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 melt-blown fiber, activated carbon and spun-bond 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.
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
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.

We take great care to ensure our
filters are made of the highest-quality materials available. We require each filter
to meet these standards:
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 Suitable for Medical or Industrial
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
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.
