Salt-free scale conditioner
HALO ION 2.0 Plus
The HALO ION 2.0 Plus is the salt-free conditioning technology from the HALO 5 offered as a standalone unit. It clamps in-line on the main pipe and treats hard water so it stops forming scale — with nothing to power, refill or drain.
Magnetic conditioning, not softening
The ION 2.0 uses multi-reversing-polarity permanent magnetic fields to alter how dissolved calcium and magnesium behave, keeping them suspended so they flow through instead of crystallising onto pipe walls, elements and fixtures. Over time it also breaks down scale that is already in the system.
It does not remove the minerals — the water is not "soft" in the ion-exchange sense and there is no added sodium — but scale stops accumulating.
Why people choose it
No salt to carry, no drain to plumb, no power, no service visits, and a 25-year warranty (parts and labour covered for the first 10). It is a strong fit where salt discharge is restricted, where there is no drain near the water entry, or as an add-on to an existing carbon filter.
