10 Best Mini Dehumidifiers

The EasyAcc 1200ml mini dehumidifier is a solid choice for small spaces like closets, bathrooms, or RVs, covering areas up to about 220 square feet. Its water removal capacity is about 400ml (14 oz) per day, which suits humid corners but may be slow for larger or very damp rooms. It operates quietly at under 35 dB, so it won’t disturb you during sleep or work, and uses low energy (only 0.79 kWh daily), making it cost-effective to run all day. The tank holds up to 1.2 liters of water, which is relatively large for a mini unit, reducing how often you need to empty it. An auto shut-off feature stops the device when the tank is full, preventing spills and adding safety.

The compact size with a handle makes it easy to move around, and seven LED color options provide gentle lighting during night use. It also includes a washable filter to keep maintenance simple. On the downside, the dehumidifying capacity is on the lower side compared to bigger units, so it’s best for small dampness problems rather than heavy moisture removal. The plastic build is lightweight but may not feel very rugged.

If you want a quiet, portable mini-dehumidifier that handles small spaces efficiently with convenient features like auto shut-off and night lights, this model fits well. However, it won’t replace larger, more powerful dehumidifiers for bigger or very damp areas.

The MeacoDry Arete® Two is a compact dehumidifier designed to remove up to 10 litres of moisture per day, suitable for spaces like flats, two-bedroom homes, or garages covering up to 42 square metres. It also doubles as an air purifier with a HEPA H13 filter, which helps clean the air from dust and allergens — a nice bonus if you’re sensitive to indoor air quality. It’s energy efficient, costing just a few pence per hour to run, which makes it practical for everyday use without worrying about high electricity bills. Noise is kept to a minimum at 35 decibels, quieter than many similar devices, and there’s a Night Mode that dims the display and reduces sound for undisturbed sleep.

The 10-litre tank means it can hold a good amount of water before needing emptying, and it will automatically shut off when full, so you don’t have to keep an eye on it constantly. A smart feature lets you control humidity levels via an app or voice commands, which is handy but might be more useful for those comfortable with smart devices. There’s also a Laundry Mode that helps dry washing indoors efficiently, saving energy compared to a tumble dryer. Weighing about 10.7 kg, it’s not the lightest option but still manageable to move around.

This model covers moderate spaces well and combines air purification with quiet operation. The price and smart features might be more than needed if you just want a simple dehumidifier, but for anyone looking to tackle dampness, improve air quality, and keep noise low in a home or flat, it offers a thoughtful mix of performance and convenience.

The ANSIO Dehumidifier 500ml is a compact, portable moisture absorber ideal for small spaces like wardrobes, bathrooms, kitchens, and caravans. It uses special crystals to draw in dampness and can absorb up to three times its own weight in water, helping reduce mould, mildew, and unpleasant odours. The tub has a 500ml capacity, which suits limited coverage areas rather than larger rooms. It doesn’t require electricity, so it’s energy-efficient and completely silent—great if noise is a concern.

Because it’s a disposable unit without an auto shut-off feature, you need to monitor it to avoid spills and replace it once full. The product is easy to use by simply peeling back the foil and placing it where needed, but it’s not designed for heavy-duty or whole-room dehumidification. It works well for tackling localized damp problems or supplementing an electric dehumidifier, especially in smaller or hard-to-reach spots.
