Flow Med Dry-Cap UV 4 Hearing Aid Dehumidifier

dry-cap uv 4® Smart Hearing Aid Dehumidifier & UV Sanitizer

The dry-cap uv 4® is a smart dehumidifier and UV sanitizer for hearing aids, built to combat moisture, earwax, and body oils — the leading causes of hearing aid malfunction. It's designed for anyone who wears a hearing aid, cochlear audio processor, or in-ear monitor, regardless of brand, and works with both rechargeable and battery-powered devices.

Important Compatibility Notice

The dry-cap uv 4® works with virtually all hearing aid brands and charging stations. The open drying chamber (144 x 82 x 96 mm) accommodates charging stations positioned centered underneath the unit or behind it with the flap open. This device dries, sanitizes, and can trickle-charge hearing aids via its USB-C output, but it is not a hearing aid charger itself. You'll still use your existing charging cradle inside the chamber. If you're unsure whether your charging station will fit, contact us before ordering.
