It's important to remember when evaluating a list like this that none of the models available are going to do the kind of job that a full-sized humidifier can do. That's one of the reasons it's so hard to find models in the sector by recognizable companies like Vicks or Honeywell. What you do often find are jacked up aromatherapy diffusers that put out more mist than others on the market — just enough to offer some moisture to a driver or an individual in bed.
Capacity is one of the driving indicators of quality in these devices, as most users would want to find something that can run all night without drying up or shutting off. The FunnySeed Cool Mist is so highly regarded for that very reason, as both its water tank and battery are built to last the whole night through. And if you want to wake up and stay in bed without suffering dry air, it allows you to refill it without getting up to take anything apart and access its tank, which is a huge plus.
Consumers will have to ask themselves whether they want something that's compatible with essential oils, as some models seem designed specifically for that kind of use, while others prohibit it for the life of the device itself. In cases where aromatherapy is touted, you can safely assume that you're going to get slightly less humidification, and possibly a small water tank, to boot.
