Dreo Evaporative Air Cooler

4.2

3 sourcesall derived$172.98as of Aug 1

The Dreo Evaporative Air Cooler is the tower-style pick for anyone short on floor space. Reviewers highlighted its slim design, remote control functionality, and quiet operation, which suit a bedroom or office. Oscillation spreads air evenly, though some reviewers noted the tank needs frequent refills. At 13 pounds it moves between rooms easily, and it works best in small to medium-sized spaces rather than large areas.

Strengths

— Slim, compact shape that won't take up much floor space
— Remote control allows selection of three modes and four fan speeds from comfort of seat
— Quiet operation, especially in quiet mode

Watch-outs

— Frequent tank refills required
— Not suitable for large spaces

Ranked #4 in Best Evaporative Coolers

HESSAIRE MC37M

4.0

1 sourceall derived$395as of Aug 1

The MC37M is a portable evaporative cooler rated at 3,100 CFM with three fan speeds, a 10.3-gallon tank and a hookup for continuous water. It is built for garages, shop floors and open outdoor spaces rather than living rooms: no thermostat, no app, and a fan that is loud on high. Evaporative cooling also loses most of its effect once humidity climbs above 60 percent.

Strengths

— 3,100 CFM cooling capacity for effective room cooling
— 3-speed control for adjustable airflow
— Portable design with caster wheels for easy mobility

Watch-outs

— Loses most of its cooling effect once humidity climbs above 60 percent
— Adds moisture to the air, so it needs an open door or window to work
— Loud on the top fan speed, with no thermostat, scheduling or app control

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

Dreo Evaporative Air Cooler

While it lacks the powerful airflow of the MC37M or MC61M, its remote control and oscillation features make it better for personal comfort zones.

HESSAIRE MC37M

More airflow than the smaller Hessaire MC18M and easier to move than the MC61M, which holds more water and pushes more air. Against a window air conditioner it wins on portability and draws a fraction of the power, but it cannot cool a humid room at all.
