Experimenting with various concentrations of Hydrogen Peroxide between 3% and 12% to observe behavior relative to humidity. The typical off-the-shelf concentration of peroxide is 3%, which is widely available in stores. 12% is the maximum concentration used in this testing, as this is likely the highest that's available online and still fairly safe for handling by homeowners. In the electronics industry, we routinely use ~30% concentrations which I'd consider unsafe for handling by most people.
What I'm observing is that peroxide emits vapor, similar to water vapor emitted from a water source. The redesign to have up to 12 filaments for each device will be tested when the new lids arrive.
