  1. Check Before Buying Estimate a Heater's Monthly Electricity Use from Its Power ConsumptionConvert W to kW and multiply by hours of use to estimate a heater's electricity use. This separates an assumed calculation from actual use and from the electric bill.
  2. Check Before Buying Check What to Look For in a Dehumidifier's Efficiency GradeKeep a dehumidifier's efficiency in L/kWh separate from its dehumidifying capacity. Compare the power consumption, size, and agency-registered values of the LG 20L and 13L candidates together.
  3. Reading Efficiency Grades Read the Efficiency Grade and Rated Power Consumption of an Electric Rice CookerKeep a rice cooker's efficiency grade and rated W separate from the actual energy used for cooking and keeping warm. The official figures of two Cuckoo 6-cup models are compared in one table.
  4. Reading Efficiency Grades Read the Efficacy (lm/W) Rating on LED Lighting ProperlyLED lm/W is a figure for the amount of light per unit of power. Check the luminous flux, socket, and dimmability of two Philips 8W candidates at different color temperatures together.
  5. Check Before Buying Check Whether Air Purifiers Have an Efficiency Grade TooAir purifiers can be looked up by efficiency grade too. Separate coverage area, power consumption, and standby power, and see how the registered grades of two LG models differ.
  6. Check Before Buying Check the Efficiency Grade of a Clothes Dryer Before You BuyTell kg, per-cycle Wh, and efficiency grade apart on a clothes dryer. This also covers the official installation sizes of two LG models and the difference in their agency-registered grades.
  7. Check Before Buying Check the Efficiency Grade Label on a Washing Machine Before You BuySeparate standard top-loaders from front-loading drum machines and compare candidates of similar wash capacity. This looks at the grade, power consumption in W, and door-open space of two LG models together.
  8. Reading Efficiency Grades Check How an Electric Heater's Minimum Efficiency Mark Differs from the Regular GradesThe standard-met mark in the electric heater list is not a rank from grade 1 to 5. Read the agency's efficiency level separately from the official power consumption of two Shinil models.
  9. Check Before Buying Compare Kimchi Refrigerator Efficiency Grades by Capacity, Not Grade AloneChoosing a kimchi refrigerator by grade number alone misses differences in capacity. Compare the agency list's effective volume and monthly power consumption side by side with the official LG specs of three models.
  10. Reading Efficiency Grades Check the Standby Power Marks on Products Before You BuyStandby power is checked with the warning mark (mandatory for products that miss the standard) and the Energy Saving Mark (voluntary for those that meet it). Here is how the two differ and how to search.
