How this humidifier scores for different use cases
At only 10.5 ounces and 7 inches tall with USB power, this is built for travel. The 3.5-hour battery runtime and compact size make it easy to pack and use in hotel rooms or cars.
The compact 2.51" x 2.51" footprint and USB power make this ideal for a desktop. Quiet operation and 10-hour runtime cover a full workday when plugged in.
The 8.5 oz tank only lasts up to 10 hours plugged in, which barely covers a full night. Quiet operation and color-changing night light help, but the tiny tank capacity limits bedroom reliability.
Cool mist and auto shut-off are good safety features, but no BPA-free certification is listed and the very small tank requires frequent refills. No humidistat means you cannot monitor room humidity levels.
This is a personal portable humidifier with an 8.5 oz tank. It has zero capability to humidify a large room or whole home.
No WiFi control, no app control, no voice assistant integration, and no remote control. This product has zero smart home capabilities.
Our Verdict
The HoMedics Portable Humidifier is a travel-first device. It fits in your bag at 10.5 ounces and runs on USB or battery power.
You get up to 10 hours of mist when plugged in. On battery alone, expect about 3.5 hours. That covers a short flight or car ride.
The 8.5-oz tank is tiny. You will refill it often if you use it at home. This is not a bedroom humidifier for all-night coverage.
Two mist settings and a built-in timer give you basic control. The color-changing light adds a nice touch in hotel rooms.
Top-fill design and easy-clean features keep daily use simple. Three included wicks save you from buying replacements right away.
This humidifier has no smart features at all. No app, no WiFi, no voice control. Keep that in mind if you want automation.
At $24.99, you pay for portability and convenience. You do not pay for power or coverage. The value is fair for what it does.
Buy this if you travel often and want personal mist nearby. Skip it if you need to humidify a bedroom or any room larger than your desk.
