I forget it’s even on.

It sits five feet from my bed and I honestly forget it’s running. The room is cool and I sleep through the night.

I’m on video calls all day. My old unit was so loud I had to turn it off for meetings. This one stays on.

Questions Before You Order?

How quiet is it really?

46 dB, about as loud as a quiet library or soft rainfall. Most people sleep right next to it.

How big a room will it cool?

Rooms up to about 350 sq ft, like a large bedroom, home office, living room or studio apartment.

What windows does the kit fit?

The included window kit fits vertical or horizontal sliding windows from 25.5 to 47 in.

Do I have to empty water?

In cool mode most moisture leaves through the exhaust hose. In dry mode or on very humid days, use the bottom drain plug with the included drain hose.

Does it need a special outlet?

No. It plugs into a standard 115 V household outlet. Plug it straight into the wall rather than an extension cord.

How do I clean the filter?

Slide out the filter, rinse it under the tap, let it dry and slide it back in.

What’s the return policy?

Free returns within 30 days of delivery. If it isn’t right, send it back.
