Our starting option for whole-house carbon filtration. Official model: H2 ZERO Carbon Only.

02 / Compact filtration
Small footprint. Two stages. MINI 2 combines sediment filtration with an UltraFlow carbon cartridge.

03 / Filtration + conditioning
Officially HALO H2 ZERO ULTIMATE: carbon filtration and salt-free conditioning in one main tank.

04 / Recommended flagship
Layered filtration, automatic media-bed backwashing, and salt-free conditioning for whole-house use.
Optional add-on: Ask about Defender II for specified PFOS/PFOA, lead, and cyst reduction. We match its flow limits and installation requirements to your system. Contact us for a quote on any option.

01 / HALO H2O · Starting option
HALO H2O, officially H2 ZERO Carbon Only, puts high-activity carbon in a single whole-house tank. It is a straightforward starting point when free-chlorine taste and odor are your main concerns.
Carbon-only filtration does not soften water or include HALO ION conditioning. Sizing, pretreatment, and service needs depend on your water and the current installation instructions.

Working with limited installation space? HALO MINI 2 brings two-stage whole-house filtration into a compact cartridge system, without an electrical connection or backwash drain.
This MINI 2 configuration does not include integrated salt-free conditioning. We confirm model, flow capacity, pressure loss, and cartridge service requirements with your quote.

03 / HALO H2 ZERO ULTIMATE
Want to address chlorine taste and odor without a powered backwashing tank? H2O Ultimate combines high-activity carbon with HALO ION conditioning. Its main unit needs no electrical connection and produces no routine backwash discharge.
The current manual includes a separate Sediment Guard, with an annual filter-replacement instruction. Additional pretreatment depends on your water. Conditioning does not remove calcium and magnesium or deliver ion-exchange-softened water. The written warranty has 10-year provisions and specific conditions; freight and on-site labor are excluded.

HALO 5 pairs carbon filtration with mineral filtration layers and an inline conditioner. Automatic backwashing resets the media bed, helping maintain water contact through the tank.
HALO describes HALO 5 water as conditioned, highly filtered, and alkaline. Actual pH depends on the incoming water; this description is not a guaranteed pH increase or a molecular-hydrogen claim.
HALO 5 requires power and a drain. Its WQA certifications cover NSF/ANSI/CAN 61 material safety and 372 lead-free compliance, not contaminant-reduction performance. HALO’s maintenance-free marketing concerns routine media service; the written warranty, water conditions, and normal plumbing care still apply.

Optional add-on / HALO DEFENDER II
Add Defender II to a suitable HALO installation when specified lead, PFOS/PFOA, or cyst reduction is a priority. We review the specific claims, combined pressure loss, and operating limits before recommending it. Defender II uses a 0.5-micron carbon-block cartridge and a flow meter connected to a filter-life Smart Monitor.
*Published capacity and flow for the specified lead/PFOS-PFOA reduction application; not an unrestricted whole-house flow promise. Higher demand may require parallel units. HALO requires an SG-520 prefilter and indoor installation. The sheet lists NSF/ANSI 53 certification through IAPMO R&T for specified claims. Chlorine/chloramine figures have different test conditions. The limited warranty is 10 years on the tank and one year on cartridges and electronics; exclusions apply.

Defender II is an optional add-on for specified PFOS/PFOA, lead, and cyst reduction; suitability and flow must be checked. The best combination depends on your source water, simultaneous fixture demand, space, and the exact contaminants of concern. These systems do not replace disinfection when water is microbiologically unsafe.

Before you choose
No. Salt-free conditioning leaves calcium and magnesium in the water. If your goal is lower measured hardness, ask us about a properly sized ion-exchange softener. Mineral spotting can still occur with conditioning.
A layered design may make sense when you want general filtration or conditioning plus targeted reduction. We must check layout, prefiltration, available pressure, combined pressure loss, and the applicable flow limits before proposing a combination.
Well water needs a current laboratory analysis and HALO review before equipment is selected. Iron, manganese, bacteria, acidity, and sediment may need separate treatment. The standard municipal-water package is not automatically a complete well-water solution.
No. Coverage differs by model and component. Installation, maintenance, water conditions, purchase eligibility, registration where required, and exclusions matter. Ask for the applicable written warranty with your estimate.
Your written estimate depends on system size, pipework, access, drain and power needs, and any additional treatment. Tell us about your home so we can quote an appropriate scope rather than an incomplete headline price.
