My neighbor thinks her knee pain is related to humidity.
To test that theory, I looked into dehumidifiers.
But I'm hopelessly confused. *About the only specs I find
are "pints/24 hours removed". *Under what conditions?
The "buyer's guides" talk about conditions ranging from wet
to extremely humid.

I'm looking to take air at 68F from 65 to 40 percent RH or thereabouts.
Looking at some of the engineering data suggests that the dew point is
very low and it'll
be a LOT harder to do that than to get from 100% to 80% on a 95F day.
Outside temp is 45F or so this part of the year. *The house is pretty
"tight".

What are my options to construct an experiment?
She has central air, so I could alternate between heat
and cooling???? *But that sounds like a lot more cooling
than dehumidifying.

Ideas?

Related to humidity -How? Worse or better when humidity is low/high???
