What these numbers mean in practice

Capacity

4.5 cu ft is a mid-size drum for a front load machine. As a rule of thumb, one cubic foot holds roughly 3–4 kg of dry laundry, so this drum handles about 16 kg per load — enough for a queen-size bedding set.

Running cost

At 139 kWh per year, five years of use is about 695 kWh. Water use of 4,267 gallons a year works out to roughly 21,335 gallons over five years — the number that matters if you are on a metered water supply.

IMEF and IWF

IMEF is the integrated modified energy factor: higher is better, and it is the number behind the kWh figure. IWF is the integrated water factor: lower is better, and it is the number behind the gallons figure. Both are certified values, not marketing claims.
