CTO 20 BIG SD 10 mcr  - Activated carbon block

The high-quality CARBON-BLOCK made from 100% coconut shells filters contaminants from drinking water:

- Lime flakes
- Taste impairments
- Odour impairments and fine particles
- organic contaminants


Coconut shell activated carbon has an exceptionally high micropore density, which means it can absorb more contaminants per gram. Activated carbon blocks that are made from 100% coconut shells are of higher quality than conventional activated carbon blocks from mass production in China. 

Carbon blocks made from coconut shells are free from chemical additives or binders. Cheap activated carbon blocks from China contain additives and binders that could have a problematic effect on your drinking water.

Due to their high adsorption capacity, coconut shell activated carbon is more effective at removing chlorine, heavy metals, pesticides, organic chemicals, and unpleasant odours.

Our activated carbon blocks made from coconut shells not only offer better filtration properties, but are also more environmentally friendly and sustainable.
