The Honeywell CS10XE is a portable, indoor evaporative air cooler, often called a swamp cooler. It draws warm room air across water-saturated honeycomb cooling media, and as the water evaporates it cools the air. Because it has no compressor and no refrigerant, it runs on very little power, and it also adds some humidity to the room. Honeywell describes it as a 3-in-1 unit that cools, humidifies, and works as a fan.
The CS10XE is built for spot cooling in small to medium spaces: Honeywell's own spec sheet lists a small bedroom, office, child's play room, or dining area. Evaporative cooling works best when the air is hot and dry, so Honeywell recommends a relative humidity of 60% or less and points to dry regions such as the southwestern United States. It is not an air conditioner, and Honeywell's buying note suggests portable or window air conditioners for more humid climates.
Common configuration: 300 CFM (510 m³/hr) of airflow, rated to cool rooms up to 175 sq ft (16 sq m), 102 watts of power consumption, and a detachable 2.6 gallon (10 liter) water tank with a low water alarm. It uses honeycomb cooling media with a carbon dust filter and has oscillating louvers, a remote control with on-board storage, an ice compartment, an auto-off timer (0.5 to 7.5 hours), and caster wheels. Dimensions are 13.5" W x 15.7" D x 31.5" H and weight is 18.5 lb (8.4 kg). Note that listings are not fully consistent: Honeywell's spec sheet lists three speeds (high, medium, low) while its store page lists four including sleep, and one retailer shows a black-and-silver CS10XE at 423 CFM and 258 sq ft.
