Product Description

Evaporative cooling fans are designed to pull hot, dry air through a water-soaked media filter using a water pump and fan. As the water evaporates into the air, the air's temperature will lower. They are optimal when used in hot, dry climates used to filter ambient air while increasing the condensation and delivering cool airflow. Evaporative cooling fans do not use refrigerants to remove heat like an air conditioner, so they are less effective in high humidity areas.

Hessaire’s MC37M is the best and most effective cooling fan on the market for its size. It’s compact and yet packs a powerful blast of cooling with a patented winged prop design and three panels of high-density rigid media. Take it on the go easily with its four casters. It features oscillating louvers to cover a wide area quietly and efficiently. The manual controls make it easy for you to adjust between the four temperature settings to obtain optimal cooling anywhere you take the MC37M Evaporative Cooler.

Cooling the air is only a part of the process; propelling the chilled air into your space is what brings you needed relief. Specially engineered features from Hessaire allows this mobile evaporative cooler to provide an airflow of 3,100 CFM to your area. Proprietary fan propeller design with winglets throws the blast of cool air further and yet is very quiet. Additionally, the air swing delivery system moves cool air left to right across the room to ensure that air is evenly distributed.

Lifehack: it is the best humidifier
5 Stars
Lifehack: it is the best humidifier
We are in Arizona and we run it inside as a humidifier all winter long. During the heating season our indoor humidity was like 10-15%. This unit is running non-stop, consumes only about 200W and in Low fan speed evaporates 15-18 gallons of water every 24 hours. That is an insane amount - сompare this to your typical "ultrasonic humidifier" which will only do 0.5-1 gal! I drilled a hole in the top and dump a 5 gallon water bottle into it 3 times a day, or you can connect a refrigerator water line to it or a garden hose. Raises and maintains humidity around 80%. Feels like Florida when you come inside the house! No more dry hands and cracked finger tips!
