I have tried everything from spun glass filters to 3M brand 'Filtrete' filters. PROS about spun glass filters: low cost. The Bad: Allows tons of dust mites, bacteria, and dust thick GUM oily Pet dander film to stick to EVERYTHING.'Filtrete' Brand Just the OPPOSITE of El- Cheepo Spun Glass filters! 'Filtrete' not only protects your multi-Thousand Dollar HVAC System,Including ducts to the main cooling coil, Promotes better cleaner air inside your home. Less dusting furniture to LESS spreading airborne diseases and sicknesses. Pet dander and oils are Trapped by 'Filtrete' brand filters and NOT by spun glass filters. I have an air compressor so I can blow out and re-use the 'Filtrete' filter another 30 days before discarding it and buying another new one. Okay, call me Cheep...I just like to stretch my dollar a little further than other people do. 'Filtrete' brand cost about 4 times more than Spun glass filters, but are worth 10 times more from investment protection to BETTER health!

Easy to deal with - great service - website is easy to go through.

Filters are a great value

Love my dog, but don’t care to inhale the fur and dander. Great filter if you have one allergy and don’t want more! You can really Tell the difference!

Larger size came quickly but others took much longer.

Quick and easy. Filters work great

Excellent filters at a remarkable price with fast delivery. It' s what keeps me coming back over and over! What' s not to like?

The filters are easy to use and light weight, but work hard.

Fast delivery, good quality.

I have used fridge and AC filters from " Filters Fast" for over 12 years. The price is right compared to store purchased filters, even those from HD and Lo' s. Fast shipping and good service. Never a problem with the filters. Have used several sizes.

I really like that I didn' t have to keep going to the store, and having to buy one every month, easy to store, and right there when i need it

The filters work well. Need to change every 90 days. A bit pricy. Not a lot of savings compared to similar filters at the big box stores.

I typically purchase my filters in advance and these delivered as promised and are sized to fit.

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.

Quick delivery thank you!

timely delivery packaged well

Product exactly as advertised Very good delivery Excellent Reseller.

I was tired of the grocery store and “big box store” filters collapsing and becoming difficult to remove these seem a lot more robust . So far very satisfied.

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.

Filters Fast has great prices and great customer service.

I need a hard to find size, Filters Fast always has them in stock and ships fast!

My third re-order! Recommend!

I was able to find what I needed very quickly and the checkout process was very smooth. I received my order fast and it was correct. I will definitely use them again.

You can' t do any better than these filters.

Very efficient! Great pricing! and auto-delivery is a must have!

Very good for removing dust from the air!..........Used with construction going on in part of the house.......It kept the rest of the house dust free!

They are fast and reliable. The filters were what I ordered and they got here in record time. Reasonability priced.

Top source for private lable and brand name products. Excellent service.

Great like filter fast saves

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.

We bought our filters a few weeks ago. We finally replaced our old metal one with a new Air Filter and it fit perfectly. We' re very glad that we found this company since 20x20 filters are next to impossible to find.

Quality filter delivered in a timely manner!

I got a dozen of these for a great price and fast shipping. Very happy.

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 filters works great catching pet dander and fur

These filters work for the same contaminants as the ones at the big box stores for half the price.

Shipping was excellent. Filters were perfect.

Ordering from Filters Fast is so easy and quick

They arrived quickly and now I don' t have to go to the store and find filters for my furnace I am set for the year.

Ordered, shipped , and received with no problem. What else do you need to know? Oh yeah great prices and great products!

Customer service has improved, autoship is great, but at times it is difficult to change order.

With Filters Fast the price is less than at the store for a comparable filter and I don' t have to remember to go out and purchase more. I get the filters before I run out.

Always ships very quickly and is packed so that no filters get crushed in shipping.

I ordered to wrong size , was refunded the money & I donated those to Habitat for Humanity , they sent me the correct size no problem

Easy to order, saves time and money, what' s not to like?

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'm sold. 'Nuf said.

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.

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.

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.
