Nobana Replacement A8 PCT

Replacement compound pre-filter (PCT) cartridge for the NOBANA A8 tankless reverse osmosis system. This is the first of the two cartridges in the A8 — it strips sediment, chlorine, VOCs and odours before water reaches the RO membrane, so changing it on schedule is what keeps the more expensive membrane alive.

Key specs

• 5 μm sediment + activated carbon + carbon block in a single integrated cartridge
• Removes sediment, particulate, suspended solids, chlorine, VOCs, limescale and odours
• Tool-free 3-second swap — twist out, twist in
• Replace every 9–12 months
• Compatible with all A8-600 and A8-800 systems
• 6-month warranty

Why we sell it — the A8 advertises 3-second filter changes for a reason: the cartridge is designed to be replaced regularly without calling a technician. Skip a PCT change and you'll burn out the integrated RO module 6-12 months early — much more expensive than a fresh PCT. We hold A8 PCT cartridges at Sannat in stock.
