Water Pitcher & Dispenser Filter Screen is selected when an assembly or process calls for retaining carbon granules and ion-exchange resin inside water pitcher cartridges and protecting dispenser taps from particles. This application guide to the NSF/ANSI 42 / 53 assemblies type covers concrete end-uses, the specification checklist, correct installation, and where an alternative mesh or filter medium performs better.
Typical Applications for Water Pitcher & Dispenser Filter Screen
Where Water Pitcher & Dispenser Filter Screen is specified and bought:
- Water filter brands: screens above and below carbon/resin beds.
- Dispenser & cooler OEMs: tap-inlet screens.
