This dry kit helps keep your hearing aids free of moisture.
Resound dry kit
The Resound dry kit removes moisture from your hearing aids by placing them in this container with silica gel crystals. After about 3 months the crystals change from an orange colour to a dark green. At that point they are filled with moisture. The crystals can then be rejuvenated by placing them in the microwave or heating them in the oven. Once dried out they will go back to their orange colour and can continue to be used.
