We Know Masks |
Puraka was founded in Seattle, Washington in 2018, after the West Coast wildfires.
We served on the joint CDC/ASTM committee that developed the national standard for
protective face coverings, F3502. Our masks are tested in North American laboratories to
ensure they exceed the minimum filtration levels. In short, we
have the experience to know how to make a great mask, and what to look for in a
More Filtration, Less
Discomfort | Puraka Masks are designed for enhanced, every-day protection
suitable for active or casual use. A Puraka Mask with our laboratory-tested
electrostatic filters can reduce 90% of airborne particulates in the critical
fine-aerosol range, much more than a typical cloth mask, but with significantly
less inhalation resistance and corresponding heart strain than a medical respirator (learn more).
Guarantee | A mask is not something you should have to wait for. Every
product in our store is ready to ship from one of our U.S. fulfillment centers,
usually within one business day or less from when you place your order. We offer
free shipping on any order of two or more masks, or you can upgrade to USPS Priority or First Class for just $5!
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
Activated Carbon Fabric
Characteristics: Activated carbon fabric traps particulates
via a process called adsorption, and also serves as an antibacterial and
Not a Medical
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.
Our masks are certified to Level 2 F3502 standards, the US benchmark for protective
barrier face masks. Puraka's 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
The most important thing you can do
to prevent catching (and giving) viral infections is to wear a mask, practice
physical distancing, avoid touching your mouth and nose with your hands, and wash
your hands regularly. A facemask is not a substitute for the other mitigation
strategies. A facemask and carbon pm2.5 filter will be highly effective against
water droplets carrying airborne illnesses. Fine aerosols traveling solo will be
greatly reduced, but will not be completely eliminated.
