Yep all three of ours do mitigation and build back, but I think they only clean when they have to or for mega square footage
A short length of 2 inch is all you need to plumb the portables exhaust outside.The draw back for me was always unnecessary moisture to the environment. All the "booger" particles, urine odor and high humidity exhaust blown into living space.
I used to hate winter cleanings with portables. Windows fog up and water condenses off the glass.
Can't think a bigger disservice. I'd rather have smeared boogers.
Boogers, who has boogers in there carpet? Fred hopefully you wear shoes at home.
