A single-stage 10" × 4.5" whole-house carbon filter — the short Big Blue format. The 4.5" diameter sits between the slim 10" × 2.5" residential format and the full 20" × 4.5" Big Blue standard. For homes wanting Big Blue flow capacity but with limited vertical space for a 20" cartridge, this is the right format.
Why 4.5" Diameter Matters for Whole-House Flow
A standard 10" × 2.5" cartridge restricts whole-house flow noticeably during peak demand events — multiple showers, dishwasher, washing machine simultaneously. The 4.5" wide Big Blue housing accommodates a significantly larger carbon block cartridge, delivering:
- Higher flow capacity — no perceptible pressure drop during peak household demand
- Longer cartridge life between replacements — bigger media volume holds more chlorine adsorption capacity
- Better contact time — water spends longer in contact with the carbon media for finer chemical reduction
What It Does
- Removes chlorine and chemical taste from chlorinated supplies
- Reduces odour and the swimming-pool smell of heavily-chlorinated water
- Captures organic impurities affecting taste and clarity
- Improves water quality at every fixture without sacrificing flow rate
For sediment removal, pair with the 10" × 4.5" sediment housing or step up to the 2-stage sediment + carbon configuration.
Build
- Housing: heavy-duty Big Blue
- Mounting: steel mounting bracket for secure wall installation
- Ports: 1" inlet and outlet — correct for Australian mains supply
- Cartridge: 10" × 4.5" carbon block
Installation
Professional installation recommended. Connects to cold mains supply line at the point of entry. The 1" connections accept the standard Australian mains supply line without reducers.
