At what cost

At around 60+ dollars, SPT SU-4010 is one of the cheapest models you can get your hand on a hybrid ultrasonic humidifier. It comes with all the ultrasonic goodness like a dual warm and cool mist controls, ION exchange filter, and even a cleaning brush. It is also a relatively cheap humidifier to maintain so it is basically a one-off fee. That said, if you are willing to top up around 20-30 dollars, that is a whole array of more powerful hybrid humidifiers to go for.
Where is the best place to purchase SPT SU-4010 Ultrasonic Dual-Mist Warm And Cool Humidifier? Amazon of course as both color options are available at a discounted price. You will also enjoy free shipping (subject to total order) and hassle-free shopping as everyone will have an Amazon account by now. SPT official website is also a good place to go as the pricing is competitive with the typical 30-days free shipping policy. Only applicable within the United States. You can also try searching it in your local retailers like Walmart, Home Depot but nothing beats the convenience of online shopping.

Other variants

Slightly more expensive and bulkier. You'll get a better moisture output, aroma tray, digital screen, and auto humidistats in return.

Same story with HuPro Premium Ultrasonic Cool & Warm Mist. A nicer case with higher moisture performance, full autonomous function, and remote control as standard.


  • Affordable and portable hybrid ultrasonic humidifier.
  • Compact humidifying performance that can cover a respectable 500 sq. ft. of room space.
  • Dual mist mode with warm mist at 400 ml and cool mist at 330 ml.
  • 360° adjustable bi-directional mist nozzle plus silent operation even at the highest mist speed.
  • Ion Exchange Filter helps prevent white dust particles from building up.


  • Top up around 20 dollars more for a full-size humidifier with digital display.
  • Small water tank that can only support up to 12 hours of humidification.
  • Lack of fan speed adjustment, timer, essential oil tray, and auto humidistat.
