What are Carbon Filters?

A carbon filter is a type of filter that uses processed carbon to remove chlorine, chloramine,, foul tastes and odours, and other contaminants from drinking water through a process called adsorption. There are different types of carbon filters available, including:

• Carbon block – uses a dense, solid block of fine carbon powder to remove finer particles with high precision.
• Granular activated carbon – uses loose, larger granules for faster flow rates and improving taste and odour.
• Carbon fibre – uses tightly bound carbon fibres to deliver high surface area filtration.

When water passes through the carbon filter, organic compounds naturally stick to the carbon’s surface allowing treated water to flow out of the other end. Carbon filters are therefore highly effective, with millions of microscopic pores that provide a huge surface area for trapping impurities.

There are many benefits to choosing a carbon filter, including:

• Improving the taste and odour of water
• Removing a wide range of contaminants such as organic chemicals, chlorine byproducts, VOCs, and more
• Versatility

How to Choose the Right Carbon Filter

When choosing the right carbon filter for your needs, you should consider certain factors, including:

1. Water source – distinguish whether you have mains water, a private borehole, surface water, etc., as different sources have different contamination risks.
2. Contaminants – next, understand the contaminants you need to remove, such as chlorine, chloramine, volatile organic compounds, heavy metals, etc. You can do this by testing your water.
3. Determine required flow rate – higher flow rates may require larger or multiple cartridges.
4. System size – consider your existing housings, check compatibility with certain standards or certifications.
5. Budget – compare the initial cost of the cartridge to the cost throughout its lifespan. E.g. filter replacements, maintenance, and cleaning.
6. Maintenance expectations – the service life of your filter can depend on the carbon type, water quality, and usage. For example, some filters may need to be changed every 6-12 months depending on the load.

Maintenance and Replacement Guidance

Proper maintenance is essential for helping your carbon filter continue to perform effectively. Therefore, we recommend the following maintenance tasks:

• Regularly change the pre-filter to prevent clogging
• Check taste/odour and performance regularly
• Follow manufacturer requirements and specifications

It’s also important to know when your filter is ready to be replaced. This is usually every 6-12 months, but warning signs often include:

• Return of tastes or odours in the water
• Reduced chlorine reduction in test results
• Noticeable drop in flow rate

If you’re unsure if your carbon filter is in need of replacement, we can help. Call us today, and we can discuss any signs.

FAQs

How often should I replace a carbon filter?

Most carbon cartridges require replacement every 6–12 months, depending on water quality, usage and the system’s capacity. High-sediment or high-contaminant applications may require more frequent changes.

Are carbon filters suitable for drinking water?

Yes. Carbon filtration is widely used for improving taste, odour and clarity and is common in drinking water systems.

Can carbon filters reduce limescale?

Not usually. Carbon filters target chemical contaminants and taste and odour rather than hardness minerals. For limescale issues, you’ll need a water treatment solution.

Do carbon filters remove bacteria or viruses?

Standard carbon filters do not remove bacteria or viruses. If microbiological protection is needed, some carbon filters are rated at 0.5um for cyst removal, however you can consider adding UV disinfection to your filtration process.
