It does remove gasses, and notify you of time to change. We’re working with specialized environmental and toxicology experts on this - we’ll publish detailed instructions before we ship production filters. Since it’s a safety related matter, I won’t provide interim information.

Information on this is spotty. We’ve been discussing with a number of experts. The best estimate we have right now is that tubes lose 5% of their power power per year when used lightly.
We recently tested tubes that we stored for two years and saw negligible changes in power levels, but there was not enough data to be meaningful.
