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.
It’s k I was supposed to get a discount and didn’t. I subscribed and it’s not showing up . I switch from another company to this company
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.
Switched to these filters for the house a several months back and am very happy with the performance. These are well made and fit perfectly. The previous brand I used was off a bit in size and a struggle to put in place. These fit perfectly and I am happy with the air cleaning performance.
Love these filters. So easy to know when to change. They come quickly and are the custom size for my strange furnace!
I have 5 dogs and it's really helping with the doggy odor
Leigh Ann C.
It definitely takes care of pet odor however there is something that is very irritating to my lungs at first and I believe it's the smell of the cardboard. With the other filters I used previously the cardboard doesn't bother me but yours is rather strong and it my my lungs hurt. After having it for a while it calms down and is okay but it took 2 weeks for that to happen. Please do something about the odor that your filters emit.
I saw an ad for colorfil in the past. I was skeptical plus the price was off putting. Well fast forward six months and a need arose I revisited colorfil I decided I’d give it a try. So far so good. I’m happy. I’ll be using this filter from now on it’s only been in my furnace for two weeks but it’s working well so far
These filters are the best on the market for pet odors. I have 3 large dogs so I am grateful for this product. I chose the subscription plan so I never run out!
I started using the Colorfil A/C filters in January of this year because I moved in a freshly-painted home which had some paint odor issues and I also have two beloved house cats...the paint odor disappeared and I never notice my litter boxes at all. Very effective product!
I ordered 6 of these air filters and received them very quickly. I place the first one on July 1 I checked it on Aug 1 and the filter was still pink and clean. I then checked again today Sept 1 and the filter is still pink! I also want to add that I haven’t had to dust very often and plus my house smells are good with two dogs living inside. I highly recommend this filter! I know I’ll never buy a different one since using this one. A very good buy!
These work great with the smells (I have 3 dogs). The only problem is that I'm on my last one and the company has been out of stock of 24 x 24 size for weeks! I placed a subscription order on July 5 and the status is still "unfulfilled."
These filters are fabulous. So happy to have learned about them!!!
I love Colorfil by Serionix. My first time ordering, they double checked the filter size before they fulfilled the order. Their customer service is top notch. The filters are great, I especially love the visual reminder to change the filter (it actually works!) I feel like my air quality is better. My kids started sleeping better using Colorfil. Overall I give
I work in animal rescue, so my house is always filled with animals...and lots of ammonia in the air! I really love these filters the customer service is A#1
Excellent air filtration! We are post construction and still heavily cleaning with kids and pets. No complaints here!
Amazing filters. We don't necessarily have an indoor cat issue, but we do have an outside cat issue. It sprays outside our window, and 'that' smell permeates through into my office. Within a day, that smell is nearly eradicated. All cooking smells are also taken down to near zero. The air simply smells cleaner. My wife cleans our house since I cannot stand any chemical or scented cleaners. I literally just found out today that she had done it 3 days prior, and I never noticed any smells that day. They will tell you when to change them. It turns to yellow when it's seen its end-of-use. Can be anywhere from 30 days to 6 months... I'm curious to see my own usage mark. Very happy with these filters. HIGHLY Recommend.
Great customer response and lightning fast shipping!
I decided to give these filters a try after I saw them on Facebook, I checkout out their website and was amazed at how high quality and low cost they were. Are these filters too good to be true? I live in an older house and have a cat. I requested an estimate to get my ducts cleaned a couple years back, $3,000...who has an extra $3,000 for that! I have tried the all the more expensive and better filters that the hardware store has to offer, so why not give these a try? They are very affordable! I received my order right away. I put my filter in one night before I went to bed and the next day when I came home from work and walked into my house, I noticed a difference. That fast. I am sold on these filters!
Found their filters when I was doing some research and shopping around. I was originally just getting normal ones from the store but as time went on our apartment started to get that "lived-in" odor. Nothing bad or anything, but 3 people and a dog don't help keep the air fresh, especially in the crazy times! Thus my need/want for a better filter. I was going to try some carbon filters for the HVAC but didn't like the idea of little bits of carbon falling off and getting sucked in. My internet searching brought me to these, and my curiosity overtook me and I had to try them. Now, I love them, and have helped my family try them as well, we're hooked! They really do change colors when it's time to replace, and they really do work as they say, removing smells and chemicals etc...The team/company is also very helpful! Had some questions and they quickly responded! I'm now excited to try their future products in time! Overall I highly recommend them!
I just ordered these last week, they shipped the same day which was amazing. I installed the first one and within just a few days I notice a difference in the house. Thanks so much. Great product.
These filters are legit and the only filters I use in my home. I love the technology in the filters, I love the easy way to tell they need replaced and I love that they donate to their local animal shelter for every filter sold. Lauren is so helpful too and has helped me many times when ordering and answering questions. Do it, try these. Best filters ever!
Awesome filter. House smells great! Our house is small so even with the hood vent, if I do a lot of cooking you still smell it in the morning. Not anymore!
Everything from innovative product, to fair prices, to stellar customer service! Highly recommended!
Excellent technology and very simple to determine when to change filters.
I have to say these are the best air filters out there! We were having alot of problems with dog and rabbit smell. Process was very easy to order, I originally purchase the 16x20x1 but when filters arrived I notice they were to small for my furnace. Emailed customer service and they answered me in less than 30 minutes.... Explained to them that my filter size was actually 16.25x21.50x1, a little bigger! They sent me a free return label and within 3 days I had the correct filter size. Installed these filters on a afternoon, by the morning the smell of dogs was gone! Hope this review helps alot of people!!!
We received our filters in October of last year and can tell a difference in air quality and odor control. This company goes above and beyond for their customers.
I really love these air filters - they seem to work well for our home! I found your filters online after taking in a litter of kittens, failing as a foster mom and keeping them all instead of finding them homes elsewhere (they were way too cute to part with ), and then finding out that I’m allergic to cats . The filters have helped with my allergies. Plus my house literally smells like nothing, which is awesome after being worried about potential pet smells from keeping all of those kittens. So glad I found these!
I received my order 2 weeks ago and I immediately installed one of the filters. We own two big dogs and it is difficult to keep the house smelling fresh all the time. I didn’t know what to expect out of these filters, but I have to say that I am totally impressed by them. They absolutely do the job that they’re supposed to do. I was able to tell the difference in my household air within 24 hours. I am completely sold on these and you will have a customer for life. Great filters for sure.
I have 6 pets, live in FL so I don't get a chance to open the windows for fresh air. So needless to say smells are an issue. I also had this weird mildew (inspected for mold and there is none) smell from my unit. I have had the ducts cleaned, coils cleaned everything... There was still the funky smell. So I tried these filters I noticed a difference with in a day. I wish these were around when I spent all that money on cleaning. I also notice cooking smells don't staying around as long as they used to.
I run a dog rescue, house full of dogs is always an issue with smells, I have tried everything on the market, candles, cleaners, air cleaners, sprays, air fresheners, nothing really works. These filters have made the biggest difference so far. Very happy with them the color change is just an added convenience.
Colorfil filters really do the job on cat odors!
