HF20BB-RC20BB - 20in Large Diameter Housing with Refillable Cartridge (Supplied Empty)

High Flow Organic Colour Removal Filter Housing

The HF20BB-RC20BB 20" Large Diameter Housing with Refillable Cartridge is a versatile, high-flow filtration solution designed for organic colour removal, tannin reduction and taste improvement in private water supplies and commercial systems.

Supplied empty, this system allows you to choose the most suitable carbon media for your application — making it ideal for boreholes, wells, surface water, and properties affected by yellow, brown or tea-stained water.

💧 Why Choose This System?

Organic colour in water is commonly caused by natural tannins and decaying vegetation. Filtering through granular activated carbon is one of the most effective and proven treatment methods.

All carbon media can remove colour — however:

• Natural Bone Charcoal – Considered the most effective media for colour removal, especially where shorter contact time is required.

• 207C Coconut Shell Carbon – Ideal for milder discolouration and general taste & odour improvement.

The refillable cartridge design allows flexibility and cost-effective media replacement.
