Maintenance is surprisingly minimal with Neutralox. The UV bulbs need replacing roughly every 12,000 hours, and the carbon catalyst, engineered for longevity, requires a change approximately every 18 months. General upkeep, including lubricating bearings and cleaning out fan windings, is straightforward, amounting to just 1-2 person-days per unit annually. This minimal effort ensures your system runs smoothly, providing consistent odour control without the hassle.
