How to choose
Stainless steel tanks and cleaning
All three picks use stainless steel tanks. The Livatro tank is non-porous and resists residue and odors. The Livatro tank and the Jack & Rose removable parts go in the dishwasher, so check the parts list before you buy. The Techoney tank is easy to clean by hand, and it comes with a replacement misting plate and filter for longer use.
Tank size and runtime
Tank size sets how long a fill lasts, but the mist setting matters too. The Livatro holds 10 liters and runs up to 50 hours on low, and the Jack & Rose holds 3.5 liters and runs 20 hours. The Techoney holds 650 mL for personal use at a desk or bedside. Compare the tank size with the runtime figure, since a bigger tank does not always mean a longer run on every setting.
Controls and placement
The Livatro fills from the top, so you pour water in without carrying the tank, and it has a 0-12 hour timer and a control lock. Put the unit where the mist can spread and where you can reach it for refills and cleaning.
