NOBANA REPLACEMENT S7 Pro Compound Pre-Filter (for 400GPD Systems)

Replacement 3-in-1 compound pre-filter cartridge for the NOBANA S7 Pro 400 GPD tankless RO system. Combines sediment, granular activated carbon and carbon block in a single standard 2.5 × 10 inch housing — three filter stages in one swap.

Key specs

• 3-stage cartridge: 5 μm sediment + carbon + carbon block
• Removes sediment, chlorine, odours and off-tastes before the RO membrane
• Standard 2.5 × 10 inch format — fast tool-free swap
• Replace every 12 months
• 6-month warranty

Why we sell it — the S7 Pro relies on the pre-filter doing its job to keep the integrated RO+carbon cartridge clean. Skip a CBPA change and you'll burn out the more expensive RO module early. We keep S7 Pro pre-filters in stock at Sannat.
