* Three layers of cotton quilting fabric
* Filter pocket
* Draw string with toggle for quick on-and-off and adjustable tension
* Flexible bridge-of-nose wire for airgap-free, personalized fit
* Comes with one medical grade MERV, reusable filter
* Home-made with love
* The MERV 16 filter is medical grade, on-par if not more effective than an N-95 mask material. It has three layers of media for optimum efficiency, which have been pinsonically welded together. It is hospital-grade and made in the US. It captures particles as small as 0.3 microns, with level 4 microbial resistance.
* Though this mask is machine-washable, I would recommend hand washing. Before washing, REMOVE THE FILTER as contact with water will make it no longer effective.
