Product information Eva little

Despite her delicate stature, Eva little is very powerful. With a footprint of just two bars of chocolate, the little one disperses 320 ml of moisture into the air. Eva little uses ultrasound technology to generate a visible mist that quickly increases the room's air humidity. Essential oils for aromatherapy can be used in the compartment designed specifically for this purpose.

Room size
For Minergie houses and flats (low-energy, energy-efficient or passive buildings) with controlled ventilation, the room size must always be doubled when selecting a humidifier. For example, if the room size is 25 m², a humidifier for Minergie buildings should be selected for rooms of at least 50 m². The reason for this is the continuous exchange of air: cold and dry outside air is warmed up and fed into the interior. The humidity in the interior is continuously transported to the outside. The result is extremely dry indoor air, especially in winter. Controlled ventilation systems act like windows that are always open, which is why the recommended room size for the humidifier should be twice as large as the room to be humidified.


Water quality
If your water at home is very hard (from 14 °dH) or you use a water softener, we advise you not to use an ultrasonic nebuliser. With an ultrasonic nebuliser, the limescale (or the salt from the water softener) in the water will also be turned into tiny particles which will then settle as a white deposit. If you have hard water, we recommend using an evaporator (e.g. Oskar). You can find out the hardness of your water using a test strip or even by contacting your local authority.

Please read through the operating instructions carefully before you use the appliance for the first time and keep them safely for later reference; if necessary pass them on to the next owner.

  • Do not run the power cord over sharp edges and make sure that it does not get trapped.
  • Do not pull the plug from the socket with wet hands or by holding on to the power cord.
  • Do not use the appliance in immediate vicinity of a bath tub, a shower or a swimming pool (observe a minimum distance of 3m). Place the appliance such that a person in the bath tub cannot touch the appliance.
  • Do not place the appliance near a heat source. Do not subject the power cord to direct heat (such as a heated hotplate, open flames, hot iron sole plates or heaters for example). Protect power cords from oil.
  • See to it that the appliance is properly positioned to ensure a high stability during its operation and make sure that no one can trip over the power cord.

Different measured values can occur with different placements, heights, air flows and temperatures. The appliance measures most accurately in the centre of the room with a free flow of air. If it is positioned against the wall, a distance of at least 30 cm should be maintained. Direct contact with furniture, heaters or the sun should be avoided as they can falsify the measurement and have a negative effect on humidification efficiency. In the case of ultrasonic nebulisers with a hygrostat, the mist emitted can influence the measurement of the humidity around the device – the value displayed therefore does not always correspond to the actual humidity in the room.

The intensity of the fragrance is influenced by various factors:

  • Type of fragrance (synthetic, natural, ingredients, etc.)
  • Room temperature and relative humidity (the more humid the air, the stronger the fragrance will be)
  • Room size (the smaller the room, the more intense the fragrance)

In principle, you can increase the intensity of a fragrance by adding a little more fragrance oil. The strength of a fragrance will depend on the fragrance itself. Natural fragrances are often more discreet than synthetic ones and certain ingredients are more dominant than others. It should also be remembered that first and foremost, the device is a humidifier. Its main focus is to provide humidity in the room and because of that, the intensity of its fragrance will never be as strong as the fragrance from an aroma diffuser.

For hygienic reasons and to ensure flawless operation, we recommend the following cleaning intervals. Caution: Never immerse the device in water (risk of short circuit).

Daily: Fill the water tank with fresh, cold tap water. If the device is not used for several days: empty the tank, clean it if necessary, and refill with fresh water before use.

Every 2 weeks: Remove all individual parts (e.g., water tank, mist chamber, Water Cube). Clean the water tank with a little dish soap, warm water, and a soft cloth, sponge, or brush. For lime scale deposits, use a descaling agent diluted with water (according to the manufacturer’s instructions) and rinse thoroughly with cold water. Reassemble all parts and insert the Water Cube afterward – alternatively, our hygiene tabs can be used.

At least once a month: Perform a complete cleaning and descaling according to the user manual.

Regularly, as needed: Wipe the exterior with a damp cloth and allow to dry thoroughly.

End of the season: Before storing the device at the end of the season, descale it, clean it thoroughly inside and out, and let it dry completely. Gather all accessories now so that your humidifier is ready for use at the start of the next season.

We are currently changing the accessories that come with our humidifiers. Previously, the Water Cube was included, but now Hygiene Tabs will be included in the scope of delivery. The change is being implemented on an ongoing basis and will be handled according to the first-in-first-out principle. Therefore, during the transition phase, we cannot guarantee in advance whether you will receive Hygiene Tabs or a Water Cube with your humidifier. However, both versions ensure water hygiene in your humidifier, are functionally equivalent and compatible with the device.

The ultrasonic technology turns the water into mist. In the process, the limescale in the water is converted into minute particles which are then deposited as a white film on furniture. That is why we recommend using an anticalc cartridge which will reduce the limescale content in the water. If the water is hard (14–21 °dH) or very hard (from 21 °dH), you will have to change the cartridge very frequently in order to prevent the occurrence of the white film. Eva little should not be operated using decalcified water from a water softener which is based on the principle of ion exchange (salt is added to the water) either. The salt contained in the water can also accumulate around the device in the form of white dust. For that reason, we recommend using an evaporator if you have extremely hard water or decalcified water.

Alternatively, distilled water can also be used. Video distilled water
If you notice droplets (or other signs of moisture) on or around the device, this is condensed water from the humidifier. This means that the air can no longer absorb the moisture from the humidifier. Please reduce the humidification output to such an extent that droplets are no longer visible.
All devices with a production date of May 2019 (SN number 1905 xxxxx, see the rating plate on the bottom of the device) or later are equipped with new technology and therefore have a float switch. Please start off by checking that the float switch (red arrow) can move up and down. It may be that it has become stuck due to excessive limescale/dirt. Descale the water tray regularly in order to ensure fault-free operation.

Please rinse out Eva little’s water tray thoroughly with warm water and make sure that the membranes are free from limescale. Descale the water tray, if necessary. Make sure that no water gets into the air opening in the water tray. Fill the water tank and start Eva little again. If the red LED still lights up, please remove the anticalc cartridge (located on the inside of the water tank, attached to the water tank cover) and leave Eva little running without the anticalc cartridge for 30 minutes. If Eva little still does not work properly after doing this, please contact the retailer from whom you purchased your Eva little so that you can have her repaired.
