Preparing the Humidifier:

Filling the Water Tank:

  1. Remove the water tank from the humidifier base.
  2. Open the tank's lid or top cover.
  3. Fill the water tank with clean, cool, and preferably distilled water. Avoid using hot or boiling water.
  4. Be mindful not to overfill; there is often a maximum fill line indicated on the tank.

Optional Aromatherapy:

Add a few drops of your preferred essential oil to the tray. Do not directly add the oil to the water tank.

Assembling the Humidifier:

Place the filled water tank back onto the humidifier base, ensuring it is securely seated.

Powering On the Humidifier:

  1. Turn the dial to "on" to power up.
  2. You can adjust the flow level depending on the room size.

Powering Off and Refilling:

When the water level in the tank is low, the humidifier may automatically shut off, or you can turn it off manually.

To refill the tank, power off the humidifier, unplug it, and follow steps 2-4 again.

FAQs

Why isn’t the humidifier blowing out much vapor?

Enjoy a steady stream of soothing vapor by checking the variable control knob is on the correct setting, and ensuring the oscillator is cleaned as well as the water tank is filled with fresh water.

The humidifier is leaking?

Avoid leaks by ensuring the filter cap is tight and the water tank is inserted correctly. If you are still experiencing leaks, please scan the QR code on the back of the box to watch our instructional video on how to set up your humidifier.

Why is the humidifier leaving lots of water around it or on my walls?

Eliminate water damage by adjusting the air flow setting to the lowest setting for a standard room. If you have a larger space, you can adjust the setting higher.

How often should I replace the water filter?

Keep your humidifier running smoothly and efficiently by replacing the water filter every 500 hours (every 3 months of 8 hours daily use). You can purchased one here.

Why does my humidifier have an odd smell?

Enjoy a fresh and clean scent in your home by using distilled water in your humidifier. Tap water can sometimes contain minerals that can cause a bad reaction with the humidifier, resulting in an odd smell.

Where do I pour the essential oils?

Add a touch of aromatherapy to your home by using the MEDESCAN special blend oil directly in the water tank. If you are using any other essential oil, please ensure you are using the tray located at the base of the Rainbow Mist.

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.

My Rainbow Mist looks like it is melting on the inside?

This is not because of heat, but actually if you have used essential oils that are not suited for this humidifier in the water instead of the tray in the back. If this has happened please contact customer support for replacing the bowl.

MedeScan Ultrsonic Cool Mist Humidifier

Works a treat. Mrs recovering from RSV with a lot of gunk on her chest. Running this during the night is helping her get it back up. Lasts a good 12 hours or more if your not running it flat out. Cool, quiet, great for the bedroom.

Does the job

I really like it as I no longer have such a dry mouth in the mornings. On the downside I only use it on the lowest setting and that only gives me about 13 hours over 2 nights.

Rainbow mist humidifier

I have bought this before and loved it, so I bought it again. This humidifier helps with my dry mouth at night, helping me sleep better. It also has a large water tank which I love, as I don't have to get up during the night to refill it!

Great Product

Purchased to help my asthma and blocked sinuses, works really well and helps me sleep at night, highly recommend this humidifier. I use it just with water, no oils. The cool mist has a really strong flow and whisper quiet, makes no noise at all.

powerful and effective

This has made such a huge difference when my heater is on in the winter. The air is perfectly humidified and I've stopped getting sore eyes and dry nose. Love that it also has a diffuser aspect where you can choose to use essential oils. The LED light is great as a night light and sometimes I just turn it on as I go to sleep without the humidifier running because of its lovely colours. Would recommend to everyone.

Functional, aesthetically pleasing

The humidifier is quiet and does a good job of providing enough humidity for a 300 sq ft bedroom. My dad has COPD and raising the humidity of the room helps his breathing. He’s started to sleep well at night. The colors serve as a convenient night light.
My 10 year old niece absolutely loves the changing colors and wants one for her room.

Medescan Rainbow Humidifier

Perfect, no need to use the oil pad though - that gives off no smell and just absorbs the oil. Use without the pads and it is perfect.

Great product

Works great. Great price. Fortunately the colours can be steady or off. I wish I could turn it a little lower but it is variable and can be nice and strong. The output is mist as described.

My daughter loves her night light and it also helps with her breathing during flu seasons

Had a replacement for the filter, i threw away the important part of the filter the screw in cap. I rang to see if i could order a new one, friendly staff was very helpful once again. To my amazement i was offered a new part free of charge. Thnx Medescan. One happy customer

I really like this Vaporiser

I loved this so much I bought two for each of my boys. This is the product we use when the kids are sick. It pumps out mist, which can be adjusted using the dial. My favourite feature is the top nozzle so I can change the direction of the mist. My kids favourite feature is the Rainbow light setting.

This Vaporiser lasts all night, is quite and easy to clean. Can take abit to dry out before storing away. Oils can be added in the back, though I don't think the scent lasts long.

Superb Product and Superb Customer Service

I own Medescan for 3-4 years and am extremely happy with it.
I LOVE IT. It is of excellent quality and design. I use it in the drier winter months. The rainbow lights are just so pretty to watch in the evening. Giving it a tranquil atmosphere. You can adjust the flow of the mist using the dial. The water tank lasts quite a while and is easy to refill. Honestly if you need a humidifier this is the one to buy. Also very grateful for the Superb and Friendly Customer Service of Team Medescan who were quick to respond to my enquiry and very helpful.
I highly recommend Medescan Rainbow Mist. :)
