To answer your question Ozblue, you're correct. Nowhere does it...

To answer your question Ozblue, you're correct. Nowhere does it specifically say ambient air OH radical. However as mentioned HC is not the only media to discuss stocks. Even if they couldnt take the moisture from relative humidity in the air, then it would be a simple matter of having a small water drip feed. They state OH radicals in occupied rooms and feed gas is ambient air. So you can invest how you like but your research on one small statement that stops you from investing, good luck
