Abstract：Refrigerator odor is a key issue affecting user experience and food preservation.To address the inadequacy of traditional methods in real-world scenarios,aimed to empirically compare the actual efficacy,user experience,and safety of three deodorization technologies:compound bio-enzymes,activated carbon,and ozone generators.Seventy-five households were recruited and randomly assigned to three groups for a four-week field test.Data were collected via odor intensity scales,user satisfaction,and safety questionnaires.Results showed that the compound bio-enzyme group achieved an 81％reduction in odor score,the ozone generator group 72％,both significantly outperforming the activated carbon group(39％).The bio-enzyme group led comprehensively in satisfaction(4.5/5.0),perceived safety(4.8/5.0),and convenience(4.9/5.0).While the ozone generator was effective,it received lower ratings for safety and convenience(2.9/5.0).It is concluded that compound bio-enzymes offer a safe,efficient,and imperceptible solution for daily use,whereas ozone generators are more suitable for rapid emergency treatment,and activated carbon technology shows limited effectiveness.Provides direct user-experience-based evidence and selection criteria for optimizing deodorization functions in the home appliance industry.
