Frequently Asked Questions (FAQ) - Airfresh Hygro 500

The humidifier and the air washer are equipped with an integrated air humidity sensor. The actual humidity of 20% RH to 95% RH is shown on the Display.

The white and/or yellow deposits are calcium carbonate particles that have developed from the minerals in water. Calcium carbonate on the filter impairs the proper function of the humidifier. Therefore, you must clean the humidifier filter every two weeks. Use a solution made from water and vinegar, at a ratio of 1:1, or vinegar essence at a ratio of 3:1. Place the filter in the vinegar–water solution for one hour. Then rinse subsequently with clean water before putting the filter back into the Airfresh Hygro 500. Note: Should any dark patches appear on the filter, or if there is an unpleasant smell, the filter must be replaced.

In automatic mode, the air humidity is monitored continually by the digital sensors. This then leads to the humidifier being switched on and off as needed, to ensure the humidity in the room is always kept at the correct level. Humidity levels are normally considered to be comfortable at between 40%–60%. The standard humidity in automatic mode is 50%, but this can be adjusted as required.

Fill the tank with clean water daily. Clean the bottom compartment with warm water and a soft cloth every 10–14 days. Never leave water in the bottom compartment for extended periods. Water left in the Airfresh Hygro 500 can lead to mineral deposits and can create conditions that are conducive to the growth of unwanted micro-organisms. In addition, the filter must be changed if it starts to show dark patches.

Evaporation Technology utilises the principle of cold evaporation. It offers cold humidification that is up to 99% free from bacteria, in comparison to other humidification methods.

If the water level gets too low, the red symbol on the display will light up. This shows that the water needs to be refilled. If you do not refill the water, the Airfresh Hygro 500 will continue to run for as long as it takes for the existing water in the tank to be used up and for the filter to be completely dry.

1.)    The replaceable, absorbent filter collects large articles such as hair and dust as it sucks in the dry air
2.)    The hygienic and efficient evaporation technology ensures that bacteria is not able to settle in the water or during the humidification process
3.)    The Airfresh Hygro 500 blows the clean air out evenly, providing comfortable and natural air purification for your home
