More Filtration, Less Discomfort | Puraka Masks are designed for enhanced, every-day protection suitable for use in an active or seated workplace setting. A Puraka Mask + filter achieves significantly more filtration than a cloth mask alone, but with less inhalation resistance and corresponding heart strain than a professional respirator (learn more).

We Know Masks | Puraka is an American company based in Seattle, Washington, founded in 2018 after the West Coast wildfires. As one of the only pre-COVID mask makers in the United States, we serve on the ASTM / CDC committee that developed the national standards for protective cloth facemasks. In short, we have the experience to know how to make a great mask, and what to look for in a filter.
Composition by Weight: 40%
Characteristics: High quality melt-blown fabric is the most important part of a particulate filter. Non-woven fibers act as a physical barrier against microscopic particulates while also providing an electrostatic barrier to stop aerosolized nano-particles.
Characteristics: Spun-bond is a non-woven fabric that filters out larger particles, while providing structure to the inner melt-blown layers.
Activated Carbon Fabric
Composition by Weight: 20%
Characteristics: Activated carbon fabric traps particulates via a process called adsorption, and also serves as an antibacterial and deodorizer.
Special Note for Valved Masks
Valved masks must be used with filters, and are not permitted in some areas. Using a mask with an unfiltered valve is dangerous to the people around you. Please don't do it.
Not a Medical Mask
A Puraka Mask is not designed as nor intended for used as a substitute for medical face masks and respirators used in a healthcare setting. Although our PM2.5 filters are manufactured and tested to N95-equivalent standards, the masks are not appropriate for industrial use.
Testing & Certification
Our disposable PM2.5 filters are tested to meet multiple filtration standards, including the European Union's EN 149:2001+A1:2009 standard and China's GB2626-2006 KN95 material standards, functionally equivalent to the United States' N95 standard (the US does not provide certification for non-sealed respirators). Puraka also relies on independent laboratories to test, certify and verify that our filters exceed performance specifications.
The most important thing you can do to prevent catching (and giving) viral infections is to practice physical distancing, avoid touching your mouth and nose with your hands, and to wash your hands regularly. A facemask is not a substitute for any of these mitigation strategies. A facemask and carbon pm2.5 filter will be highly effective against water droplets carrying airborne illnesses. Airborne virions travelling solo will be significantly reduced, but will not be completely eliminated.
