If you live with pets, you know the struggle—loose hair, dander, and unwanted odors can quickly take over your home. High-efficiency particulate air filters help, but they don’t do much to tackle poor air quality caused by pet smells. That’s where Colorfil comes in. Designed specifically for pet owners, this innovative MERV 8 HVAC filter not only captures common allergens and pollutants but also changes color to let you know when it’s time for a replacement. No more guessing or sticking to a schedule that may not reflect your home’s actual needs! With a commitment to helping homes with pets achieve cleaner air, we like the way Colorfil looks at things from a molecular level.

A Simple Switch = Cleaner Air

Swapping out your HVAC filter is one of the easiest things you can do to improve your home’s air quality—and if you have allergies, it's among the most important things you can do year-round. Colorfil has won competitive awards from NASA, and simply put, it's a smarter, more effective filter.

"Managing air quality at home doesn't have to be complicated—Colorfil makes it simple," shares Dr. James Langer, CoFounder + President at Colorfil. "In addition to capturing odors, allergens, and pollutants, our air filters are designed to change color from bright pink to dull yellow to indicate when it's time for a replacement. This technology, called color-shift™, eliminates the guesswork, helping consumers stay on top of their indoor air quality without relying on arbitrary replacement schedules. With a Colorfil filter, homeowners can easily manage their indoor air, ensuring a cleaner, healthier living environment tailored to their specific needs.”

What Makes Colorfil Different?

Most HVAC filters trap dust, mold spores, and particles, but Colorfil goes beyond to actively removes pet odors and airborne contaminants that traditional filters miss. This is especially helpful for households with multiple pets or anyone sensitive to allergens. Plus, while most brands recommend scheduling a calendar reminder for swapping your filter, Colorfil attempts to make it even easier to know when the filter is too old to be effective and efficient—it changes from vibrant pink to an unmistakable yellowish-orange hue.

  • Captures pet hair, dust mites, dander, and other airborne particles that can irritate sensitive noses
  • Neutralizes strong household odors from pets, cooking, and everyday life
  • Built-in color indicator changes from pink to a yellow color when it needs replacing
  • NASA-inspired air filter technology for cleaner indoor air
  • Works with most HVAC systems for easy installation (it's sold in a range of sizes that match regular most regular filters)

Say Goodbye to Odors and Guesswork

If you've ever walked into your home and immediately noticed unpleasant odors, you’re not alone in wondering what you've done wrong. Even the cleanest homes can develop lingering strong odors, especially from dogs, cats, and small animals. We also create fumes from household cleaners that use active ingredients and often-unwanted chemicals. Colorfil’s filters actively trap harmful air particles and neutralize smells rather than just masking them. That means fresher air without needing constant air fresheners or sprays.

And unlike standard filters that look the same whether they’re new or clogged, Colorfil’s color-shift™ technology gives you a clear visual cue. When the filter turns from pink to orange, you'll know it’s done its job and needs replacing. No more guessing about air quality issues, and no more wasting money replacing a filter too early.

If you want fresher air, fewer pet odors, and a simple way to stay on top of disposable filter changes, Colorfil is the upgrade you should consider.
