I'm working in a small office in my apartment that's about 8 square meters. During the summer, the humidity levels are around 50-55%, which is perfect. However, in winter, it plummets to about 30-35%, leading to dry eyes, a scratchy throat, and frequent electrostatic discharges (ESDs). Last winter, one of those discharges even fried my keyboard and the USB controller on my PC, forcing me to replace the motherboard!
I want to keep the humidity above 45% this year but the ceramic humidifier I've tried isn't effective, only raising humidity from 35% to 37%. Plus, my office is filled with sensitive electronics—my PC, monitors, laptops, a printer, and a 3D printer with filaments—that are all near the limited power outlets. I'm concerned about using an electric humidifier that evaporates water because of the risk to my equipment.
What do you suggest? Am I being overly cautious about the ultrasonic humidifiers? Should I invest in a more expensive humidifier with smart features, or look for a cheaper option? Any advice is appreciated!

Using a humidifier shouldn't be an issue unless it's creating condensation on your devices. If you're using hard water, though, switch to distilled to avoid hard water stains.
I have a humidifier in my office too; it's been great! I fried a USB device last year, which was a wake-up call. I got one from Amazon that lets me set my desired humidity, so I avoid over-humidifying the area.
Do you have the evaporative type or the ultrasonic one? The ultrasonic is the one that throws up the mist.
I wouldn't want an ultrasonic humidifier too close to any fan intakes, but if it's across the room, it's generally fine. The mist tends to evaporate quickly when humidity's low. Watch out though, hard water can leave white dust around because it releases dissolved salts into the air! Just means you'll need to clean the humidifier less often, though. There are trade-offs with each type, too—check out some comparison videos to get a better idea.

I've seen those things use up to 4 liters a day... that can get pricey pretty quick!
