Product details
HGW-03 | WHOLE-HOME USE
The HGW-03 treats municipal water before it reaches the connected household outlets, helping reduce sediment and chlorine taste and odour for everyday kitchen, bathroom and laundry use. The final installation must be sized for the property’s plumbing and peak water demand.
HGW-03 | THREE FILTER CARTRIDGES
Three 20-inch cartridges combine a polypropylene (PP) sediment filter, granular activated carbon and a carbon block. The PP cartridge captures suspended particles, while the carbon stages help reduce chlorine taste and odour. This is whole-house filtration; it does not replace an ion-exchange softener for hardness removal.
HGW-03 | PRESSURE MONITORING
Three pressure gauges provide reference readings for monitoring the system. Record normal readings under comparable flow conditions and arrange inspection if pressure or household flow changes noticeably. A gauge reading alone does not measure water quality or prove that a cartridge needs replacement.
HGW-03 | OUTDOOR INSTALLATION
The HGW-03 is installed outdoors near the incoming water supply. Its protective cover shields the housings from direct sunlight and everyday exposure. An appropriately licensed plumber should plan the connections and isolation valves, allowing enough clearance below and in front for cartridge replacement.
HGW-03 | ROUTINE MAINTENANCE
Regular servicing includes cartridge replacement and inspection of the housing seals. Follow the product instructions to isolate the supply and release pressure before opening a housing. Replacement timing depends on water quality, household use and flow changes; HG PureWater can help identify the correct replacement set.
HGW-03 | AFTER-SALES SUPPORT
The HGW-03 includes a 10-year parts warranty, subject to the applicable warranty terms. Keep your purchase and installation records and contact HG PureWater for parts and service guidance. Confirm coverage, exclusions and any labour or call-out charges before arranging work.

Customer feedback
Had this in for a little while now and it's been good. Laundry water smells more neutral now. I'd buy it again.
Good whole-house option for our family. Installer was easy to deal with too.
Laundry and bathrooms have been good since putting it in. Pressure still feels normal in day-to-day use. Glad we went with this one. Definately happy with it.
Simple, neat and works well. The system is tucked away neatly and hasn't affected pressure in any obvious way. The shower glass isn't magically spotless, but cleaning feels easier.
Even the kettle water tastes better to us. Biggest thing we noticed was the water smell and taste improved around the whole house.
Very happy with the purchase. The kids complained less about the tap-water smell. Been easy to live with day to day.
We were renovating, so doing the water at the same time made sense. Would happily recommend it. No issue's so far.
We had the whole-house water filtration system installed recently and noticed the difference straight away. The water tastes cleaner, there is less chlorine smell, and the whole family is very happy with it. The installation was professional, tidy and clearly explained. We’re very pleased with the system and would happily recommend HG PureWater.
Showers feel nicer and the kitchen water is much better than before. The system sits outside and doesn't get in the way. Worth it for our place.
After fitting the whole-house system, the water at every tap feels cleaner. Flow has stayed strong through the house, including when two showers are being used. For us the best result is cleaner-smelling water everywhere, not just at one drinking tap.
We installed this mainly because of the chlorine smell in our mains water. The chlorine smell has dropped significantly, especially in the shower and bathroom basins. So far the cartridges have been simple to check and the maintenance schedule is easy to understand.
This has made our home water feel much more pleasant overall. Flow has stayed strong through the house, including when two showers are being used. So far the cartridges have been simple to check and the maintenance schedule is easy to understand.
