The Frigidaire portable 3-in-1 AC unit with 12,000 BTU (ASHRAE) typically offers cooling, dehumidifying, and fan functions. It often features Wi-Fi connectivity for app control, a programmable 24-hour on/off timer, a remote control, and a sleep mode. Many models include a clean air ionizer, auto-swing louvers for better air circulation, and an easy-to-clean washable dust filter. Users generally find it effective for cooling medium-sized rooms and appreciate its smart features, though some note it can be noisy and the single exhaust hose may heat up.
