Overview
A 5,000 BTU window-mounted air conditioner rated for rooms up to 150 sq ft, running on standard 115V household power at 450W. It includes two fan speeds, a washable filter and auto restart.
At 5,000 BTU this sits at the small end of window units, sized for a single small bedroom or office rather than an open living space. Auto restart returns the unit to its last settings after a power outage, a detail that matters more than it sounds in areas with unstable power.
- 5,000 BTU, cools up to 150 sq ft
- 115V / 450W standard outlet
- Auto restart after power loss
- Washable filter, extra-long power cord
Who it's for
Fits a small bedroom, nursery or home office up to about 150 sq ft where quiet operation matters more than raw cooling power. Not sized for larger rooms or open-plan spaces.
Pros and cons
- Rated for rooms up to 150 sq ft
- Quiet rated operation at 52 dBA
- Auto restart resumes prior settings after a power cut
- Washable filter, no replacements to buy
- Only 2 fan speeds, no smart or app control
- Small BTU rating limits it to one small room
Performance notes
Effortless Temperature Control holds the unit at a preset temperature rather than just cycling on a timer, and two fan speeds offer a basic choice between airflow and quiet. Frigidaire rates the unit at 52 dBA, and the filter is washable rather than a replaceable cartridge.
