I have a Brita faucet filter (model FF-100) that lately has become harder and harder to turn. I toyed with the idea of forcing the unit apart but, instead opted to lube the mechanism directly from the top, where the unit attaches to the faucet.
To this mean, you will have to 1) Detach the unit from the faucet. 2) Remove the filter. 3) Thoroughly wash the unit, inside and out, turning the knob to flush any debris that may be present. 4) Pour some drops of vegetable oil inside the mounting opening, coating the valve stem within. (Oil may pass thru the unfiltered water outlet, so choose an appropriate working space). 5) Turn the water handle (knob) to lube the valve repeatedly, until it loosens. 5.b) Optionally, you could let the oil sit for some time inside the base. 6) Rinse the unit and reinstall it on faucet (without the filter). 7) Turn knob to unfiltered position, and flush with warm/hot water. 8) Do likewise with knob set to filtered, but open faucet only slightly, to avoid over-spraying. 9) Remove base unit from faucet and repeat steps 3-9, as needed. 10) Reinstall unit with filter, as instructed by manual.
Water valves may seize due to mineral deposits. While you may be tempted to use detergents or solvents, be reminded that unless thoroughly rinsed, chemicals may corrode plastics, degrade your filter, or even wind up in your drinking water, so caveat.

Was anyone respond to you? I have a same problem !
I fixed the problem by cutting a slit in a synthetic wine cork and shoving it onto the knob. Works great now that I can get a grip on it. But you know, we shouldn\'t have to do this, the knob should be engineered to function.
We had the same problem, and eventually the knob broke off leaving us leaving it unusable. We bought a new system, and again, the knob is getting harder to turn. We took it off of the faucet to see if we could clean around the knob but there is no way to do that. This is definitely a manufacturing defect!
