Set of 4 Water Filters EXCITO-ST-CRT AQUAFILTER Water Filter Cartridges

Complete cartridge set for the EXCITO-ST system

The EXCITO-ST-CRT cartridge set was prepared as a comprehensive solution for water filtration in the EXCITO-ST under-sink filter. It provides multi-stage improvement of water quality, including retention of mechanical impurities, reduction of hardness, limitation of selected chemical contaminants, and improvement of the utility properties of water.

In practice, this means better protection of fixtures and appliances, a lower risk of limescale buildup, and more comfortable use of water in the kitchen. The set is suitable where a matched filter cartridge is needed for the original EXCITO-ST setup.

Set contents

1. AIPRO-20M-AQ

• Cartridge with polypropylene nonwoven fabric.
• Effectively removes mechanical impurities such as sand, silt, and rust.
• Foam structure with open-cell microbubbles.

This is the first purification stage, designed to capture visible and fine solid particles present in the water. As a result, the subsequent cartridges work under better conditions, and the entire water filter can operate more effectively.

2. AISTRO-L-AQ

• Softening cartridge with high-quality ion exchange resin.
• Reduces water hardness by exchanging calcium and magnesium ions for sodium.
• Prevents limescale formation and protects household appliances.

This element of the set is responsible for reducing water hardness, which matters both for everyday convenience and for protecting kettles, coffee machines, fixtures, and other devices that come into contact with water.

3. AICRO-L4

• Two-layer cartridge.
• The first layer (KDF media) reduces the concentration of iron, heavy metals, hydrogen sulfide, pesticides, and has bacteriostatic properties.
• The second layer (coconut shell carbon) removes chlorine, chlorinated solvents, and aromatic hydrocarbons, improving the taste and odor of the water.

This is an advanced filtration stage responsible for reducing selected contaminants that affect water quality, odor, and taste. The combination of KDF media and activated carbon from coconut shells increases the versatility of the entire set.

4. AIPRO-1M-AQ

• Similarly to AIPRO-20M-AQ, it effectively filters mechanical impurities.

The final mechanical cartridge supports the final cleaning of the water from solid particles, completing the filtration process carried out by the EXCITO-ST-CRT set.

Main benefits

• Removes mechanical and organic impurities.
• Reduces the concentration of heavy metals and iron.
• Removes unpleasant taste and odor from water.
• Reduces water hardness.
• Effectively removes free chlorine and pesticides.

As a result, the cartridge set fits well with the needs of users who expect a convenient and effective solution for everyday water treatment under the sink. Although it is not a reverse osmosis system or an osmosis filter, it is a practical alternative for people choosing a classic water filtration system without an RO membrane.

Operation and important notes

Regular replacement of the cartridges helps maintain stable filtration efficiency and the full utility benefits of the set. This is especially important for cartridges responsible for softening and improving the organoleptic properties of water.

What applications is this set suitable for?

The EXCITO-ST-CRT set is intended for the EXCITO-ST under-sink filter and can be used wherever improving the quality of water used for drinking and everyday kitchen tasks matters. It is a good choice for users who want to reduce deposits, improve the taste of drinks and food, and take care of the better condition of devices that come into contact with water.

Compared with solutions such as reverse osmosis, a reverse osmosis filter, or a full reverse osmosis system, this set works as a classic line cartridge system. Thanks to this, it remains simple to use and replace components, while still providing a broad improvement in water quality.

Why choose EXCITO-ST-CRT?

The Set of 4 Water Filters EXCITO-ST-CRT AQUAFILTER is a solution for people who expect a complete and matched replacement set for the EXCITO-ST system. It combines protection against mechanical impurities, softening, and improvement of water taste and odor, while helping protect fixtures and household appliances from the negative effects of hard water and the presence of selected contaminants.

It is a sensible choice for users who want to maintain high filtration quality in their home system and enjoy more comfortable water use every day.
