Traditional supply channels for PPE have been overwhelmed, so we had to resort to DIY PPE.
One reason the demand for PPE is so large is because most PPE is designed to be single-use, creating a lot of waste.
If we have DIY PPE that is cleanable, and reusable, we can address the shortage of PPE by orders of magnitude.
Furthermore, it will make the PPE cheaper and more sustainable by eliminating trash.
Face shields create an initial barrier from patient spray droplets to the eyes, nose and mouth and facilitate N95 respirator reuse.2 Most face shields use foam, and generate enormous amounts of plastic trash. PhaseSpace Open Source Designs are:
- Cleanable and reusable, creating less trash. To clean, use one of the following methods3:
- Soak in Isopropyl Alcohol/Isopropanol 70% for 5 min or Sodium Hypochlorite (household bleach) 0.01% (1:10) for 5 min+
- UV-C 30w for 15 min
- Ethanol 70%+ for 5 min
- Easily manufactured using cnc machining and laser cutting. Quicker than 3D printing that takes hours.
- Minimized components. Conserves difficult-to-obtain materials for the shield; uses available colored plastic for headband.
What materials are these face shields made of?
The shield is made of 0.010” PVC plastic and machine stamped. The head piece is made of 0.060 ABS plastic and laser cut. The elastic on the headband is made of various material, but will primarily be made of polyester. This is not an NIH-approved shield.
What is the production process (sterilization, handling, packaging, etc.)?

Notes on DIY Face Shields:
Face shields can be made out of the following materials, and range from 0.030″ to 0.010″ thick.
- Polycarbonate (PC): Clear, bendable, most durable, heat needed to mould
- Polyethylene (PE, PET, PETG): high demand and hard to obtain, hospital standard
- Amorphous-polyethylene terephthalate (APET)
- Clear Polyvinyl Chloride (PVC)
The inside bend and front bend can be as thick as 0.0625″ and can be made of ABS or similar material if the materials mentioned above are not available.
Patients infected with Covid-19 may develop respiratory failure requiring endotracheal intubation. Since the virus is transmitted through droplets and aerosol, healthcare workers who are intubating these patients are at high risk of contracting the virus during the intubation process. Ideally the provider should wear PAPRs (powered air-purifying respirators) while intubating patients, which would provide the highest level of protection, but given the rising number of infections, there is a global shortage of PAPRs. Therefore, a lot of healthcare workers are only wearing face shields and N95 masks, if available, putting them at a much higher risk of contracting COVID-19. To protect healthcare providers from this virus during the intubation process, an intubation box effectively shields a provider’s face from a patient’s airway, while allowing the provider to move their arms freely to perform all necessary tasks during endotracheal intubation.4
All intubation box models in the table below are easily cleanable (allowing for reuse), cheap, and quick to assemble (if needed).

Best Materials for DIY masks:
The primary challenge of choosing a homemade mask material is to find a fabric that is dense enough to capture viral particles, but breathable enough that we can actually wear it.
The best masks are n95 which filter out 99.9% of particles followed by surgical masks.
Hepa filters are also effective at 99% but masks using this need to be made carefully because you want to avoid breathing in risky small fibers sandwiching them between 2 layers of cotton fabric.5
Best ways to Make DIY masks:
- Use one of the materials stated above or a quilting fabric made from high-quality, high-thread count cotton6
- Note that most sewing machines can handle only two layers of fabric when making a pleated mask
