During the initial phases of this project, I interviewed a team of maintenance workers at school district 15 along with data provided by OSHA. Through our research, we found an opportunity to redesign a respiratory mask. The only constraint was to utilize asknature.org by the Biomimicry Institue and develop a biomimetic solution.

I decided on a mask similar to a "neck gaiter" or "Buff". This way, we have an intuitive design that can be worn throughout the day and be pulled up as a respirator when need. This feedback was gathered through my second visit to their office where I was able to test my models directly with the people who would be using the product.

For the final design, I chose a hemp, cotton, and Lycra blend from Hemptraders.com I chose this specific fabric because of the benefits hemp provides including UV protection, antimicrobial properties, and environmental impact. Combined with a high-efficiency particulate absorbing (HEPA) filter and carbon filter, this mask becomes the first line of defense against silica particles and fumes.

Upon further reflection of this project, by taking it a step further, I would design the filter component to ensure an airtight seal on the wearers face as well as a solution to replace the filter. Secondly, I would eliminate Lycra from the knit OR find a waste management solution to separate the biological materials from the technical materials based on cradle to cradle principles.

And to take it even further -- as an honest refection of my work, I believe this is merely a bandage to the problem. Real innovation and change is taking place at the chemical level where scientists are reworking what are roads are made of. Take a look at the steps taken by Iowa State's Institute for Transportation in creating a bio-based solution. Steps like this decrease out reliance on fossil fuels.
