Orders that ship directly from a manufacturer normally have a firm shipping estimate but those dates are subject to change due to manufacturer production, inventory or shipping. We do our best to estimate ship dates but orders shipping directly from the manufacturer can have unexpected delays. We will confirm tracking information when orders ship directly from a manufacturer but may not have updates or estimates beyond the original estimate. Once your order is placed with the manufacturer, it may not be able to be cancelled even if it hasn't shipped yet.

Please note that shipping rates are subject to change at any time. We reserve the right to charge an additional fee in addition to the regularly advertised shipping fee for shipping to remote areas not easily accessible by typical freight carrier means (i.e. islands only accessible by ferry).

Please note, these instances are very rare, as most locations are reachable by regular freight. If you have any questions, please contact us!

FAQ
Q: How often should I replace my CLARIS L filter cartridge?
A: The Pentair Everpure EV433912 CLARIS L cartridge should be replaced when you reach its capacity (1,100 gallons for espresso or 1,255 gallons for coffee) or every 6-12 months, whichever comes first, to ensure optimal performance.

A: The CLARIS L cartridge is designed for commercial specialty coffee, tea, and steam applications. Check your equipment specifications or contact the manufacturer to confirm compatibility with your specific system.
Q: How does the CLARIS L filter improve coffee quality?
A: The CLARIS L filter uses DUOBLEND technology to control carbonate hardness and reduce limescale, while also filtering chlorine taste and odor. This creates optimal water conditions that enhance flavor extraction and protect equipment from scale buildup.
Features & Benefits:
- DUOBLEND Technology: Provides precise control of carbonate hardness levels, allowing you to tailor water hardness to match your desired flavor profile.
- Equipment Protection: Reduces limescale buildup and corrosion, extending the life of expensive coffee and espresso equipment.
- Enhanced Beverage Quality: Filters chlorine taste and odor while maintaining beneficial minerals for optimal extraction and flavor.
- Easy Maintenance: Quick-change cartridge design allows for simple replacement without specialized tools or extensive downtime.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.
