Just like the best units for your home, the best office humidifiers will put moisture back into the air to help ease irritated sinuses and dry skin. They’ll also be the right size and capacity for your intended space — but when humidifying an office in particular, you’ll also want to make sure that the one you choose is quiet and compact, so it won’t distract you or your coworkers. (For that reason, there’s often a lot of overlap between the best humidifiers for the bedroom and those for the office.)
First, figure out how large of a space you’re looking to humidify. If you’d like a little more moisture around your desk or cubicle, a personal USB unit should do the trick. However, for full-room or whole-office humidifying, you should calculate the square footage of your workspace before you start shopping. Some of these larger units have the necessary mist output to tackle spaces of up to 2,700 square feet — and their large water tank capacities mean less frequent refills. Auto-shutoff can be a nice perk for offices as well, and all the picks below have it. Finally, consider if you want a filter or filterless design. Filterless models are easy and cheaper to maintain in the long run, but filtered models can reduce minerals going into the air (minerals that might otherwise leave a white dusting on your desk).
