I'm a big sock fan (like a hug for your feet). So when I say this humidifier blows my socks off,  you know there's something extra special about it (hint: Rainbow Mode!!!)...


The H2O UP Smart Humidifier


H2O cordless humidifiers come in 5 sizes. This is the H2O UP with the 2nd largest capacity at 1 litre and dual mist output... and oh my goodness, those lights. 

H2O UP comes in Snow Rainbow and Blush Rainbow colourways. This is the Snow, combining a crisp, sleek white, minimalist design with subtle silver chrome detailing. But wait. Switch on Rainbow Mode and prepare to be obsessed. This is the only H2O with Rainbow Mode.


Do your plants need a humidifier?

Humidity is about more than just spoiling your plants. Many of our favourite indoor houseplants come from naturally tropical habitats with high humidity all year round. Our heated and air conditioned homes cause them to suffer, even more so in homes with a fireplace, DVS or HRV which take excess moisture from the air.

Calathea, Stromanthe, Philodendron, String of Turtles, Orchids, Ferns... the list goes on and on of high humidity lovers. Signs to watch out for that your plants are asking you to raise their humidity include leaves with brown edges and tips and curling or wilting leaves even when you're meeting their soil watering needs. For flowering plants, also look for buds that fail to develop, or drop before they open, and flowers that shrivel soon after opening. Winter can be so much worse for our tropics loving plants too.


Up to 6 hrs run-time. 

Provide 3 to 6 hrs precious humidity for your plant's happiness depending on the mist mode. Plug in and run corded for continuous use using the included USB cord - which plugs directly in to a standard USB power board, a laptop or computer, or simply use your phone charger or cordless speaker brick, and plug in to the wall. 

Or go cordless and locate your plants in the best position for their needs, and your humidifier can go to them. No more restrictions to be near a power outlet. No more messy cords to wrangle.

For longer cordless run-times, check out the H2O 1.1 litre model or 750ml instead (their round designs give them more room for bigger batteries compared to this super slim design, so you get much longer run-times with the round models).

The H2O UP - is the only one with the blow-your-socks-off Rainbow Mode.

2 mist modes + auto shut-off.

Intermittent Mode 
cycles between 3 seconds on one mist outlet, then 3 seconds on the other, with one mist outlet going at a time. Halving the output and doubling the run-time when cordless. Continuous Mode provides a full, constant, higher output mist, from both outlets at once, for maximum humidity heaven.

One 1 litre fill lasts up to 6 hrs Intermittent Mode, or up to 3 hrs Continuous Mode. Plus your H2O UP is smart so will switch itself off automatically when the water level gets too low.

Super easy to refill. Just pull the top up, off the base, revealing the large 1 litre capacity water reservoir inside.


Don't do what I did, and lift it up by the top when you want to move the whole unit. Because doh! The top comes off the base, right? That's how you refill it. So guess what happens? Yep, tipsville. Small tsunami. Water everywhere. Argh. If you already own the other H2O humidifiers, you'll be used to lifting it any which way you please because they're round and the top screws on to the base. This model is not like that, so never lift only from the top (unless you feel like an impromptu shower). Not awesome. I made that mistake once. Don't be like me. 

Always pick it up from the base, so you lift the base and top at the same time.

4 LED light modes.

Prepare to be obsessed with these colour modes. 

1. Rainbow Mode

The first long press of the button puts you in Rainbow Mode. You have to see it in real life to truly appreciate it. A glorious rainbow of colours cycle around in the mist. And yes, you can run colour modes independent to mist modes if you just want to embrace those disco vibes. Video of Rainbow Mode here on Facebook for a sneak peek.

2. Ambient Mode

Second long press puts you in Ambient Mode. Each individual colour gently blends in to the next. Here are a few favourites...

3. Custom Colour Selector (or 4. Colour Off)

See a colour you love? Third long press selects that one colour to stay on. The last, long press turns colour off, so you can run mist only.


Super slim.

Tall, slim design. 17cms tall x 6cms wide x 15cm long. Simply slide it in amongst your plants. 

What's in the box?

Comes with the top, base, USB charging cord, 2 cotton filter wicks and built-in low water sensor with auto shut-off. Filter wicks last on average 3 months with daily use, so well worth getting a few extra when you buy your H2O. This model fits the Standard Wick size available here
