Product review (5 stars): Turn the water supply OFF before changing
I don't know where I got the notion that you don't have to turn off the water supply before you change the filter on a GE refrigerator. My previous refrigerator was a Whirlpool Gold and I could change filters without turning off the water supply. Don't try this with a GE refrigerator unless you want to spend a long time cleaning up spilled water, depending on where the shut off is located. Having said that, the filter works great. We live on a mountain top with a deep well that provides crystal clear water without treatment. However, I have a whole house filter, mainly to remove occasional grains of sand that tend to clog the washing machine inlets. The GE filter is the last line of defense and provides us with drinking water that is extremely pure. I much prefer our water to any bottled water I have tasted, including the very pricy French stuff. It is an expensive filter, but so was the filter on our old Whirlpool. At any price, it works great and insures a pure water supply to the family.

I had a very alarming wake up call when I started to reorder this filter and noticed that the price jumped to $42.99.  I live on a mountain top and my deep well provides very pure water, along with a whole house filter to remove and prevent sand particles from clogging the washing machine hoses. Also, after reading some of the other reviews, it seemed that this filter does not do much except take money out of your pocket. Instead of the filter, I ordered the" GE WR02X11705 Cap Filter Bypass for Refrigerator"  ( $15.90 at Amazon) and (after turning off the water supply) installed it in place of the filter. My honest opinion is that, in my case, I could not detect one bit of difference in the water taste. As a bonus, the water flow rate increased. I will not downgrade this filter because every case is going to be different, depending on the quality of the water coming into your home. However, if you already have a whole house filter, the GE filter at $42.99 won't buy you very much.
