I've got a pot of water on the woodstove, which brought our humidity in the living room up to about 16%... but I'm sure that the bedroom is still probably single-digit, and my lungs are feeling it! Our trip to humid climates spoiled me! So, I'm on the hunt for two room-size humidifiers. For Guppy, a nightlight is fine. For us, no light is better. Do you have one you love? Something sturdy preferred - a stunning amount of reviews on Amazon say 'broke after one month.' This will undoubtedly get a lot of continuous use.
