a Medical or Industrial Mask
Mask 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
masks are not appropriate for industrial use.
Special Note for Valved Masks
Valved masks must be used with filters, and are not permitted in public in some states. Using a valved mask without a filter is dangerous to your employees and your customers.
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
