Does anyone have a single room humidifier they can recommend that is super quiet? I bought one at Costco yesterday for about $90 a preguardian 120 hour one and it ran quietly but then about every 20 mins it made this "glugging noise" when it sucked water from the tank that woke me up (I'm a really light sleeper.) It sounded like the cat was barfing, no joke So if anyone has one they like I'd love to know!
