The FZ-G30DF deodorizing filter incorporates high-density activated carbon to strongly absorb and decompose odors such as cigarette smoke, pet odors, and household odors. It achieves a deodorization rate of over 92.5%, keeping the indoor air cleaner and fresher. The FZ-G30MF humidifying filter has excellent water absorption and is antibacterial. It maintains a stable humidity during humidification operation while effectively suppressing the growth of 99.0% of bacteria and mold. By using the three types of filters in combination, a triple effect of high-efficiency purification, powerful deodorization, and healthy humidification is achieved. The filters are fully compatible with the corresponding models, have clear directional markings, and can be easily replaced without tools.
