Why Choose The Cocoon?

Developed for wildfire smoke and high-pollution events

The Cocoon is designed to help reduce airborne fine particles, including PM2.5, inside an appropriately sized indoor space.

Based on a nationally recognized design

The original Cocoon prototype was developed at Portland State University and selected as a winning prototype in the EPA’s 2024 Cleaner Indoor Air During Wildfires Challenge.

Designed around accessible components

The system uses a fan, a large fabric filter, and a simple method for keeping the filter upright and secured.

Washable and reusable

The Cocoon fabric filter can be washed and reused according to the provided care instructions, helping reduce ongoing filter replacement costs and waste.

Easy to understand

The Cocoon avoids complicated controls and multi-stage replacement cartridges. Setup instructions and compatible-component specifications are available on this website.

Multiple ways to get started

Purchase a complete kit, select the freestanding upgrade, buy a replacement filter, or follow our free instructions to make your own Cocoon using locally available materials. [You can also make your own with our DIY kit.]
