To cool down your space easily, the
best portable air conditioners without a hose are technically not air conditioners at all, since the hoses are necessary for getting rid of the heat and humidity pulled by an air conditioner. However, vent-free coolers — also known as swamp coolers and evaporative coolers — are an easy way to bring down the temps. But since these units use a fan along with water or ice to operate, they tend to work best in low humidity, so they're best suited to those who live in drier climates.
When shopping for a cooler, be sure to note its tank size and how much water your cooler can hold. Having a larger tank will help it operate effectively for an extended period but will also take up a lot more space and be heavier to move. You'll also want to investigate how many square feet your cooler can handle, and if it's best suited for spot cooling, small rooms, larger areas, or outside. Features for added convenience include remote controls and timers. When it comes to outdoor models, some even hook up the a garden hose so you never have to worry about the tank going empty. So consider which ones make the biggest difference for you.
evaporative coolers will help keep you and home cool and comfortable from the heat while also keeping energy bills low whether you're looking to cool the area around your desk or a whole home.
