what PACIFIC months do you run a dehumidifier in the basement?

*Specific*

Don't you mean SPECIFIC? It needs to be run during humid months, for example, here in Florida it would be during the summer, but I run mine 12 months out of the year.

You can run a dehumidifier year round in a basement. Set it fo 45 to 50 percent and let it run

The Pacific is an OCEAN.
You run a humidifier/dehumidifier YEAR ROUND. If it is set properly, it comes on when the humidity NEEDS changed.
