Makes the whole house feel fresh.
fast delivery, haven't switched out yet, my old filter is due in about 1 more month. These look like good filters.
It’s been amazing! I honestly had a musty dryer, damp smell coming from the ac in my new house I moved into. It was so bad I thought I might have to sell the house as I’m really sensitive to smells! At my wits end, I found your filters and haven’t looked back. No more musty smells! Thank you!
I have a house with older wooden floors. They tend to have a funky smell, especially when it's humid. Which it usually is. These help a ton. I can tell when it's time to change the filter just by the smell in my house, but the filter is always yellow like it should be. A bit pricier than the ones in regular stores, but fast shipping and great results.
Love this product! I originally purchased it because I wanted to see if they can reduce the cat litter odor but I got an unexpected bonus. I noticed the a significant reduction in dust on my furniture! It works!! I will definitely use this product from now on !!
Thank you Serionix team ! Colorfil filters have been an excellent investment at a great price for our home. House dust has decreased, and our home no longer has dog and lingering cooking odors. It’s so nice to come in after work and not “ smell something “ . We are now ordering 6 month filter delivery.
loving it & keep up the great job!

We have 4 dog's. 2 long hair and 2 short hair. Plus all the dust around here from outside. I wished I would of started using these filters a long time ago. I would recommend these filters for any one who might have alergeries or pets in the home.
My wife has bad allergies. I purchased the filters and she did not experience allergies while at home. I highly recommend these filters.
Changed color 1st week. Understand it may be my air. We have both dogs and cats but I can’t afford to change them often. We live on SS. Good luck with your products
Best air-filters for indoor air-conditioning units money can buy. The only information we trust coming from NASA brought to you by COLOR-FIL
Absolutely love it! Removes from the air., works as advertised.
I have a chronic cough and two very hairy dogs. I really feel the difference and experience less coughing. I put this in July 17 & on august 27 it was just orange with 50 % more life left.
Outstanding! No longer necessary to try finding air filter deodorizer! Colorfil filters are economical and keep our home smelling fresh! ( we have 2 dogs) Have noticed a reduction of house dust! Thank you ! Karen
I took a chance on Colorfil after having used another filter subscription that failed to do what it promised. The Colorfil filters are well made and the fact that they let you know when it is time to replace them is a great feature. I have noticed that the air quality in our house is better and fresher. We have 3 pets, so there's a lot of dander and odors and both have been reduced. My first order arrived quickly but the box had been damaged in shipping. I contacted customer service just to let them know and they not only apologized but replaced the two damaged filters. I am very happy with the filters and the product and highly recommend Colorfil.
I have definitely seen a difference in the air quality of my home since using these filters!
The ordering was easy but I was sent the wrong size. The speed in which Colorfil corrected this was great
It seems to be working alright. They are expensive so I only purchase when a good sale is on. I will keep trying them for the next few months, but so far they seem to do what they advertise. More sales please. Thank you
Living in a condo subjects us to various unwanted odors not of our making. Colorfil HVAC filters have totally eliminated those unwanted odors. The color changing filter material makes knowing when to replace the filter a no brainer. We are now loyal Colorfil users.
Good price and awesome shipping. Haven't had it in use very long but the house smells fresher!
Was curious about these filters, so I purchased. So far, I am pleased. Love the fact that they change color whenever filter needs to be replaced. Since I was pleased, I ordered for my daughter’s home also. She has dogs, but I think the “doggy” order is less after installation of these filters! Thank you for a great product. Kathleen Menaker
Love this filter. Less sneezing in the house no bad smells. And the filter tells you when to change. What else can you ask for.
Really need to print an airflow arrow on the edge indicating which side should be in / out for best airflow. Unless it doesn't matter, in which case you really need to print on the edge that it doesn't matter which way it is installed.
I tried the the Colorfil filters and they have worked very well. It really did make a difference in eliminating odors. I will order again.

The idea of color changing is a great idea, however, checking the color of the filter is not a simple or convenient process. My filter is not an easy access, so I check it (here in Florida in the summer time) every two months since a/c runs many hours a day in summer. It was good information about still working even if color has changed from the pink to some shade of yellow.
Great for homes with pets!!! I can really tell a difference in air quality since I began using these filters!
I love you filters! We have zero odor in our home from cooking, pets etc. I’ve used them for a few years and will never go without them. We get 2-3 months use out of each filter. Sometimes a little more!
We have 14 indoor cats, so these filters really have their work cut out. They turn yellow inside a week, so I doubt they've any long-lasting odor-killing ability (we're in Florida, however, so the AC is running much of the time). We also run a heavy-duty HEPA air purifier. Speaking of which, even with vacuuming on a daily basis, the amount of dust and hair and general greb these filters trap is alarming. I changed the first one out at 18 days. There was an email from the company advising that the early color change does not mean the filter is useless, just that it won't stop odors. Given that I bought it in the hope that it might have a long-lasting effect on odor, however, I'm not convinced it's really worth it for our household.
Seems to work fine does turn gold before the month is up, did same thing when in second month.
This one seems to be losing its’ pink color fast. (Replaced the end of May).
I have pets and industrial pollution, abd this filter is better than febreeze plus merv 1000 and charcoal. I love it.
doesn't really help with pet odors. Won't be buying again.
Love your product you know how long the smell of cooked bacon lasts not with these filters.
Work as least as well as the top line filters I used previously. I plan to keep buying. Have been installed only a couple weeks.
It was only pick 6 days. Not worth the money.
When I saw the ad, it clearly stated you knew when to change your filter by the color. Said it removed odors and many more miraculous things. Sadly that is not the truth. I complained the first time because in 10 days my filter was yellow and had to be replaced. (a lot of money every 10 days) then I got a response saying the original advertising was completely truthful. I should continue to use filter ( it would have deodorizing properties) just change it when it get dirty. Now I have gotten 2 more emails changing those rules again. If you don’t know what your product does and how it does it, how can you sell it?? These are very expensive filters and from my experience, just stick to the department store models. So much cheaper and no untrue promises
I have no more pet odors!! I love this filter!!
The part I love the most is knowing exactly when to change the filter....so easy to see the color change! It's my first filter change since my purchase....so excited to see how much it clears my air!
So far, we really like these filters. Lasts about 2 months in our house (with 2 big dogs and 4 cats). Seems to help with our allergies and dust. Previous filters caused ductwork to have a constant low rumbling sound, but now virtually silent with Colorfil filters. Love them.
I was surprised when I realized that my house did NOT smell bad! I have THREE dogs and one is a new puppy who is not quite “trained” yet so smells are not uncommon in my house. Surprisingly however, my house is now “smell-free”! The filters did change color quicker than I expected but the house still smells great so I’m not gonna change it until a month or so has passed. Thanks!
Bought it and it seemed to turn yellow quickly and no noticeable difference
These filters are 100% as advertised. I'm lazy about filter changes, but this motivates you as when I walk down the hall and look up I can SEE if it needs changing... So no more procrastination! Also I've noticed my allergies don't hit me until I step outside. So it is doing a great job!
I just moved into a house where the air ducts were cleaned, and I had the ultra allergen high merv rating Filtrete filters installed before I installed these colorfil filters. In addition, I have 2 hepa air purifiers which run almost constantly. I do not smoke nor do I have pets. I give this background to show the colorfil filters were installed into a home which should have pretty clean air already... Both colorfil filters were completely yellow within 2 weeks of installation. Perhaps they work, but I do think the color change aspect is a bit of a gimmick due to this experience.
I ordered a custom fit filter for my unit. The fit was tight, which is probably a good thing. The filters I have been using are kind of hard to keep in place as I close vent door. Anyway I am very pleased with the colorful new filters. I have cats and these filters seem too keep air cleaner and fresher. Will definitely buy more. Love that color changes when time to change!
easy to buy and inexpensive
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!
