Find the right device for a perfect indoor climate in just a few steps
Measure the humidity level
Place Selina little in a sun light protected, slightly elevated place and observe the humidity for 24 hours. If it is permanently below 40% relative humidity, you will need a humidifier. If the air humidity is permanently above 60%, a dehumidifier can contribute to a better room climate.
Measure water hardness
Determine the water hardness with the enclosed test strip.
- Hold the test strip under the water to be tested for 1 second.
- Let the test strip dry for a minute. Make sure that the indicator fields are not touched.
- Read off the hardness of the water. With 4 green fields the water is soft, with 4 red fields the water is very hard.
IMPORTANT: With hard water from 14 ° dH we recommend not to use ultrasonic humidifiers or evaporators.
Determine the size of the room
The larger the room, the more powerful the humidifier / dehumidifier needs to be. We recommend a more powerful humidifier for minergie houses (low energy or passive houses) or apartments for which calculations should be based on twice the room size.
Here is the formula for calculating the room size in m2.
Length (m) x With (m) = Room size in m2
