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.

Central air IS a dehumidifier that also cools.

A store-bought dehumidifier is basically a window A/C brought inside, except
neater, and with a net heating effect.

I believe a heat pump will also dehumidify.

So you will need a HD-type dehumidifier only in the winter, and then not all
that often.

There is proly some limbo-temperature where you would conceivably want to
run the A/C, and then also run some heat.

I have found the HD jobbies to produce prodigious amounts of water, and be
pretty reliable. *A friend's Sears went kaput right away, one of my HD's
seems to be acting up, but 2 others are still good after a few years.

Regarding knee pain, as rainsley pointed alluded to, diet and exercise can
be a big factor.
Diet no-no's: *any food sensitivities, crap like orange soda's (Slice,
Fanta, et al) with boucou artificial flavors/colorings, etc.
A rice-based diet is an excellent core diet. *Add peripheral foods as
required.
Yes-yes's: *gluscosamine, chondroiten, msm.
More yes-yes's: vits A, E, C, and always always a good multi (Kirkland
Mature multi is good, no iron). *Also has a decent glucosamine formula.

Yes yes yes yes yes: * suitable exercise, hyperflexion of the knee (for
some), and often inversion.

The Haier HD unit I got last summer and returned put out half is rated
output, I guess I wasnt lucky on that one but verifying output in this
day an age of cheap import junk is important
