50. When it goes over that. I feel sick.

+1 We have the same set up. Our stand alone dehumidifier is set to 50% and it's about that upstairs. It makes such a huge difference.

That's probably a tiny bit high. It's usually said that 40 - 60% is optimal for both comfort and for furniture. You can usually reduce humidity levels with room dehumidifiers, or with a whole-house dehumidifier, but the older and leakier the house the harder it will be to impact and the more energy it will take.

I think “unhealthy” is a little extreme.

umm, it creates an environment for mold. google it.

53 in our 70+ year old rowhouse. Temp is 76, but set to 77 (hasn't come on yet today)

75%+ its insane. Gives me a migraine.

We set our thermostat to 52% humidity as a target. It's usually right around 50, but on really hot days like today the AC runs extra to get to 52%. I start to really notice it if it's over 58% - the air just feels thick to me.

Mine gets as high as 80% at times in my garden level apartment. I have a good Frigidaire dehumidifier which can knock it down to 50% in about an hours time - it’s just amazing to me how much water it takes out of the air.

Normal.

When it’s this hot, I stay down about 50. The worst is when it’s humid but cool, so the a/c doesn’t run as much.

Thanks.

We have a dehumidifier on our main floor right in front of the main return vent and its a struggle to keep it under 52% I hate humidity.

Normal

I'm seeing 63% and I'm wondering if that's high or normal for the area.

Thanks.
