The N60 blocks are an essential element in keeping compact Hong Kong living rooms from smelling like a stable. In low-ventilation high-rises combined with local tropical humidity, waste odors compound incredibly fast. Cheap chemical perfume blocks can cause sensitive felines to shun their boxes entirely, but these plant-based blocks target and eliminate volatile sulfur and ammonia molecules directly. Our sitters step into sealed apartments all the time and find the air remarkably crisp, a testament to how well these small cubes perform.

Engineered exclusively for the internal air-duct and waste compartment of the Purobot automated litter box series. Utilizing a 100% natural plant-extract formulation, the N60 block is entirely safe and non-irritating to a cat’s sensitive sense of smell and respiratory tract. Instead of merely masking odors with heavy artificial fragrances, it actively captures, targets, and chemically neutralizes volatile odor compounds like ammonia and hydrogen sulfide. Paired with the machine's dual-odor extraction system, it guarantees your living space stays entirely fresh and odor-free, even when waste is stored for up to two weeks.
