20" Big Blue Carbon Block Filter Cartridge

Replacement 20" Big Blue carbon block cartridge that reduces chlorine, bad taste, odour and fine sediment from your whole-house or under-counter system. Choose the carbon loading that suits your water quality and budget — the higher the mg/g rating, the greater the adsorption capacity.

Recommended replacement every 12 months or 3,500 L, depending on your water quality. Fits all standard 20" Big Blue housings.
