Compact whole-home · 3-stage
HALO Mini 3
The HALO Mini 3 delivers whole-house filtration and conditioning in a cartridge-based unit small enough for a tight utility closet. It captures sediment, filters through carbon for taste and chlorine, and finishes with the permanent HALO ION conditioner for salt-free scale control.
Three stages, compact footprint
Stage one captures sediment down to 5 microns. Stage two is a premium UltraFlow carbon cartridge that improves clarity and taste and reduces chlorine. Stage three is the HALO ION 2.0 permanent magnetic conditioner — it never needs a filter change and keeps hard-water minerals suspended so they do not form scale, while gradually dissolving existing scale.

Where it fits
For condos, townhomes and smaller houses — or anywhere a full tank system will not fit and there is no floor drain — the Mini 3 gives most of the benefit in a fraction of the space. Stages one and two use replaceable cartridges (kit H-MINI-KIT); Milani sets the change interval based on your water.
