The US Environmental Protection Agency (EPA) demonstrates how to build a DIY air cleaner of your own that can be used during emergencies, such as wildfires, and in other situations when products of known performance (like commercially available portable air cleaners) are not available or affordable in the video, “Do It Yourself! How to Build a DIY Air Cleaner.”

Note: The EPA does not recommend DIY air cleaners as a permanent alternative to commercially available air cleaners.
