Supercharge Your Mask.
A PM2.5 filter adds a layer of electrostatic protection to your Puraka mask. The professional-grade meltblown fiber and activated carbon layers work together to create a "static cling" effect laboratory tested to capture the smallest airborne particulates, while the spunbond polypropylene recommended by the CDC for use in protective face masks adds additional mechanical and "triboelectric" filtration. Three materials, five layers, one trusted source for certified PM2.5 filters.
Protective inner layer of breathable, moisture-resistant polypropylene
Lightweight but tightly-woven 100% cotton shell
Extends under the chin for better fit and performance
Adjustable ear straps for near-universal sizing
Nose clip for improved seal and less fogging of your glasses
Rear pocket accommodates optional carbon pm2.5 filter
Seamless, non-valved design safe for others even without a filter
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.
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 meltblown 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.
Composition by Weight: 40%
Characteristics:Spunbond is a non-woven fabric that filters out larger particles, while providing structure to the inner meltblown 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.
