R&B Fabrications is now producing a Pre-Filter Mask at the request of our local EMA Director for First Responders. The mask was created to extend the life of the N95 Filters. Our local First Responders have noted that the Pre-Filter Mask extends the life of the N95 Filters 3-5 times longer.

The masks can be worn without the N95, but they do not provide the required filtering properties to remove the COVID-19 virus without the use of the N95 mask. These masks can be used to help reduce the transmission of the COVID-19 virus.

R and B Pre-Filter Mask

R & B Pre-Filter Mask

:: Specifications

  • They are made of 10.5 oz Micro Fleece polyester material (the only material available at this time). They have 2 – ¼" x 12" latex-free elastic headbands (color may vary); and sewn with #46 nylon thread. There is a usage label sewn inside of the mask for reference.

:: Features

  • An extremely low-maintenance fabric, microfiber products are suitable for machine washing and tumble drying. The fabric develops static cling in the dryer, but fabric softener sheets usually mitigate the problem. We recommend hand washing and hang to dry overnight. UV light can also be used to disinfect the mask.
