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.
