Filterbuy 16.5x21.5x1 Carrier Compatible Air Filter

We are using Filterbuy custom filters for everything in and around our house. We love them!

No complaints

👍🏾

Very satisfied with the product

Can you please look into seeing where my order is?

Evidently my order was lost. I called two weeks after my credit card was charged as filters had not shipped. Was given the option to just cancel the order. I explained to the nice young man that I would not have ordered them if I didn’t want them. Three days later I got the email saying my order was shipped. No reason given for the delay. Filters fit perfectly. Hopefully my reoccurring order will go smoothly.

I had trouble getting replacement filters that fit. Filterbuy has every filter seemingly though.

Never came to my home

Great for the price

i bought a different size all is well

Filters were made a 1/16" inch larger than the ones I bought from FilterBuy previously making them a very tight fit. I'm shaving off cardboard to put them in. Also, although it may not be their fault but a FedEx issue, it took 2 weeks to get them delivered. Not awesome.

still haven't received order

I’m not the type to be aware of times to change my filters but Filterbuy makes it easy to remember and get an unusual filter size.

Fit perfect. Took a while to get here but will definitely order again.

Filters fit great , fast shipping will do it agian

Great purchase

Excellent product and prompt service.

Exactly what I ordered

Perfect!!

Came quickly

I have an odd shaped heat exchanger and It is great that filterbuy can do specific sizes with many customization options. It is all online and you dont need to call them or send emails etc. However I still believe there is a room for price improvement. (Cut one star due to price)

Excellent product and quick shipping. Definitely will continue to buy from this company.

The filter is a good fit with the custom size I had to order. The filter holds up as well as other more expensive brands.

Ordered one month ago and still hasn't shipped

Wrong size….you shipped the right size.#5

The fit was perfect, so that as a plus, and much easier to put in. The quality was a huge step up from the ones the installer left for us to use. I think it’s too early to decide on the dust collection, but I think it will be better. I’m happy with my purchase. Thank you, Terry

Quick! Easy! No fuss…no muss!

Confident in quality!

As always, excellent products excellent selections, excellent service.

Excellent service quick response filters within three or four days

I've been using FilterBuy for my home filters for a number of years. I recently needed to get filters for a variety of units at my church and found some needed extremely unusual sizes (where can you get a 38"x23"filter?). FilterBuy delivered quickly at a reasonable price and they are the exact same material and construction quality as the standard sizes.

Fit was nearly perfect. Let's see if it lasts for 180 days.

The filters arrived on or about the time as promised. I found your website very user friendly, and the filters appear great. I will be using your product in the future. Thank you. D. Ward

Fast and easy service.

Great service , great quality filter. Sized exactly

Quick shipping for my first order, a quality filter and very helpful customer service!

Great filters

Got what I ordered

Great product and amazing service!

Good filters.

I had given up hope to find a filter the correct size to fit my odd sized furnace. WOW!!! I am so impressed. I custom ordered the filters and they fit perfectly! So happy! Quick delivery and excellent service!,,

The moments I saw them I said this are the ones perfect feat. Where this guys been all my life. Thanks.🥰😁

i will review these once I get them!!!!

I have used filterbuy for years. Recently moved to Florida and again had very odd size filter. Within a day, you could tell the difference in the air quality. Would recommend Filterbuy to all I know.

This is my second time ordering from Filterbuy. Great customer service. I love that they can customize filter to the size that I need. Great quality. Perfect fit. Thank you so much.

I just started using the 11MERV. I hope will work better than the 8 I used to use

So happy I found a company that could make my odd sized filter at a reasonable price. Ordering was very easy and delivered in a timely manner. Would definitely recommend.

Fit perfect!

Ordering and delivery went smoothly. I still have not been able to install the filter. I am older and have to wait to have someone install it for me.

Great website and quick delivery

Terrible. U sent me the wrong size

Quick delivery, competitive prices and good quality filters!!!

Perfect fit - odd size filter

The last women I spoke with was both helpful and knowledgeable. I hope all the issues were corrected and I will receive the filter. Thank you.

I have always shopper with Filterbuy for years! Custom made and a quality product ! Shipping is FAST as well! THANKS! Dave T.

only recd the 6 standard 16x20 filters. never got the 6 custom size

Great custom filters!

Took 3 shipments to get the correct product

There is less dust and we breathe better

Pleased with the filters

Exactly what I wanted

We received the custom filters very quickly, as promised. They were excellent quality and they fit perfectly. We will definitely be ordering again from them.

Excellent customer service!

Great turnaround time no problems

Fit perfectly.

the order was delivered timely and without issue

Have been using this brand filter for a year and are very happy with the filtering job they do.

I should have received the filters that I ordered in April , hear it is May 7 , I still have not received the filters . Very poor service .

17 days to deliver, and box was crushed when it arrived via FedEx.

I ordered custom sized filters. The filters I received are cut down from standard sizes. However, the filter material was not cut down but scrunched up inside. Besides not a great look it creates an unprofessional produced product.

Quick delivery, great quality and price!

First Package all filters were crushed in shipment, not sure they can be used.. poorly packages loosely so the banged around in the box

Filter came fast...well protected in a good box..

Always fast delivery and great products.

Fits perfect and definitely does the job. Keeps out dust and cat hair

Fast shipping Filter Buy is always on point with the quality of their products

My factory original filter for my Carrier system disintegrated and my tech was always advising me that this filter was an unusual size and not available in most stores. He was surprised when he came to do my spring service and found a quality filter that fit my system perfectly. He mentioned that it would also keep debris from collecting on the condenser coil, which is good. Thank you.

Perfect fit, good quality

they're great

Prompt delivery of a custom fitted filter.

Great quality

Purchase worked out fine.

Convenient, easy and found the right size filters that no store carries!

Great filters at a reasonable price

It’s been almost a month so far and I still haven’t received the filters I ordered.

They were delivered on time and the correct size.

Great quality and is a perfect fit for hard to find filter size. I will continue to buy from Filterbuy for my filters.

Ordered 3 MERV 13, got 3 MERV 11. Called them they said to keep the wron ones and they would send out the correct ones. Got the new ones quickly but they were also MERV 11. Called them again. They wanted me to take pictures of what i got and email them to them. I did that. I think they want to send me out more filters!! I told them not to . I have 6 wrong MERV 11 so i will just use them. I do believe they shoukd do something tomake this right though. Also told them to check their order pickers/ fillers . They need to know they have a problem. Filters are an odd size and hard to find . These fit perfectly and seem to be very good quality. So if you dont mind the aggravation of gettind a wrong order teice and having to call, i would buy them.

I custom ordered a dozen 10 by 10 and 14 but 14 and 18 by eighteen. I needed the true sizes not standard which run about 1/4 to 1/2 smaller than the true size. I called them and will say they were really good about it and replaced them at ni charge. The problem is they sent the same smaller filters on the second order.

So easy to order, website is excellent! I have order a few times and it’s great, fast delivery!

Fit perfect. Good quality. Would buy then again.

Great delivery

As expected good quality

Sized exactly as requested. Well made. Arrived before the promised date.

These filters are exactly the quality, design, and size needed. I will continue to purchase from Filterbuy!

They came in a very timely manner, they fit perfectly and time will tell how well they work.

Your shipping policy is simply the worst in the industry.

Everything was very professional. From the person I was ordering from. To the delivery. I’d recommend this company highly.

Customer service was very helpful and efficient.

Fine. Fit was correct.

I had to get a custom size to fit my location. The filter helps with air flow being cleaner.

Fast delivery, fits perfectly. I struggled to find this size and am so glad you carry this off size.

👍

Great filter, easy buy from website.

Very happy

Received filters very quickly. It seems to be working quite well now and I expect it to continue to give us good air. Really happy that you could deliver the proper sized filter as I was having a problem finding one until I found your website. Thanks. Jerry

Very good filter but it was a tight fit.

They arrived on a timely manner and were the size I ordered,but were a little pricey

so far the wine is tasting very good,

I enjoy that I get filters that fit my furnace which is an odd size without any problems thank you

Fit properly, well constructed

Very happy that the size is right and they fit with no problem.

ordering was simple and easy. always good.

They have the exact size and filtration screen that I need.

I received my order in 3 days! Very happy with this purchase!

The filters fit well and are attractive. They are also easy to install. I was unable in the past to find a filter that fit at my local hardware store.

Excellent product. Perfect fit.

Thanks

It's great to know that your Reps are there for you, every questions I ask they answer effectively, with a solution, thanks for your assistance and support, made my transactions easy and worry free.

Very pleased

First off, I want to say how excited I am that this product came from within Alabama. The order was placed, shipped and received quickly. The filters we purchased fit perfectly. I have major asthma, allergies and Lupus so the purchase was because of what the filter offered. The filter we use with our Bryant Dual system. I have recommended this company to other family members and friends. We will be ordering from you from now on. Thank you !

Available, quick delivery and it fits!

Finally found someone to make the right size at a reasonable price and deliver them in a timely manner.

Why has it taken me this long to do this? I have been buying the cut to fit filters for years and disliked all the options out there. Thank you Filterbuy for making the perfect sized filter so I don’t have to do that anymore. No more running to the hardware store. Home delivery rocks!

My first purchase of custom sized ac filters is so far so good. The construction design provides supports on both sides of the filter so suction will not cause it to bend.

It’s great, thank you.

Very good products ,thanks for making them at that side, I was looking for them in any store but I did not find them,now I got them thanks

They look good. Have not used them yet.

Goog

good price good service

filters are great...customer service is great. only issue is telling me that delivery date will be delayed BASED ON WHAT I ORDERED after i committed to the purchase. Need to be more transparent around delivery times

Filterbuy provides odd sizes, and quality high grade filters at a discount when purchasing in multiples. Customer service was great. Delivery faster than expected.

Works well

Good

Could not find in stores. Thank you.

Perfect fit, good quality, and arrived quickly.

Nice looking filters and the right size

I notice that the air is lighter already. Thank You Filter buy.

Great filters!

Easy to find what I needed on your website. Just an overall pleasant experience.

Good quality. Fit good. Price could be lower

Perfect fit easy to install.

They looked nicer than the ones I removed. Fit perfectly

Fit is prefect for my odd size filter, quick ship and good quality.

Excellent Service!!

Quality product Prompt service

The filters fit real good and filter the air even better, is helping with my asthma, will buy again. Thanks\

Very satisfied with the quality. The size was perfect.

I have a new HVAC system and couldn’t find the filters it needed at my local hardware or Home Depot store, it is a very odd size. This was my first time ordering filters online and I was skeptical, however, the order process was easy, their website is user-friendly, the filters came quickly, packaged safely so they were not damaged and the product was intact and as described. I will definitely order from FilterBuy again!

My Experience with FilterBuy was Great. My Order got lost in Md. And I contacted Customer Service and they Got back to me Quickly and Got me Back on track and Were very kind and helpful.

great filters for the price

Filters came quick, good quality. I'll continue using them.

Filters are perfect. Fast shipping too!

These filters arrived in a timely manner and fit my carrier HVAC system perfectly. I will be buying from here again.

Fit perfectly, quality so far so good, package good.

The filters are everthing I expected.

Greay

Good service

fit good. worked great.

First time buyer. I'll be back. Good price, fast ship, perfect fit!

Great service !!!

Great quality product at a very good price. Size was perfect. Excellent customer service!

Filter Buy is the only place we'll purchase our filter's from now on! We could never find our filter size in stores. We had to cut them ourselves to fit. The price was less than the stores and we found the filters to be of better quality.

Great fit, fast shipping. Happy with the buying experience overall.

Very happy with the MERV 13 filter. Noticed less dust in the house since we started using these filters.

Well made filter that arrived quickly and in good condition.

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!!
