Product Options

Standard — Waimana 10CTO05

The Waimana 10CTO05 combines activated carbon block media with 5 micron filtration in a 10" Jumbo cartridge.

Its activated carbon block provides a practical treatment stage for potable cold-water systems while also helping capture fine suspended sediment as water passes through the cartridge.

With a rated flow of up to 40 L/min, it is a strong choice for residential filtration systems where you want carbon treatment and sediment filtration in one Jumbo cartridge.

Choose Standard for dependable everyday carbon block filtration at a lower price point.

Premium — Davey Microlene ACB10J

The Davey Microlene ACB10J is a high-capacity activated carbon cartridge designed for drinking-water treatment.

Its bonded powdered activated carbon media combines 5 micron nominal filtration with reduction of:

• Chlorine
• Unpleasant taste
• Odour
• Pesticides
• Dissolved chemicals
• Sediment

The Jumbo cartridge has a documented treatment capacity of 45,400 litres, a maximum flow rate of 23 L/min, and an optimal treatment flow of 7.6 L/min.

The high-porosity carbon block is designed to support good flow through the media while helping reduce pore plugging from sediment, which can help maximise carbon life.

Why Choose This Water Filter Cartridge?

• 5 micron filtration — captures fine suspended sediment as part of the treatment process.
• Activated carbon block media — adds carbon treatment to your filtration system.
• 10" Jumbo format — provides more media than a standard-diameter cartridge.
• Two treatment levels — choose Standard for straightforward carbon block filtration or Premium for documented treatment capacity and contaminant-reduction performance.
• 40 L/min Standard flow rate — practical for general residential filtration.
• 23 L/min Premium maximum flow — matched with a lower optimal treatment flow for effective carbon contact time.
• Premium 45,400 L treatment capacity — gives the Davey cartridge a clearly defined water-volume capacity.
• Improved drinking-water quality — the Premium Davey targets chlorine, taste, odour, pesticides and dissolved chemicals.

How It Works

Water passes through the activated carbon block, where two filtration processes take place.

The 5 micron structure captures fine suspended particles, while the activated carbon media treats the water as it travels through the cartridge.

Activated carbon provides a large internal surface area for water treatment. The Premium Davey cartridge uses a high-capacity bonded carbon block designed to reduce taste, odour, chlorine, pesticides, dissolved chemicals and sediment.

For carbon filtration, contact time matters. The Davey cartridge therefore has an optimal treatment flow of 7.6 L/min, even though the cartridge can handle a higher maximum flow of 23 L/min.

Best Suited For

This 10" Jumbo 5 micron carbon block water filter cartridge is well suited to:

• Drinking water filtration
• Residential water filtration
• Whole-house treatment systems
• Town-supply water
• Taste and odour treatment
• Chlorine reduction
• Fine sediment filtration
• Tank-water treatment systems
• Final-stage filtration
• Beverage applications
• Food-industry water treatment
• Commercial drinking-water systems

The Premium Davey is particularly useful where a documented treatment capacity and dissolved-contaminant reduction are important.

Key Specifications

Standard vs Premium — Which Should I Choose?

Choose Standard Waimana if you want:

• 5 micron carbon block filtration
• Activated carbon treatment
• 40 L/min rated flow
• A 10" Jumbo cartridge for potable cold water
• Fine sediment filtration and carbon treatment in one cartridge
• A practical, cost-effective replacement option

For straightforward residential filtration, Standard provides the core benefits of a 5 micron activated carbon block without paying for the Premium cartridge's documented treatment capacity.

Choose Premium Davey if you want:

• 45,400 L documented treatment capacity
• 23 L/min maximum flow
• 7.6 L/min optimal treatment flow
• Reduction of chlorine
• Reduction of taste and odour
• Reduction of pesticides
• Reduction of dissolved chemicals
• 5 micron nominal sediment filtration
• High-capacity bonded activated carbon
• Maximum operating temperature of 82.2°C

The main reason to choose Premium is documented carbon-treatment performance and capacity.

Flow Rate — What Do the Numbers Mean?

The flow figures for these two cartridges are not quite the same type of specification.

The Waimana 10CTO05 has a rated flow of up to 40 L/min.

The Davey ACB10J has a maximum flow rate of 23 L/min and an optimal treatment flow of 7.6 L/min.

For activated carbon filtration, slower flow gives the water more contact time with the carbon media. That is why the Davey optimal treatment flow is lower than its maximum flow rate.

Installation

This cartridge is designed for use in a compatible 10" Jumbo water filter housing.

To replace the cartridge:

1. Turn off the water supply.
2. Release pressure from the filter housing.
3. Remove the filter housing sump.
4. Remove the existing cartridge.
5. Clean the housing if required.
6. Check that the O-ring is clean and seated correctly.
7. Insert the new carbon cartridge.
8. Reassemble the housing.
9. Slowly restore water pressure.
10. Check the housing for leaks.

For a newly installed carbon cartridge, flush the filter before drinking the water.

For the Davey ACB cartridge, run water through the new cartridge for at least 5 minutes after installation to remove carbon fines. Davey also recommends flushing for around 20 seconds before drinking after periods of non-use.

Maintenance

Carbon cartridges should be replaced as the media reaches the end of its useful treatment life.

Actual service life depends on water quality, usage, flow rate and the concentration of contaminants being treated.

Standard — Waimana

Replace around every 12 months, or sooner if water quality noticeably reduces.

Premium — Davey Microlene

The Premium Davey Jumbo cartridge has a documented treatment capacity of up to 45,400 litres.

Replacement timing will depend on water usage and incoming water quality, so both treatment capacity and time in service should be considered.

Frequently Asked Questions

What does a carbon block water filter do?

A carbon block cartridge combines activated carbon treatment with sediment filtration.

As water passes through the carbon media, the cartridge captures particulate matter while the activated carbon treats the water.

The Premium Davey specifically reduces taste, odour, chlorine, pesticides, dissolved chemicals and sediment.

What does 5 micron mean?

The 5 micron rating refers to the cartridge's particulate filtration level.

It provides fine sediment filtration while the activated carbon performs the additional water-treatment function.

What's the difference between Standard and Premium?

The Standard Waimana provides straightforward 5 micron activated carbon block filtration with a rated flow of 40 L/min.

The Premium Davey provides 5 micron nominal filtration plus documented reduction of chlorine, taste, odour, pesticides and dissolved chemicals. It also has a 23 L/min maximum flow, 7.6 L/min optimal treatment flow, and 45,400 litre treatment capacity.

Which option should I choose?

Choose Standard Waimana for general-purpose carbon block filtration and fine sediment removal.

Choose Premium Davey where documented carbon-treatment performance, capacity and contaminant-reduction claims are important.

What is the Davey flow rate?

The Davey ACB10J has a maximum flow rate of 23 L/min.

For best carbon-treatment performance, its optimal flow rate is 7.6 L/min.

Why is the optimal Davey flow lower than the maximum flow?

Activated carbon works best when the water has enough contact time with the media.

Running closer to the 7.6 L/min optimal treatment flow gives the water more time in contact with the carbon than running at the cartridge's 23 L/min maximum flow.

How much water can the Premium Davey treat?

The 10" Jumbo Davey ACB10J has a documented treatment capacity of 45,400 litres.

Actual cartridge life will depend on incoming water quality and usage.

Does it help with chlorine taste and smell?

Yes. The Premium Davey ACB10J is designed to reduce chlorine, taste and odour, making it well suited to improving drinking-water quality.

Should I install a sediment filter before a carbon block?

Where the incoming water has a high sediment load, a separate sediment prefilter can help protect the carbon media and extend its useful life.

Davey recommends prefiltration as a low-cost precaution in high-sediment applications.

Do I need to flush a new carbon filter?

Yes. Flushing removes loose carbon fines that can be present when a new cartridge is first installed.

For the Premium Davey, run water through the cartridge for at least 5 minutes after installation.

Will this fit a 10" Jumbo housing?

Yes. These cartridges are designed for a compatible 10" Jumbo water filter housing.
