Advanced Three-Stage Filtration with the Doulton Ultracarb® Cartridge

The Doulton Ultracarb® cartridge utilizes a unique triple filtration process for comprehensive water purification:

Stage 1 – Outer Ceramic Shell: Manufactured from Sterasyl® ceramic material that provides sub-micron filtration, removing fine particulates, bacteria, cysts, and turbidity. Silver within the ceramic shell inhibits microbial growth.

Stage 2 – Inner Carbon Block Core: Contains high-grade, NSF-certified coconut shell activated carbon that adsorbs chlorine, organic compounds, and improves taste/odor. Extensively tested to NSF protocols.

Stage 3 – Ion Exchange Resin: Further reduces dissolved heavy metals including lead.

By combining mechanical filtration, adsorption, and ion exchange into one integrated cartridge, the Ultracarb® delivers robust, multi-faceted water purification. Its proprietary Sterasyl® ceramic shell coupled with premium coconut shell carbon block ensure optimal filtration performance. It also effectively reduces PFOA and PFOS to below the stringent NSF 53 safety limit with results backed by an independent laboratory  (see test report here).

The Doulton Ultracarb® water filter’s versatile design allows it to improve water quality from various sources:

• Rainwater tanks
• Rivers or lakes
• Well or bore water
• Municipal tap water
