These appear quite powerful for their small size, they shoot out a visibly large amount of steam. But, don’t let the amount of steam coming out fool you, it is super dispersed, even if you hold your hand right above the steam, it will never condense on your hand. Compared to a real humidifier, if you place your hand above the steam, your hand will get wet, meaning it’s actually putting out much more water than these things. You’d probably have to have these running for a few hours to elevate humidity compared to a good humidifier running for 30 minutes. For a diffuser they’re perfect, as a humidifier a solid NEGATIVE! I have an electronic RH (relative humidity) meter, and these barely raised the RH by less than 5%. I only bought these to help my tropical plants in summer, and even then, humidity never went past 45%. But since I live in the California desert, I will take any humidity increase I can. The lights are also pretty cool, with a large variety to choose from. The wood design is a little on the cheap looking side though, but for the price I’d say it’s worth it.
NOT a humidifier
