The useful answer
The 25L is the highest-extraction Arete Two on paper. Meaco publishes 10.85 L/day at 20°C / 60% RH and 3.55 L/day at 10°C / 60% RH. It shares the 20L's 4.8-litre tank, dimensions and 255 m³/h maximum airflow, so the decision is mainly about extraction headroom, input, weight and price—not physical capacity alone.

Transparent energy example
What does 250 W mean in pounds?
At an example electricity rate of 25p/kWh, the published input at 20°C / 60% RH equals about 6.25p per powered hour. Twenty powered hours would be about £1.25.
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.
Put the 25L beside the 20L before checkout. At the normal comparison condition, Meaco publishes 2.35 L/day more extraction for the 25L and 43 W more rated input. In the colder 10°C / 60% RH condition, the published extraction gap narrows to 0.20 L/day.
- Highest published extraction in the range at both 20°C / 60% RH and 10°C / 60% RH.
- Up to 255 m³/h airflow and a 4.8-litre tank.
- No larger external dimensions than the 20L according to the current specification.
- App control, voice control, louvre, laundry timer and continuous drainage.
- Published weight is 16.1 kg and the model is not wall mountable.
- Published input at 20°C / 60% RH is the range's highest at 250 W.
- The top noise setting is 50 dB(A), while the low setting is listed at 40 dB(A).
- In a regularly cold space, compare desiccant technology rather than relying on the largest compressor model number.

Exact-model questions
What buyers usually need clarified.
Does the Arete Two 25L collect 25 litres a day at home?
Not necessarily. Meaco publishes 10.85 L/day at 20°C / 60% RH, 3.55 L/day at 10°C / 60% RH and 25.25 L/day only at 30°C / 80% RH. Home collection depends strongly on actual conditions.
How much does the Arete Two 25L cost to run?
Its published input is 250 W at 20°C / 60% RH. At an example rate of 25p/kWh, that is about 6.25p per powered hour at rated input. Actual cost changes with tariff, mode, conditions and duty cycle.
Is the 25L physically bigger than the 20L?
Meaco currently publishes the same 618 × 366 × 272 mm dimensions, 4.8-litre tank and 255 m³/h maximum airflow for both. The 25L is listed 1 kg heavier and has higher extraction and rated input.
