Smart Humidifier HM735S 11L

The 2.9-gallon tank is a game-changer—I only fill it once a week. The mist shoots up high enough to reach the far corners of my bedroom, and I haven't seen a speck of white dust anywhere.

I've got this in my open-plan living room and it actually keeps up without refilling every day, which was my main worry with a 2.9-gallon tank. The mist is genuinely ultrafine too — no white dust settling on my dark furniture like my old one left.

Filled this on a Sunday and didn't touch it again until Thursday, which says everything about that 11L tank. The ultrafine mist really doesn't leave any white dust on my furniture, and I can actually feel the difference in my bedroom within about twenty minutes of turning it on.
