Omnipure - E5721-P - 14" x 2.5" E-Series 10 Micron Carbon Block, Phosphate Filter - Scale Inhibitor

The Omnipure E5721-P combines 10 micron carbon block filtration with polyphosphate scale inhibition in a single 14" x 2.5" inline cartridge. This E-Series filter reduces chlorine taste and odor while actively preventing scale buildup in downstream equipment and plumbing.
SPECIFICATIONS

Omnipure E5721-P Technical Details

Model Number Omnipure E5721-P
Dimensions 14" length x 2.5" diameter
Micron Rating 10 micron
Filtration Media Carbon block with polyphosphate
Flow Rate 0.5 GPM maximum
Service Life 1 year or 3,000 gallons
Operating Pressure 125 PSI maximum
Temperature Range 33°F to 100°F
INSTALLATION & USE

Filter Replacement Procedure

  1. Shut off water supply and relieve system pressure by opening a downstream faucet
  2. Remove old cartridge by turning counterclockwise from the existing filter head
  3. Install the Omnipure E5721-P by threading clockwise into the universal cap head until hand-tight
  4. Turn water supply back on slowly and check for leaks at the connection points
  5. Flush the new carbon block filter for 5 minutes before use to remove carbon fines
COMPATIBILITY

System Requirements

The E5721-P features Omnipure's universal cap design that fits all permanent E-Series filter heads. This 14 inch cartridge is commonly used in ice machines, beverage equipment, coffee makers, and as a post-filter in reverse osmosis systems where both chlorine reduction and scale prevention are needed. The polyphosphate media sequesters calcium and magnesium to prevent hard water scale formation without removing beneficial minerals.

🔧 Pro Tip: Replace this filter annually even if you haven't reached the 3,000 gallon capacity. The polyphosphate scale inhibitor depletes over time regardless of water volume, and older carbon becomes less effective at chlorine reduction.
