Not at all. Carbon cartridges contain trapped air which is released as the water permeates the cartridge. The cloudiness you are noticing is actually caused by tiny air bubbles. To test this theory, pour a glass of filtered water and let it sit. The "milky" bubbles should disappear from the bottom of the glass up, much like the carbonation in soda. This cloudy appearance should cease in one to two weeks with regular use.
This "rotten egg" smell is actually caused by harmless bacteria which produce hydrogen sulfide gas. If your water only smells bad after it has exited the filter, then these bacteria have most likely built up within the filter housing itself. You will need to sanitize the filter housing (see question 3 for instructions on how to sanitize your system). This process will disinfect the housing and the water line, but will not remove sulfur bacteria in the water entering your home. If problems persist, call your local water conditioning dealer.
If you are using a cellulose paper filter cartridge (such as the TrueFog, USA' S1 cartridges), you may want to replace it with a synthetic filter cartridge (such as the P5 or CW-F cartridges). Cellulose filter cartridges are not resistant to bacteria, and should not be used with water that is inadequately chlorinated.
3. How do I sanitize my
filter?
To sanitize your filter, remove the filter cartridge from the plastic housing and add 1 cup of bleach in the bottom of the housing. Screw the housing back on to the cap and turn on the system. When you can smell bleach in the water coming out of the nozzles, turn off the system. Let bleach solution sit in the housing and water lines for ½ hour, then turn on the system to flush thoroughly .
If the O-ring that creates the seal between the cap and the top of the housing is dirty or seated improperly in the O-ring groove, then the filter housing may leak. Unscrew the bottom of the housing and remove the O-ring. Clean the o-ring to remove grit and examine for kinks, cuts, or deterioration. In addition, wipe out the O-ring groove located at the base of the threads of the filter housing. Then lubricate the O-ring with silicon gel replace it in the housing, making sure it is seated properly in its groove. Screw the bottom of the housing securely back onto the cap. If the unit still leaks, you may need to replace the O-ring.

Probably not. First, check to make sure your water supply has been turned on and that the cartridge is installed correctly. Certain TrueFog, USA filter cartridges must be installed in the housing facing a certain direction in order to work properly. Consult your user’s manual or the cartridge insert sheet for specific instructions. Also, make sure the cartridge is seated properly over the standpipe in the bottom of the housing (if present).
7. I have a
TrueFog, USA filter and the diverter won’t
shut off. Do I need a new diverter?
It is most likely that some scale has built up inside the diverter. Remove the diverter from the faucet and soak it overnight in vinegar. This should dissolve the scale that is causing it to stick.
