The SereneLife 10000 BTU is a freestanding portable air conditioner with a rotary compressor, a dehumidifier mode and a washable filter. It is rated 10,000 BTU but its DOE cooling capacity is 6,000 Btu/h, so treat it as a room unit rather than a whole-floor cooler. It runs on standard 115V power at about 890W and is Energy Star certified with a 14.1 CEER. The best new price is $229.90 at Best Buy as of November 8, 2026, with 8 stores listing it new.
