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

take great care to ensure our filters are made of the
highest-quality materials available. We require each
filter to meet these standards:
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
Characteristics: Spun-bond is
a non-woven fabric that filters out larger particles,
while providing structure to the inner melt-blown

carbon fabric traps particulates via a process called
adsorption, and also serves as an antibacterial and

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
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
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.
