To allow our team to spend quality time with their families this Thanksgiving, Gentex will be closed Thursday, Nov. 24, 2022 to Sunday, Nov. 27, 2022 and will not be processing any online orders. Thank you for your understanding.


To better protect workers exposed to respirable silica, the Occupational Safety and Health Administration (OSHA) has issued two new respirable crystalline silica standards:

  • Construction standard–Must comply with all requirements of the standard by September 23, 2017.
  • General Industry and Maritime–Must comply with all requirements of the standard by June 23, 2018.
  • Consult and review the regulations before starting any silica work.

Our PureFlo team can help you select the proper respirator to help protect your workers who may be exposed to the hazards associated with crystalline silica dust. Contact us today.
