When the temperature in your office is hot, it’s pretty hard for your mind to stay cool. Having a powerful cooling system in the office is important if you want to get work done. There’s just one problem: you don’t have a window for putting an AC unit in.

If you’re looking for the best portable air conditioners without a hose, we have some good news and some bad news for you. We’ll start with the bad news: there is no such thing as a ventless air conditioner.

The good news is, there are portable cooling systems that work perfectly without a window. While they’re not air conditioners, these ventless coolers can effectively cool your office and make the temperature tolerable for you and your coworkers.

These cooling systems are called evaporative coolers (sometimes known as swamp coolers). To help you beat the heat, we created this list of the 12 best portable AC-like coolers without a hose.
