Thoughts on these levels ?
Hi all. We usually keep the basement windows open just to get some fresh air because we work out maybe 3 to 4 hours weekly. Have a walk out basement. it was so humid, turned on the dehumidifier and shut the windows. Levels are much higher in the last two days since I did that.
Even with the windows closed in the winter, it wasn't as high. I have a Boiler in the basement, not sure if that affects it or not.
