Replacement filter cartridge suitable exclusively for the Veluda TF-1 water filter. The filter material is granular carbon and calcium sulfite. The activated coconut granular carbon effectively removes radioactive iodine, chlorine, trihalomethanes, and harmful chemicals. 

Calcium sulfite removes chlorine and heavy metals such as lead, mercury, cadmium, and aluminum 100 times more effectively than activated carbon. It is recommended to change the filter every 3-9 months or 350 liters depending on usage.
