【Eliminating refrigerator odors】 Refrigerator deodorant uses physical deodorization, contains no chemicals, leaves no residue, and does not affect the freshness of food. The refrigerator deodorization device can efficiently purify the air in the refrigerator, quickly remove refrigerator odors, and last for a long time, freeing your refrigerator from bad smells. The reusable refrigerator deodorant is more economical than baking soda and charcoal bags, and does not require long-term replacement of refrigerator deodorant. 【Long-lasting freshness】 Extend the storage time of food, making it fresher, more nutritious, and healthier. During storage, vegetables, fruits, meats, and grains produce various ripening substances that accelerate food ripening, aging, and spoilage. The refrigerator deodorizing and freshness preserving machine can decompose these ripening substances, delaying food aging and spoilage, thereby maximizing the freshness of ingredients. 【Economical and Practical】: The refrigerator deodorizer is equipped with a 5W deodorizing bulb. There is no need to replace high-cost filters. To ensure optimal effectiveness, we recommend replacing the fridge deodorizer bulb every 6-8 months.
