0.5 Micron Coconut Carbon Block Water Filter Cartridge | 20” x 4.5” Universal Replacement for Whole House Filter

Improve taste, clarity, and overall water quality with this 0.5 Micron Coconut Carbon Block Water Filter Cartridge. Designed for effective chemical reduction, this high-performance carbon block removes chlorine, unpleasant tastes and odours, VOCs, and fine particulates commonly found in town water supplies.

Manufactured using 100% premium coconut shell activated carbon, the dense carbon block structure maximises contact time for reliable contaminant reduction while maintaining consistent flow throughout the home.

Key Features

  • 0.5 Micron Filtration – Reduces fine sediment, chlorine, and volatile organic compounds (VOCs).

  • Coconut Shell Activated Carbon – Naturally improves taste and odour through high adsorption efficiency.

  • NSF/ANSI 42 Performance – Designed for chlorine taste and odour reduction.

  • High-Density Carbon Block – Maximises contaminant contact time for improved performance.

  • Universal Fit – Standard 20” x 4.5” size suits most whole house filter housings.

  • Food-Grade Construction – BPA-free materials for safe household water use.

  • Long Service Life – Typical replacement interval up to 12 months, depending on water quality and usage.

  • Protects Downstream Components – Helps reduce chemical exposure to plumbing and appliances.

Why Choose a Coconut Carbon Block Filter?

Coconut shell carbon offers a tighter pore structure and higher adsorption capacity than granular carbon alternatives, making it highly effective at removing chlorine-related compounds that affect water taste and smell.

Ideal for homes on mains water seeking cleaner, better-tasting water throughout the house, this cartridge is a reliable replacement option for any 20” x 4.5” whole house filtration system.

What This Filter Does

This 0.5 micron coconut carbon block filter is designed to reduce chlorine, chemical tastes, and odours after sediment filtration.

The dense carbon block structure increases contact time, improving adsorption efficiency and delivering cleaner, better-tasting water throughout the home.

This cartridge is typically used as the final carbon stage in a standard whole-house filtration setup.

What It Removes

This filter helps reduce:

  • Chlorine (taste & odour)

  • Chemical tastes and smells

  • Volatile Organic Compounds (VOCs)

  • Fine particulate matter down to 0.5 micron

It is not designed for PFAS or chloramine removal — that function is handled by the premium catalytic carbon filter.

  • Yes. It is designed for whole-house systems using 20” x 4.5” housings.

  • This cartridge is designed primarily for chlorine taste/odour and general chemical reduction. Chloramine and PFAS require specialised media and performance depends on the specific filter design and contact time. For targeted chloramine + PFAS reduction, use our premium catalytic carbon PFAS filter.

  • This 0.5 micron coconut carbon block filter has a tighter pore structure than 1 micron carbon cartridges, allowing for greater contact time and improved reduction of chlorine, tastes, odours, and fine chemical particulates. The finer micron rating provides additional polishing of the water before it reaches fixtures and appliances.

  • Yes. Coconut shell activated carbon is highly effective at reducing free chlorine, which is responsible for unpleasant tastes and odours in mains water. This filter is designed specifically for whole-house chlorine reduction and taste improvement.

  • When installed after proper sediment filtration, pressure drop is minimal. The high-density carbon block is engineered to balance fine filtration with adequate flow. Any noticeable pressure reduction usually indicates the filter is approaching the end of its service life.

  • Most homes should replace this filter every 6–12 months, depending on:

    • Incoming chlorine levels

    • Household water usage

    • Water temperature and quality

    If chlorine taste or odour begins to return, replacement is recommended regardless of time in service.

When to Replace

Replace this filter when:

  • Chlorine taste or odour begins to return

  • Water flow rate noticeably decreases

  • The filter reaches 6–12 months of use, depending on water quality and demand

Timely replacement maintains performance and protects downstream plumbing and appliances.

Compatibility Note

This cartridge suits all Pure₂O Whole-House Water Filtration Systsems, as well as all standard 20” x 4.5” (Big Blue) housings only.

❌ Not compatible with:

  • 10” slimline housings

  • Undersink or benchtop systems

Always confirm housing size before ordering.
