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.

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. It gives us whole-house filtration without making the water pressure feel restricted.
We installed this mainly because of the chlorine smell in our mains water. 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.
The change across the whole house was easier to notice than I expected. Shower water feels less harsh and there is much less of that pool-like smell. Installation was tidy and the system is easy to get to when it is time for maintenance.
