I learned via another post someone mention dehumidifiers for hearing aids. I saw that Costco sells one at a lower price than competitors I decided to visit My local Costco to ask about it. I was told that they’re for older HA models with disposable batteries, but not for rechargeable units like my Rexton Reach. And yet a lot of product reviews and manufacturer promotional materials claim they are safe for rechargeable units.

Is there something I’m missing?

Edit: forgot some words. Added them for clarification.
