  • Omnipure Q5421 Q-Series Carbon Block Water Filter:
  • The Omnipure Q5421 Block GAC 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 Q5421 filter body is just as easily threaded into the head and the replacement is then complete.
  • The Omnipure Q5421 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 Q5421 Water Filter can be used in ice makers, refrigerators, beverage equipment, drinking fountains, under the sink systems, and reverse osmosis systems.
  • The Omnipure Q5421 GAC water filter is a 10 micron block granular activated carbon filter used to reduce taste, odor and chlorine taste and odor.
We do not stock the Q5421 filter. Email customerservice@waterfilters.net or call 1-888-801-7873 if you would like to special order the Q5421. An alternative option is the Q5621 filter below. This is a 12" version of the Q5421 filter which means it will last longer. The Q5621 has the same contaminant reduction as the Q5421. If you need an 8" filter, the Q5486 filter below is stocked and contains GAC and phosphate, but does not reduce down to 10 microns like the Q5421. Both of these alternatives will fit in the filter head used by the Q5421.

  • Omnipure Q5421 Water Filters are designed to fit:

  • If you do not have a head for the Omnipure Q-Series filters, you can purchase one of the Omnipure Q-Series heads below in the Related Products section. These heads are valved which means the water will automatically shut off when replacing the Q-Series water filter. The heads are available with 1/4" quick connect fittings, 1/4" NPT, or 3/8" NPT.
  • Omnipure Q5421 Q-Series Water Filter Instructions:
  • Omnipure Q5421 water filters should be installed on cold water lines only.
  • Omnipure Q5421 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.
