The ceramic of a filter candle is cast in such a way that it has one domed closed end. The other end of the ceramic is open. This open end is closed off with a food grade plastic mount, which enables the candle to fit into a filter housing. Water passes from the outside of the candle to the inside, leaving particles of dirt, bacteria, etc. on the outside of the ceramic. The filtered water then passes out of the candle through the mount. |
| There are 2 standard types of mount (long and short). The length of mount required is determined by the type of housing into which it is to be fitted. |
 |
The short mount is ¾ inch or 19mm long. |
 |
The long mount is 1 ¼ inch or 36mm long. |
Both long and short terminate in a ¼ inch BSP male thread.
All FICL candles are available in three standard lengths:
 |
5 inches (127mm) |
 |
7 inches (178mm) |
 |
10 inches (254mm) |
Bespoke lengths and/or mounts might be possible for significant quantities. Please contact the FICL sales department with any specific requests. |

A filter cartridge is a ceramic tube, which is cast open at both ends (OBE). Both ends are then closed off with food grade plastic mounts, which enable the cartridge to fit into a filter housing. The mount at the base of the tube is completely closed. The mount at the top of the tube has an opening through which filtered water flows after it has passed through the ceramic. Particles of dirt, bacteria etc. are trapped on the outside of the cartridge. |

Cartridges are available as standard in two sizes - Slimline and Imperial. Bespoke lengths and or mounts might be possible for significant quantities. Please contact the FICL sales department with any specific requests. |

At the heart of all FICL’s filters is the Sterasyl™ ceramic. The ceramic is impregnated with silver to make it self-sterilising. Silver inhibits the growth of bacteria. Sterasyl™ ceramics have a tightly controlled complex pore structure, which has unparalleled filtration properties. Sterasyl™ is effective in both gravity and pressure filters.
Benefits:
With its Absolute filtration rating (defined as >99.99%) of 0.9 microns, Sterasyl™ is highly effective against particulate contamination, pathogenic bacteria, cysts etc. |

The Sterasyl™ ceramic is filled with granular activated carbon to produce the Super Sterasyl™ filter element. Among other things, activated carbon is very effective at removing chlorine and organics from water.
Super Sterasyl™ uses granular activated carbon instead of an activated carbon block in order to give superior flow rates in a gravity filter. Granular carbon is not as effective as a carbon block under pressure conditions. Therefore, in a pressure filter, Supercarb™ should be used for chlorine and organics removal.
Benefits:
Super Sterasyl™ has all the benefits of Sterasyl™ (removal of particles, pathogenic bacteria, cysts etc.), with additional chlorine and organics removal capabilities. |

The Sterasyl™ ceramic is filled with granular activated carbon and an ion exchange resin to produce the ATC Super Sterasyl™ filter element. Among other things, activated carbon is very effective at removing chlorine and organics from water, while the ion exchange resin removes heavy metals, in particular lead.
Super Sterasyl™ uses granular activated carbon instead of an activated carbon block in order to give superior flow rates in a gravity filter. Granular carbon is not as effective as a carbon block under pressure conditions. Therefore, in a pressure filter, Ultracarb™ should be used for chlorine, organics, and lead removal.
ATC Super Sterasyl™ has all the benefits of Sterasyl™ (removal of particles, pathogenic bacteria, cysts etc.), with additional chlorine, organics and lead removal capabilities. |

The Sterasyl™ ceramic is fitted with an activated carbon block insert to produce the Supercarb™ filter element. Among other things, activated carbon is very effective at removing chlorine and organics from water. Supercarb™ is designed to be used in pressure filters (on a mains water supply), not in gravity filters.
Benefits:
Supercarb™ has all the benefits of Sterasyl™ (removal of particles, pathogenic bacteria, cysts etc.) with additional chlorine and organics removal capabilities. |

The ceramic shell is fitted with both an activated carbon block and an ion exchange resin inset to produce the Ultracarb™ NSF. Among other things, activated carbon is very effective at removing taste and odour from water. The ion exhange resin specifically removes lead from water. Ultracarb™ NSF is designed to be used in pressure filters (on a mains water supply), not in gravity filters.
Benefits:
The Ultracarb™ NSF removes taste and odour, particulate, turbidity and cysts. |
