LG, EdgeStar and Haier are among the suppliers of compact washer and dryer combination units. These appliances are similar in their physical outer dimensions, at approximately 24 inches wide by 24 inches deep by 33 inches high, but may differ in their tub capacity.
As of 2015, LG markets three compact washer and dryer combination units with a cubic-feet capacity of 2.3. EdgeStar markets four models with a cubic-feet capacity of 2.0, and Haier markets one model with a cubic-feet capacity of 1.8.
These all-in-one washer and dryer units use a condensing system to dry laundry. This eliminates the need for outside venting and the relevant vent hose.
