The HALO 5 is a legitimate whole-house carbon filter with a magnetic "water conditioner" added in-line. The carbon stages are real; the magnet removes nothing, and HALO's own FAQ says the water will not test soft. Published installed prices run from $2,000 to $7,499. Here is what is in the tank from HALO's own spec sheet, what owners complain about, and what I tell city water callers to put in instead.
