Hong Kong Dehumidifier Capacity & Running Cost Planner

Compare a portable dehumidifier with the published room-and-moisture capacity band, Hong Kong energy-label test conditions and editable HKD running-cost scenarios.

What dehumidifier capacity should I compare for a Hong Kong room?

Use room area and the moisture condition before dehumidification to find the published ENERGY STAR capacity band, then compare the Hong Kong label capacity in litres per day. Running cost still depends on the unit's watts, cycling and your tariff.

Method

The planner does not interpolate a proprietary model score. It keeps the published pints/day band intact, converts it to L/day, and separately calculates user-entered watts × hours × HKD/kWh.

Important limitation

This is not a mould, health or whole-home HVAC diagnosis. Capacity tests use specified laboratory conditions; actual extraction changes with temperature, humidity, airflow, doors, laundry and water ingress.

How to use the result safely

Treat the report as a measurement and comparison ledger. Recheck any margin near zero, compare the exact label or manual, and stop before purchase or drilling if a first-party requirement is missing.
