I don't know if this is the right place to ask this...

I keep a 30 pint de-humidifier running all the time in our coach while parked at home. My question is...I set it at 65%, is this ok or do I need to adjust up or down? Just a note, at this setting it does cycle on and off.

We live on the edge of the Olympic Mountains Rain Shadow, mild temps and about 15 to 18" rain fall each year.

According to the EPA,

The ideal levels of humidity for your living space will be less than 60% in the summer and between 25 to 40% in the winter.

I am guessing you are somewhere near Squim which is in or near the rain shadow. Being so close to both the rainforest and sandwiched between the ocean and Puget sound I would think that it would be hard to lower the humidity much below 65% even in the rain shadow.

I would think that to be an acceptable level as long as there is good air circulation. You could try a lower setting but it may cause the unit to run continuously.

If you are in Sequim, then I'd think that would be a pretty reasonable level. I'd want to keep it above 50% just because you live in a damp climate and don't want to dry out all of the wood too much. That should be low enough to prevent mold.

Thanks for the input...I adjusted it down to 60%. I also have a heater in the coach set at 40 Degrees and a 200 watt ceramic heater in the basement near the HWH and the wet bay set at 45 degrees. AND if it gets below freezing, which seldom happens in our area, I'll turn on the heating pads for the tanks.

Yes, we live on Discovery Bay looking West toward Diamond Point and Protection Island.

Again, thank much...Always fine tuning.
