Keep your water filtration system working effectively with Aquafilter replacement filter cartridges and multi-stage filter sets. Regular cartridge replacement is an important part of maintaining a water filtration system, helping to preserve filtration performance, maintain water flow and protect downstream equipment.

Choose from sediment filters, activated carbon cartridges, water-softening filters, iron-reduction cartridges and specialist replacement sets for selected Aquafilter systems.

Whether you need a replacement 10-inch filter cartridge, a set of filters for a domestic water purifier or cartridges for a whole-house filtration system, selecting the correct replacement is essential for compatibility and performance.

Types of Aquafilter Replacement Cartridges

Different filter cartridges use different materials and filtration processes. The right choice depends on your incoming water quality, filtration system and the substances you want to reduce.

Sediment Filter Cartridges

Sediment cartridges are designed to capture suspended particles such as sand, rust, silt and other physical impurities in water. They are commonly installed as the first filtration stage in domestic and whole-house water filtration systems.

Aquafilter offers several types of sediment cartridge, including melt-blown polypropylene and polypropylene yarn filters. Available micron ratings include options such as 1, 5, 10 and 20 microns, depending on the cartridge model.

A lower micron rating generally indicates finer particle filtration, although the actual performance also depends on the cartridge construction and manufacturer's specifications.

Sediment filters can help protect downstream carbon cartridges, membranes, plumbing components and appliances from suspended particles. Choose a cartridge with the appropriate micron rating for your system and water conditions.

Activated Carbon Filter Cartridges

Activated carbon cartridges are commonly used to reduce chlorine, unpleasant tastes and odours, and certain organic compounds. They are often installed as part of a multi-stage water filtration system to improve the taste and odour of treated water.

Carbon cartridges are available in different formats, including carbon block and granular activated carbon. Some specialist cartridges combine carbon filtration with additional media to provide more than one treatment function.

For best results, check the individual product specifications to understand which substances the cartridge is designed to reduce and which filtration systems it is compatible with.

Water-Softening Filter Cartridges

Water-softening cartridges are designed for applications where calcium and magnesium contribute to water hardness and limescale formation.

Many Aquafilter softening cartridges use ion-exchange resin to reduce hardness minerals as water passes through the cartridge. Depending on the cartridge design, specialist media may also help reduce certain other substances, such as iron.

These filters can be useful in selected domestic filtration applications and may help reduce scale build-up in compatible appliances and equipment.

Check the cartridge's specifications and capacity before purchasing, as replacement intervals depend on the incoming water hardness, water consumption and cartridge design.

Iron-Reduction Filter Cartridges

Iron-reduction cartridges are designed for specific water treatment applications where iron is present in the incoming water. Depending on the filtration media, these cartridges may be used as part of a multi-stage treatment arrangement.

The suitability of a cartridge depends on the concentration and form of iron in the water, as well as other water quality conditions. For higher iron concentrations or more complex water quality problems, a dedicated treatment system may be more appropriate than a standard replacement cartridge.

Multi-Stage Replacement Filter Sets

Multi-stage filter sets contain several cartridges designed to work together in a compatible filtration system. Each stage performs a particular treatment function, such as sediment reduction, carbon filtration or water softening.

Using a complete replacement set makes it easier to maintain a multi-stage water purifier without having to identify and purchase every cartridge separately.

Our range includes Aquafilter replacement sets for selected systems, including EXCITO models and other compatible water filtration arrangements. Always check the set contents and model compatibility before ordering.

10-Inch and 20-Inch Water Filter Cartridges

Filter cartridge size is one of the most important factors when selecting a replacement.

Aquafilter replacement cartridges are available in different standard lengths and diameters, including:

  • 10-inch standard cartridges: Commonly used in domestic water filter housings and compact filtration systems.
  • 20-inch cartridges: Used in larger filter housings and systems requiring greater cartridge capacity.
  • 2.5-inch diameter cartridges: Standard-size cartridges for compatible housings.
  • 4.5-inch diameter cartridges: Larger-diameter cartridges, often referred to as Big Blue-style filters.

A cartridge's length and diameter must match the filter housing. A cartridge that looks similar may not fit correctly, so always confirm the dimensions before purchasing.

How Often Should You Replace Water Filter Cartridges?

Replacement frequency depends on the cartridge type, water quality, daily consumption and manufacturer's recommendations.

Sediment cartridges may need replacing sooner where incoming water contains high levels of suspended particles. Carbon and specialist media cartridges also have finite treatment capacities and should be changed according to the manufacturer's guidance.

Signs that a cartridge may need attention include:

  • Reduced water flow or pressure.
  • Visible dirt or discolouration in a sediment cartridge.
  • Changes in the taste or odour of filtered water.
  • Reaching the recommended service interval.
  • A filter system indicator showing that replacement is due.

Do not rely on appearance alone to determine whether a cartridge is still effective. Some filtration media become exhausted without an obvious visual change.

How to Choose the Correct Replacement Filter

Before ordering a replacement cartridge or filter set, check the following:

  1. Filter model: Identify the manufacturer and model number of your existing cartridge or filtration system.
  2. Cartridge dimensions: Confirm the length and diameter, such as 10-inch or 20-inch and 2.5-inch or 4.5-inch.
  3. Micron rating: Choose a suitable sediment filtration rating for your application.
  4. Filter media: Confirm whether you need polypropylene sediment filtration, activated carbon, ion-exchange resin or another specialist media.
  5. Connection and housing compatibility: Check that the cartridge is designed for your existing filter housing or system.
  6. Replacement set contents: If purchasing a multi-stage set, verify that it contains all the required stages and matches your system model.

If you are unsure which cartridge you need, compare the model number and dimensions of your existing filter with the product specifications before purchasing.
