    High Pressure Quick Connect fittings that can be used on either 1/4" od  copper or plastic tubing

  • Does it remove pharmaceuticals?

    Carbon filters do remove some pharmaceuticals from drinking water but I cannot guarantee how much or what ones. The best filter would be a reverse osmosis system as they remove pretty much everything.
