Mr Humfreez

Mr Humfreez by ANZ Bank is a household device that shows New Zealanders if their home is too damp or too cold. Instead of a plastic gadget, it’s a biodegradable device that doesn't require a power source. Mr Humfreez is scientifically calibrated to WHO guidelines for a healthy home. His hygroscopic horns are programmed to uncurl when humidity rises above 65%. Bespoke thermochromic ink on his face turns blue when the temperature dips below 18°C.
