Filter Cartridges

Filter Cartridge Life

Several variables determine how long a cartridge will last. These include:

1. How much water you use, and

2. How much sediment, taste and/or odor, or other unwanted substance, is in the water.

Use the following information as a guide. However, no matter which type of cartridge you are using,

you will know it is time to replace it when you first notice the return of the unwanted substance in your

water. As a rule of thumb, an average family of four will use 1000 gallons of filtered water every 6

months.

Whirlpool Undersink Drinking Water Filter system model WHED10 with replacement elements

WHCF-GD05 and WHCF-DBl has been tested and certified by NSF International for the reduction

of protozoan cysts and chlorine. The rated capacity for this system is 1000 gallons (3785 liters) at a

rated service flow of 0.6 gpm (gallons per minute).

NOTE: A taste and odor cartridge contains activated carbon, a black powder. When new,

open the filtered water faucet and allow fine, carbon particles to purge from the

cartridge. Close the faucet when you no longer see the “fines” (carbon particulates)

in the filtered water, or approximately 30 minutes.

IMPORTANT: Do not remove housings with water pressure in the filter system.

1. Close the water supply shut-off valve to the filter. Open the filtered water faucet to relieve pressure

in the system.

2. Turn the housing off of the filter head, to the left, or clockwise. Be careful, the housing is full of

water. Do not lose the large o-ring seal.

NOTE: Filter wrenches are sold separately, if needed.

3. Be sure the inside of the housing is clean. Use hot, soapy water and rinse thoroughly.

NOTE: Always use soap and water to clean the Undersink Drinking Water Filter System. Do

not use vinegar or other acid based cleaners on this system as they will degrade some

of the system parts.
