What diameter exhaust hose does it come with? How long can it be extended? Can I get a hose extension?Updated a year ago

TOSOT portable air conditioner includes an exhaust hose with a diameter 5.7 inches and can be extended to 4.9 ft.

We don't have an extension hose for the portable air conditioner. It is not recommended to use a longer hose to vent the hot air as it will make more heat emitting to the area which will affect the cooling performance.
