Cuno P165BN Replacement Cartridge

Cuno (Aqua-Pure) P165BN Replacement Cartridge 56156-01

The Aqua-Pure® Model P165BN espresso water-filtration
cartridge assures consistent high-quality water for espresso and
espresso-based drinks at flow rates to 1.0 gpm (3.8 lpm). A blend of
high-capacity strong and weak-acid ion-exchange resins reduces calcium
and magnesium ions to prevent hard scale formation on the heating coils
and boilers that results in energy inefficiency, downtime, and expensive
service calls. Inlet water TDS and alkalinity are also reduced. Premium
activated carbon reduces chlorine taste and odor and bitterness
associated with poor water quality. A built-in bypass directs 75% of the
inlet water through the media combination for treatment. Model
P165BN has a capacity of 719 gallons (2,722 liters) for inlet water
with 150 ppm (9 gpg) hardness.


  • Consistent great tasting espresso and espresso drinks from water with reduced hardness,
    alkalinity, TDS and chlorine taste and odor.
  • Increased lifetime and capacity from a built-in bypass that allows 25% of inlet water
    to pass through untreated.
  • NSF and/or FDA CFR-21 compliant materials.
  • Reduced hard scale formation on the heating coils by the reduction of calcium and
    magnesium ions results in improved energy effi ciency and reduced downtime and
    expensive service calls.
  • Valve-in-head design simultaneously shuts off and vents water, allowing for simple
    and virtually trouble-free cartridge change-outs without the need to shut off the
    upstream feed water.
  • Sanitary Quick Change (SQC) encapsulated cartridge design allows for fast and easy
    cartridge change-outs with a 1/4 turn.
  • 3/8" FNPT horizontal inlet and outlet ports allow direct or easily adaptable connections
    to existing plumbing lines.
  • Optional pressure gauge allows monitoring of downstream water pressure.

CUNO Incorporated recommends regularly scheduled maintenance and
replacement of the filter cartridge(s) in order for the product to perform
as advertised/sold. Change the filter cartridge at least every 6 months.
CUNO shall not be liable for system failures due to improper maintenance.
