Supercharge Any Mask

Add a layer of enhanced electrostatic filtration to any mask, gaiter or face covering with these self-adhesive face mask filters. No pocket? No problem. This packet of five peel-and-stick filters come with small but mighty adhesive dots that hold the filters in place until you are ready to swap. The stick-on patches work on any fabric, don't leave a residue, and are practically odorless. The professional-grade meltblown fiber, activated carbon and spunbond polypropylene recommended by the CDC for use in COVID-recommended face masks work together to create a "static cling" effect laboratory tested to capture the smallest airborne particulates. For a mask to be effective, fine aerosol filtration is essential. It's time to make your mask work.

What makes a Puraka PM2.5 filter work?

More Protection, Less Discomfort | Puraka Masks + self adhesive mask filters are designed for enhanced, every-day protection suitable for active or casual use. Using a filter provides significantly more protection than a cloth mask alone, but with less inhalation resistance and corresponding heart strain than a professional respirator. Learn more.

We Know Filters | Puraka is an American company based in Seattle, Washington, founded in 2018 after the West Coast wildfires. Because we take safety seriously, we serve on the ASTM committee collaborating with the NIOSH division of the CDC to develop the national standards for COVID-recommended face coverings, and we work hard to ensure our pm2.5 filters exceed regulatory standards. In other words, we have the experience and know-how to make a filter that works.

Static Stops the Small Stuff | Your fabric mask might be effective at blocking larger particles, but fine aerosols are a different story. According to the CDC, particulates in the sub-micron range can remain airborne for hours, and because of their small size they tend to penetrate physical barriers easily. Fortunately, a peel and stick PM2.5 filter does an excellent job at trapping particulates of this size (approx. 99% standalone efficiency), making these inserts a must for effective filtration.

Why choose stick-on mask 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:

meltblown  meltblown Fabric

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 microscopic particulates while also providing an electrostatic barrier to stop aerosolized nanoparticles.

spunbond  spunbond Fabric

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  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 self-adhesive 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 stick-on filters are manufactured and tested to N95-equivalent standards, the system is not sealed nor intended for industrial use.

Testing & Certification

Our PM2.5 disposable self adhesive face mask 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 wear a mask, 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. Airborne virions travelling solo may be reduced, but will not be completely eliminated.
