The Origami Respirator is a concept intended to address the shortage of PPE (Personal Protective Equipment) within hospitals and other care facilities.

Below is a video showing how to make a respirator using a vacuum cleaning bag, a zip tie, and 2 rubber bands.  The process entails the following steps:

  1. Downloading template files for flat pattern (See embedded form)
  2. Trace template on single-ply vacuum cleaning bag material
  3. Complete the origami fold sequence described in the video
  4. Use zip tie to secure respirator together
  5. Attach rubber bands for ear clips

(Big thank you to Tony Gnau at T60 Productions for video editing support!)

The vacuum cleaning bag was chosen due to its sub-micron filtration and high flow rate capabilities.  Alternative materials may be suitable for this origami respirator design.  Below are a number of materials provided by Smart Air Filters.  As illustrated in the chart below, Vacuum Cleaning Bags have 95% effectiveness compared to Surgical Masks at 97% effectiveness against 1-Micron particles.

As discussed in the video, the Origami Respirator concept has not undergone the extensive safety and efficacy verification that would be required for a regulated medical device.  As such, it is not currently approved by FDA or any other regulating body.  

To download the template files, please use the download form embedded within this page.  If there are questions or comments, feel free to send us an email.  Thank you for helping resolve the PPE shortage through the coronavirus crisis
