Our takeReal relief in a dry-climate garage, shop or patio with a door open; a damp fan anywhere humid. Hessaire says it loses effectiveness above 60% humidity, and it needs fresh air in and an exit for the damp air.The basic small-room window unit: knob controls, 150 sq ft, CEER 11.0 and a 13 in window opening. Fine for a small bedroom on a budget; louder and less efficient than an inverter unit.

Watch out forThe MC37V is the same cooler with a different control panel and motor; neither has a timer or remote, whatever a listing says. Warranty is 1 year on parts only, excludes pads and labor, and applies only to authorized sellers; the Amazon seller is a third party. Hessaire says pumps can wear out after 4-6 months of use; budget a media set each season.Water sloshing inside is the slinger design and normal per Frigidaire; drilling the base pan voids the warranty. Keep the 5/16 in rear pitch or it leaks indoors; owners report mildew smells in humid weather. Warranty excludes units transferred from the original owner.
