We Know Masks | Puraka was founded in 2018 in Seattle, Washington, originally offering fabric masks to protect against wildfire smoke pollution. In 2020, we joined the ASTM subcommittee that developed the national standard for protective face coverings, F3502, in collaboration with the CDC's NIOSH division. 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 filter.
More Filtration, Less Discomfort | Puraka Masks are designed to offer everyday protection suitable for active or casual use. A Puraka Mask with our laboratory-tested electrostatic filters is engineered to block airborne particulates in the critical fine-aerosol range significantly better than most cloth masks, but with less inhalation resistance and corresponding heart strain than a typical medical respirator (learn more).
Our In-Stock 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!
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 airborne micro-particulates while also providing an electrostatic barrier effective against fine aerosols in the sub-micron range.
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 particles via a process called adsorption, and also serves as an antibacterial and deodorizer.
Not a Medical Mask
An F3502 barrier face mask is not a medical mask as defined in ASTM F2100, and not intended for use in a healthcare or industrial setting where a respirator is required.
Testing & Certification
Essential Masks meet 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 EN149:2001+A1:2009 standard and China's GB2626-2006 KN95 standard, functionally equivalent to the United States' N95 standard (the US does not provide certification for non-sealed respirators). Puraka 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 wear a mask, practice physical distancing, avoid touching your mouth and nose with your hands, and wash your hands regularly. A face mask 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 in the sub-micron range will be reduced, but will not be completely eliminated.
