Compatibility

• Cartridge size: 20" x 4.5"

• Not the replacement set for Aquarius Fluoride/PFAS or standard Aquarius anti-scale configurations.

Replacement guidance

A typical service interval is approximately 12–18 months, but actual cartridge life depends on incoming water quality, usage, flow and contaminant loading. Replace earlier if flow or water quality indicates the filters are exhausted.

System reference specifications

• Nominal cartridge format: 20" x 4.5"
• Three replacement stages
• Whole-system flow reference: up to approximately 50 L/min under suitable conditions

Important: Filtration performance depends on the exact cartridge, source-water chemistry and operating conditions. Certification or testing of an individual component should not be interpreted as certification of the complete installed system unless expressly stated.
