Frequently asked questions about Eva little
With ultrasonic technology, the water is converted into mist. At the same time, limescale in water is converted into minute particles, which are deposited as a white film on furniture. This is why we use an anticalc cartridge in Eva little as it reduces the limescale content in the water. If the water is harder than 21 degree dH, this cartridge would have to be replaced very often, in order to prevent the white film. For this reason, we recommend using our evaporator or air cleaner (e.g. Oskar, Oskar big, or Robert) for very hard water.
Do not operate Eva little with decalcified water out of a decalcification system that uses the principle of an ion exchanger (salt is added to the water). The salt contained in the water may lead to white dust accumulation around the appliance. Therefore, please use distilled water or hyper-filtrated (reverse-osmosis) water for Eva and take out the anticalc cartridge. The mixing ratio should be 50:50.
To minimize the risk of white dust (see FAQ "Where does the white film come from?"), you can operate Eva little using a mix of distilled and tap water. The mixing ratio should be 50:50. Attention: Please do not operate the unit using pure distilled water as the water level indicator will not work correctly.
A flashing humidity value means that the desired humidity has been reached and the device has switched off automatically.
The desired humidity can be changed by pressing the “Hygrostat” button several times (35 – 75 % and continuous operation “CO”). The symbol on the display blinks during input. After a few seconds without input, the selected value is saved. The symbol changes to the current measured humidity.
If the anticalc cartridge is not replaced frequently enough, a white film of limescale is formed from the water. If you notice such a film, the cartridge needs to be replaced. A white film can also originate from water from decalcifying systems. In this case, however, it does not come from limescale but from the salt in the unit. Therefore, please use distilled water or hyper-filtrated (reverse-osmosis) water for Eva little. The mixing ratio should be 50:50. Attention: Please do not operate the unit using pure distilled water as the water level indicator will not work correctly.
Run the cleaning mode at least once per month. The appliance must be off for at least 15 minutes prior to internal cleaning! Then remove the water tank, the mist chamber, the silicone cover, the Water Cube and the fragrance container. Fill a cup with 200 ml of tap water mixed with descaling agent (mix according to the manufacturer’s instructions). Pour the liquid carefully into the water tray by holding the cup directly over the water tray. Do not pour the liquid into the water tray from high above the tray! Be sure that no liquid enters the air inlet opening. This will damage the appliance and will avoid any claim to the warranty. The following video shows the correct cleaning.
You can use any common household scents, fragrances, aroma oils or essential oils. We recommend using oils that are as natural as possible without alcohol e.g. pure essential oils from Stadler Form.
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 intensive 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.
Please rinse the water base of Eva little with warm water and make sure the ultrasonic membrane are free of any limescale residues. Descale the water base if necessary. Be careful not to spill any water into the air opening of the water base. Fill the water tank and start Eva little again. If she still displays the red light, please remove the anticalc cartridge (positioned on the inside of the water tank, attached to the water tank cap) and let Eva little run for 30 minutes without the cartridge. If Eva little still does not run properly, please get in touch with the retailer you purchased Eva little from to start the repair process.
Eva little operates based on the principle of ultrasonic nebulisation. With this process, a membrane turns the water into tiny droplets which are then blown into the room as mist by a fan before they evaporate. The following video explains how the various humidification systems work and why no mist is visible with evaporator humidifiers (such as e.g. Oskar).
