Our community has rated this post as helpful. If you agree, why not thank

IMPORTANT: From looking at the photo and diagram on Amazon, this is almost certainly a single hose portable air conditioner. BAD DEAL AT ANY PRICE.

Why does anyone keep making this garbage product? You pay for the electricity to cool the air, then you throw your cool air out the window, to be replaced with hot air from outside. Which needs to be cooled again. It makes the window air conditioners look positively decent (where the inside cooling and outside heat exchange are separate.)

Holy crap 65db is the low noise? What's the loud setting? This would be like having the worst dishwasher ever in your bedroom doing its thing.

Single hose units don't throw cold air out the window, they only exhaust the heat out the window; they draw air in from the back of the unit which is inside your room rather than drawing in air from outside your window. The one advantage to drawing in air from the outside is that you create a slight positive pressure in the room, if the door is closed, which can help keep the hot air from the rest of the house entering through your room door and power outlets. WIndow AC units will always be more efficient and consume less power, but if you can't use one, these portable AC units help a little.

The one thing you should worry about with hoses, is wrapping them with insulating tape or foam, to prevent the heat from the hose radiating back into your room before it makes it out the window.

Obligatory Technology Connection video regarding single hose portable AC
https://www.youtube.com/watch?v=_-mBeYC2KGc

TLDR: with these single hose portable AC, you cool the air in the room, then suck that cooled air to cool the condenser part of the AC then dump it back outside (also suck in warm air through all the cracks and crevices of the room). Also the loudest part of the AC, the condenser, is now inside your room.

I learned my lesson the hard way. Switched from a single hose to a window unit and it's night and day!
