Portable Tanness 12L Dehumidifier Review 2025: Key Features & Performance Explained

If you’ve been thinking about adding a humidifier to your home or office to improve air quality or handle humidity levels, I recently tested the Tanness 12L Dehumidifier, and I’m here to share my personal experience to help you decide if it’s the right fit for you.

I’ve been using it for a while now, and it’s given me plenty of opportunities to test all of its functions.

In this Tanness 12L Dehumidifier review, I’ll cover everything you need to know—from the key features to its performance, including how easy it is to use and maintain.

Key Features & Specifications

Let’s start with what the Tanness 12L Dehumidifier brings to the table.

After using it, here are the features I found to be the most important and why they matter to you:

• 12 Litre Daily Capacity: This is a major selling point because it can extract up to 12 litres of water from the air per day. This is perfect for larger spaces or rooms with high humidity.
• Water Collection Tank: It has a 1.8-litre tank that collects the moisture it pulls from the air. If you’re using it in a smaller room, this may be enough for a while before needing to empty it.
• Continuous Drainage Mode: One of my favorite features is the option to connect a hose pipe to continuously drain the collected water. This is incredibly useful if you want it to run non-stop without worrying about emptying the tank.
• Humidity Control: You can easily set the desired humidity level anywhere from 30% to 80%. I found it to be very responsive, and once it reaches the set level, it automatically adjusts the operation to maintain it.
• Laundry Mode: This feature is a real highlight. When set to laundry mode, the humidifier runs continuously, helping to dry damp clothes or reduce humidity in a space. It works well if you live in a place where clothes dry slowly, especially during winter.
• Nighttime Mode: This is a thoughtful addition. It operates at a lower speed and quieter setting, which helps maintain a comfortable environment while you sleep. I found it ideal for those who are light sleepers.
• Timer Function: You can set it to run for intervals of 1 to 24 hours, giving you full control over how long you want the unit to run.
• Fan Speed: It has low and high fan speed settings, so you can adjust depending on how quickly you want it to work.
• Child Lock: The child lock feature is super convenient, especially if you have little ones around. Once your settings are adjusted, you can lock them in place to prevent anyone from accidentally changing them.
• Filter Maintenance: After about 600 hours of use, the filter requires cleaning to maintain optimal performance. It’s a bit of maintenance, but it ensures the humidifier keeps working effectively.

Design & Build Quality

When it comes to design, the Tanness 12L Dehumidifier is pretty straightforward and functional. It features a modern, clean design that fits easily into most home or office settings without standing out too much.

Here’s a closer look at what I think of the design and build:

• Portability: The humidifier has wheels and a handle for easy movement. Whether you want to move it from room to room or place it in a different corner, this feature makes it simple to adjust.
• Water Tank: The 1.8-litre water tank is located at the back and is easy to remove and refill. There’s a handy display to show how much water is left, so you can keep track of when it needs to be emptied.
• Hose Connection: For those who prefer to avoid emptying the tank, the included hose allows for continuous drainage. This is a big plus if you need the unit to run all day, such as in a laundry room or humid environment.
• Filter: The filter is located at the back and needs to be cleaned after about 600 hours of use. While this is standard maintenance for many humidifiers, it’s something to consider if you prefer a more low-maintenance device.
• Build Quality: Overall, the build quality feels durable, and it’s clear that the unit is designed for frequent use. The controls are intuitive and easy to operate, making it accessible for anyone, regardless of tech-savviness.

Performance & User Experience

Now, let’s dive into how the Tanness 12L Dehumidifier performs in real-world conditions.

Here’s how I found it to work day-to-day:

• Moisture Extraction: The humidifier does an excellent job of removing moisture from the air. I noticed a significant improvement in air quality after running it for a few hours, especially in rooms with high humidity levels. The 12-litre extraction per day is impressive, and it’s noticeable when you compare the humidity level before and after use.
• Laundry Mode: As someone who deals with damp clothes in the winter, laundry mode is a game-changer. It runs continuously and pulls moisture from the air, which helps clothes dry faster. I’ve used it multiple times to speed up the drying process, and it worked great.
• Nighttime Mode: This feature is particularly useful for sleep. The humidifier operates at a lower, quieter setting in nighttime mode, which I appreciate. It’s not completely silent, but it’s quieter than the regular settings and doesn’t disrupt sleep.
• Ease of Use: The controls are very user-friendly, and the display is easy to read. Setting the desired humidity level is simple, and it responds quickly to changes. I liked how you can switch between settings without hassle—whether you need to adjust the fan speed or set a timer, everything is right at your fingertips.

Pros & Cons

Like any product, the Tanness 12L Dehumidifier has its pros and cons. Here’s a summary of what I liked and didn’t like about it:

Pros:

• Efficient Moisture Extraction: 12 litres per day is a significant capacity, especially for large rooms or high-humidity areas.
• Laundry Mode: A fantastic feature for drying clothes or reducing dampness in a room.
• Nighttime Mode: Quiet operation at night ensures minimal disruption while you sleep.
• Portability: Wheels and a handle make it easy to move around.
• Customizable Settings: You can set the humidity to your exact preference, giving you full control over your environment.
• Child Lock: A useful safety feature, especially in households with young kids.
• Continuous Drainage: The hose connection is perfect for hassle-free operation.

Cons:

• Water Tank Size: While the tank holds 1.8 litres, you’ll need to empty it regularly unless you use the drainage hose.
• Noise on High Settings: When on the high fan speed, the noise level can be a bit much for some, though it’s not too loud overall.
• Filter Maintenance: After 600 hours, the filter requires cleaning, which is a bit of upkeep to consider.

Final Verdict & Recommendation

After using the Tanness 12L Dehumidifier for a while, I can confidently say that it’s a great investment for those looking to improve air quality, manage humidity, or dry clothes more efficiently.

Its laundry mode and nighttime mode really set it apart from other humidifiers I’ve tested, and the ease of use and portability are added bonuses.

If you’re okay with some minor maintenance (like cleaning the filter and emptying the tank), this unit offers a lot of value for the price.

✅ I highly recommend this humidifier if you’re looking for a reliable, efficient, and versatile option. It’s perfect for both residential and office use, and it makes managing your indoor environment much easier.
