Two-Stage Filtration Designed for Tank Water

Stage 1: 5 Micron Washable Tank Water Pre-Filter

The first stage uses a Tank Water Pre-Filter Washable Cartridge to help capture sediment, sand, dirt and rust commonly found in tank water supplies.

Its pleated polyester design maximises dirt-holding capacity and is resistant to bacteria and chemicals, helping protect the second-stage cartridge and maintain optimal filtration performance.

Stage 2: Doulton Ultracarb Ceramic Cartridge

The second stage features the premium Doulton Ultracarb Cartridge, combining ceramic filtration with activated carbon technology.

The Doulton Ultracarb is formulation tested to remove 99.99% of bacteria, parasites and particles, including potentially harmful organisms such as Giardia, Cryptosporidium and E. coli.*

Its ceramic outer surface can be gently cleaned during its 12-month service life to help restore water flow and extend cartridge performance. See our DIY Maintenance Guide.
