  I really like the job they do I change my filter once a month to make sure all is well. Getting them delivered directly to the house is a great benefit, since I purchase 12 at a time. I highly recommend these filters, customer service is great I also get my refrigerator filters from them.

  Very good filter for average household
  ballyglas  Wednesday, July 18, 2018
  
  Unfortunately my house is not average! I have two large dogs that are in and out frequently. My house gets dirty quickly and their hair and dirt get sucked right into the filter. The filter does a great job but I have to change them every 3-4 weeks. My pocketbook needs a cheaper solution.

  A/C Filters
  rziggs  Wednesday, July 18, 2018
  
  Filters arrived on time, undamaged. In my opinion, A/C filters from name-brand companies are highly over-priced. I have been using the Filters Fast in all 3 of our home return ducts for 90-days, no complaints, no noticable difference in filtration air quality. Wish they carried sizes to fit our Motorhome!

  Great Air Filters
  norayforrest  Wednesday, July 18, 2018
  
  I like the convenience of buying my air filters from Filters Fast, not only do I buy my furnace filters from Filters Fast I buy my refrigerator water filters from them. They have reasonable prices compared to big box stores, plus my filters are delivered to my door. No need to go to the big box stores only to find they are out of my size furnace air filter or my refrigerator filter, I know I can find exactly what I need at Filters Fast.

  OK filters, Terrible company.
  ronrogersphoto  Saturday, June 30, 2018
  
  Filters are OK quality but flimsy, not as well made a product as 3M. Big problem is how the company operates and treats customers. Be extremely careful at ordering, they attempt to put your account on auto reorder which automatically charges your credit card after what they think is a proper filter change interval. Had a huge argument with them after receiving a duplicate order after 6 months. I had initially purchased sufficient quantity of filters to last me 2 years. They refused to issue a RMA sticker so I could return them and told me it would cost me another $30 to do so. I protested to my new credit card company and won. Not an honest company to do business with. Recommend pass on this one.

  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!

  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?

  Bearded Teacher - NJ  
  
  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.

  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.

  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.

  Scott W. - Hickory NC  
  
  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.
