How to Get the Most Out of Your Dehumidifier
Managing indoor humidity effectively not only enhances your home’s comfort but also protects your health and property. In this guide, we’ll explore why dehumidifiers are so beneficial, the different types you might choose, the humidity sweet spot you should aim for, efficient use strategies, and how to choose the right Duux Bora model for your needs. Let’s dive in.

Reasons to Use a Dehumidifier
Excess Humidity
Moisture buildup in rooms often results in condensation appearing on windows, damp patches on walls, and that unmistakable musty smell. These are early signs that humidity levels are too high and that a dehumidifier can provide immediate relief. Excess humidity can also damage paint and wallpaper, and over time, even lead to structural issues.
Control Mould and Mildew
Humidity levels above 55–60% create the perfect environment for mould and mildew to flourish. Excess fungal growth in your home can lead to problems such as allergies, asthma and respiratory irritation, as well as damage to paint, wallpaper and soft furnishings.
Drying Clothes
Indoor drying, especially in colder or rainy seasons, can elevate humidity significantly. A dehumidifier helps extract this excess moisture, reducing drying time and preventing dampness. It can be far more energy-efficient and gentle on fabrics than a tumble dryer.
Types of Dehumidifiers
Desiccant Dehumidifiers
Desiccant dehumidifiers use moisture-absorbing materials, working well even at lower temperatures. Ideal for unheated spaces such as basements and garages, and can even work effectively below 12°C. They tend to run quieter but will use more energy when placed in warmer environments, such as heated rooms.
Refrigerant (Compressor) Dehumidifiers
Refrigerant Dehumidifiers work by cooling air to condense water vapour on cold coils, which is most effective in warmer environments (above 15 °C). Refrigerant dehumidifiers offer more consistent performance, higher efficiency and rapid humidity reduction. The Duux Bora models use compressor technology to dehumidify.

What Is the Ideal Humidity?
45–50% is the perfect range
While most professional bodies recommend an ideal indoor humidity of 40-60% relative humidity (RH), there are advantages to keeping a more refined relative humidity range of 45% and 50% for optimal health, comfort and home preservation.
Mould needs an RH of 55% or higher in order to grow, so a maximum RH below this can help to avoid issues caused by mould and fungus. The energy cost of dehumidification rises as the RH drops, and air that is too dry can also lead to issues such as dry eyes, skin and throat. Very low humidity can also affect your health, weakening your respiratory system’s defences and increasing susceptibility to airborne viruses.
Benefits of maintaining this range
Protect House and Belongings
Balanced humidity protects your home and belongings, too low can cause damage to wood furnishings and floors, as well as a build-up of static electricity. When humidity is too high can lead to peeling paint, and fabric from cracking, warping in wooden floors and furniture as well as potential condensation damage to electronics.
Prevents Mould and Mildew Spores from Growing
Keeping humidity under 55% limits spore germination and surface condensation, helping you avoid serious health and structural risks. Mould and mildew growth can also do damage to the home and furnishings, as well as causing an unpleasant musty smell.
Better Comfort and Health
Proper humidity reduces allergy risks, respiratory irritation, and static while supporting mucous membrane health—boosting sleep quality and general well-being.
Efficient Use
To maximise your dehumidifier’s effectiveness and energy efficiency:
Place away from walls and furniture: Leaving your dehumidifier in a central position in your room promotes optimal airflow and uniform dehumidification. If this is not possible due to space constraints, leave at least 20 cm clearance to the sides and 50 cm clearance above to promote optimal airflow and uniform dehumidification.
Clean the filter regularly: Some dehumidifiers have built-in filters, typically carbon or pre-filters to remove smoke, odours, and dust from the air. Cleaning or replacing the filters keeps the unit running efficiently and extends its lifespan.
Run recommended self-cleaning cycles: Some dehumidifiers also feature a self-cleaning cycle, which should be run at the recommended intervals.
Keep windows and doors closed: When dehumidifying a room, it is particularly important to prevent humid outdoor air from entering the room, as this increases the workload on your dehumidifier. Likewise, if it is too easy for air from other parts of the house to enter the room, this can also reduce the effectiveness of the dehumidifier.
Use continuous drainage where possible: Dehumidifiers will shut off when the tank is full; however, some come with a hose attachment option, which can be set up to drain the water into a sink or drain. When this option is available, it is a perfect way to avoid emptying the tank frequently, allowing for long, continuous operation. Both Duux Bora models support this.
Use Laundry-Drying Mode: Some dehumidifiers, such as the Duux Bora, include a dedicated laundry-drying mode. This mode runs for a set duration and is optimised for energy-efficient drying of clothes, using up to 50% less energy than traditional tumble dryers.

Which Should You Choose?
- Choose the 20 L model for standard rooms, bedrooms, kitchens, or damp spots in average-size homes.
- Go for the 30 L model if you’re dealing with larger spaces, cellars, laundry rooms, or persistent damp conditions and need to reduce the humidity faster.
Additional Useful Tips
- The Duux Bora features a built-in hygrometer for measuring the relative humidity in the room; however, this is a measure from a single location. When you have significant humidity issues, consider adding a separate hygrometer in different areas to verify and fine-tune humidity control.
- Many bathrooms and kitchens have extractor fans. These can be a good way of removing excess moisture in conjunction with a dehumidifier.
