NEXT SHIPMENT ON THE WAY

It's not often a product that looks this good, performs just as good as it looks. 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).

Cordless. 2 mist functions. 4 light settings (I adore the glorious Rainbow Mode)... there's a LOT to love. Except watch out for the sneaky 'you'll-only-do-this-wrong-once' silly mistake (more coming up about that). Honestly, you really will make this mistake only once (then either crack up at yourself, or if you're as lucky as me, your partner will remind you endlessly of their amusement while you feel foolish)...

The H2O UP Smart Humidifier

H2O are a family of portable, wireless humidifiers in 4 sizes and 5 colours across the range. This is the H2O UP model, which has the 2nd to largest capacity, a higher dual mist output... and those lights (oh my goodness, those lights).

The 4 sizes are 200ml Mini, 750ml, 1.1 litre, and this is the newest model in the family, the H2O UP with a 1 litre capacity.

H2O UP only comes in the Snow Rainbow colourway. The other models come in Snow, Sage, Powder, Blush and Mint. Snow Rainbow combines a crisp, sleek white, minimalist design, with subtle chrome detailing. But just you wait. Switch those lights to Rainbow Mode and prepare to be obsessed.

This is the only humidifier in the H2O range 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 system, designed to take excess moisture from the air.

Calathea Orbifolia, Stromanthe Triostar, Philodendron Pink Princess, 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.

Long run-time.

The larger 1 litre capacity combined with 2000 milliamp hours battery, provides 3 to 6 hours of precious humidity for your plant's happiness, with 2 humidity modes, continuous (high) or intermittent (low).

Either 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 speaker brick and plug in to the wall.

Or (my favourite mode), run it cordless and locate your H2O UP anywhere you like. Completely portable and wireless. Now you can 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 ugly, messy cords to wrangle with.

For an even longer cordless run-time, you're better to go for 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. The 1.1 litre has double the battery rating (4,000 instead of 2,000 mAh) for longer cordless run-times, however note this model - the H2O UP - is the only one with the blow-your-socks-off Rainbow Mode.

2 mist modes + low-water 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 hours in Intermittent Mode, or up to 3 hours in Continuous Mode. Plus you can relax knowing your H2O Smart Humidifier will switch itself off automatically when the water level gets too low.

Super easy to refill and keep clean too. Just pull the top up, off the base, revealing the large 1 litre capacity water reservoir inside, with smooth sides for an easy, quick wipe clean when needed.

Here's where that WARNING comes in!

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 unless the base is full and heavy (so it stays behind and the top neatly lifts off), guess what happens? Yep, tipsville. Small tsunami. Water everywhere. Argh. If you already own any of the other H2O humidifiers, you'll be used to lifting it any which way you please because they're round, so the top screws securely on to the base. This model is not like that.

Always pick it up from the base, so you lift the base and top at the same time. Never lift only from the top (unless you feel like an impromptu shower). Not awesome. I was already in a grump the first (and only), time I made that mistake, so didn't share my partner's hilarity at the state of the floor and my jeans. Don't be like me.

4 LED light modes (including Rainbow Mode)

Yes, I know this feature is 100% for the people, not our precious plants, but if you're anything like me, prepare to be obsessed with these colour modes.

At first all I could do is be mesmerised by Rainbow Mode. Then I graduated to the calm, chill Ambient Mode, and now I've advanced to the single Colour Selector mode (this gorgeous peachy pink is my current favourite to pick, but scroll through the photos to see more). I do keep changing my favourite and selecting new colours.

1. Rainbow Mode

The first long press of the settings button puts you in Rainbow Mode. You have to see it in real life to truly appreciate this mode. It's hard to capture on video. A glorious rainbow of colours cycle around in the mist. And yes, you can run the colour modes independent of the mist modes if you just want to embrace those disco vibes with the mist off (I shared a video of Rainbow Mode here on Facebook if you want a sneak peek).

2. Ambient Mode

The second long press of the settings button puts you in Ambient Mode. Each individual colour gently blends in to the next. Not sure I could accurately count the number of colours, but here are a few favourites...

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

See a colour you love? The third long press of the settings button, selects that one colour to stay on. Then the last, long press turns colour off altogether, so you can run mist only, no colour.

Compact, slim design for plant shelves

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

What's in the box?

Your new H2O UP Smart Humidifier comes with the top, base, USB charging cord, 2 cotton filter wicks and built-in low water sensor with auto shut-off.

Those filter wicks last on average 3 to 6 months with daily use, so it's worth grabbing a couple replacement filter wicks when you buy your H2O UP. They fit the Standard Wick size. You can change them separately, one at a time (they need 2), but it's worth changing both for new each time, so best to grab an even number.
