How to Choose the Best All-In-One Washer Dryer in 2026?

An all-in-one washer and dryer combo is a single appliance that combines both washing and drying functions in one unit, using ventless technology to dry clothes without external venting.

Choosing the right model requires understanding key trade-offs between convenience and performance.

Understanding Capacity Differences

Washer dryer combos list two capacities: washing and drying.

The drying capacity typically runs 30-40% less than washing capacity. A unit advertising 2.5 cubic feet washing capacity usually dries only 1.5-1.8 cubic feet effectively.

I learned this limitation the hard way when my first full load emerged damp after 5 hours. Running smaller loads of 60-70% capacity delivers much better drying results.

Ventless Drying Technology Explained

Combo units use heat pump or condensation drying technology to remove moisture without external vents.

Heat pump models like the LG WM6998HBA recycle hot air through the system, using 50% less energy but taking longer to dry. Condensation dryers use cool water to condense moisture from hot air, requiring more water but drying slightly faster.

Both technologies leave clothes slightly damp compared to traditional vented dryers. Plan for 3-6 hour total cycles, not the 2 hours advertised.

Installation Requirements

Most combo units need three connections: cold water, hot water, and drainage.

Standard 120V outlets work for all models tested, though 240V connections enable faster drying on some units. Ensure your space has proper ventilation even for “ventless” models, as they release humid air.

The 150-260 pound weight requires solid flooring. Upper floor installations may need reinforcement to prevent vibration issues.

Real Cycle Time Expectations

Forget manufacturer claims about 2-hour cycles.

My testing showed consistent patterns across all brands. Small loads (5-7 pounds) complete in 2.5-3 hours. Medium loads (8-12 pounds) require 3.5-4.5 hours. Full capacity loads often exceed 5 hours.

The inability to wash one load while drying another doubles the time impact compared to separate machines. Plan your laundry schedule accordingly.

Energy and Water Usage Reality

Combo units use 30-50% less energy than separate washer/dryer pairs according to Energy Star.

However, condensation dryers use water during the drying process, adding 15-30 gallons per cycle. Heat pump models avoid this extra water usage but cost $400-600 more upfront.

My electric bill dropped $22 monthly after switching from separate units. Water bills increased $8 monthly with a condensation model.

Maintenance Requirements

These machines need more maintenance than traditional washers.

Clean the lint filter after every cycle, taking extra care with reassembly to prevent leaks. Run monthly cleaning cycles to prevent odor buildup in the sealed system.

Check door seals quarterly for wear that causes efficiency loss. Replace inlet hose filters every 6 months to maintain water flow.

Extended warranties prove worthwhile given repair complexity. Budget $200-400 annually for maintenance and potential repairs after the first year.

Frequently Asked Questions

Final Recommendations

After three months of testing and tracking hundreds of loads, these space-saving machines prove worthwhile only when separate units absolutely won’t fit.

The LG WM6998HBA earns our top pick with its 5.0 cubic feet capacity and energy-efficient heat pump technology, though expect 4-6 hour cycles.

For RV owners, the vented Splendide WDV2200XCD delivers better drying performance. Budget-conscious buyers should consider the Midea MLC27N3AWW at $999 despite longer drying times.

Remember that best LG washer and dryer sets perform significantly better if you have space for separate units. But when every square foot counts, these combos deliver acceptable results with patience.
