The Doulton Imperial Ultracarb is an excellent filter and its ability to remove such a wide variety of metals, chemicals, cysts and bacteria make it superior to most other filters on the market today.

The Ultracarb features a ceramic outer casing with an activated carbon block inside to provide both excellent protection from bacteria and cysts etc and treatment of chemicals and lead. The ceramic is impregnated with silver to make it self-sterilising as silver inhibits the growth of bacteria. The activated carbon is particularly good for removing chlorine and organics and there is also an ion exchange resin insert for treatment of lead and heavy metals.

This cartridge is ideal for tank water because of its ability to remove bacteria and cysts and its silver content means it won’t breed bacteria like a standard carbon cartridge normally would in a tank water situation. All tank water has some level of bacteria.

The micron rating on this filter is 0.9 Micron Absolute. The manufacturers of this product provide an Absolute rating as opposed to a Nominal rating which is more common. If this product was rated with a nominal rating, we believe this would be approx. 0.2 micron, producing a very fine level of filtration.

This filter can be cleaned, so it can be scrubbed clean and put back in the cylinder with an increased flow. The amount of cleaning that needs to be done is dependent on how much sediment is in the water supply and what volume of water is put through the cartridge.

Made in the U.K.
