Carrier 16.5x21.5x1 Replacement Air Filter Replacements

I hope they fit and work as well as advertised. I bought ahead of time so I'd have them when it's time to change out the old ones. I've been using a washable, reusable filter with great success for twenty years.

Fit and filtration .

Excellent customer service.

Great filters. Received them fast., within a week of ordering.

Great job.

Awesome service at a great price. Filters are a lot better then the ones sold at Lowes.

Our ac system needed a non-standard size filter for the 2nd floor. I figured this was going to cost a fortune. Instead I got a custom-sized filter delivered for only a few dollars more than a standard size filter cost at the local warehouse store. Very happy I found this place!

I've been purchasing HVAC filters from Filter Buy for a few years. The website is easy to maneuver and the prices are fantastic! Recently I opted for the Auto Ship option and I will am confident that Filter Buy will deliver on time... also I saved a little more by taking advantage of the Auto Ship! I definitely recommend Filter Buy!

It fit perfectly except for the 1" width. With some prodding, we made it fit however.

I had tried to find the exact fit for my Heat Pump but wasn't having any luck. I tried an almost the right size, and that didn't work well at all. You had the exact size and it was easy to install. I will order more when I need them again.

Excellent service / perfect fit/ great quality / fast delivery

The filters were delivered very quickly and they fit perfectly.

Excellent filter

Filters are great. And customer service is wonderful. I did have a problem but it was resolved rather quickly. Thanks

Very satisfied.

Thanks

The price is great, quality is great and customer service is great! FILTERBUY!!!

I have been buying these filters for the past 3 years. I modified the filter housing to accept these filters and they work great. I like the fact they can be made to the size needed.

Quick shipping and perfect fitting.

Filters arrived boxed. Size and level as requested. My unit requires an odd size hard to find in stores and online. Just put one of the filters in, seems to be working ok.

Custom size fit perfectly. Reasonable prices. Excellent quality. Timely delivery. Used filterbuy for 4 years and always had good experience.

Service is outstanding. The filters are of the highest quality. Thank you. Will continue to buy my filters from you. So happy I found you!

Good price for filters that are just as advertised. And very good and prompt customer service.

Fits perfect.

Fits perfectly couldn't find them anywhere

Fair price, high quality product with a fast delivery.

Ordered from Filterbuy for the first time. The young lady was very helpful, the price was very fair and it came in about 3 days. The filters fit perfectly since they were a custom size. Great Product! Would highly recommend this Company and Their filters. Shari H

I have not used the filter yet, but it measures as described and delivery was prompt.

As I have stated previously in reviews, I am so grateful to FilterBuy because the filter for my furnace is a very odd size, and is not found in any local stores. If not for them, I would be in dire straits.

Filters

Thank you, our unit has a filter not a common in our local stores.

great as usual

fit to perfection

My furnace either used a custom sized filter from 35 years ago that is no longer produced or the furnace intake was installed wrong. I had to order a custom size and it worked just as well as an off the shelf filter. Delivery was fast and I will be using filterbuy probably for the rest of my furnaces life. Glad I found this site! Highly recommend their custom sizes and service.

Easy to order, good time frame for shipping, well packaged and a high quality correctly manufactured filter, thank you!

The measurements I sent produced a perfect wall air intake filter...

Product was as advertised and is the only place I’ve been able to find these filters.

I just had a new heat pump installed recently, and the installer wrote on the heat pump that the size filters I need would be 18x20x1. A common size that can be found just about anywhere, however, that's not the size it takes! I went everywhere trying to find the right size filters. Nobody had any that would fit. Then I found out from contacted the ICP customer service, that you can only buy the filters from the installer. Well, I knew that wasn't going to happen because I had a bad experience with that installer. He told me he was installing a Carrier, and when I checked the serial and model numbers, I found out it's not a Carrier! Then he said it's a Tempstar. Not that either! I googled my serial and model numbers and found out it's Airquest!! The installer was Absolute Comfort and Son in Red Lion,Pa. Just out to line his pockets!! Anyway I did some searching and found you Filterbuy, I could not be happier!! My filters arrived the other day and they are great!! So happy that you have my odd size. I will always be a customer! :))

So far as I know, I guess I won’t know until I take it out and see how well it did.

The filters fit as expected.. was happy with the delivery time

SO happy that we can get replacement filters THAT FIT and are affordable.

Product was described accurately and the shipping was fast!

Got the product I needed in a short period of time

Excellent product and service!

Quick delivery, none of the delays and evasions by another (formerly??) leading filter retailer. I will stick with Filterbuy.

Great.

None of the Big Box stores carried the size I needed. Filter Buy had the exact size in a great filter. It shipped faster than they said it would. I could not be more pleased.

Everything arrived in perfect order.

Great service

Easy experience

I was pleased with the customer service I received. They were very attentive and resolved my issue without any problems.

Best customer service ever. I had very odd sized filters and they quickly shipped out what I needed. Perfect!

Your filters fit perfectly! They were shipped quickly. I will be using your service from now on.

Fast ship, easy to order

I enjoy your product and hope that these new filters will be better and help in keeping more dust and pollen out of our house. Thank you

Perfect... thanks

I got the exact size filter for my A/c. Yet, this brand is longer than other brands the same size.. I still made it fit...lol. So far so good.

Na

Had the exact filter I needed. Free shipping. Great price.

Great Quality Filter

I wouldn’t buy my ac filters anyplace else, excellent quality.

Be excellent to each w

Happy to find filters for an odd sized a/c handler that fit correctly at a reasonable price.

Was exactly what I was looking for. Fits Carrier a/c perfect, was a little worried, because installers of unit put in 16.5 x 21. Extra half inch fit exact. Clean air. Right MERV rating for me. Got here fast.

👍all good .. very fast delivery! Thank you!

So glad I could order reliable custom fit filters for my new house. I'll be re-ordering in the future. Thanks!

Hard-to-find filter size, reasonably priced, very quick delivery. Am pleased.

Good

Great filters that fit my Bryant AC and fast shipping

product, pricing and delivery all good

They shipped fast and the order was correct.

Filter Buy has been a great help with reminding us about filter changes; and they deliver top quality filters right to the door!

Great selection and fit

We could not find this size locally. They work perfectly.

Fits great

Great service

Nice job!

Looked on-line; found a good price; ordered the custom size filters; received the filters quickly; filters were what I ordered and looked fine. No nonsense process. I will order more when I run out.

Easy to order fast delivery and will be informed when I need to order again

Excellent price and service!

very good and easy. looking forward for referigator filters some day

A great substitute for the OEM Carrier/Bryant horsehair filter.

I recently received the filters I ordered from FilterBuy. They came in exactly the size and type I ordered. I have not installed them yet. I have no idea how well they will actually work in my furnace/AC unit. I am a bit annoyed by their frequent requests to submit a review. The first such request came within a day of my order, about a week before the filters showed up. I think a bit more patience would be in order.

great price

Great product

Was a little messed up. Smooshed whenarrived. The box wasn't so it was shipped that way. All in all its ok.

Buying filters are so easy and simple. Plus they keep your info from the last time so you don’t have to go searching for with size you need.

Quick, very affordable, and great service....an excellent value.

I received the incorrect product, but CS was able to resolve very quickly.

Help

I received the filters just two days later I had to replace my unit however the tech left the old base on so I could use them. Thank goodness so please do not send me an automatic renewal set since the size has changed.

Inexpensive, easy to order, received quickly and in perfect condition.

The only thing I would like to see is a rating printed on the filter just to make sure it is the highest rating I paid for. The filter works well and was delivered promptly. Thank you!

waiting for delivery. ou sent wrong size. I understand I will have them in a fe days.

Received specialty filter size exactly as ordered

Without your company, I would be hard-pressed to find the correct size filter, so you can never go out of business! The filters fit perfectly into my oddly shaped furnace.

Very hard to find, great price. Looks of good quality,installed today.

Filter was the right size and delivered as promised.

very happy with the purchase experience. Excellent and helpful sales person i contacted via your 800line, because i had no idea why one grade of filter is better/worse than others. suggest you track the effectiveness of your advertising by asking people where the heard of you,For my part, never heard of you till I heard your ads on Limbaugh/Hannity/Levin. Arrived promptly. will recommend to others!

We just replaced our filter; it was difficult to find correct size. Filterbuy shipped it promptly and fits perfectly

Great information to get unusual size filters.

No more trying to find my odd size filter at the local big-box store. This is perfect. Box of 4 lasts 1 year! Good price! Very easy!

Great!!

Good outfit to purchase filters from

Perfect fit and well made compared to other filters i have purchased recently will definitely continue with your company.

Great as always! So convenient as a landlord

Very good

Fast delivery

It was very easy to order, lots of choices for different needs from basic to more asvanced filter. Great customer service

Excellent website. Easy ordering. Quick delivery. Very good experience!!

Perfect fit! Fast delivery! Will buy again!

Very good!!

Very good. Thanks

Got this filter from here because everyone around me stopped selling custom sizes. The filter arrived very quickly and once installed my fiancé who has really bad allergies noticed he was breathing better within a few days. Definitely will be ordering another in a few months.

Better value

Very smooth ordering and receiving process.

It came on time and It fitted perfectly in my carrier furnace and very sturdy! , plus I found it very convenient to sign up for automatic delivery every 3 month.

Good product

Best service. Thank you

Filter fits. Only in for 3 weeks. We’ll see

The filters are fine. Everything fit perfectly. Will order more in the future.

Delivered fast and true to size.

Filters (custom size) were fairly priced and arrived in a timely manner.

great customer service, easy to order, and the auto order ensures I have filters when I need them without taking a trip to the store, to find out they don't have them in stock anyway.

It unfortunately took me a couple of times to get the right size filter, mostly my mistake of measuring but the customer service, namely, Angel, was amazing at helping me figure out which size filter to get and taking care of sending me the correct size. In a world of automated costumer service, I greatly appreciated their in person assistance. Thank you Angel.

Excellent Fit, Fast Shipping and Great product

We have a Carrier/Bryant AC that takes odd shaped filters. The filters we received from Filter Buy fit, worked, and arrived in great shape after shipment. A+ folks!

Excellent, great service and prompt delivery,

good

PERFECT!!!!!

Good buy. Fits snugly. Probably should order a little smaller filter next time.

they had all the sizes and shipped directly to me, received in 3 days

Very satisfied with purchase - filter size is odd, so often difficult to find. Very pleased.

Needed a custom size. Fit the air handler perfectly. Very good quality. Delivered in 4 days.

EXCELLENT QUALITY

Filter were exsct sizes thsnk you will buy again soon and delivery was on time.

Have been very pleased with my purchase

fast delivery

Received filters with my exact measurments. Fast delivery. Customer service was courteous and helpful. Have only had the filters in use for about 2 weeks... all seems fine. Product seems to be good quality. Will order again soon.

Excellent

Best air filters I've ever used. Will buy again

Awesome customer service. No hassle and I was able to get filters for my custom size.

As soon as the filter goes in, the airflow in the house improves dramatically. Like a summer breeze running through the house. The reminders to replace filters are awesome. Thanks!

Great delivery, product was correct

You have the wrong size in your request for review. They are 13.5 x 24.5. The filters are fine and the ordering process is easy. I am bummed that the retirement facility where we live uses an unusual size not available in stores. The original filters were marked 14x25, with the actual size in fine print. I missed that, and bought 14x25 filters that I had to throw away because they didn't fit. Thus I need to pay more for my filters online.

Great selection and the best prices!

Very satisfief

If it weren't for your company, I'm not sure where I would find filters for my furnace, as they are such an odd size. Shipping was speedy as always, I'm very pleased.

I ordered 15.25x21.25x1,and it fits fine. For some reason your survey says I ordered 18.25x21.25x1

Filter fit perfectly. Great customer service.

On box was different size.but it works.thank you.

Just the right size that I couldn't get at regular home stores

everything was perfect……..

Great filters, will buy again from Filterbuy. I had an odd shape filter and they made them perfect!

Great service

I ordered custom size filters and have received them in less then 2 weeks which is pretty quick for custom made filters. Price was good, and shipping was free on order for more then $75. Overall, I'm very satisfied with the quality of the service.

I got what I ordered. I haven't used them yet.

Perfect fit ! Fast shipping!! Good Deal !!!

Great experience. A friend told me about your website and my purchase went very smoothly.

Five star

Great filters that I can't find in a store in the right size. Prompt shipping also. They also employ disabled Americans. I will buy from them again!

Fast delivery, hard to find filters. Always comes through.

Only have had the filters for a few weeks but they appear to be OK. They fit in the air carrier better than the filter provided by the air conditioning installer!!!!!
