HeiQ Viroblock Reusable Face Mask with Carbon Filter

The 2.5PM Filter is a non-woven and melt-blown filter cloth, five-layer filter system effectively keep away from PM 2.5 and a range of airborne contaminants such as dust particles, vehicle exhaust, wood, pollegen allergies.

Airborne viruses like the Coronavirus are even smaller than PM2.5 (the Coronavirus's lipid envelope is about 120 nanometers across). However, research has shown the material to capture nanoparticles of a similar size with a high degree of efficiency (approx. 95%), and lab tests show a PM2.5 filter with a properly-fitted cloth mask can reduce airborne particulates by as much as 90%.

Disposable PM2.5 filters are flat, so they take up less space than standard respirators. They never lose effectiveness, and you can use them continuously for 20 hours or whenever it becomes harder to draw a breath.
