Keep your Aquafilter EXCITO-ST water filtration system performing effectively with the Aquafilter EXCITO-CRT 4-Piece Replacement Cartridge Set. This genuine Aquafilter replacement set contains four inline cartridges designed to provide sediment filtration, chlorine reduction and activated carbon treatment for compatible EXCITO-ST under-sink water filtration systems.

Combining polypropylene sediment filtration, coconut-shell granular activated carbon and specialist KDF media, the four cartridges help reduce suspended particles, chlorine, selected organic compounds and certain heavy metals. They also help improve the taste and smell of filtered drinking water.

Four-stage replacement filtration

The Aquafilter EXCITO-CRT contains four replaceable inline cartridges:

• 1 × AIPRO-20M-AQ sediment cartridge

• 1 × AIPRO-1M-AQ fine sediment cartridge

• 1 × AICRO-L-AQ activated carbon cartridge

• 1 × AICRO-L4-AQ activated carbon and KDF cartridge

Each cartridge performs a different filtration function, helping maintain the treatment sequence of the EXCITO-ST system.

Stage 1 – AIPRO-20M-AQ sediment cartridge

The first stage uses polypropylene filtration media to reduce larger suspended particles in the incoming water.

It helps capture:

• Sand

• Silt

• Rust

• Suspended solids

• Other visible sediment

This initial filtration stage helps protect the downstream cartridges from larger particles.

Stage 2 – AIPRO-1M-AQ fine sediment cartridge

The second stage provides additional mechanical filtration using polypropylene media.

With a nominal 5-micron rating, it helps capture finer suspended particles that may pass through the first sediment cartridge.

It helps reduce:

• Fine sediment

• Rust particles

• Sand

• Other suspended solids

This additional filtration helps prepare the water for the activated carbon stages.

Stage 3 – AICRO-L-AQ coconut-shell activated carbon cartridge

The third stage contains granular activated carbon made from coconut shells.

Activated carbon helps reduce free chlorine, selected organic compounds and certain pesticides. It also helps improve the taste and aroma of filtered water.

Key benefits include:

• Chlorine reduction

• Improved taste and odour

• Reduction of selected organic substances

• Reduction of certain pesticides

The carbon media provides adsorption treatment as water passes through the cartridge.

Stage 4 – AICRO-L4-AQ activated carbon and KDF cartridge

The final stage combines granular activated carbon with KDF media.

The activated carbon provides further reduction of chlorine and selected organic compounds, while KDF media uses oxidation-reduction reactions to help reduce certain dissolved metals.

Depending on incoming water conditions, the media can help treat:

• Iron

• Copper

• Lead

• Mercury

• Arsenic

• Hydrogen sulphide

• Other selected dissolved contaminants

KDF also has bacteriostatic properties that help inhibit bacterial growth within the cartridge. This should not be confused with sterilisation or guaranteed disinfection of drinking water.

Compatible with Aquafilter EXCITO-ST systems

The EXCITO-CRT is one of Aquafilter's four-cartridge replacement configurations for the EXCITO-ST system.

It is particularly important to distinguish this set from the standard EXCITO-ST-CRT replacement set.

The EXCITO-CRT contains:

• Two polypropylene sediment cartridges

• One coconut-shell activated carbon cartridge

• One activated carbon and KDF cartridge

Unlike EXCITO-ST-CRT, this configuration does not contain the AISTRO-L-AQ ion-exchange water-softening cartridge.

Check the cartridge models in your existing system before ordering to ensure compatibility.

The 5-micron rating relates to the fine sediment filtration stage; it should not be interpreted as the filtration rating of every cartridge in the set.

Installation and maintenance

Replace the cartridges in accordance with Aquafilter's installation and maintenance instructions.

Before installation:

• Shut off the water supply.

• Check that the replacement cartridge models match your existing configuration.

• Confirm that the threaded connections and fittings are compatible.

• Follow the correct water-flow direction marked on each cartridge.

After installation, restore the water supply carefully and check all connections for leaks. Flush the system according to the manufacturer's instructions before drinking the filtered water.

Cartridge service life depends on incoming water quality, sediment levels, contaminant concentrations and household water consumption. Replace cartridges according to the manufacturer's recommended maintenance schedule and sooner if water flow or taste deteriorates.
