How To Wear Step by Step:

BUFF Filter Masks are worn properly by covering the nose, mouth and chin of the user. Face masks should mindfully be put on and taken off in order to prevent self-contamination.

  1. Before putting on the mask, wash your hands thoroughly with soap and water or with an alcohol-based solution.
  2. Place the filter in the interior mesh pocket of the mask with clean hands as instructed. Ensure that the filter is completely flat and fitted into the shape of the inside pocket and does not protrude from the upper edge of the inside pocket.
  3. Properly place the mask against your face, ensuring it covers the area over you mouth and nose.
  4. Place upper strap on head and adjust the mask on nose and ears.
  5. Place on chin and adjust back of neck straps.

BUFF Filter Masks can be easily adjusted for a custom fit. Comfortable upper and lower back-of-head elastic straps are adjustable and eliminate discomfort behind the ears.

Cleaning & Care:

BUFF Replacement Filters provide 98% Bacterial Filtration Efficiency up to 24 hours of use.

Upon removing the 3-Layer BUFF Replaceable Filter, it is recommended to wash the BUFF Filter Mask with hot water to ensure total disinfection.
