The useful answer
The 12L is the strongest compact-chassis proposition on paper: Meaco publishes the same 136 W input as the 10L at 20°C / 60% RH but 5.40 L/day rather than 4.19 L/day. That makes it the logical first comparison for regular laundry or a broader small-home job, provided a compressor model suits the temperature.

Transparent energy example
What does 136 W mean in pounds?
At an example electricity rate of 25p/kWh, the published input at 20°C / 60% RH equals about 3.4p per powered hour. Twenty powered hours would be about £0.68.
This is an input calculation, not a bill prediction. A dehumidifier can cycle after reaching its target, and temperature, humidity, fan mode and the moisture source alter runtime. A larger model can also finish a demanding task sooner.

Where this model makes sense—and where to pause.
Choose between the 10L and 12L on job intensity, purchase price and availability—not on published normal-condition wattage, which is currently identical. Move to the 20L comparison when the managed area, recovery time or moisture load justifies its larger chassis, tank and airflow.
- Published 5.40 L/day extraction at 20°C / 60% RH from a 136 W rated input.
- Same compact dimensions, fan settings and 2.5-litre tank format as the 10L.
- Wall-mount compatible with a separately purchased bracket.
- App control, voice control, louvre, laundry timer and continuous drainage.
- The published weight is 10.9 kg, slightly above the 10L's 10.7 kg.
- Published extraction at 10°C / 60% RH is 1.97 L/day, so assess cold spaces separately.
- The 2.5-litre tank may require more frequent emptying under a sustained moisture load.
- A larger model may finish an intensive job sooner even though its rated input is higher.

Exact-model questions
What buyers usually need clarified.
Is the Arete Two 12L more expensive to run than the 10L?
Meaco currently publishes 136 W for both at 20°C / 60% RH. At an example 25p/kWh, that is about 3.4p per powered hour at rated input for either model. Actual runtime and duty cycle can differ.
What is the real extraction rate of the Arete Two 12L?
Meaco publishes 5.40 L/day at 20°C / 60% RH and 1.97 L/day at 10°C / 60% RH. Those condition-specific figures are more useful than reading the 12L model number as an everyday promise.
Is the Arete Two 12L suitable for drying laundry?
It has a dedicated laundry mode, directional louvre, timer and up to 140 m³/h airflow. Drying time still depends on load size, spacing, room temperature, ventilation and the starting moisture content.
