I have a fleet of these Ideal-Air humidifiers, two smaller 75 pint units for a 10'X18' grow room. No one sells replacement parts. Hawthorne has not been helpful. You will end up dismantling them to clean them frequently because they grow slim in the holding trays. eventually the float valves develop indented spots and don't shut off very well.   Im experimenting with the House Of Hydro ultrasonics and find them better so far. Have you checked out the Mycowizard video with the Australian humidity control module and Hart high pressure humidifier? Id like to move in the direction over time.

Yes, I agree with Dakota. I  really love the videos; I didn't notice the balance between background audio and foreground yabbering unbalanced as much as the general mastering isn loud enough. a bit more volume on the audio would be helpful;Im maxing out my laptop volume and still leaning in to hear.  I work with a number of bouncy house fans for FAE and the background noise of those bright green suckers makes it a bit difficult to hear the audio on the videos.
