Full product details
Read the full description
A 20" Jumbo carbon block from Waimana for bigger homes and busier water use. It reduces chlorine, taste and odour and catches fine sediment, using activated carbon around a polypropylene core, for cold water at 5–45°C.
Most homes want the 5 micron 20CTO05. It's rated at 75 L/min, plenty for a busy household, and it's the carbon block for Waimana Waiora Ultra UV systems. Choose the 1 micron 20CTO01 for a finer final stage, or the 0.5 micron 20CTO-UF for the finest filtration in the range. Whichever grade you pick, change it every 6–12 months, and a sediment filter ahead of it helps the carbon last longer.
Waimana is an Auckland company, and we're NZ owned in Te Rapa, Hamilton. If it's not right, we'll put it right.
