DIY Make Your Own Cocoon Air Cleaner Kit

Build a powerful, affordable air cleaner at home—without searching for individual parts.

The Cocoon DIY Air Cleaner Kit includes everything you need to assemble a complete Cocoon using an air circulator fan and washable cotton batting. The fan pushes indoor air into the filtration bag, where the batting helps capture fine airborne particles, including PM2.5 from wildfire smoke.

Your complete kit includes:

• Compact air circulator fan
• Cotton batting filtration material
• Wire or plastic mesh support
• Reusable fastening straps
• Tape and fabric clips
• Scissors and measuring tape
• Step-by-step assembly instructions

Why choose the Cocoon?

• Helps reduce fine particle pollution indoors
• More affordable than many conventional air purifiers
• Quieter and more compact than a box-fan setup
• Uses washable, reusable cotton batting
• Simple to assemble with no specialized skills
• Includes all required components in one convenient kit

Easy to assemble

Position the fan so it blows upward, attach the mesh support, and place the cotton batting filtration bag over the structure. Once switched on, the fan fills the bag with air and pushes that air through the batting, helping filter particles from the room.

Place your Cocoon in the room where you spend the most time. Remember that portable air cleaners primarily clean the air in the room where they are operating, so additional units may be needed for multiple rooms.

Create cleaner indoor air with a practical solution you can assemble yourself.
