Are Small Dehumidifiers Worth It?

If you’re dealing with damp spots, condensation, or that musty smell in small spaces, a small dehumidifier is a fantastic solution. They’re perfect for bedrooms, bathrooms, wardrobes, and cupboards, keeping the air fresh and dry. If you live in a humid area or struggle with mould, a small unit can make a noticeable difference. Many models are compact, stylish, and easy to move around, so you can place them wherever they’re needed most.

How Much Do Small Dehumidifiers Cost to Run?

Good news—small dehumidifiers don’t use much electricity. Most run on 20 to 100 watts, which is way less than larger units. If you’re running a 50-watt dehumidifier for 12 hours a day, it could cost around 10-15p per day, depending on your electricity rate. Compared to the cost of dealing with damp damage or mould removal, it’s a small price to pay. Some models even have energy-saving features like auto-shutoff, so they’re not running when they don’t need to be.

Can I Leave a Small Dehumidifier on Overnight?

Yes, most small dehumidifiers are safe to leave on overnight, but it depends on the model. The key thing to check is whether it has an auto shut-off feature—this stops it from overflowing when the water tank fills up. A lot of people leave them on overnight in bedrooms, bathrooms, and even near laundry racks to speed up drying. Just make sure it’s placed on a flat surface with proper ventilation, and you’re good to go.
