Many people are at risk for exposure to the COVID-19 virus and cannot afford to get infected. These people can isolate themselves, but often, their professions or requirements for daily life will take them in contact with other people, and they need some form of protection. Masks definitely help, but can become uncomfortable to wear, especially over long periods of time. This guide will walk you through creating a Powered Air-Purifying Respirator, which will protect the wearer and those around them from airborne viruses and bacteria, while at the same time providing positive airflow to the wearer’s face. That airflow makes sure that the wearer has a supply of fresh, clean air that has gone through a filtration process, and, in our tests, is the equivalent of wearing an N95 mask.

What is the reason to make one of these instead of wearing a regular respirator? They mention N95 masks being less comfortable, but this thing looks like the part that straps to your face is basically the same as a respirator. Just instead of filters you have to draw air through there’s a fan, but why do you need the fan?

During the pandemic, access to such PPE was difficult. Providing an open source design for the respirator allows for decentralized manufacturing by citizens to take place, resolving the bottlenecks of centralized production and increasing accessibility. The filtered air provided by the fan is for comfort, it is much more comfortable to receive the flow of air from this mask than using an N95.
