Doulton Super Sterasyl Filter Candle 5 inch x 2.75 Inch
Royal Doulton’s Super Sterasyl filter has a lifetime of 12 months or 2000 litres, making it one of the most long-lasting gravity filters available. Scrub clean under running water for extended filter life. This filter employs a multi-stage filtration system to provide water purification through several mechanisms:
- Particulate filtration down to 0.9 microns catches particles, sediment, and turbidity. This high level of filtration ensures the removal of particulate contamination.
- Absolute filtration rating of 99.99% at 0.9 microns and nominal filtration rating of 99.9% at 0.5 micron helps reduce harmful bacteria and protozoan cysts like giardia and cryptosporidium.
- Activated carbon filtration stage aids in reducing chlorine and certain organic contaminants.
- Silver impregnation integrated into the ceramic walls provides enhanced defence against against microbiological growth
- Suitable for our British Berkefeld Water Filter.
The Super Sterasyl has undergone testing based on standards from the World Health Organization as well as national laboratories in over 50 countries. While no single water filter can remove every potential contaminant, Royal Doulton’s Super Sterasyl filter provides multiple barriers and mechanisms for significantly improving water quality and safety. Customers can have confidence that this gravity filter system can deliver reliably clean, filtered water for a range of applications.

Description
Understanding Filter Ratings: Absolute vs. Nominal Explained
“Absolute” and “Nominal” refer to different ways of stating the filter’s pore size and efficiency:
Absolute Rating:
– The absolute rating specifies the largest particle size that the filter will allow to pass through 100% of the time.
– For a 0.9 micron absolute rating, this means the filter will remove 100% of particles larger than 0.9 microns.
– No particles larger than the absolute pore size rating can pass through the filter.
Nominal Rating:
– The nominal rating refers to the approximate particle size that the filter can remove with a specified efficiency, usually 85% or higher.
– For a 0.5 micron nominal efficiency of 99.9%, it means the filter removes 99.9% of particles 0.5 microns and larger.
– However, some particles larger than 0.5 microns may still pass through the filter, unlike the absolute rating.
The absolute rating guarantees 100% removal of particles above that size. The nominal rating indicates the approximate size removed at a high but not 100% efficiency.
The 0.9 micron absolute and 0.5 micron 99.9% nominal ratings show the Sterasyl filter has very high particle and microorganism removal capabilities down to the 0.5 micron range.
