We made and donated over 1000 opaque 3D printed masks that have been fit-tested and and particle tested with great results. Using the same shape and fundamental design, we spent 4 months designing a transparent mask that fits better, has more airflow and better filtration.
For masks sizing: measure down from the bridge of the nose to the bottom of the chin. Don't follow the curve, make sure to measure in a straight line, see photo.
This is how the sizes relate to the measured length:
- XL : length >= 5"
- L : length 4.5"-5"
- M : length < 4.5"
We currently only offer the L and XL size and are working on finalizing the design for the M size.
It's recommended to daily replace the filters when in constant use.
For occasional use, weekly replacement is acceptable.
Recommended filter materials are:
- Filti : https://filti.com/product/filti-face-mask-material/
- BioDefensor: https://biodefensor.com
Anti-fog spray should be applied by using a microfibre cloth, spraying the cloth in order to not wet the mask's filters, then gently pat (not wipe) the inside of the mask with the humidified part of the cloth. Let dry overnight.
Recommended anti-fog products:
- Rain-X : https://www.rainx.com/product/glass-water-repellents-cleaners/rainx-anti-fog
Outside use of the mask in cold temperatures will cause condensation and reduced transparency.
NO GUARANTEES: This mask is not approved as N95 replacements and is not guaranteed to help against COVID-19 or any other disease. We have however done extensive research and the model we provide is the best we can create with our available tools and supplies.
IMPORTANT: This mask is fully handmade, including the cutting and trimming of edges and filter openings. There are inherent visual defects and imperfections that result from the hand-made process, but they don't diminish the day-to-day use of the mask and overall transparency
