Introducing The Cocoon: The Wildfire Smoke Solution That’s Affordable, Effective, and Ready for Everyone

As wildfire smoke grows more frequent and dangerous, millions of people are left breathing polluted air with no affordable way to protect themselves indoors. Traditional air purifiers are costly, hard to find in emergencies, and often rely on expensive filters that require constant replacement.

That’s why we created The Cocoon. It's a simple, powerful solution designed to help everyone breathe safer air during wildfire season and beyond.

Watch the video below to learn how The Cocoon works and why it’s changing the game in indoor air protection:

Developed by a team at Portland State University and winner of the U.S. EPA’s 2024 Cleaner Indoor Air During Wildfires Challenge, The Cocoon combines a washable cotton filter and a standard box fan to deliver rapid smoke particle removal—over 80% of PM2.5 pollutants cleared in less than 30 minutes. Field-tested and backed by science, it delivers the clean air performance of much more expensive HEPA systems, all at a price tag under $60.

Even better? It’s DIY-friendly and scalable, meaning you can build one from household materials during a crisis—or help distribute them to communities in need.

Whether you're looking to protect your home, support vulnerable families, or partner with us to expand access globally, The Cocoon is designed with accessibility, affordability, and impact at its core.

What Makes The Cocoon Different:

Proven Effectiveness: Independently tested to meet EPA standards for wildfire smoke removal

Affordable: Priced significantly less than comparable models, even with all-new parts, or build it from materials that are readily available 

Reusable: Washable filter means no costly replacements

Safe and Quiet: Designed for homes, schools, and community spaces

Scalable: Easy to produce, ship, or assemble locally in response to wildfire emergencies
