Do-It-Yourself (DIY) Air Cleaners

USEPA has launched a new Do-It-Yourself (DIY) Air Cleaners webpage designed to help individuals, households, schools, and communities improve indoor air quality when commercial air cleaners are not available or affordable. This new webpage provides clear, practical guidance on when to consider using a DIY air cleaner, how to build one, and how to use it effectively—especially during emergencies such as wildfire smoke events.

What you’ll find on the page

• When to consider a DIY air cleaner.
• Easy-to-follow steps for building a DIY air cleaner.
• Tips for choosing the right design for your space.
• Operating considerations and safety tips.
• A short video demonstrating how to build your own DIY air cleaner.
