Decoding the energy labels for ACs, Washing machines, and Dehumidifiers
Every appliance claim efficiency—but which performs best? Check the energy label to choose smarter air conditioners, washing machines, and dehumidifiers.
Air Conditioners
1. Choose Grade 1 air conditioners. Split-type air conditioners with a Grade 1 energy label can save up to approximately 50% in annual electricity costs compared to Grade 3 models. *# (Learn More)
2. Compare power consumption and estimate annual energy use.
3. Calculate efficiency (cooling capacity ÷ hourly power); a higher value means greater efficiency.
4. If your household has more members or you spend more time at home during summer, it’s recommended to choose a Grade 1 model with a higher energy efficiency ratio.
Washing Machines
1. Select Grade 1 washing machines. Washing machines with a Grade 1 energy label can save up to approximately 80% in annual electricity costs compared to Grade 3 models. *#(Learn More)
2. Compare the water consumption figures for each machine. The higher the number, the more water it consumes.
3. For larger households, avoid low-capacity machines and choose ones matching your laundry volume.
Dehumidifiers
1. Choose Grade 1 dehumidifiers. Dehumidifiers with a Grade 1 energy label can save up to approximately 50% in annual electricity costs compared to Grade 3 models. *# (Learn More).
2. Compare power use and estimate annual energy consumption.
3. Pick models with high dehumidifying capacity and efficiency—higher values mean faster, more effective moisture removal.
4. For homes near the sea or hills, opt for higher-capacity Grade 1 models to avoid overloading in spring and summer.
* Based on EMSD Mandatory Energy Efficiency Labelling Scheme website listed models (May 2025).
