Evaporative air coolers are a triple threat of cooling solutions—they’re effective, energy-efficient, environmentally-friendly, and they even .
Air coolers create a comfortable, cool breeze with the natural process of water evaporation. And, they work in and out of your home. Keep cool at your desk, stay comfy in your living room, or lounge outside on your patio.
However, air coolers are a little different from air conditioners; they work best in drier climates and require cross ventilation to circulate fresh air.
To help you get the most out of your cooler, we’ve compiled these handy tips.
Pair with Dry Air
Managing your home’s humidity levels is a key component to comfort. It helps your home feel cool in the summer and warm in the winter. During summer heat, humidity makes the air feel warmer and muggier. For more, check out our humidity guide to get the perfect balance in your home.
Indoor air coolers work best in climates with a maximum relative humidity of 50% or less. Warm, dry air means higher evaporation, which brings the greatest temperature decrease.
Air coolers also boost the humidity in a space, so indoor coolers are perfect for maintaining a cool breeze and increasing comfort in arid weather.
Outside, humidity has less of an impact on air cooler effectiveness. An outdoor air cooler will work best in drier air, but even in moist air, it’s a welcomed cooling solution that provides better cooling than a fan without evaporative cooling technology.
Summer BBQs and backyard hangouts will be much more comfortable with an evaporative cooler reducing the warm air a few degrees compared to a fan or natural wind that just blows warm air around.
Place Near an Open Window to Cross Ventilate
For optimal performance, evaporative air coolers require airflow from open windows or doors. The cooler pulls in outside air and pushes the stale indoor air out. This keeps the indoor air fresh and cool while reducing humidity collecting in the room. This fresh air is why the CDC and the EPA both recommend evaporative coolers as a safe way to stay cool during the coronavirus pandemic.
As shown below, the best place to put an air cooler is near an open window. The cooler can draw in fresh air and circulate it in the room before exiting via another window.
However, you may need to experiment to find the right combination of open windows/doors and the cooler's positioning to keep the air flowing best.
Use Ice for a Cool Blast
For a boost, add ice to your water tank. Some models like the Honeywell Indoor Portable Air Cooler CL30XCWW come with a top-loading ice compartment for easy refills. Others come equipped with reusable ice packs like the Honeywell Indoor Tower Air Cooler DLC203AE.
Place Yourself in the Air Flow
For the maximum cooling effect, strategically place your air cooler so that the cool air blows directly towards you. Unlike an AC where the cool air hangs in an enclosed room, an air cooler circulates the air in-and-out of the room. To get the most airflow, you need to be in the stream.
Honeywell air coolers are portable and quickly move around your home as needed. They’re a snap to set up in the best spots for direct airflow to your body.
Plus, Honeywell has airflow options that cover every situation. For spot cooling, the newly launched Honeywell Zeta™ will cool a personal space like your desk or bed. The Honeywell CO610PM will cool an entire room with airflow felt up-to 33 feet away.
Get the Right Cooler for the Space
Air coolers cover up-to a certain sized area; stay within the range for the best results. After all, you can’t expect a mini cooler to cool a giant room, right? Before shopping, get the square footage of your space, so you know what coolers to look at. Note: portable air coolers cool one room at a time.
Also, know that the manufacturer’s recommended coverage area assumes optimal environmental factors from humidity, to cross ventilation, to your position within the airflow. The cooling effect can also drop if more people enter the room.
Lastly, the right cooler should reach you, whether you’re sitting or standing in order to feel the cooling sensation of the moist breeze. If you need higher reach, Honeywell Tower Coolers like the TC50PEU or DLC203AE, aim the air high so the airflow will reach over furniture.
Perform Basic Maintenance for Long Lasting Cool
Our range of air cooler models come with convenient features to make maintenance easy, including low water alarms that alert when to refill, easy-to-clean detachable tanks, and continuous water supply options for long unattended cooling.
The honeycomb cooling pads in the air cooler should be cleaned at least once a month with lukewarm water and a mild detergent to avoid dust, dirt, mildew build-up. For full maintenance details, see your unit’s manual or check out this article for more cleaning tips and tricks.
