The Best Guitar Humidifier

Need a humidifier for your acoustic guitar? I've used many over the years on a variety of acoustics but Oasis OH-1 is about the best thing going in terms of safety, simplicity, effectiveness, and price. The Oasis checks all the boxes for me.

I've used the OH-1 for two winters and have experienced no leaks at all and my Martin OOO is in great shape even though our indoor humidity is hardly ever above 22% around here.

The  only possible improvement might be a slightly larger water tank -- as it is right now I need to refill about once every two or three days; once per week would be about perfect.
