I have a dehumidifier in my basement that I have been keeping at about 75% relative humidity. It seems to be enough to prevent mildew and musty odors. Is this a good setting or should I adjust it lower? What setting do other people use?

We keep ours at 100%, figuring that we want it to pull as much moisture out as possible.

I've always heard to keep it at or under 55 relative humidity to avoid mold and moisture problems. I would think 75 would be a wee bit damp... but every home is different....

And I could be wrong

We have one in our finished basement (split level house - half below and half above grade) and I keep it at 50% RH. It really only runs in the heat of the summer. When it's beautiful and dry out (anywhere up to about 75 with low humidity) the windows are open anyway.

Mine is at 50. Any higher and it just feels too humid. During the Winter I unplug it since it's useless to have it running then. Mine drains into my sump pump. The grass outside loves it.

I keep mine at 35-50 dependent on how much rain we get.

we keep ours at around 55% If you have it set to keep the room at 75% humidity, that is too high. You definitely want it to be less than 60..so anywhere between 50 and 55 is good.

Set it to <55%. It might be worth investing in a hygrometer for building materials so you can see if you're building materials are above the recommended moisture levels. Moisture is the best way to deteriorate building materials and structures.
