Cintropur Activated Carbon – 3.4 litres

Coconut shell-based, highly efficient granular activated carbon for Cintropur technology. Delivered in a 3.4 liter bag (new recyclable PMD packaging) - equivalent to approx. 6 refills for NW 25 CTN, 3 refills for NW 280 CTN, 2 for NW 32 TE and 1 for NW 500 TE. Ideal for taste, odor and reduction of chlorine and selected micropollutants - with low pressure drop, high flow rate and easy maintenance. ♻️💧

Summary
Cintropur Activated Carbon is a premium, coconut-based GAC medium developed for CTN cartridges and TE units in the Cintropur range. The porous microstructure provides a very large internal surface for adsorption of unwanted substances, while Cintropur's own flow-through geometry ensures a long contact time (better effect at lower water velocity). The bag's volume of 3.4 liters is designed for practical refills in homes and businesses - and the reusable CTN cartridge makes the solution economical and more environmentally friendly over time.

Health effects
• Contributes to a better drinking experience by reducing odors and tastes caused by chlorine, organic compounds and ozone.
• Can reduce levels of selected pesticides/herbicides, VOCs (volatile organic compounds), THMs (trihalomethanes) and some PFAS components, depending on water quality and contact time.
• Preserves the water's mineral balance and does not significantly affect pH.
• Chemical-free treatment – ​​no additives in the water and no by-products from the process itself when used correctly.
• Low pressure drop and high capacity provide a stable supply to the entire house when pre-filtration (sleeve/cloth) is in place.

Top features and a lesser known effect
The most requested effects are improved taste/smell and reduction of residual chlorine in mains water; in addition, the ability to address a number of micropollutants in well and rainwater is valued (assuming proper pretreatment and contact time). Less well known is that lower flow rates often result in better adsorption (longer "EBCT"/contact time), so that you can sometimes get noticeably better results by tapping more slowly.

Technical details and specifications
Product: Cintropur Activated Carbon (GAC), coconut-based
Article number: FWVACT001
Volume: 3.4 liters (granules) - recyclable PMD bag
Compatibility/refill: approx. 6× NW 25 CTN (0.57 L each), 3× NW 280 CTN, 2× NW 32 TE (1.7 L), 1× NW 500 TE
Recommended use: After mechanical pre-filtration (sleeve 100–25 μm, possibly finer if necessary)
Area of use: Taste/odor, residual chlorine/ozone, selected organic micropollutants (VOCs, THM, pesticides/herbicides, some PFAS)
Operation and maintenance: Rinse the granulate in clear water before commissioning. Change interval 3–6 months for domestic use (varies with water quality/consumption). Lower flow gives better effect.
Hygiene: Container/CTN is rinsed with each media change. Keep the system depressurized and follow Cintropur's service procedure.
System integration: Can be combined with Cintropur DUO/TRIO (pre-filter + carbon + UV-C) for comprehensive treatment. UV steps are always placed last in the line.
Environment: Reusable CTN cartridge reduces waste; bag is designed for easy refilling and PMD recycling.
Important: Water is only classified as "drinking water" when both microbiological and chemical parameters meet relevant standards; activated charcoal mainly addresses taste/odor and adsorbable substances - it does not disinfect.

Disclaimer and disclaimer (for appliances and hardware)
Use and maintenance are at your own risk and must be carried out in accordance with the manufacturer's instructions. Effect is affected by raw water quality (turbidity, TOC, iron/manganese), pretreatment, flow rate and contact time. Always combine with suitable pre-filtration; consider UV disinfection where microbiological quality is uncertain. Keep out of the reach of children. Uno Vita AS does not claim that our products can cure disease, regardless of any research that suggests benefits.
