QuietCool Stealth Pro 1.5: Whisper-Quiet Cooling for Small Spaces
Not every home needs a big fan. The Stealth line is QuietCool’s quietest, designed to run at night without disturbing sleep. The 1.5 moves about 1,480 CFM, enough for a small home, an ADU, or one zone of a larger house such as an upstairs bedroom wing that stays hot long after sunset.
