British Berkefeld 7″ Ultra Sterasyl Ceramic Water Filters (Set of 2)

The British Berkefeld 7-inch Ultra Sterasyl ceramic filters deliver powerful multi-stage filtration designed specifically for gravity water filtration systems.

Each filter features a micro-porous ceramic outer shell that physically blocks bacteria, cysts, and sediment. Inside the filter, activated carbon filtration media helps reduce chlorine, organic chemicals, and other contaminants while improving the taste and clarity of drinking water.

Ultra Sterasyl filters are certified by NSF International to four drinking water standards, verifying their performance through rigorous third-party testing.

This set of two filters provides reliable ceramic filtration for everyday drinking water while maintaining a simple gravity-powered design that requires no electricity or plumbing.

Ultra Sterasyl filters are widely used for home kitchens, emergency preparedness, off-grid living, camping, and everyday drinking water filtration.

NSF Certified Filtration

British Berkefeld Ultra Sterasyl filters are certified by NSF International to four drinking water standards, confirming their performance for contaminant reduction and material safety.

✔ NSF/ANSI Standard 42 – Reduction of chlorine, taste, and odor
✔ NSF/ANSI Standard 53 – Certified for health effects contaminant reduction such as lead
✔ NSF/ANSI Standard 372 – Certified lead-free materials
✔ NSF/ANSI Standard 401 – Reduction of emerging contaminants

These certifications confirm that the filters meet strict third-party testing standards for drinking water safety and filtration performance.

Key Benefits

✔ Helps remove bacteria, cysts, and sediment
✔ Reduces chlorine and organic chemicals
✔ Improves taste and odor of drinking water
✔ Helps reduce lead and heavy metals
✔ Helps reduce microplastics and turbidity
✔ Gravity powered – no electricity required
✔ Cleanable ceramic shell helps extend filter life
✔ Helps retain beneficial minerals naturally found in water

Contaminant Reduction

Ceramic gravity filters combine mechanical ceramic filtration with activated carbon, helping reduce bacteria, sediment, chlorine, heavy metals, and other contaminants from drinking water.

Specifications

Installation: Upper chamber of gravity filtration systems

Each filter includes the wing nut and washer required for installation.

Filter Life

Each Ultra Sterasyl ceramic filter can treat approximately 800 gallons of water before replacement is recommended.

A set of two filters can treat up to 1,600 gallons, typically lasting 6–12 months depending on water quality and usage.

The ceramic outer shell can also be cleaned periodically to help maintain filtration performance.

Designed for British Berkefeld Gravity Systems

The Ultra Sterasyl ceramic filter is specifically designed for British Berkefeld gravity filtration systems.

The ceramic outer shell provides mechanical filtration that physically blocks bacteria and sediment, while the internal activated carbon helps improve taste and reduce chlorine and organic compounds.

This combination creates a reliable gravity filtration system that works without electricity or plumbing.

System Compatibility

The number of filters used depends on the gravity system size.

Using multiple filters increases filtration speed and total system capacity.

Gravity Water Filter Comparison

Many gravity filtration systems appear similar but use different filtration technologies.

Ceramic filtration remains popular because the micro-porous ceramic shell physically blocks bacteria and sediment, while carbon media improves taste and reduces chemicals.
