Stage 1 - Fluoride

This filter cartridge reduces the fluoride in drinking water and is usually placed as the first of the two cartridges in the Doulton Duo system. This filter can also be used in gravity filter systems or hip housings.

The filter elements are designed to reduce fluorides in drinking water to below 0.5 ppm

Fluoride cartridge life - 3 months typical usage before cartridge replacement is required

Stage 2 - Ultracarb

Multistage filtration in one filter cartridge:
Stage I - Outer Shell-Micro Filtration
Stage II - Anti-Bacterial formula within the ceramic matrix inhibits microbial growth
Stage III - Activated carbon in the Ultracarb candle takes out chlorine and organics improving taste and odour
Stage IV - Ultracarb also contains heavy metal removal media, which takes out toxic lead Ultracarb filter candle life - 6 months* before replacement of the ceramic filter is required. *Cartridge and filter candle life may vary depending on your local water conditions.
