Whole-home filtration & conditioning
H2 ZERO Scale Media
The H2 ZERO Scale Media system splits filtration and conditioning across two tanks. The first holds High Activity Carbon for chlorine, taste and odour; the second holds either the HALO ION conditioner or HALO's proprietary salt-free scale media, depending on the water and the budget.
Carbon first, conditioning second
Tank one uses HAC carbon that meets NSF/ANSI Standard 61 and food-grade chemical standards to strip free chlorine and clean up taste and odour. Tank two either runs the HALO ION magnetic conditioner or a bed of salt-free scale-control media — both keep calcium and magnesium from bonding into limescale, and neither needs salt or a drain.
Like the rest of the H2 ZERO line, it is fully passive: no electricity, no backwash cycle, no wastewater.

Choosing the second tank
HALO ION carries the longer 10-year warranty and dissolves existing scale over time; the scale media option is lower cost with a 5-year warranty. Milani recommends one based on your hardness and how much existing scale is in the system.
- Chlorine, taste and odour reduction
- Salt-free scale prevention
- No power or drain connection
- 10-year carbon warranty
How Milani installs and looks after it
Milani installs HALO equipment on the main line where water enters the home (or, for drinking-water and point-of-use units, under the kitchen sink), tests your water first so the system is matched to what you actually have, and sets it up with the correct bypass and shut-offs so future service is simple. Where a unit has replaceable cartridges or media, we tell you the schedule and supply the parts.
At a glance
- Tank 1: High Activity Carbon (NSF/ANSI 61)
- Tank 2: HALO ION or salt-free scale media
- Zero electricity, zero backwash, zero waste
- No salt required
- 10-year carbon warranty; 10-yr ION or 5-yr scale media
Warranty
The carbon media carries a 10-year limited warranty. The second tank is warranted 10 years for HALO ION or 5 years for scale media. Milani registers the system at installation.
