Big Blue Filters in Australia: A Reliable Whole-House Water Filtration Solution by CoPure

5, Jan 2026

Clean, safe water is essential for every Australian home—whether you live in a metropolitan area, a regional town, or rely on bore/well water in remote locations. With rising sediment levels, ageing pipes, and varying water quality across states, more households are turning to point-of-entry (POE) filtration systems that deliver consistent, contaminant-free water straight into the home.

Among these solutions, Big Blue Filters in Australia have rapidly grown in popularity due to their high flow rate, durability, and ability to handle whole-house applications without compromising pressure. CoPure’s Big Blue series is engineered to meet Australian conditions, supporting everything from urban municipal supplies to high-sediment bore water.

What Are Big Blue Filters?

Big Blue Filters are large-capacity water filtration systems designed for high-flow residential, commercial, and light industrial applications. They typically use a two-stage or three-stage filtration setup, where water passes through successively finer micron ratings.

A standard setup usually includes:

  1. Stage 1 – Sediment filter (5–20 micron): Removes dirt, rust, sand, and large particles.

  2. Stage 2 – Carbon block filter (0.5–10 micron): Removes chlorine, organic chemicals, odours, and taste contaminants.

  3. Optional Stage 3 – Specialised filter: For iron, heavy metals, fluoride, or microbial reduction, depending on water conditions.

Because of their wider 4.5-inch diameter housing, Big Blue Filters offer longer filter life, higher contaminant-holding capacity, and better performance under heavy water usage.

Why Big Blue Filters Are Popular in Australia

Australian homes often face water challenges that require a robust POE filtration system:

  • Sediment presence from older pipe networks

  • High chlorine levels in municipal supplies

  • Turbidity and dissolved solids in regional water

  • Organic matter and odour in rainwater tanks

  • Iron, manganese, and hardness issues in bore water

Big Blue Filters addresses these issues efficiently, making it a preferred choice for Australian homeowners seeking reliability and long-term performance.

CoPure Big Blue Filters: Designed for High-Flow, Whole-House Applications

CoPure’s Big Blue Filters in Australia combine heavy-duty construction, NSF-certified materials, and a user-friendly design, ensuring both performance and longevity. They are particularly effective in homes with multiple bathrooms, large appliances, or high daily water demand.

Key Advantages of CoPure Big Blue Filters

1. High Flow Rate – Up to 50 L/min per 10″ cartridge

This ensures uninterrupted water pressure even when multiple taps, showers, washing machines, or dishwashers run simultaneously. For large homes, this is a critical advantage.

2. Heavy-Duty Housing

Built from impact-resistant materials with a reinforced design, CoPure Big Blue housings withstand:

  • High sediment loads

  • Variable feedwater conditions

  • Up to 125 psi maximum operating pressure

A pressure relief valve makes cartridge changes simple and safe.

3. NSF-Certified Components

All wetted surfaces meet strict NSF standards for safety and materials performance—important for whole-house systems where all water used for drinking, cooking, and bathing passes through the unit.

4. Easy, No-Specialised Tools Installation

Designed for straightforward installation at the point of entry. Filter changes require only a spanner wrench, with no backwashing or regeneration cycles needed.

5. Cost-Effective, Long-Term Operation

Because of their large capacity, Big Blue cartridges last significantly longer than standard-size filters, reducing annual maintenance costs.

How the CoPure Big Blue Filters Work

Stage 1: Sediment Filtration (20” x 4.5” – 5 Micron)

This stage removes:

  • Sand

  • Rust flakes

  • Silt

  • Organic particles

Using a 5-micron filter ensures protection for both the water system and downstream carbon cartridges.

Stage 2: Carbon Block Filtration (20” x 4.5”)

This high-performance activated carbon block:

  • Removes up to 99% of chlorine

  • Reduces pesticides and VOCs

  • Improves taste and odour

  • Reduces colour and chemical impurities

Carbon block filters are significantly more efficient than granular carbon due to their increased surface area and longer contact time.

Benefits of Big Blue Filters for Australian Households

1. Improved Water Quality

Removes sediment, chlorine, organic chemicals, and bad taste/odour—making water safer for both consumption and daily use.

2. Protection for Appliances and Plumbing

Filtered water extends the lifespan of:

  • Hot water systems

  • Dishwashers

  • Washing machines

  • Shower fittings

  • Solar heating units

By preventing sediment buildup, you reduce repair and replacement costs.

3. Better Water Pressure

Big Blue Filters maintain consistent water pressure even at high usage points, unlike smaller filters that often restrict flow.

4. Peace of Mind

Knowing your water is free from harmful or unpleasant contaminants is especially important for families, children, and rural households.

Ideal Applications Across Australia

CoPure Big Blue Filters are particularly suited for:

  • Homes with multiple people and heavy water usage

  • Homes on bore/well water with high sediment or mineral content

  • Remote and regional areas with inconsistent water quality

  • Rainwater tank systems need advanced purification

  • Small businesses, cafés, and workshops require clean water for equipment

Given Australia’s diverse water environments—from Queensland rainwater tanks to Victorian municipal supply and WA hard water—these filters provide a reliable universal solution.
