Keeping the laundry room dry and well-ventilated is a challenge in many Swedish homes. Moisture from freshly washed clothes, combined with poor ventilation, can quickly create an unfavorable environment with a risk of mold, unpleasant odors, and unnecessarily long drying times. Dehumidifiers in the laundry room play a crucial role here. By installing an efficient dehumidifier, you can not only improve air quality but also lower energy consumption and get clothes to dry faster – often at a fraction of the energy a tumble dryer consumes.
Benefits of using a dehumidifier in the laundry room
A dehumidifier in the laundry room offers several practical and economic benefits, both short-term and long-term. Here are some of the most prominent:
Better indoor environment
- Reduces the risk of mold, bacteria, and unpleasant odors.
- Contributes to healthier air quality.
- Prevents moisture damage to walls, ceilings, and floors.
Shorter drying time for laundry
- Efficiently extracts moisture from clothes and the air in the room.
- Reduces the need to use a tumble dryer.
- Allows air drying even in smaller spaces.
Long-term energy savings
- A dehumidifier often uses only 1/3 of the electricity compared to a tumble dryer.
- Reduced use of tumble dryers leads to lower electricity costs.
- Energy-efficient solution for households with high laundry volumes.
Extends the lifespan of clothes
- Gentler than tumble dryers, which can wear out textiles.
- Preserves the garment's shape and color better over time.
How a dehumidifier affects drying time in the laundry room
Understanding the drying process in the laundry room is key to optimizing both energy consumption and time. When you hang freshly washed clothes in a closed or poorly ventilated space, drying can take several hours, sometimes even days. This is where a dehumidifier in the laundry room makes a big difference – it changes the entire dynamic by actively extracting moisture from the air, creating a drier microclimate that significantly accelerates the drying process.
What happens when you dry without a dehumidifier?
- The air quickly becomes saturated with moisture.
- Water in the clothes evaporates slower.
- Laundry feels damp and clammy long after you've hung it up.
- In the worst case, condensation forms on walls and windows, which can lead to mold.
With a dehumidifier in the laundry room:
- The relative humidity is quickly lowered.
- Moisture evaporates more easily from textiles.
- Drying time is often reduced by 30–70% compared to natural air drying.
- Air circulation is improved, contributing to even drying.
Example: Drying time in practice
| Drying Method | Average Drying Time (jeans, towels) | Energy Consumption (per wash) |
|---|---|---|
| Air drying without assistance | 8–16 hours | 0 kWh |
| Tumble dryer | 1–1.5 hours | 1.5–3 kWh |
| Dehumidifier + air drying | 3–6 hours | 0.3–0.8 kWh |
As you can see in the table above, a dehumidifier for the laundry room offers an optimal balance between speed and energy consumption. Drying time is often halved compared to traditional air drying, while electricity consumption is much lower than when using a tumble dryer.
Ideal use: Dehumidifier + drying rack
For best effect, you should combine the dehumidifier with a wall-mounted or floor-standing drying rack. Place the dehumidifier on the floor with free access to the air around the laundry. Most modern models have:
- Hygrostat (measures humidity)
- Timer or continuous mode
- Auto shut-off when correct humidity is reached
- Low noise level, often below 40 dB
By using these functions, you can let the dehumidifier in the laundry room work when needed, without wasting energy unnecessarily.
Environmental impact and sustainability
Switching to a dehumidifier instead of a tumble dryer also has environmental benefits:
- Lower CO₂ emissions due to less energy consumption.
- Longer lifespan of clothes reduces the need for new consumption.
- Better indoor climate contributes to a reduced need for air conditioning.
Dehumidifier vs. tumble dryer – which is the smartest choice for the laundry room?
When faced with the choice of investing in a dehumidifier for the laundry room or a classic tumble dryer, there are many factors to consider. Both solutions have their advantages and disadvantages, but as energy prices rise and sustainability becomes increasingly important, dehumidifiers have become a more attractive option for many households.
1. Function and use
Tumble dryer:
- Works by rotating clothes in a drum while hot air is blown through the fabric.
- Often requires exhaust air or condensation management.
- Fast drying – often done in 1–2 hours.
Dehumidifier:
- Removes moisture from the air, allowing clothes to dry naturally faster.
- Requires you to hang up the laundry, preferably in a smaller room.
- No direct heating – dries by creating a drier climate.
2. Energy consumption and cost per use
One of the biggest differences between dehumidifiers and tumble dryers is how much energy they consume. Here is a general comparison:
| Unit | Energy Consumption per Use | Cost per Use (approx. 2 SEK/kWh) |
|---|---|---|
| Tumble dryer | 1.5 – 3.0 kWh | 3 – 6 SEK |
| Dehumidifier (3–6 h operation) | 0.3 – 0.8 kWh | 0.60 – 1.60 SEK |
Conclusion: The dehumidifier is on average up to 5 times cheaper to operate than a tumble dryer.
3. Environmental impact
- Tumble dryers consume a lot of energy, leading to higher greenhouse gas emissions, especially if electricity comes from fossil fuels.
- Dehumidifiers have significantly lower electricity consumption, and if combined with air drying (on a line or drying rack), the climate impact is minimal.
4. Impact on clothes
Tumble drying wears out clothes, as most people who have experienced shrunken sweaters or faded textiles can attest.
- Heat and friction in tumble dryers can:
- Shrink clothes
- Wear out fibers faster
- Reduce the lifespan of textiles
- Drying with a dehumidifier:
- Gentler on fabrics
- Preserves shape and color better
- No mechanical stress
5. Noise level and convenience
- Tumble dryers can be quite noisy (over 60 dB).
- Dehumidifiers often have lower noise levels (35–45 dB), especially if designed for indoor use.
However, a dehumidifier requires a bit more planning: you need to hang up the laundry and let it dry naturally, which can take a little more time and space – but with the right placement and ventilation, it works very smoothly.
6. Investment cost and lifespan
| Product | Purchase Price (approx.) | Lifespan | Maintenance Costs |
|---|---|---|---|
| Tumble dryer | 4,000 – 12,000 SEK | 7–10 years | Medium (filters, hoses) |
| Dehumidifier (high capacity) | 1,500 – 5,000 SEK | 10–15 years | Low (filter cleaning) |
A good dehumidifier for the laundry room is cheaper to buy, cheaper to run, and often lasts longer than a tumble dryer.
How to choose the right dehumidifier for the laundry room
Choosing the right dehumidifier in the laundry room is not just a matter of price. It's about matching the machine's capacity and features to the size of the laundry room, airflow, humidity level, and how often you do laundry. Here's everything you need to know to make an informed decision.
1. Capacity – how much moisture needs to be removed?
Dehumidifier capacity is often stated in liters per day (e.g., 10L, 20L, 30L), indicating how much water it can extract from the air within 24 hours.
Capacity guidelines:
- Up to 10 liters/day – Suitable for small laundry rooms or occasional use.
- 10–20 liters/day – Appropriate for medium-sized laundry rooms with regular washing.
- 20–30+ liters/day – For large households, heavy laundry loads, or basement apartments where moisture levels are high.
Tip: It's better to choose a slightly more powerful model than to overload an underpowered machine.
2. Hygrostat – automatic control
A built-in hygrostat is crucial in the laundry room. It measures humidity and automatically starts or stops the dehumidifier to maintain a constant level (usually between 45–60% RH).
Advantages:
- You don't have to manually turn the machine on and off.
- Saves energy.
- Increases the lifespan of the machine.
3. Air circulation and fan speed
The better the air circulation, the faster clothes dry. A good dehumidifier in the laundry room should have adjustable fan speeds.
- High fan speed: Better circulation and faster dehumidification.
- Low fan speed: Lower noise level, perfect for night operation.
4. Water drainage
There are three types of drainage:
- Manual drainage: The reservoir must be emptied by hand (suitable if you are home often).
- Automatic drainage via hose: Connect directly to a drain – perfect for laundry rooms.
- Pump function: For spaces where the drain is higher than the dehumidifier (e.g., basement).
5. Noise level – especially important in the home
If your laundry room is near bedrooms or living areas, the noise level is an important aspect. Many models range between 35–50 dB.
| Noise Level (dB) | Experience |
|---|---|
| 30–40 dB | Very quiet (like a refrigerator) |
| 40–50 dB | Equivalent to a quiet conversation |
| 50+ dB | Noticeably loud |
6. Energy efficiency and eco-labeling
Looking for an eco-friendly dehumidifier? Choose a model with:
- Energy rating A or better
- Environmentally labeled refrigerant (R290 or R134a)
- Eco mode or timer function
7. Extra features that can be useful:
- Drying mode / Laundry mode – Optimal for drying laundry.
- Display with real-time data – Shows current humidity.
- Child lock – Safety feature if the laundry room is accessible to children.
- Carbon filter – To neutralize odors from damp laundry.
How to optimize the use of a dehumidifier in the laundry room
Using a dehumidifier correctly in the laundry room is key to faster drying times, better indoor air, and lower energy consumption. Here are concrete tips to help you get the most out of your investment.
1. Correct placement is crucial
The placement of the dehumidifier greatly affects its efficiency. Generally, the following applies:
- Place it near the laundry – no more than 1–2 meters from where clothes are hanging.
- Free air circulation – avoid placing the machine too close to walls or in corners.
- On the floor – warm air rises, but humid air is heavier and collects near the floor.
- Away from water sources – keep a distance from the washing machine's spill zone.
Tip: Try placing the dehumidifier in the middle of the room with directed airflow towards the laundry.
2. Use the correct settings
Most dehumidifiers have different operating modes. In the laundry room, it's best to:
- Set the target humidity to 45–55% RH.
- Use "Laundry mode" or the highest fan speed for very damp laundry.
- Schedule with a timer function if you wash at the same times every day.
- Night mode if the machine runs in the evening – reduces noise level.
3. Combine with the right drying method
The dehumidifier works best in combination with drying racks or clotheslines. Here are some ways to further improve drying:
- Leave space between garments.
- Use a fan if possible for extra air circulation.
- Keep doors and windows closed – otherwise, the effect will be lost.
- Dry heavier garments separately – jeans, towels, etc., hold more moisture.
4. Maintenance for optimal effect
Just like other machines, a dehumidifier in the laundry room also needs regular maintenance to keep its performance at its peak.
Maintenance checklist:
- Empty the water reservoir (if a hose is not used) regularly.
- Clean the filter at least once a month.
- Wipe air intakes and outlets from dust and lint.
- Check hose connections and drainage system.
5. Common mistakes to avoid
Many users lose the benefits of a dehumidifier through small mistakes. Here are the most common:
- ❌ Placing the machine too far from the laundry.
- ❌ Opening windows/doors during operation.
- ❌ Setting too high target humidity (above 60% RH).
- ❌ Allowing the filter to become clogged – drastically reduces efficiency.
- ❌ Overloading the laundry room with too much wet laundry at once.
6. Smart scheduling and energy-saving tips
- Use electricity at night (cheaper electricity prices).
- Run the dehumidifier immediately after hanging up laundry – not hours later.
- Have a separate electricity meter connected if you want to monitor consumption accurately.
