WH002B-RFI Triple Whole House System (Big Blue Housings)
The WH002B-RFI is built using Taiwanese-made Big Blue housings (20" x 4.5") for excellent flow and low restriction. Because of the large cartridge size, typical pressure drop is no more than ~5psi when first installed (depending on cartridge choice and flow). Designed to treat water at up to 20 litres per minute, it’s a strong performer for medium to larger households.
Don’t overpay for whole-house filtration. This system uses industry-standard 20" x 4.5" cartridges (no proprietary sizes), and we can refer you to trusted local plumbers for installation.
Suitable for wall-mounting and typically installed near the water meter or where your mains enters the home. For smaller homes or units, consider a twin-stage alternative.
Please note: Cartridges are not included. Choose your Stage 1–3 cartridges using the selection advice below.
