Good product. My only complaint is. Even though the measurements are the same as my air conditioner. 20 x 20 x4. It is not as thick as the opening in my unit. It does fit but, it does not fully cover. I believe it’s not working as it should. ♂️
I appreciate the visual information on the status of the filter; it gives me more confidence in the effectiveness and the need.
These are the perfect size that I can not get in stores. I have to buy this size at the place I bought the furnace or I could get a smaller size at the stores. This way I can get the normal size and it will take care of the filtering for four animals in my house. I think it has really helped filter the air. I don't notice any smells. It only lasts a few months at my house before the color changes. I do not smoke. Just the animals. Two dogs and two cats. My son has allergies and he seems to have a little fewer problems.
I ordered the wrong size. It was returned & I received the correct size. Great customer service. I love the filter. It does seem to have a more clear feeling. Thank you.
These are by far the best filters I have ever used. I love that they change color to let me know it's time for a change. Will always buy from now on. Love this product.
I bought these without any real data or info to show they’d be effective but…they’ve been amazing! My house smells SO much fresher with these air filters installed!
Works really well
I recently moved into a new construction home and the builder warned us we’d be living with dust and some odors as the house settles in. The Colorfil filter proved them completely wrong. I’ve never had a more dust-free home in my life. The smells from the new paint, carpet, and wood floors were noticeably reduced in days. I have a uhoo air quality monitor so I can actually validate by seeing the voc and pm 2.5 concentration decline as the filter works its magic. The filter is now a pleasant salmon color so I can tell it’s doing it’s job and I have more life left! Thanks Colorfil for making the air in our new home comfortable and safe!
These come in a hard-to-find size for my furnace. I ordered a smaller size because that is what the furnace guy wrote down but that is so I could find it in stores. They seem to do a pretty good job and last almost 3 months in the wintertime with my four critters. I believe my son has noticed fewer problems with his allergies. Definitely going to order again.
I bought 2 Colorfil 16x25x5 filters to try out and see if they really did work as advertised. We live in a old historic house in N.C. and it has a tendency to be a bit musty at times. Since installing the one filter we have noticed a difference in the air quality in the home. I will definitely be buying again!
We have 3 long hair dogs and one short hair dog... we also live out in the country, small farm, dirt and dust everywhere. These filters have made such a positive impact on our home and our breathing, they are amazing!!!!! Allergies are not as bad as they use to be and not as much dust in the house anymore. We will continue to use these filters....
We like these filters well enough to order it twice with the wrong size;..-( Can't use the wrong size filters since we replaced our 21 year old HVAC system. Changed from all electric 9 seer heat pump to 17 seer efficient non-heat pump AC, and 96% efficient heating with propane. The difference in heating can not be overstated. Our electric bills have been a third of last years cost. But wait this is about a filter...First the quality of the filters regardless of size is top of the line. Airflow is great, dust is a minimum with the Ion scrubber and Colorfil filter. Made in the USA, can you believe it, we can actually buy a product that is produced right here! Sometimes you can have your cake and eat it too. Great job Colorfil!
Phenomenal! The color effect makes replacing filters so easy and my HVAC technician loves that I use Colorfil to keep my unit clean.
Our house was built in 1999, and had the original gas furnace in it until Christmas Eve of 2020 when we replaced the entire HVAC system. We also have four dogs - everyone who visits our home says there is no “doggie smell” but I’m paranoid and want to keep it that way. I was looking for some high quality filters to protect our new furnace, keep our home smelling fresh and reduce allergens. Colorfil popped up on my Facebook and I was immediately drawn to the color changing feature. I try to change our filter monthly, but life is so busy I have trouble remembering whether I changed it or not. These filters take the guesswork and guilt out of furnace maintenance. This picture was taken today after five weeks of use. My home feels cleaner, smells cleaner AND I’ve been able to stop taking my OTC allergy meds. I’m SO thankful for these filters and will never use anything else!
Filters came quickly and I noticed an improvement within the first week!
These folks are outstanding. Had an issue where my first box had been damaged in shipping- and this team had a replacement headed my way in hours. The filters have already made a noticeable difference within the first month of putting one in place! Highly recommend them and am on my mom and sis to try them too!
Love love these filters. Makes the house smells disappear!!
I ordered 4x25x16 filters. A Honey well fit tight with no gaps. Your filter has about a 1 inch gap between it and the fan. Why?
Filter seems to work great. Noticed the smell in the house changed, not that it was bad but seems a little cleaner smelling
Filter works great. I originally bought 4 inch filter since that was what was on my furnace. Turns out that actual sizes vary from manufacturer to manufacturer. After one email to customer service a new 5 inch filter was on its way. 5 inch fit perfectly. Filter works well and customer service was excellent.
I'm very impressed with these filters. They do exactly what say they would! Thank you very much.
First off, the filter width I received was 3 5/8” which is odd since I requested 4” width. Because of this, I am concerned that some air will bypass the filter and go around it since the fit is not snug with a considerable gap. That said, the performance is monumentally improved. I was using MERV 11 or 12 filters from Honeywell and 3M and they both did not capture or filter as much particulate matter as the Colorfil filters do. There is far less dusting to be done AND MOST IMPORTANTLY, the musty odor that used to come through the vents has vanished! My olfactory senses have always been acute and I smell everything, good and bad, that some folks don’t even notice. It was so disappointing that a new home build with upgraded A/C systems would produce a musty, dusty, and sometimes, gym sock odor or allow them to come through. Those stinky days are over and that has been the most valuable feature for us; that removal of all odors. I stand near the vents and breath the air and the cool, forced air, is crisp and clean! Great work y’all! We need to figure out why the odd sizes though, because we intend to use your filters exclusively!
Love how well they clean the air (it even smells better!) and I do not have to worry about when to change the filter, just look at it and KNOW when it is time by the color!
