  • Omnipure Q5685 Q-Series Water Filter:
  • The Omnipure Q5685 is a water filter with phosphate scale inhibitor.
  • The Omnipure Q5685 Scale Inhibitor water filter is very "user friendly".
  • Replacement of the spent media bed is done quickly by detaching the filter body from a permanent head with a twist of the wrist.
  • The new Q5685 filter body is just as easily threaded into the head and the replacement is then complete.
  • The Omnipure Q5685 is also available with the optional Twist Tap in-head valve system, which automatically turns the supply water off when the body is disconnected from the head.
  • The Omnipure Q5685 filter is used to prevent scale deposits and precipitation for applications including Ice Machines, Coffee Makers, Distillers, Hot Water Heaters, Evaporators & Steam Generators.
  • The Omnipure Q5685 is a crystalline polyphosphate (slow dissolving) filter with 20 micron polyspun postfilter.
We do not stock the Q5685 filter. Email customerservice@waterfilters.net or call 1-888-801-7873 if you would like to special order the Q5685. An alternative option is the Q5620-P filter. This filter fits exactly the same but has additional contaminant reduction. Another alternative is the Q5786 filter. This filter is 14" long and has additional contaminant reduction. The Q5786 filter will fit in the filter head used by the Q5685.

  • Omnipure Q5685 Q-Series Water Filter Instructions:
  • Omnipure Q5685 water filters should be installed on cold water lines only.
  • Omnipure Q5685 water filters should not be used where the water is microbiologically unsafe.
  • Omnipure Q-Series Head O-Ring Instructions:
  • Each time you change your filter, clean and apply silicone, food grade lubricant, OR-LUBRICANT-LG or OR-LUBRICANT-SM, generously to both the small and large o-ring in the Q-Series Head.
  • It is recommended that you replace the Omnipure H-118 O-Ring, every time you change your filter. The H-118 O-Ring is the larger of the two o-rings in the Q-Series Head System. If you do not replace the H-118 O-Ring, you may experience leaking because the o-ring adjusts to the shape of the old filter, which may be slightly different than the new filter.
  • The Omnipure H-011 O-Ring is the smaller o-ring in the Q-Series Head. Inspect this o-ring for any signs of damage, and replace as needed.
