The Honeywell CO48PM is a commercial portable evaporative air cooler designed for both indoor and outdoor use. Evaporative air coolers like this model use ice to lower air temperature. When filled with ice, a fan blows enough air to cool about 600 square feet. If you want a reliable air cooler at an affordable price, this is an attractive model that will probably meet your needs.

Performance and Features

The Honeywell CO48PM is designed to cool rooms measuring about 600 square feet. It can also lower air temperatures outdoors. The cooler has a versatile design that lets it work unattended for several hours. Owners can connect the air cooler to a water supply to keep it filled with ice, or they can add ice manually as the supply runs low. Its overflow protection catches excess water as the ice melts.

The CO48PM has a three-speed fan with 14-inch blades. The unit has cooling media on three sides, allowing it to cool temperatures quickly and evenly, even in stuffy rooms. This type of system works best in dry climates because it adds moisture to the air.

Since the cooling unit does not use a compressor system, it uses minimal electricity. Relying on an evaporative system also keeps the unit’s weight down. The Honeywell CO48PM weighs less than 30 pounds and measures 14.8 x 24.4 x 34.2 inches. Caster wheels make it easy to move from room to room.

This is an extremely usable portable air cooler. Weighing less than 30 pounds makes it easy to move. It has a six-foot power cord that helps owners position it in low-traffic areas. It also has a continuous water supply connection for those who wish to use it for long periods of time without refilling the ice tank. The fan’s 14-inch blades help make this unit appropriate for cooling areas under 600 square feet in size.


The Honeywell CO48PM makes about as much noise as the average box fan. Since it does not use a compressor, it does not make loud noises like most air conditioners. The CO48PM cools rooms effectively without creating disruptive sounds. The slight noise that it does make quickly blends into the background.

Energy Consumption and Warranty

Evaporative air coolers like this Honeywell CO48PM use considerably less energy than regular air conditioners because they use non-compressor systems that cool the air naturally. Instead of relying on electricity to cool the air, this design uses ice from the refrigerator to lower the air’s temperature. The device only needs electricity to operate the fan that mixes cool air into the room.

The CO48PM comes with a one-year limited warranty that pays to repair or replace defective parts. Honeywell, the manufacturer, does not honor warranties for air coolers that have been used in ways other than intended. Using one to cool a room larger than 600 square feet, for instance, could invalidate the warranty.

Why Honeywell CO48PM?

The Honeywell CO48PM is a highly rated portable air cooler that will meet the needs of most commercial and residential owners. The option to manually add ice or connect the system to a water supply makes it more versatile than some models. The low weight and casters make it extremely portable. Anyone who wants to cool an area of 600 square feet or less should consider this unit. If a typical box fan doesn’t cool your rooms well enough, but you don’t want the noise of a portable air conditioner, you should consider buying this air cooler. It’s one of the best options for the price.
