Sterisil Valved Cartridge

Sterisil Cartridge


The Sterisil Cartridge is engineered to purify and treat municipal water connected directly to a dental unit. The Sterisil Cartridge removes source water contaminates, prevents hard water deposits within your dental unit and provides continuous treatment for dental unit water lines connected to municipal water. Cartridges last up to 1 year depending on municipal water quality and volume of water used.

The Sterisil Cartridge is available in two convenient applications. The Sterisil Valved Cartridge is designed to be installed in a cabinet, and the Sterisil Inline Cartridge is designed to be installed inside the junction box of a dental unit. The Sterisil Cartridge is the convenient and simple solution to dental unit water line treatment for direct plumbed dental units, and the only water line treatment cartridges that are EPA registered to produce dental water with less than or equal to 10 CFU/ml HPC bacteria.

Do I need to turn off the main water valve to change the Sterisil® Cartridge?

It depends. If you have the valved Sterisil® Cartridge, then no! It is designed with an automatic shut off valve! Simply unscrew the old Sterisil® Cartridge and replace it with a new one. If you have the inline Sterisil® Cartridge then you will need to shut off the main water valve to change this Cartridge type.

Why has my water flow decreased?

Water pressure may be too low or the deionizing resin may be expired. Use a Total Dissolved Solids (TDS) monitor to check the output water to confirm the TDS is near zero. If the TDS is greater than 10 units above the initial background level, the DI resin is expired.

How long will my Sterisil Cartridge last?

The Sterisil® Cartridge is designed to last up to 1-year; however this is dependent on source water hardness and quantity of water treated. The Sterisil® Cartridge removes all incoming dissolved solids so it is necessary to monitor the treated water to determine the actual useful life of the filter which should not exceed one year. This is easily done with a battery operated hand-held Total Dissolved Solids (TDS) monitor. Please note that existing mineral deposits in the dental lines will gradually be removed and will be detected on the TDS monitor. It is recommended that you determine what the baseline TDS level is with a new Sterisil® Cartridge so that you will have an action level to change the cartridge when the TDS reaches 10ppm over the baseline level indicating the deionizing (DI) resin in the Sterisil® Cartridge is about to expire.

Why has a strange odor suddenly come about?

The deionizing (DI) resin will start to give off an amine odor when the resin is expired.
