GE SmartWater Replacement Reverse Osmosis Filters (FX12P)

How long the filters last depends greatly on your individual water supply. I've sinced pulled the battery out of the faucet because it is just a timer and has nothing to do with actually meaning the filters are dirty. I'm averaging about 9 month on the Pre and Post Filters instead of recommended 3 month. When I change them the prefilter is usually reddish (rusty looking) and the post filter just grayish. I've had the Osmosis filter in place now for about 4 years. I test the water with a TSD meter (Total Disolved Solids) and testing water out of the regular faucet it reads around a 10, Testing water out of the Osmosis filter it tests a zero.

These are the two filters which, along with the reverse-osmosis membrane (the real heart of the system) make up the GE reverse-osmosis system.

I had no trouble, but I have a bit of mechanical ability. I know some people who, frankly, have trouble with changing a light bulb. This replacement might be discouraging if you are in that category. But if you are, take heart! Don't give up on yourself. You can always learn, and practice at simple mechanical things is a valuable learning activity, as good for the brain as an "intellectual" activity -- and so say I.

We were somewhat apprensive that the filters would be good quality; however, they were and will likely re-order when needed.
