The large capacity of Type B silica gel absorbs not only excess moisture from futons and beds but also unpleasant odors such as ammonia, which is the source of sweat odor. Furthermore, the moisture-regulating function of Type B silica gel inhibits the growth of dust mites and mold, allowing you to spend the rainy season comfortably. [Rechargeable Type & Reusable Moisture-Proof Sheet] Type B silica gel can be easily regenerated by simply drying it in the sun after absorbing moisture, making it economical for repeated use. Also, it comes with a moisture sensor, so you can see the moisture absorption status at a glance. [Moisture Sensor Indicates Drying Time] The dehumidifying sheet is equipped with a moisture sensor. When the moisture absorption capacity of the dehumidifying sheet approaches its limit, the color of the sensor part changes from blue to pink (light white), indicating it's time to dry. The moisture absorption capacity is restored when dried in the sun. [Washable Dehumidifying Sheet & Hygienic] Many people want to wash their dehumidifying sheets repeatedly, especially during the season when they are concerned about night sweats! Our dehumidifying sheets use a material that is compatible with water washing. Since the dehumidifying sheet is "machine washable using a net," please consider it if you are concerned about cleanliness. Please remove the sensor when washing. [Lightweight & Thin & Versatile Dehumidifying Mat] Despite its high moisture absorption capacity, it is a lightweight dehumidifying sheet. It can be easily carried by women and the elderly. It is thin and light, so it can be used under mattresses and futons, on the floor of closets, etc. $$1999 m1,074
