    Why does my Gentex Respiratory Product battery drain so fast?
    • T
      Tiffany WalkerAug 4, 2025
      If your Gentex Respiratory Product's battery life is shorter than usual, it could be due to several reasons. First, make sure the battery pack is fully charged. If the HE filter is clogged, replace it to reduce the load on the blower motor. Finally, the battery pack may be nearing the end of its service life, so consider replacing it.

    • M
      Megan WebbAug 26, 2025
      If the LED is flashing and the alarm is sounding on your Gentex Respiratory Product, it might be due to a system software malfunction. To attempt to clear the alarm, power down the motor/blower unit and remove the battery pack. Let it sit for a few minutes before reconnecting the battery pack and turning it back on. If the unit still doesn't reset, contact Gentex.
