A/C evaporator coils are clean and shiny like new. Filtrete filter, captures all our dog's hair, house dust does not let it reach the coil. Filter has a strong wire mesh reinforcement that keeps it from buckling and allowing dust around the edges. ...more info
