Evaluating a larger diameter filament to help customers in particularly dry environments, as an alternative to purchasing a second reservoir.
No change. Since adding 3% hydrogen peroxide to the tap water and distilled water samples, the mold growth has not worsened or reversed. The original samples with distilled water and 1 and 2 cap-fulls of 3% hydrogen peroxide are still free of visible mold. We also have other customers reporting success with adding hydrogen peroxide. We'll continue the test to see if and when this changes.
Pulled white vinegar containers from the overall testing since the filaments were beginning to exhibit mold specks, and due to the odor. Other containers appear to be unchanged from last reporting.
No sign of discoloration. Humidity still reading at 99% RH.
75 hours after initiating the test, the hygrometer continues to read 99%. There is no sign of discoloration yet. The smell of white vinegar is very strong - and it's likely no one will want this as an option. I'll leave the two vinegar containers for now.
I opened the cooler and inserted a hygrometer. A slight odor of the white vinegar was noticeable. About an hour later the relative humidity is around 92%. This is likely the result of 7 filaments being in use at the same time, the cooler volume being smaller and its seal being better than in a Musik Tent enclosure. This elevated humidity should accelerate the testing. Checked a few hours later and hygrometer was up to 97% RH. Later in day, the inside of the cooler has climbed to 99% RH.
In order to test various mold and mildew inhibitors, we filled up 7 containers with 1.5 cups of water each as follows:
