Water Filtration System

User’s Guide

1.  Remove all contents of the PITCHER, Filter Media Housing  

and Filter Media Packet from the packaging. 

2.  Please wash the PITCHER and all the PITCHER parts with mild 

soap and warm water.  Do not use abrasive cleaners. Oasis 

does not recommend washing the PITCHER in a dishwasher 

as the high temperatures will reduce the clarity of the plastic 

material over prolonged washing.

3.  Remove top of Filter Media Housing as shown. Open one 

corner of the Filter Media Packet marked on the package. Pour 

the entire contents of the package into the Filter Media 

Housing. It is normal for the Filter Media to be wet. Lightly tap 

the Filter Media Housing on the counter to get the Filter Media 

to settle. Snap the top back onto the Filter Media Housing. 

4.  Soak the Filter Media Housing upright in water for  

10 minutes. Place under a stream of water and rinse the 

housing under running water for 10 seconds. This process 

allows excess carbon dust to be released.

5.  Press the Filter Media Housing firmly down into the  

Reservoir Tube to ensure a tight seal. 

  6.  Attach the Lid. Fill the Reservoir with water. Allow all the water  

to filter through, and then discard it. Do this twice. The third 

pitcher of filtered water is ready for drinking.

Refer to   3   Filter Life Indicator. instructions for set up of the 

Filter Life Indicator to help ensure cleaner, fresher water. 

1.  Press and hold START for 3 seconds.  

“00” will be displayed. 

2.  Press the START key for 1 second. A count 

of 160 will be displayed on the screen 

and the counter will now be in the working 

status mode.

3.  Once the counter is in the working status 

mode, the counter will count down by one 

each time the fill lid is opened.  

If the fill lid is unintentionally opened,  

then you can correct the count by pressing 

the ”+” key to return the counter to the 

proper value. The counter will count 

down only when the fill lid is left open for 

approximately 7 seconds. Rapid opening 

and closing of the fill lid will not lower  

the count.

For Best Results:  

Keep the filter moist by maintaining the water level in the PITCHER 

above the bottom of the Reservoir Tube. Store the PITCHER in the 

refrigerator or in a cool location. If the water has been sitting for  

several days, discard it and refill the PITCHER with fresh water.
