The Colorfil Story
Meet the guys who made your air filter change color.
Colorfil started as a NASA-funded discovery — and turned into a mission to make dirty air visible. Here's Jim, our CEO, on where it came from.
The Science of Color-Shift™ Technology
The pink-to-yellow shift isn't a gimmick — it's chemistry at work. The main active ingredient in our patented coating is citric acid, which is naturally-occurring and commonly found in fruit. By applying it to standard filter material, our cofounders discovered this coating formula captured and neutralized amine-based compounds (think: household chemicals, urine, pet, food, paint, and other odors) 5x more effectively than the leading brand.
Beyond Clean Air
Our team is committed to creating clean, safe, and welcoming spaces for pets and their humans. That mission goes beyond the filter, which is why we support organizations doing the work firsthand, like K9s For Warriors and our local Champaign County Humane Society.
Proudly made in the USA
Our air filters are manufactured, packed, and shipped from Champaign, Illinois. This dedication to U.S. manufacturing allows for rigorous quality control, ensuring you receive a superior air filter.
