A water ozonation system that receives source water from a water source and converts it to ozonated water for use in a washing machine, the water ozonation system comprising: a system body that receives the source water from the water source; an ozone generator that is configured to generate ozone, the ozone generator being coupled to the system body; a sensor assembly that is coupled to the system body, the sensor assembly being configured to sense at least one ambient environmental condition and generate at least one electronic data signal based on the sensed at least one ambient environmental condition; and characterised in that the water ozone system further comprises: a controller that receives the at least one electronic data signal from the sensor assembly and regulates a level of ozone that is generated by the ozone generator based at least in part on the at least one electronic data signal; wherein the sensor assembly includes an air humidity sensor that senses an air humidity of ambient air to determine if the ambient air should be dehumidified prior to being directed into the ozone generator, and generates a first electronic data signal based on the sensed air humidity; and wherein the controller regulates the level of ozone that is generated by the ozone generator based at least in part on the first electronic data signal. a system body that receives the source water from the water source; an ozone generator that is configured to generate ozone, the ozone generator being coupled to the system body; a sensor assembly that is coupled to the system body, the sensor assembly being configured to sense at least one ambient environmental condition and generate at least one electronic data signal based on the sensed at least one ambient environmental condition; and characterised in that the water ozone system further comprises: a controller that receives the at least one electronic data signal from the sensor assembly and regulates a level of ozone that is generated by the ozone generator based at least in part on the at least one electronic data signal; wherein the sensor assembly includes an air humidity sensor that senses an air humidity of ambient air to determine if the ambient air should be dehumidified prior to being directed into the ozone generator, and generates a first electronic data signal based on the sensed air humidity; and wherein the controller regulates the level of ozone that is generated by the ozone generator based at least in part on the first electronic data signal. a controller that receives the at least one electronic data signal from the sensor assembly and regulates a level of ozone that is generated by the ozone generator based at least in part on the at least one electronic data signal; wherein the sensor assembly includes an air humidity sensor that senses an air humidity of ambient air to determine if the ambient air should be dehumidified prior to being directed into the ozone generator, and generates a first electronic data signal based on the sensed air humidity; and wherein the controller regulates the level of ozone that is generated by the ozone generator based at least in part on the first electronic data signal.
