8 Air Coolers to Avoid: What Could Hold You Back in 2025

3. Shark FlexBreeze HydroGo-Frequent Refills Required-($173.2)

The Shark FlexBreeze HydroGo is undeniably portable and stylish, perfect for personal cooling on the go. But its tiny 150ml water tank means you’ll be topping it up constantly if you plan to use it all day. Continuous misting lasts only about half an hour, and even the interval mode stretches that to just an hour. For anyone needing uninterrupted cooling in larger spaces or over long periods, this cooler falls short. It works best as a personal, short-term solution rather than a serious room cooler. Also, since it’s more like a misting fan than a traditional cooler, don’t expect powerful cooling effects at a distance indoors.
