These masks are not medically-approved, and we make no claims about their usefulness or effectiveness for any purposes, health or otherwise. The cushion is made of industrial rubber, not medical-grade silicone. Use at your own risk, and discontinue using immediately if you develop any signs of a reaction to to skin contact with this material.
Black elastic straps are pictured, but your order may contain white elastic, depending on supply.
Details and Features of the Masks:
These 2-piece respirator masks are 3D printed. The filter is held in place with a flexible TPU disk/grille that snaps into the inside of the mask, over the filter, and is easily removed and reinstalled.
The rubber cushion provides more comfort, and far less air leakage around the mask compared to typical 3D-printed masks. While an air-tight seal may be possible, we can't guarantee it, and face shape may determine how closely the mask fits your face.
For the grille, we chose the honeycomb pattern for its strength, which allows the maximum open area for airflow through the filter.
Elastic straps are provided, similar to the straps used in industrial respirators. The tightness of the fit can easily be adjusted by untying and re-tying the strap to change how much of it stretches from one side of the mask to the other.
Five (5) cotton filters are provided in a sealed bag. The masks are designed to work with 2.25" "cotton round" pads, which are easy to purchase, or you can make your own filters from cotton cloth, filter material, etc.
For cleaning, we recommend washing with soap and water. Harsh chemicals may damage the cushion. Filters should be changed regularly and used ones discarded. 2.25” cotton rounds are available on Amazon and elsewhere, or you can cut your own filters from fabric.
