The top portable AC pick for anyone who can't install a window unit. Dual-hose design makes it genuinely more powerful and efficient than single-hose portables.
If your building won't allow window units or you have casement windows, stop fighting it and get the Midea Duo. It's the only portable AC Wirecutter actually recommends without major caveats.
“The Midea Duo MAP14HS1TBL is quieter, more powerful, and more efficient than any other portable AC we've tested.”
