We drink bottled water, so I replaced that fixture early on with a soap dispenser. I found it not to be of the highest quality and would probably have had to be replaced in the long run. I realize this doesn't answer your question it does give you another option...
Due to hard water, we are required to disassemble our home unit every couple of years. Clean it with Lime-A Way and it's good for another 3-4 years. We added one to a trailer and found the entire upper unit for about $10. on ebay (new). Seems they are mid $20's @ Lowes/Home Depot.

Does the filtered outlet drip all of the time? I find that mine drips when the water heater is warming up. Could be the the check valve at the water heater is allowing a pressure build up.
On mine I just ignore it as it won't be long before the hot water is used and the drip stops.

My original unit had the valve handle that twisted. It began dripping, and per advice on this board I called Everpure and they sent me a replacement free. The new faucet has the lever style valve handle.
