If humidity or wet weather has caused your home or office to feel muggy and damp, then DampRid Moisture Absorber is a smart solution. The DampRid Refill, 42 oz, is an easy-to-pour refill for DampRid containers. It can also be used in any brand of non-electric moisture trapper. The 42-oz container can refill your DampRid moisture absorber around four times. The package seals with an air-tight closure so that moisture cannot get into the bag, thus keeping the formula fresh and ready to use. The DampRid Moisture Absorber is also an excellent way to prevent mold and mildew that can result from humidity or dampness in the home.
