We have observed in some endoscopy centers the practice of hand processing their endoscopes.  Some centers protect their scopes and patients by using expensive bottled sterile water.  We have observed however, it is the common practice in many centers of using unfiltered city water during the hand washing and rinsing process.  Considering all automated endoscope reprocessors use ultra-filtered bacteria free water to wash and rinse the scopes, it would seem only logical the same criteria should be used in the hand washing process.  Medical Filter Supply is now offering a water purification system designed specifically for the hand wash process.  Using properly filtered grit and bacteria free water can extent the life of your valuable endoscopes and provide a bacteria free endoscope for your patients.

The MFS water purification system is a complete unit, ready for installation.  It comes with an easily installed wall mounting bracket, filter canisters, sediment filter, bacteria retention filter, tubing, connectors, and a 2-way diverter valve to be attached to the present faucet outlet.  This 2-way valve allows the facuet to supply both filtered and unfiltered water with the simple turn of the control lever.  This diverter valve allows continued normal use of the sink when bacteria free water is not required.
