Omnipure - E5621-P - 12" x 2.5" E-Series 1 Micron Carbon Block, Phosphate Filter - Scale Inhibitor
E5621-P Carbon Block Water Filter with Phosphate Scale Inhibitor
The Omnipure E5621-P combines fine 1 micron carbon block filtration with polyphosphate scale inhibition in a single inline cartridge. Engineered for applications where both sediment reduction and scale prevention are critical, this filter delivers 0.5 GPM flow rate while treating up to 2500 gallons or one year of service life.
Dual-Action Filtration and Scale Prevention
1 Micron Carbon Block
Fine carbon block media reduces chlorine, taste, odor, and sediment down to 1 micron for clean, fresh-tasting water
Polyphosphate Scale Inhibitor
Integrated phosphate media prevents scale buildup and corrosion in plumbing, fixtures, and downstream equipment
Universal Cap Design
Proprietary cap fits all existing permanent Omnipure filter heads for tool-free installation and replacement
2500 Gallon Capacity
Rated for 2500 gallons or 1 year of service life at 0.5 GPM flow rate, 125 PSI max pressure, 100°F max temperature
