Quote from Nwfdrool :
How is this better than the water filter built into the fridge?
RO systems remove quite a bit more impurities... however, they also remove minerals in the water that you would want. It depends on your water source if it is the right choice for you. If your water supply has high arsenic (almost all city water supplies do), lead etc then I would recommend one.

Beyond this, If you do not need one, I would recommend searching for an external mount filter for your fridge. I have an RO system but it is mounted in an island without a way to supply the water to my fridge. For my fridge I buy a 2 year filter ( I still change it once per year) that mounts on the wall behind the fridge. It works way better than the internal filters do and lasts significantly longer. If you go this route, you need to remove the filter inside the fridge. You should just be able to remove it. Water will still go to your dispenser without it installed. I use this one: https://www.waterdropfilter.com/p...ion-system but with this filter https://www.waterdropfilter.com/p...8595231826 Amazon sells it.
