More Protection, Less Discomfort | Puraka Masks + filters are designed for enhanced, everyday protection. Our filters are laboratory tested to block approximately 90% of aerosol particulates in the critical 100 nanometer range when paired with a Puraka mask. This makes them significantly more efficient than a fabric mask alone, but with less inhalation resistance and discomfort than a medical-grade respirator. Click or Tap to Learn more.

We take great care to ensure our filters are made of the highest-quality materials available. We require each filter to meet these standards:
Melt-blown Fabric
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.
Spun-bond Fabric
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.
Not Suitable for Medical or Industrial Use
A Puraka Mask + filter 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 system is not intended 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.
Reminder
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. Virions travelling via fine aerosols will be reduced, but will not be completely eliminated.
