@coffcoff Well...it is not a manufactured setup per se. We use a generic 2 stage filter housing from a big box store, mounted just below the generic "filtered water" kitchen tap in our sink. In that filter housing we place a high-quality carbon filter in the first position (where the water enters) and a dental-grade .2 micron filter in the second position (where the water flows to the tap.) It is attached so that a very short vertical piece of tubing attaches to the faucet, this eliminates the concern of water standing in the hose. I think the current filters are from Blu Technology, but could be from NanoCeram or a dental supplier, I'm not certain.

We replace these every 3 months, or if the flow slows down.
