Protecting your hearing aid from the everyday environment

Hearing aids are delicate instruments, but they must work consistently whether they are indoors or outdoors and despite exposure to dirt, moisture, changes in temperature and humidity, earwax and skin oils. Now Beltone is using the latest in nano-engineered protection to protect your hearing aids against the harmful effects of the everyday environment.


Beltone’s HPF80 NanoBlock protective coating is the same technology that Nike® and Adidas® use to protect their athletic gear and that many major electronics firms use to protect their mobile phones and MP3 players. Applying a very thin (nanometre) layer of polymer to the entire hearing instrument, rather than a thicker layer of spot coating in selected areas, significantly improves the protection provided. This, in turn, helps reduce both the need for and the additional cost of professional cleaning and repairs, giving you more time to hear and enjoy the world around you.

How does HPF80 NanoBlock work?

Beltone's HPF80 NanoBlock coating actually helps repel harmful moisture and particulates. This coating is molecularly bound to the entire hearing instrument at a nanoscopic level so the two become inseparable. In fact, this layer of protection is a thousand times thinner than a human hair, making it completely invisible to the naked eye.

How will HPF80 NanoBlock benefit you?

Our HPF80 NanoBlock coating helps you protect your investment, meaning you'll spend less time maintaining and cleaning your hearing instruments and more time enjoying them. Plus, you won't have to worry about working up a little sweat. With Beltone's HPF80 NanoBlock, sweat and moisture bead right off, and dirt, dust, and earwax can be simply wiped away. Caring for your hearing aids is easier than ever.

At Beltone, we've been committed to advancing the science of hearing care since 1940. HPF80 NanoBlock is just the latest of our breakthroughs in design, performance and comfort.
