What is it indicated for?

The BluTube® Dental Unit Water Purification Cartridge is for use on dental unit water lines attached to the dynamic dental instruments, i.e., high-speed handpiece, three-way airwater syringe and ultrasonic scaler. This cartridge in conjunction with currently recommended practices regarding sterilization and flushing of dental instruments reduces bacteria from the water supplied to the instruments to less than 200 CFU/mL, a level that will meet or exceed the current American Dental Association (ADA) recommendations for water quality.

Indications for use as stated in the FDA summary.
