Why use a filter with your Puraka Mask?

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.

Puraka Knows Filters | Puraka is an American company based in Seattle, Washington, founded in 2018 after the West Coast wildfires. We have the experience to know how to make a great mask, and what to look for in a filter.

We only list products that are ready to ship from one of our U.S. fulfillment centers in as little as 1 business day from when you place your order.

Why choose filters from Puraka?

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  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  Spun-bond Fabric

Composition by Weight:  40%

Characteristics:  Spun-bond is a non-woven fabric that filters out larger particles, while providing structure to the inner melt-blown layers.

Activated Carbon  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.

Important Safety Information

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.


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.

Passed the tests
My first shipment of PM2.5 masks passed both the H2O and Burn tests for authentic air-activated carbon filters. I'm reordering another shipment. Several shipments of PM2.5 filters that I purchased from e-Bay failed these simple tests and were clearly fakes, although they had 5-layer construction and looked absolutely real. Search YouTube for videos on how to test your masks for authenticity.

We are very impressed with this economic, convenient subscription where we don't need to worry about having the right number of filters to keep our family healthy and safe. What impresses me is the automatic refills of high quality filters that will protect us during this scary time both now and in our near future as we venture back out into a world of viruses that create both long-term pain or death for anyone unfortunate enough to catch it. I don't have to worry if we have fresh filters as they will automatically arrive at our doorstep each month. I feel very secure and safe knowing we will have these masks with current, fresh filters whenever we need them to stay safe. Thank you!
