The NewAir AF-310 is an affordable, energy-efficient evaporative air cooler that’s designed to fit in small spaces. It also has a handful of convenient features and is highly portable.
This portable swamp cooler has an airflow rating of 320 cubic feet per minute (CFM), so it can cool an enclosed area of up to 100 square feet. While it can’t cool large areas or outdoor spaces, both of which the Hessaire MC18M can handle, it can lower the temperature by up to 20 degrees in a small bedroom, living room, kitchen or office.
The AF-310 uses less electricity than some household lightbulbs – just 80 watts. This makes it a cost-effective way to cool a room without running a traditional air conditioner, which requires much more energy. However, the equally capable Luma Comfort EC45S is even more efficient than the NewAir AF-310, using just 45 watts. You can expect to spend around $7 to power the AF-310 over the course of three months during the summer.
This NewAir model has the smallest water tank of the units we compared – only 1 gallon. However, a water-level detector lets you know when you need to refill the tank.
The AF-310 includes several features not all portable swamp coolers have, including an optional ionizer that can clean the air in your room. However, ionizers produce small amounts of ozone, which can harm the environment, so cleaner air has tradeoffs.
This unit also has a three-speed fan and a programmable timer. In addition, the tower oscillator can rotate up to 60 degrees to evenly distribute cool air throughout the room. You can use the included remote control to turn the unit on or off, adjust the blower speed, set the timer, start and stop oscillation, launch ionization, or turn off the water pump to run the cooler as a traditional fan. The remote works within a 19-foot range of the cooler.
The AF-310 weighs only 11.6 pounds, which makes it one of the lightest portable evaporative coolers on the market. It measures 34.5 x 12.63 x 11.38 inches, and its tall, slender frame, coupled with its sleek black and silver casing, make it inconspicuous in a home or office. The unit’s top face houses a control panel with buttons and indicator lights. NewAir offers a one-year warranty on the AF-310, the same as other portable evaporative coolers we looked at.
