The FiltersFast FFM1361 home air filter reduces the following airborne contaminants:

  • Pollen
  • Dust
  • Pet dander
  • Mold spores
  • Dust mites
  • Allergens

Healthier Indoor Air Quality

The 1" Air Filters Merv 13 - Case of 6 Filters (Best) is a set of MERV 13 filters effectively reduce pollen, dust, pet dander, mold spores, dust mites and other allergens from indoor air. Removing these airborne particles alleviates allergies and sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing.

Green Technology

This six pack of MERV 13 air filters meets the Green Building Council's latest LEED (Leadership in Energy and Environmental Design) Indoor Air Quality Requirements for occupant health. This 1 inch air filter is a quick and efficient way to achieve points toward your company's LEED Certification, which can earn you tax breaks and save you money!


MERV, or Minimum Efficiency Reporting Value, indicates when a filter will be least efficient. So, a higher MERV rating results in a more efficient filter. Most fiberglass spun filters, such as those found in your local grocery store, are usually only a MERV 1 or MERV 2. This can affect the efficiency and air flow of your heating and cooling system, which causes it to work harder to produce the same air flow and ends up costing you more money! This HVAC filter features a low pressure drop that lessens your energy use, which will save you money!

Quality Construction and Capacity

This allergy air filter is constructed with a galvanized, corrosion resistant metal support grid and 100% electrostatically charged synthetic grade density media. The filter media is resistant to a wide range of chemicals and will not absorb moisture, which can support microbial growth.

This Filters Fast filter features pleats designed to promote maximum surface area and dust holding capacity and are bonded to the frame to prevent dust bypass for higher efficiency and air quality. These filters have 18 pleats per lineal foot for greater surface area to catch airborne particles than standard 1 inch filter and less filter changes.

The Filters Fast M13 1" Air Filter is Available in the following sizes:

  • 5 Star Rating  amazing difference
    Art - Montana  

    I switched to M13's from whatever my local big-box was selling for slightly more per filter. We have been getting 'light' smoke from forest fires. You can smell the difference in the house, and you can see the increase in the quantity of dirt on the filter. A real upgrade!

    Excellent delivery time, high quality. Been using the MERV 11 for two years and now using the MERV 13. Very good price. Wish they had 24x36

    I've been getting these filters From FiltersFast for a long time. I just got a new heating unit and had to order new filters. After I put the order through, I noticed that ordering another pack would get me free shipping. So, customer service to the rescue. They took care of the whole thing in one quick phone call. The filters are fantastic and delivery is prompt. Clean air for less what more can I ask?

    Excellent product, and cheaper than any comparable filter at your local big box store. And, better yet, they come in sizes not otherwise available. As others have noted they do make a noticeable difference in air quality. If you have allergies you will notice the difference immediately.

  • 5 Star Rating  Fine filter quality
    Alan - Texas  

    I installed the filter yesterday and it fits the opening perfectly. I live in a new apartment complex and the filters they provide are just a bit too large for the opening. There has been a problem with indoor air pollution here but I expect these filters will help substantially. There was a slight issue with the shipping I requested (2 day versus standard) and I contacted customer support on this. There may have been a problem with the site or my internet access because both options were listed at the same price. I received the filters on time, though I was expecting 2 day delivery. So far, so good.

  • 5 Star Rating  air so good
    Jiles - Swindalinavia  

    I purchase these filter for my daughter of USA. She says thank you papa for make air so clear. Her man say that this clean is good, because his smoke of pipe is not good for baby. Overall, a good price, and makes me happy of myself for find this great deal using world wide web. A+++

    Excellent quality Filter, even better than comparable filters that I've paid nearly twice as much for. Keeps my air and furnace CLEAN. Great, fast service and shipping too, and your best choice for all your filter needs.

    Great quality filter at a great price. You will notice the difference in your homes air quality. Much less dust, cooking odors go away faster - your indoor air just seems better with this filter. My wife's allergies seem much better with this installed. She noticed when I forgot to put the filter back in after cleaning my furnace.

    Just wanted to let everyone know how well these filters perform. I got mine at the end of Aug 2010 and put one in on Sept 1st. In 15 minutes everyone in the family could tell the air was cleaner in just the ease of breathing we all had. A neighbor came over later that night and could tell the house smelled (cleaner) and he could breath easier. I showed him the filters and he asked to try one for himself (He has cancer and needs to keep a clean enviroment). After on 1 week he orded a years supply and replaced the one he borrowed. He said he slept better and felt better since installing this filter. My home stays cleaner with way less dust. I urge everyone to buy these filters.
