Royal Doulton Ultra Sterasyl Gravity Water Filter Candle

Upgrade your water filtration with the new and improved Ultra Sterasyl® filter from Doulton/Berkefeld – precision-engineered in Great Britain for unmatched performance and reliability.

Designed with multi-stage protection, this premium ceramic filter delivers safe, clean, and great-tasting drinking water by tackling a wide range of modern contaminants:

The Ultra Sterasyl® provides a superior barrier against bacteria, parasites, and particulate matter—without the need for boiling or sterilisation.

How it works – 4 Stages of Filtration:

• Ceramic outer shell traps bacteria, cysts, and particles.
• Silver-infused ceramic – inhibits microbiological growth inside the filter.
• Activated carbon core– reduces chlorine, organics, and improves taste and odour.
• Heavy metal reduction media – targets toxic lead and PFAS chemicals.

Built to last and safe for your family:

Long-life capacity: up to 1500 litres (6–9 months, depending on water quality).

Flow rate under gravity: 700–900 mL per hour
Made from durable, food-grade, BPA-free materials.

Independently NSF certified for quality and safety.
Manufactured in the UK using advanced ceramic techniques.
Important notes:

Does not remove fluoride (separate fluoride filters available).

Pre-soak overnight before installation, and flush with 2–4 litres of water before first use to clear harmless carbon fines.
The Ultra Sterasyl® is the premium replacement cartridge for your British Berkefeld® or compatible gravity filter system—delivering clean, refreshing water with peace of mind.
