The only filter that eliminates chemicals and odors and shows you that it's working.

Yep, it's really that simple!

When the filter turns yellow, it's time to be replaced.

Our filters were originally designed for astronauts in space, and as such, meet rigorous standards. 

Now adapted for the home environment, Colorfil will help you and loved ones enjoy a cleaner and fresher smelling home.

Colorfil captures and removes 5x more odors, as well as other nasty stuff including:

Odor

Dander

Dust

Allergens

Chemicals

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 co-founders discovered this was 5x more effective at capturing and neutralizing amine-based compounds (think: household chemicals, urine, pet, food, and other odors) than leading brands.

Tech stuff: Our filters have received the MERV8 filter designation, which means that they’re amazing for the majority of household irritants—especially pet related. They’re also particularly great for reducing symptoms in those with asthma and allergies!

All air filters are impacted by things like humidity, temperature, changing seasons, and pets in the home. Colorfil is the only product that gives you a peek at what is actually happening in your filter, featuring a vibrant color-change proportional to how hard they are working: when summer heat and humidity ramp up, they’ll likely change more quickly; when weather cools and you aren’t using your HVAC system as much, they’ll likely take a lot longer to change color.

"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!"

"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. All in all, these a darn good filters, probably the best."

"We installed the filter and within one hour the smell was gone and it stays gone (even when she forgets to clean the cage). I am a complete convert — these filters are AWESOME!"
