Dampness and mould aren't just annoyances - they’re warnings. Left alone, they bring health risks, bad smells, and damage that cuts deeper than you'd expect. The good news? A dehumidifier can be your best ally in keeping your space dry and healthy.
Link to Dampness and Mould in Your HomeDampness and Mould in Your Home
The first step in dealing with dampness and mould is understanding why they exist. High indoor humidity can come from everyday activities: cooking, drying clothes indoors, hot showers, even just the weather outside. When sufficient moisture is available, hundreds of species of bacteria and fungi - particularly mould - pollute indoor air (World Health Organization, 2009). Without a way to manage this moisture, condensation forms on cold surfaces, and mould finds the perfect home.
Mould is a serious health hazard. According to the World Health Organization, people living in damp or mouldy buildings are at an increased risk of respiratory infections, asthma attacks, and allergies (World Health Organization, 2009). Mould releases spores into the air that, when inhaled, can trigger these health issues, particularly for people who already have a respiratory condition or weakened immune system. And mould isn't just terrible for your health - it can also destroy your walls, ceilings, carpets, and furniture.

| Benefit | Description |
|---|---|
| Prevents Mould and Mildew | Mould spores struggle to survive when you maintain humidity levels between 40-60%. The World Health Organization emphasizes that keeping relative humidity within this range is one of the most effective measures to control mould growth and improve health outcomes (World Health Organization, 2009). |
| Improves Air Quality | Lower humidity levels reduce the number of airborne irritants, including mould spores, dust mites, and volatile organic compounds (VOCs). High humidity also fosters the growth of bacteria that can emit unpleasant odours and volatile organic compounds, both of which degrade indoor air quality (Wolkoff, 2018). Maintaining proper humidity with a dehumidifier helps in keeping these pollutants in check, resulting in cleaner air. |
| Protects Your Property | Excess moisture weakens the structure of your home—damaging wood, plaster, and even causing rust on metal surfaces. Controlling indoor moisture is essential to prevent these damages. The prevention or minimization of persistent dampness and microbial growth on interior surfaces is critical for avoiding structural damage (World Health Organization, 2009). |
| Enhances Comfort | High humidity feels stifling in the summer and adds to the chill in winter by making the air feel colder. Reducing humidity makes your living space more comfortable year-round. Research has shown that maintaining indoor relative humidity between 30-60% not only improves comfort but also reduces stress, sleep disturbances, and physical discomfort (Razjouyan et al., 2019). |

No magic bullet here. Dehumidifiers are fantastic at reducing indoor humidity, but they're only a part of the solution. To really solve moisture problems, you need to address the root causes too - like leaks and poor ventilation. For example, inadequate ventilation in a building allows moisture to accumulate, which contributes to mould growth and other health risks (World Health Organization, 2009). A dehumidifier can help manage symptoms of high humidity, but without eliminating the sources, such as poor insulation, a leaking roof or inadequate drainage, the issue will persist.

When it comes to picking the right dehumidifier, think about these factors:
-
Room Size: The capacity of the dehumidifier should match the room size. Larger rooms need higher capacity units to effectively control humidity. In poorly insulated spaces or colder areas, a desiccant dehumidifier is often more effective, as it maintains performance at low temperatures better than refrigerant models.
-
Energy Efficiency: Running a dehumidifier can be costly, especially if it's used frequently. Look for models that prioritise high extraction with low energy consumption. According to WHO guidelines, energy efficiency also plays a role in preventing building-related health issues since poorly controlled humidity can lead to increased energy usage for heating or cooling (World Health Organization, 2009).
-
Noise Level: If the dehumidifier is for a bedroom or living space, a quieter model is ideal. Units like the De'Longhi Tasciugo Ariadry are designed specifically for noise-sensitive areas.
-
Special Features: Features like laundry mode, child lock, and continuous drainage can make the use of a dehumidifier much more convenient. Consider these features when choosing a model that suits your specific needs.
Link to Additional Tips for Managing HumidityAdditional Tips for Managing Humidity
A dehumidifier works best when combined with a few smart practices:
-
Ventilation: Keep those windows open when possible. Proper ventilation is crucial in maintaining healthy humidity levels. Well-functioning ventilation systems can significantly lower the concentration of harmful airborne particles and prevent moisture build-up on surfaces (World Health Organization, 2009).
-
Use Extractor Fans: Extractor fans in kitchens and bathrooms help remove moisture generated during cooking or showering. According to Wolkoff (2018), the perception of poor air quality is closely linked with inadequate ventilation and high humidity, which fans can mitigate.
-
Fix Leaks: Leaks create the perfect environment for dampness and mould. Fix any leaking pipes or roofs immediately—a dehumidifier can’t keep up with ongoing leaks.
-
Avoid Drying Clothes Indoors: If you already have an existing mould problem in your home, drying clothes indoors can make the problem worse by raising indoor humidity levels. Using a dehumidifier with a laundry mode setting can mitigate the this. Other options are to use an outdoor clothesline or a tumble dryer vented to the outside.
Link to Common Questions About DehumidifiersCommon Questions About Dehumidifiers
-
Will a Dehumidifier Remove Existing Mould? No, dehumidifiers won’t get rid of existing mould. They prevent new mould from growing by controlling humidity, but existing mould must be removed through cleaning or professional remediation (World Health Organization, 2009).
-
How Much Does It Cost to Run a Dehumidifier? Costs vary based on wattage, usage, and local electricity rates. Most home models use between 200-300 watts, costing around £5-£10 per month.
-
Where Should I Place My Dehumidifier? Place your dehumidifier where the humidity is highest - typically bathrooms, basements, or laundry rooms. Ensure that it is centrally placed with good air circulation for maximum efficiency.
Link to ConclusionConclusion
Dehumidifiers are powerful tools for managing humidity and stopping mould in its tracks. But true success in eradicating mould permanently means going further - repairing leaks, improving ventilation, and solving the underlying issues that bring moisture into your home. Moisture control measures, such as ensuring proper building envelope insulation and addressing temperature differences that could lead to condensation, are just as important as using a dehumidifier (World Health Organization, 2009).
Pair dehumidifier use with smart practices, and you can keep your home comfortable, healthy, and mould-free.
