While we build the web pages for the full range, please contact us for other DoultonTM cartridges.

If you want you make sure that either of the two water filter cartridges below are a match for your system, you need to remove your existing cartridge and look for the two O rings:


O ring A is on top of the thread and just below the tip.

O ring B is at the bottom of the thread.

Also, your filter cartridge may have a black ring on the bottom with lettering:
For AVX01 or FRX01 use the Supercarb candles.

For AVX02 or FRX02 use the Ultracarb candles

But the Ultracarb candle also deals with lead, so if lead is not a concern, then the Supercarb candle is ideal and completely interchangeable with the Ultracarb.

Some 3 way Triple Flow tap manufacturers have recently changed the bottom of the filter housing so that at least as efficient, compatible but less expensive cartridges do not fit.
If your filter housing has a slightly rounded bottom; either of the cartridges will fit.
If your filter housing has a flat bottom; only the Ultracarb will fit.

PRICES: For British Mainland, the price you see is the total price you pay (including delivery)
at the extra cost elsewhere - please see "Cart" after you have made your choice.
