After using the Tanness dehumidifier for a week, I’ve found it to be an efficient and practical addition to my home. It’s a 12-liter compressor-based model that performs well in managing humidity across my 140m² house. Positioned in the largest room at the farthest corner from where we sleep, it effectively regulates humidity throughout most of the home while remaining quiet enough not to disturb us at night. The sleep mode is particularly effective, reducing power consumption significantly while still maintaining adequate extraction, with over 2 liters of water collected daily even at a 50% humidity setting. For a compressor model, it’s as quiet as can be expected, with most of the noise coming from the compressor itself. The water tank on the Tanness is thoughtfully designed. It’s easy to remove, carry, and replace without any risk of leaks, though it does take a little getting used to. There’s also an option for continuous drainage, which I haven’t tried yet. While researching the model online, I discovered a nearly identical unit called the Wessex, which appears to be the same dehumidifier with minor cosmetic differences. The Wessex manual, which I found online, is identical to the printed one that came with my Tanness, reinforcing the impression that it’s a simple rebranding. In terms of performance, the Tanness compares similarly to premium models like Meaco. It’s rated as a 12-liter dehumidifier, which means it can theoretically collect up to 12 liters per day under ideal conditions, such as 30°C and 80% relative humidity. In real-world conditions, particularly during winter when colder air holds less moisture, it collects around 2–3 liters daily, which is entirely normal. Compared to my almost two-year-old 25-liter Electriq model, the Tanness is more efficient and seems to regulate humidity more effectively. The Electriq appears to be declining in performance after two hard years, possibly due to wear or an inaccurate hygrometer making it think it has frosted up or the compressor is losing gas. Screenshots I’ve taken demonstrate the Tanness’s ability to maintain consistent humidity levels and highlight its low power consumption. You can see toward the end of the humidity curve the humidity started to climb after the tank for full and the device shut down. The real world power was apps on average less than 120 watts making it cost effective to run. The Tanness fits seamlessly into my three-dehumidifier setup. Alongside it, I use a Meaco Junior desiccant dehumidifier and the older Electriq model. The Tanness handles most of the everyday workload, set to maintain 50% relative humidity, while the Meaco Junior, set to 60%, steps in for high-demand situations like cooking, or quickly drying laundry if set to a laundry mode. The Junior is incredibly effective but less energy-efficient, so I use it as a “peak shaving” device for these situations or when the temperatures drop below 15°C. For showers, I often rely on the Electriq in manual laundry mode while the others remain in auto mode. This setup ensures consistent humidity control while keeping energy use to a minimum. While I’m pleased with the Tanness so far, its durability remains to be seen. Premium brands like Meaco are known for their longevity, with many lasting over a decade, while my Electriq is already showing signs of decline before 2 years. I’m optimistic that the Tanness will hold up well, but only time will tell. The only areas for improvement I’ve noticed are the water tank size, which could be slightly larger, and the manual, which is somewhat vague. However, the unit is simple enough to operate with some trial and error, so these are minor issues. Overall, the Tanness is an excellent dehumidifier that strikes a good balance between noise, energy efficiency, and extraction rate. It’s already proving to be an essential part of my home setup, and I expect it to pay for itself in energy savings compared to relying on larger, less efficient units. If its long-term performance matches its initial efficiency, it will be a worthwhile investment.
