The easy-to-use PerfectDry Lux dries and sanitizes hearing aids in just 45 minutes. UV-C light kills 99.9% of germs, bacteria and fungi. Daily use results in improved acoustic performance, better reliability, and better ear hygiene. Please note if you wear behind the ear hearing aids with moulds we recommend selecting the Global dry and Store drying system as your hearing aids may not fit in the PerfectDry Lux.
