2.5" x 10" CTO5 (Colour Taste Odor with integrated 5 Micron particle filtration).
 
Reduces content of chlorine, chlorination byproducts, natural organic matter and petrochemicals. Improves colour, taste and odour of water. The replacement filters contain 100% high-quality activated carbon. Lifetime approx. 15,000 L.
 
The filters also reduce particles larger than 5 micron thanks to it's design structure
 
Filter casing is designed in such way that the water flow passes from the bottom to the top continuously loading and increasing the time of water contact with the carbon. So it provides the maximum activated carbon sorption capacity.
