Hello,
I'm selling my Echoflow Wave 2. It was just purchased in April 2024 for $1,435. I'm selling it for $1000. It works great for smaller areas such as a tent while camping, car, truck and even a small room.

I purchased it for my truck but no longer need it. It's great to have as a back up, just in case the electricity goes out at home or to have an option while camping, fishing, or at the beach to stay cool.

It also has a built-in heater and all runs off of a rechargeable battery. The battery takes two hours to charge from 0% to 100% and lasts for 8 hours on economy mode or 4 hours on continuous mode.

It comes with two durable hoses that connect directly to the machine ( one to bring in fresh air and one to push out hot air.

This unit also comes with a window sleeve that you attach to the hoses if need be.

I've registered the unit and the add on battery, so their both under a manufacturer warranty.
