General questions about Dry

Ozoneair Dry is a flexible dehumidifier for warmer spaces such as laundry rooms, garages, and living rooms. It also purifies the air and has wheels, allowing you to easily move it where needed.

Ozoneair Guard is a desiccant dehumidifier designed for cold and exposed environments such as crawl spaces, unheated basements, and attics. It is permanently installed and works effectively even at low temperatures.

Ozoneair Dry is suitable for most indoor environments where you want to lower humidity – such as basements, laundry rooms, bathrooms, garages, storage rooms, and holiday homes. It operates in temperatures between 5–35°C and can be easily moved between different rooms thanks to its wheels. Perfect for everything from mold prevention to faster clothes drying.


Ozoneair Dry is designed to provide maximum effect in spaces of 10–120 m³, which corresponds to anything from smaller laundry rooms and bathrooms to larger garages, basements, or holiday homes. This makes it one of the most flexible choices on the market – perfect whether you want to prevent mold, lower humidity in your home, or dry clothes more energy-efficiently.

Ozoneair Dry delivers impressive performance:

  • 25 litres per day at 20°C and 70% RH
  • 50 litres per day at 30°C and 80% RH

This means the machine can effectively handle both daily humidity issues and more demanding environments – and you'll often notice a difference within the first 24 hours.

With a noise level of only 47–50 dB(A), Ozoneair Dry is a quiet choice in its performance class. This means it can be placed in household areas without disturbance, even during continuous operation.

Yes – the warm air is a sign that the machine is working correctly. The dry, slightly heated air also helps to speed up the drying of textiles and prevent condensation on cold surfaces.

By lowering the humidity, Dry counteracts mould, musty odours, moisture damage, rust and condensation. The filters also remove spores and particles.

Yes. Thanks to the built-in humidity sensor, it automatically adjusts to maintain optimal levels with minimal energy consumption.

The Technology

Ozoneair Dry uses advanced compressor technology where the air is cooled below its dew point. This efficiently condenses the moisture, which is then collected in a tank or drained away via a hose.

The technology is:

  • energy-efficient
  • very effective at normal room temperature
  • reliable with high water volumes even in humid environments

It has never been easier to create a comfortable and healthy indoor environment.

The machine uses R290 (propane) – a modern, environmentally friendly, and highly energy-efficient refrigerant used in premium products worldwide. Thanks to a closed system and comprehensive safety features, its use in a home environment is completely safe.

At temperatures below 5°C, the air's ability to carry moisture decreases, which is a physical phenomenon independent of the dehumidifier model. Therefore, the machine should be used within its optimal range of 5–35°C for maximum efficiency.

Usage and Maintenance

Ozoneair Dry has three smart user modes:

Manual

Perfect for those who want to control everything themselves – choose fan speed and target humidity between 30–95%.

Laundry

The most powerful mode. The machine runs at maximum capacity and dries laundry up to three times faster than air drying, saving both time and energy.

Auto

Convenient and fully automatic. The dehumidifier adjusts its capacity according to the air's humidity levels. You get a stable and healthy indoor environment without having to worry about settings.

For optimal effect, we recommend:

  • At least 45 cm of free space around the machine
  • A stable and level floor surface
  • Doors and windows closed
  • Do not tilt the machine more than 15° when moving it

This ensures optimal airflow – and you get the fastest possible dehumidification.

Absolutely! The Ozoneair Dry comes with a hose that easily connects to the outlet on the back. Perfect for basements, laundry rooms, or long-term operation without having to manually empty the tank.

Make sure the hose is sloped downwards all the way to avoid blockages.

Timer (1–24 hours): Perfect for night operation, electricity price optimization, or clothes drying.

Child lock: Activated by holding down the arrows for 3 seconds – ideal if the dehumidifier is placed in family areas.

The pre-filter captures larger particles and should be cleaned regularly – the dehumidifier will let you know when it's time.

The particle filter should be replaced every 6 months for best performance and clean air. A clean filter increases both dehumidification capacity and lifespan.

When the tank fills up, the machine will display E1, beep, and shut down automatically. This prevents spills and damage.

Empty the tank and put it back – the unit will then start in the same mode as before.

  • Clean the exterior with a soft cloth
  • Never block air inlets or outlets
  • Check the filters regularly
  • Do not use chemicals for cleaning

With proper care, your dehumidifier will maintain optimal performance for many years.

Absolutely. The cellar is one of the most common places where a dehumidifier makes a big difference. Ozoneair Dry is also adapted for Nordic climates and works down to 5 °C – perfect for cold and damp cellars.

Troubleshooting guide

Solution

  • Check that the dehumidifier is properly plugged into an electrical outlet and that the fuse is working.
  • Check if the water tank is emptied and correctly installed.
  • In Manual mode, check the humidity level the dehumidifier is operating against.
  • Try a different program.

Solution

  • Check if the set humidity level is higher than the ambient humidity.
  • Make sure that air can flow freely through the dehumidifier. Check that the pre-filter and particle filter are clean.
  • Check that no thick layer of ice has formed on the cooling elements, see the section on automatic defrosting.
  • Close any open windows and doors.

Solution

  • Ensure the dehumidifier is placed at least 45 cm from surrounding walls.
  • Ensure the dehumidifier is standing firmly on a flat surface.

Solution

  • Normal heat exchange.

Solution

  • The sound is caused by the flowing refrigerant, which is normal.

Solution

  • Place the machine on a stable surface.

E1
Water tank full/water tank not properly seated.

  • Empty the water tank/ensure the water tank is properly seated.

P8

High ambient temperature.

  • The dehumidifier will switch off automatically and restart when the ambient temperature drops below 35 °C.

HP

Outgoing air temperature is too high.

  • Switch off the dehumidifier and allow it to cool for at least 30 minutes.

E4

Fault in the outgoing air temperature sensor.

  • Unplug the power cord and contact your dealer or Ozoneair.

E5

Fault in the cooling unit's temperature sensor.

  • Unplug the power cord and contact your dealer or Ozoneair.

E6

Fault in the ambient temperature sensor.

  • Unplug the power cord and contact your dealer or Ozoneair.

Eb

Fault on the circuit board.

  • Unplug the power cord and contact your dealer or Ozoneair.
