It has been a hot humid summer for most of us! That means hearing wearers should be more vigilant about keeping their hearing aids dry. Although hearing aids nowadays are moisture resistant, none are completely waterproof. For those with disposable batteries, open the battery doors at night and place them in an open air dry area. For all wearers, both with disposable and rechargeable units, consider using a hearing aid dehumidifier several times a month to further protect your investment. Clean and dry. Maximize your good buy!
