How can I change the colour on my Rainbow Mist?

Enjoy a calming and relaxing atmosphere by changing the colour of your Rainbow Mist. Simply press the LED ON/OFF button to cycle through the 7 different colours, or hold the button down to select your favourite colour.

How do I clean my Rainbow Mist Top Fill Humidifier?

Keep your Rainbow Mist Top Fill Humidifier running smoothly and efficiently by cleaning it regularly. Simply use a soft damp cloth on the interior/exterior of the humidifier. Changing the water every 2-3 days will help to prevent the build-up of bacteria and minerals.

How long will the humidifier last once filled to max?

Enjoy a steady stream of soothing vapor for up to 20 hours when using the Rainbow Mist Top Fill Humidifier on the lowest setting. On the highest setting, you can expect up to 10 hours of use.

What setting should I use for the mist control?

The best setting for the mist control will depend on the size of the room you are humidifying. For a standard room, you should use the lowest setting for the mist. For larger spaces, you can use the medium or highest mist setting. Also, ensure the nozzle is facing an open space, otherwise this will cause the mist to leave drops on walls if not aimed correctly.

Why does my humidifier have an odd smell?

This can be caused because of the type of water you are using. Some tap water has minerals that can cause a bad reaction with the humidifier. The best solution is to clean out the humidifier with warm water and a damp cloth. Let it air dry and use distilled water.

Why does my humidifier have no mist coming out?

Please check that the middle section is properly inserted. If it is, then you may need to clean the humidifier. You can also try using distilled water instead of tap water.

Rachana (Perth, AU)
Easy to use

Does great job. Easy to use, refil and emptying is easy. Love the beautiful lights

Cliff (Perth, AU)

Have been using this roughly the past 2.5 months and so far its reliable and the mist generated is consistent. I like the colours of lighting options available, especially the light blue while the mist is running. It creates a pleasant vibe.

Cazabel (Glasgow, GB)
Nice light and strong

We have two of these now however this one is a bit funny as the light switch isn’t in line with the press button and so is sometimes hard to turn on and off. Other than that it’s great for sick kids which we have all the time. Strong flow and nice light. Is large but and have to still refill nightly or every 2nd night but easy top fill.


Great product

Rainbow Mist Top Fill Ultrasonic Cool Mist Humidifier

Kaye N. (Adelaide, AU)
Love it!!

Love this Ultrasonic Cool Vaporiser, I've had the worst chest infection for over 5 weeks. In the beginning it was a dry unrelenting choking cough!
My daughter lent me her to see if it helped, which it did. So I quickly purchased my own, I'm still using it every night. We are in winter and I have the A/C on all the time, which dries the air out! So I'm running it all night from my bedside table!
It's not an expensive outlay and is something every home should have.

Mr. s.m. (Melbourne, AU)
Good product

I m using medescan for long time..this is my second ..touch buttons need to improve the sensitivity.. timer good option but if it turns on every hour once more nicer..flow is too much even in minimum setting..old model u can vary the flow..
