Universal Compatibility & Easy Maintenance

The Biotect Ultra (Model 2501) is engineered with a standard M12 thread to fit seamlessly into your existing filtration setup. It is fully compatible with:

• All Doulton tap-mounted countertop/benchtop systems

• All Doulton under-sink/under-bench plumbing systems

• Doulton DUO, Doulton TRIO, and Kingfisher filtration systems

Replacing the cartridge is incredibly straightforward. Turn off the water supply, simply unscrew the old filter housing, twist out the spent cartridge, screw in your new Biotect Ultra cartridge, screw in the filter housing and turn the water supply back on.

Smart Maintenance Tip: If you notice a drop in your water pressure before the 6-month mark, it means the natural ceramic shell is doing its job by trapping sediment. You can easily remove the cartridge and scrub the ceramic surface under running water to restore optimal flow and extend its usage.
