Key buying factors
Match tank size to room square footage. Larger tanks (5-6L) run all night, while small 200ml units are for desks.
Ultrasonic models are quietest (under 30 dB). Fan-based units may be louder. Check decibel ratings for bedroom use.
Built-in humidistat lets you set target humidity. Digital controls and auto shut-off add convenience.
Filterless ultrasonic models need regular cleaning to avoid white dust. Evaporative models use wicks that need replacement.
Look for wide openings and dishwasher-safe parts. Hard-to-clean tanks breed bacteria.
Essential oil trays, night lights, remote control, or programmable timers can add value.
