## Big Blue 20″ × 4.5″ Water Filter Housing

The **Big Blue 20″ × 4.5″ water filter housing** provides reliable support for high-capacity water filtration. It holds compatible 20-inch sediment and carbon filter cartridges for rainwater and mains water systems.

This durable housing suits residential, rural and commercial water filtration applications. In addition, its large-diameter design accommodates high-capacity cartridges for greater filtration needs.

## Key Features

– Suits standard 20″ × 4.5″ Big Blue filter cartridges
– Durable construction for water filtration systems
– Suitable for rainwater and mains water applications
– Accommodates compatible sediment and carbon cartridges
– Ideal for new installations or replacement housings
– Suitable for single, twin and triple filtration configurations
– Designed for larger-capacity filtration requirements

## Flexible Water Filtration

This Big Blue filter housing allows you to select cartridges that suit your water supply. For example, a sediment cartridge can help reduce dirt, rust and suspended particles.

Alternatively, a compatible carbon cartridge can help reduce chlorine, unwanted taste and odour. However, filtration performance depends on the cartridge you install.

The 20-inch housing also accommodates larger cartridges than the 10-inch model. As a result, it offers a practical option for higher-capacity filtration systems.
