Years ago we had an "Everpure PBS-400". It was designed for "sinks and wet bars." I put it on our kitchen sink (cold side only). It did reduce the flow rate a little, but still plenty to be useable. We had city water, but didn't like it.
They don't appear to make the PBS-400 any more, but they still make filters for it.
I suspect this is the new version of the same thing (under sink filter). The filter is rated for 3000 gallons or 1 year. This is designed for 2.2gal/min flow rate.

They have a commercial thing that looks more like what we had and is designed for "fountains". It's designed for a 1.67gpm flow rate, so quite a bit less than the one above. I assume it may filter a bit more, but be more irritating when you're trying to fill a huge pot with water or wash dishes. It's rated for 9,000 gallons.
