A reader asks:

I am thinking about using a home purifier with a negative ion generator. The purifier releases about 1 million ions per cubic centimeter. This dose is much less than the therapy product you recommend, which gives off about 100 trillion ions per cubic centimeter. Since there is a lower dose measurement for this home air purifier, does the use of antidepressant meds make a difference — even if I leave the generator running 24/7?


It’s probably not a concern.
