Who is it ideal for?

Bridging sentence: any home where relative humidity drops below 40 % in winter or when the air conditioning is running in summer.

• Families with young children who suffer from dry night-time coughs or frequent colds.

• Allergy and asthma sufferers who need to stabilise humidity to reduce attacks.
• Offices and home-working areas where dry air causes eye strain and headaches.

What humidity is best at home

The recommended indoor relative humidity is between 40 % and 60 %. Below 30 %, mucous membranes dry out, dry coughs get worse and respiratory viruses survive longer in the air. The HU 2031 keeps humidity stable during the cold months, when heating dries out the air.

Frequently asked questions

What room size is it suitable for?

It effectively covers rooms of up to 30 m². In standard 12-15 m² bedrooms it copes with ease; in large living rooms it is best placed near the seating area.

Is it noisy at night?

Ultrasonic operation is very quiet, suitable for leaving on all night in a bedroom. It has no internal fan, unlike warm mist humidifiers.

Can I use it in a baby's room?

Yes. As it produces cool mist, there is no risk of burns. Keep the appliance 1-2 metres from the cot and clean the tank every 2-3 days to prevent mineral build-up.

Can I use tap water?

It works with tap water, but if the water in your area is very hard, a fine white limescale dust will appear on nearby furniture. In that case, please use filtered or demineralised water and descale the tank once a month.

How do I clean it?

Empty the tank daily and rinse it with water. Once a week, fill it with a mixture of water and white vinegar (3:1), leave it for 30 minutes and rinse. This prevents biofilm and odours.

How much does it use per month?

At 25 W running 8 hours/night for 30 days, it uses approximately 6 kWh, which equates to around 1,2-1,8 € per month depending on your electricity tariff.

Can essential oils be used?

It is not recommended to add them directly to the tank of an ultrasonic water humidifier — the oils can damage the piezoelectric membranes. For aromatherapy, please use a separate diffuser.
