I do not sneeze or have congestion since changing over to colorfil filters.
These are great filters! Never have to worry about forgetting to change the filter.
I purchased 2 filters and so far so good. The air seems much cleaner. I will be using them from now on.
I like these filters. They seem to bring a freshness to the air that my other filters did not. We lack much in the way of outside exhaust of cooking smells and we have a dog, so these filters are helpful.
The filter removed the smell of paint from my new condo in just a few days! I don't have any pets, but it seems like it would work well for that animal smell that pet owners have in their homes. Its also really nice that you can see when its working
these really work. we have 2 dogs & a cat & live in central florida where the a/c is always running. i was impressed there is a noticeable improvement in the air, it smells cleaner.
I have been using this product for over a year and will never go back to a regular filter. It helps to keep my house smelling fresh even with pets and daily cooking. Thank you!
These colorfill filters are great. I put my 1st one in before i made fish for dinner and wow it took care of those fishy odors really quick. I also like that when they turn yellow, its time to change it.
You can see the difference in a new one and one that need to be changed.
Interesting how one filter turned yellow already downstairs but upstairs that filter is still pink. Wondering if the air quality can be that different between floors.
Great A/C filters. Much more sturdy than the previous filters I used. Should probably be a discount for being on the subscription service, but whatever.
After trying so many things to improve air quality, I was skeptical. Within a few hours of installation, there was a noticeable difference. The house smelled fresher and mustiness was gone. The only problem was the filter was indicating it needed to be replaced after two weeks of use. As a retired teacher, I can't afford two of your filters each month. Other than the longevity, it's a good product.
It really works!! Thank you.
Air quality is very important to me and I love the ease that these provide with the color change alerting me when a filter change should happen vs guessing!! The size was not a perfect fit, however customer service solved that issue very quickly. Impressed with the product and service:)
Unbelievable how it has freshened my home! I only purchased one to try it out. Will be buying more. It's a terrific breakthrough in filters!
What amazing customer service. We installed the other filters yesterday and noticed an immediate difference in air quality and dust. Well done. I appreciate the update when the 25 x 25's become available. In the meantime, I'll sign up for the subscription. Well done. Have a wonderful day! Kind regards, Paul
The filter changed to yellow in about 2 weeks. These filters are way too expensive to use seeing they don’t even last a month. They are probably good filters but since there is no actual way to prove they are doing as claimed in my home, they are not worth the extra money for me. Sorry
I didn't do enough homework before I made the purchase of this filter. I did notice that perhaps cooking odors weren't lingering with this filter. But my allergy symptoms increased, wgich I attributed to time if year. However, when my daughter visited a few times last week, she was becoming overcome with stuffy nose, and her ears were even itchy. Since she just moved out, I knew the answer had to be a new variable. After a bit of research, I learned that my previous 3M filter was a MERV 11, while the Colorfil is only a 7 rating. For half the price, I'm filtering out allergens and many other substances that this product left in our indoor atmosphere.
This filter is AMAZING. I hate to put myself out there as a dirtball, but our musty house smell was speaking for itself. We still don't know what the culprit was- we've got cats, an older house, previous water damage, tendency to skip mopping... the list goes on. No matter how much I cleaned, opened all the windows, sprayed, burned candles, prayed to the Old Gods, the smell would come back. Facebook, being all-knowing, showed me an ad for these Colorfil filters and the rest is history. The smell is just GONE. It took about 2 weeks for the entire thing to turn yellow, but the musty smell was gone within the first 24 hours. I've already ordered a 6-pack to continue using, and we just put in the new filter, so I'm curious to see if we get a little longer out of it this time. Honestly I don't even care; I'm so happy to have a fresh-smelling house again! These are legit and I will never go back to the old filters!
The time to change color changed after 4 days I'm leaving them in for the 30 days.
Living in a motorhome, I usually buy a filter and had to cut to size. Wondering why can’t I find a filter that was my size. I am so pleased with my perfect filter, I told them what size I needed and BAM! Thank you so much. I will be ordering again and again. Also watching my filter change colors was cool too!
These are great filters! I notice a big reduction in dust on my furniture and the house smells much fresher without the need for air fresheners or candles. Highly recommended!
Great quality filter and color change technology makes maintenance convenient.
Noticeable difference in the dust levels in the house! With two long-haired cats, this is key!
It is clearing the air.
I haven’t installed them yet, but they look well made and I’m sure they’ll be great!
It is the best filter I've ever had. My older furnace there's a lot of dust. With your filter it helps a lot with the dust and odore
Did (and continues to do) a great job on odors. We had an old house and the musty smell went away. We moved into a new house and it made an improvement right away. I love the peace of mind when I go check the filter and the color tells me it’s not yet time to change. Before these filters I was having to guess if it was still doing it’s job with another brand. I’m actually saving money because I am not having to change the filters as often.
I love this filter you can really tell the difference in the air
Volunteering in animal rescue, you tend to "take work home." This product is a wonderful investment for me with multiple pets or for anyone who knows the importance of keeping inside air clean.
Hands down best customer service!!! I received a damaged filter and they shipped a new one the same day!
I have purchased this twice now, uts Amazing to watch the filter turn from pink to yellow! My home smells cleaner too. I am sold on these!
Love the filter but the shipping box needs to be better. My last filter showed up in such bad shape I did not know if I was going to be able to use it.
They really work it has help I noticed less dust around the house
Only lasted about 26 days so a little more pricy than the ones at the store that last just as long if not longer
Ordered these filters and did not expect much at all. So far the filters are working well and they are still pink!
It’s only been in not quite a month and already turning yellow. I thought they last longer then this with the cost of them . I ordered 2 different sizes .
We have been dealing with cigarette smoke coming from another condo. Trying every type of filter at the big box stores, nothing worked. The Colorfil did the trick!
These great filters arrived fast! Great sturdy borders, made well, I ordered a custom size 30x10", & still arrived shortly, all 4 fit great & I know the allergens & odor will be filtered out so we can all breathe so much healthier, thanks for a great product, will highly recommend to others, thanks, Vicki Allen in Beech Island,SC.
Just put a new one in as the old one was a generic one.Will let you know in a month.
Recently received my second re-order of these filters. I order under the custom size category they fit perfectly and they do exactly what they are supposed to do. The Merv rating is perfect for my all electric residence.
Cleaner air hopefully less indoor pollutants.
It lasted 17 days. I was thinking it would be longer.
Bought these in the hopes that it would help with air quality at my mother's house (she is 98 and the better the air, better the breathing). So far, have now seen the effects of putting the filter in (just been in about one week). However, anything that will provide improvement, is a good thing.
The filter only lasted 5 days. I didn't notice it the Air quality change. Not worth money I wish it would last a month.
It really works!! The air in my home has a fresh smell but best of all my headaches have been reduced to almost none —before I had 3-4 a week—I’m so glad I stumbled onto your ad —Thank you for providing such a quality product and one that truly works like they say it will.
I am a professional petsitter that may have up to 6 dogs at one time in my home. I noticed that my house had a doggy smell even though all dogs are clean and well taken care of. I had tried plug ins and sprays but then my chihuahua had a seizure and I read that sprays could be toxic to pets. I searched the internet and read about these filters. I decided to give them a try and so far we are loving the fresh smell in our home. It's only been a couple of weeks but we are very pleased. I would recommend this product.
I usually change the filter every 2 weeks since I have dogs and a bird. This has been in 3 weeks and while still pink it looks like it is changing just a little bit. I am hoping as time goes on it will take longer and longer in between changing filters.
The Shipping was very Quick and the Package was in Great shape. No damage to the Package ..I will be getting more.
So far so good! My home smells better, fresher.
So far so good! Very good a filtering smells from cooking and such. Very little dust!! I’m happy so far!
Great product! It works as advertised! I ordered one filter for a trial purpose and was pleased by the results, so I ordered a six-pack. What I really notice that there was less dust over time in the house. The changing of the filter from pink to yellow was an added benefit when it came time to replace the filter with a new one.
Fast delivery, just right
I notice a change in the air in my house as soon as I install the new filters. Great product!
We really like the filters and think they make a difference in the air quality! This is one of the best companies I have ever had the pleasure of dealing with. We are repeat customers for a reason!
I love using Colorfil in my home. We recently had our ducts cleaned and I instructed the service tech to use my new colorfil filter in the furnace. He had a lot of questions about the product because he had never seen it before. I was happy to share my positive experience with him. I feel so much better using this in my home, with my husband and 2 long hair maine coon cats.
REMOVES SMOKE SMELL!!! We purchased a house where the previous owners smoked for decades — gross! The house was completely gutted — painted with Kilz twice over — nothing would get rid of the smell! We saw the Colorfil filters online and thought to try it out — why not! AND IT WORKED!!! ALL THE SMOKE SMELL IS COMPLETELY GONE!!!!
When you have 2 border collies in the house you need an air filter that really works overtime. And Colorfil does exactly that and I would recommend it to other people.
The filters came thru to small for the opening. The standard filters I get in the store have the same measurements but fit well. The ones I had you make came thru small and don't fit properly, letting air thru the sides and making a lot of noise. While they are much better quality than what I can buy in the store for this older size filter, if they don't fit they have no value. They are likely getting returned next week. For the price, they have to be right, and they are not.
When I was younger I never had problems with congestion or stuffy noses, but now that I’m 44 every year down here in FL seems be get worst then the last. These are hand down the best I’ve used , I spent even more on DuPont air filters in stores and online ordering but these hand down work the best. I also have a 7 month old son which gets stuffy noses and or I have clear the nostrils out but with these he might have one booger in like 2 weeks. So all around it’s a win-win
Love them, only filters I use now
Great product! Great company! Keeps the house free of dust and cat hair. The change in color makes it easier to swap filters since the 3 month guideline for other filters really depends on a case by case basis. Love it!
I love that this really removes odors. It is easier to install since it don't have to watch arrow orientation when installing it. Love the colors and watching it change. Wonderful product wish I had seen this sooner.
Was having my duct system cleaned. Owner of company was impressed with filters and MERV rating. Thanks
It went in pink and it’s now a neon yellow! So, now it’s time to change the filer. This is so great! And we’ll have clean air always.
These filters DO refresh the atmosphere in my home. I’m older, with allergies, and I’m willing to shift budgeted monies to such a health item. My stock stays steady, as the seasons do affect the life of the filter color, but it’s worth the cost.
These are great filters! So easy to install and they come with a color coded magnet that you can write on with the date you last changed your filter! Love them so far!
This was my first time using Colofil filters. I wanted to support a local company and I was frustrated with the HVAC filters I had been using previously. The Colorfil filters have the nice color-changing property so you can tell when they need to be replaced. They also are supposed to help with actually cleaning the air. We are spending a LOT of time home during the pandemic so I was interested in having cleaner and good smelling air. The Colorfil filters lasted a long time and worked well. I have bought them again since my initial purchase.

Love these filters. Been watching and waiting for mine to change colors! Not getting much work done but then again there’s a pandemic and I’m pretty much retired. The filters arrive soon after ordering in a nice box that you can store the extras in. Get ya some!
I have 5 dogs and the dust n pollen they bring in my apt is insane. This aggravates my allergies. Nothing I did would help until I tried Colorfil and wow! I can really feel and breathe in the difference! Not only do I not have allergies anymore, the air in our home is so much cleaner you can smell the difference! No more mold n mildew smell in our bathrooms! Highly recommend. I change mine every 6 months vs yearly due to the amount of pets and humidity!
I live in a 4-unit apartment complex. When my HVAC system comes on (A/C and furnace), it draws cooking, laundry and smoking odors from the other units into my apartment. Drives me nuts, especially the smoking odors!!! I can't sleep at night sometimes because the odors keep me awake. I've tried several different types of filters to try to eliminate (or at least reduce the odors), but none worked. Then I read about Colofil filters. I'll admit I was hesitant at first to get one because of the price, but eventually decided to give it a try and bought two as they were on sale. In the two weeks since installing one, I've noticed a major decrease in the amount of odors that come into my apartment. Yay!! Thank you so very much!!!
Great so far!
I really like these filters! The color change helps me remember when it is time for a new one, and they work great!
I’m on my second order of filters. They do a great job filtering the air and helping keep dander and allergens down. Something I need with three cats and a dog. Definitely worth the money.

I'm trying my first "fancy" air filter from Colorfil. So far so good! I'd never heard of these filters until I bought a mask from Seritonix (which is basically the same company, I believe) that utilizes a piece of the filtering material. Looks like I'm going all in with Colorfil! The filters arrived promptly, it was simple to install (DOH!) and everything is, as my mom used to say, copacetic.
We recently moved into a house that has a totally redone HVAC unit. The filters work so well and helping our house smell clean.
These filters really work! I noticed a difference right away in reduced dust levels and no more pet or musty odors! Highly recommended!!
air seems to be clearer and furnace seems to work better fit is perfect
I’ve been using this company for approximately two years. I like the filters’ performance. My small home is old with a chimney. Cooking, cat, what-nots, it does have a character smell, but these filters do process these smells very well to a subtle whisper—the air is not stale at all. I have no thoughts one bit to changing my customer status with them. Happy.
I really liked that they will custom fit your filter if your size isn't listed!
I saw these advertised on Facebook and I had a look at them. I did a little research and Colorfil had good reviews so I took a chance and I bought them. I have been trying to find a way to get rid of the dog odor in my house...and this product is supposed to get rid of odors After installing it, the odors were gone..It was unbelievable.. I am happy. I would have like to try one before having to buy 6, but glad I bought the 6...this will be the filter I use no and in the future
These filters are the best! The lower level of our home can smell musty when the air is cool and still. These filters help keep those smells away as well as the smell of our cats’ litter boxes. I feel confident the filter is working based on the color of the filter. I am very happy with these filters!
Excellent product and excellent service. Product was shipped promptly and it arrived quickly. Always pleased.
So far, everything about this product is great !!!
First off... these filters work. Tennessee is the capital of country music. It's also one of the nations top allergy capitals. How do I know, I live here. Throw a couple of cats on top of the pollen and you'll be sneezing from March to November. The pollen gets so bad, even the cats start sneezing. And anyone that has pets can tell you it's a full time job to keep your home from smelling like a pet store. After the 1st week with a Colorfil filter installed you could tell a difference. The air actually felt... lighter? After the first month, I noticed we weren't sneezing as much... including the cats. After 4 months there's a big difference in our indoor air. It feels and smells cleaner, fresher. Do we still have to reach for the occasional antihistamine or decongestant, yes. All in all, these a darn good filters, probably the best.
We like the filters and the house does not have lingering odors.

My sweet boy is big and furry. But after using Colorfil my dust level is down and no dog smell at all.
Love knowing my air is cleaner living in a condo building!

This was my second order for these filters. They cost the same as the ones from the big box store, but do a much better job at getting rid of the odors in the house. I was a bit concerned at first because the color change happened so quickly (after 21 days) but then I realized that I am a smoker, and we have two cats, so it was not surprising that it happened. I left the filter in (since it was not dirty enough to change) and changed it after 90 days to a standard filter. I placed my second order for these filter simply because they a much better job at the same price.
These are the most amazing filters I have ever used. Got my first set 6 months ago after trying so many others in the past 25+ years. They are fool proof by changing color when it’s time for a new one . I needed a custom size, no problem, no extra wait, and same price as their stock sizes. The best part is the way my house feels and smells better than ever. No need for scented pads that cost extra money from the department store which are not cost effective needing to be changed every few weeks. With the weather turning cold and switching to heat they are still making my home smell/feel fresher than any other filter on the market. They last the longest and are in my opinion the best you can buy !
I have cats, and very bad allergy's. This filter decreases dust and pet allergens at least 50 more than the leading allergen brand at home depot.. I highly recommend
Your filters have done a good job with odors and pet dander. Three cats and a dog can create problems. I appreciate the fact they change color when they need to be changed. A bit pricey, but worth it.
This is a great filter. I have 6 rescue dogs, and my house used to smell like dogs when coming in from outside. Not anymore. These filters are fantastic. I will never use another brand ever.
I began purchasing these filters last year and cannot say enough nice things about them. Our house is cleaner and fresher so much so when an air quality test was run earlier this year, our air was above any of their standards for needing an air purifier added to our heating and cooling system. Also, this is a company that goes above and beyond for their customers and truly stands behind their product. Very impressive!
Easy ordering, Fast shipping and great product.
Seems to be doing the job and holding up well. I am still watching for color change and if it lasts they the next 3-4 months, I will go for 5 stars!
I like these filters. I have not had a filter that truly lasts 3months before. I have 4big dogs and 2 cats and usually have to change the filter once a month even though the pkg said it was 3 month filter. It is nice to finally find one that is truly 3 months for my needs. Customer service nice too. I have not had an issue but did need to speak to someone as I had a few questions and they were answered quickly and efficiently. Happy buyer.
I’m on my second filter. They definitely change color when dirty. I only have vented air for air conditioner other wise I have boiler heat. I will definitely purchase again in spring
I have received requests to review the filters, and honestly, I would like to! The issue is that Colorfil still doesn't make the size I need for my furnace, so my order was cancelled. Therefore, of course, no picture, and I can't say how much more pleasant my home air might be. When you all can make filters wider than 1", I'd be happy to try them.
