For a water-saving washer, compare the model’s Integrated Water Factor (IWF): lower means less water consumed per cubic foot of capacity. Then weigh capacity, annual water and energy use, washer configuration, and whether the machine fits your laundry space. ENERGY STAR’s live product finder lists model-level figures; the examples below are starting points, not a definitive ranking.
How to compare water efficiency
Start with IWF
ENERGY STAR defines Integrated Water Factor as gallons of water consumed per cubic foot of washer capacity. A lower IWF indicates better water efficiency. It is a useful way to compare washers of different capacities, but it does not tell you the water used by every individual cycle or determine which washer is best for your household. See ENERGY STAR’s clothes washer guidance.
Consider capacity and annual use together
Compare capacity in cubic feet with the size of your usual laundry loads and the bulky items you wash. A larger washer may let you do fewer loads if you fill it appropriately; capacity alone does not guarantee lower water use. The product finder’s annual water and energy figures offer additional model-level comparisons, but annual water use is not a per-cycle figure.
Include energy efficiency
ENERGY STAR’s Integrated Modified Energy Factor (IMEF) indicates energy efficiency: a higher IMEF is more efficient. Check the washer’s EnergyGuide label as well for energy-use and estimated operating-cost comparisons. Your actual costs depend on local utility rates and use.
#1 Best Overall
- 〖Easy to Operate〗- On the control panel are there ten programs, 8 water level selections and LED display. All functions and operation including water level/spin, program/delay, time set and child lock are listed clearly. Detergent and procedure choice are also included to meet your various needs.
- 〖Compact Design & Large Load Capacity〗- Giantex washing machine is compact and lightweight for you to easily move it in your home. But the honeycomb shaped inner tub can load 12 lbs at a time and wash many clothes for you. In manual, we also listed weight of various clothes for your reference.
- 〖Time and Water Level Control〗- Under delay function, previous to washing, the digital timer shows your preset time but while it is washing, the digital timer shows the rest washing time. Pressing water level/spin button, you can select appropriate level. If you need to add water during washing, you can press water level/spin button and unlashing will stop adding.
- 〖Easy and Safe to Operate & Monitor〗- With detailed and specific manual, it is easy and convenient for you to operate it and inlet or drain water. Clear and transparent lid allows you to see and monitor the water and washing condition. Once child lock function is set, all buttons are locked and the machine stops running and error alarms if the top lid is opened.
- 〖Automatic Balance Adjustment〗- Automatic Imbalance Adjustment and Adjustable Foot. While spinning, if the laundries inside the tub are not put equally, it would cause violent vibration. At this time, our washing machine’s imbalance adjustment function will start automatically to adjust the imbalance situation if vibration is beyond certain level. Bottom feet can be adjusted to meet your needs.
Water-efficient washer examples
These models appeared in ENERGY STAR results sorted by IWF. Figures are live product-finder results accessed in 2026 for the first three models; results can change, so confirm certification and the complete model number, including its suffix, before buying. The LG SIGNATURE entry is from ENERGY STAR’s 2025 Most Efficient results and is identified as a 2025 recognition, not a 2026 award.
| Model | Configuration and capacity | IWF | Annual water use | Annual washer energy use | Source |
|---|---|---|---|---|---|
| Electrolux ELFW7738*** | Front-load, 4.5 cu. ft. | 2.6 | 3,452 gal/yr | 74 kWh/yr | ENERGY STAR product finder |
| LG WM5000H*A | Front-load, 4.5 cu. ft. | 2.8 | 3,676 gal/yr | 105 kWh/yr | ENERGY STAR product finder |
| LG WM4500H*A | Front-load, 5.0 cu. ft. | 2.9 | 4,278 gal/yr | 105 kWh/yr | ENERGY STAR product finder |
| LG SIGNATURE WM9901H*A | Front-load, 5.8 cu. ft. | 2.6 | 4,418 gal/yr | 108 kWh/yr | ENERGY STAR Most Efficient 2025 results |
The first three models are examples surfaced by the live product finder, not independently tested recommendations or a complete market ranking. A lower IWF does not settle the choice: capacity, the amount of laundry you actually wash, cycle selection, operating costs, fit, and price all matter. The table’s annual figures are model-level comparisons, not guarantees of a household’s actual use.

Choose a configuration that suits the laundry space
Front-load, top-load agitator, and top-load impeller machines differ in design and installation needs. ENERGY STAR’s buying guidance says certified front-load washers use about 50% less energy and water than top-load agitator washers, and about 25% less than top-load impeller washers. These are broad design comparisons, not promises for every model or cycle. The same guidance gives a general comparison of 14 gallons per load for a full-sized ENERGY STAR certified washer versus 20 gallons for a standard washer; it is not a measurement for every machine or selected cycle. Read the ENERGY STAR guidance for the qualifications.
If your space is constrained, compare the washer’s configuration—such as compact, stackable, laundry center, or all-in-one—with your installation requirements. The model examples above are front-load machines; the cited listings do not establish their exact dimensions, door clearance, hookup needs, or service availability.
