The best high capacity washer and dryers combo for apartments is usually a ventless 5.0-cubic-foot all-in-one such as the LG WM6998HBA or GE Profile UltraFast Combo, provided your laundry area has enough depth and a compatible 120-volt outlet; smaller apartments may be better served by a 24-inch compact washer-dryer pair.
Quick picks by apartment situation
| Apartment situation | Best fit | Why it makes sense | Main compromise |
|---|---|---|---|
| Maximum capacity without a vent | LG WM6998HBA | About 5.0 cu. ft., ventless heat-pump drying, one 27-inch cabinet | Deep cabinet and relatively long drying cycles |
| Large household and frequent laundry | GE Profile UltraFast Combo PFQ97HSPV | About 5.0 cu. ft., automatic load sensing and continuous wash-and-dry operation | Requires substantial floor depth and careful door clearance |
| Premium features and a large drum | Samsung Bespoke AI All-in-One Combo | Roughly 5.3 cu. ft. capacity in a ventless heat-pump design | Check the exact model’s electrical, depth, and service requirements |
| Very narrow closet or lower laundry demand | 24-inch compact ventless combo or stacked pair | Usually about 2.4–2.6 cu. ft. and easier to fit through doors | Cannot match the usable load size of a full-size 5.0-cu.-ft. drum |
What “high capacity” really means in an apartment
A listed capacity describes the drum’s total volume, not the amount of clothing that will dry efficiently in one pass. A 5.0-cu.-ft. machine can wash a large family load, but a densely packed load may need extra drying time. Towels, denim, and bedding also need room to tumble, so the practical drying capacity can feel smaller than the headline number.

View on AmazonFor one or two people, 3.5–4.5 cu. ft. is often sufficient. A 5.0-cu.-ft. combo becomes more useful when you wash bulky bedding, do laundry only once or twice a week, or want a complete load to wash and dry while you are away. Do not select capacity by itself: a large drum in a deep closet is not a successful installation.
Head-to-head: the major full-size ventless combos
LG WM6998HBA
The LG WM6998HBA is a strong choice when you want a full-size all-in-one with no exterior dryer vent. It offers approximately 5.0 cu. ft. of capacity in a cabinet about 27 inches wide. Its heat-pump drying system recirculates warm air rather than exhausting it through a wall, which suits apartments where a vent cannot be added.
The advantage is installation flexibility: you generally need a water supply, drain, and grounded 120-volt receptacle, not a 240-volt dryer circuit. The tradeoff is time. A complete wash-and-dry program can take several hours, particularly with heavy fabrics or a nearly full load. The machine is also roughly 33 inches deep before allowing extra clearance for hoses, the door, and ventilation around the cabinet.
GE Profile UltraFast Combo PFQ97HSPV
The GE Profile UltraFast Combo PFQ97HSPV is another approximately 5.0-cu.-ft. full-size ventless model, measuring about 28 inches wide, 39 inches high, and 32 inches deep. It is attractive for households that want to put in a load and leave without transferring wet clothes between machines.
Its automatic wash-and-dry operation is convenient for routine clothing, but the same limitation applies to most single-drum combos: laundry throughput is slower than with separate appliances. A household washing several loads on a weekend may prefer a stacked washer and dryer, because one load can dry while the next washes. The GE also needs a solid, level floor; vibration becomes more noticeable in a closet with flexible flooring or an unlevel platform.
Samsung Bespoke AI All-in-One Combo
Samsung’s Bespoke AI All-in-One Combo is aimed at shoppers who want one of the largest available ventless drums, at roughly 5.3 cu. ft. depending on the specific model. The extra volume is useful for comforters and large clothing loads, although it does not eliminate the need to avoid overloading during drying.
Because Samsung sells multiple configurations and regional variants, verify the full model number before ordering. Confirm cabinet depth, door swing, electrical requirements, drain arrangement, and whether the listed installation kit is included. A product advertised as “ventless” still produces condensate and needs a proper drain connection; ventless does not mean installation-free.
Dimensions and hookup requirements compared
| Machine type | Typical capacity | Typical width | Typical depth | Power and plumbing |
|---|---|---|---|---|
| Full-size ventless combo | 4.5–5.3 cu. ft. | 27–28 in. | 32–34 in. | 120 V, cold-water supply, drain |
| 24-inch compact ventless combo | 2.4–2.6 cu. ft. | 23.5–24 in. | 25–27 in. | 120 V, usually cold-water supply, drain |
| Stacked separate washer and electric dryer | Washer commonly 4.5–5.0 cu. ft. | 27–28 in. | 30–34 in. | Often 240 V for dryer, two appliances, drain |
Dimensions in listings usually describe the cabinet, not the installed footprint. Add at least 1 inch at the sides where the manufacturer permits, 2–4 inches behind the unit for hoses and power, and enough front space for the door to open fully. Measure the narrowest hallway, doorway, elevator entrance, and closet opening—not just the final alcove.
Venting, drains, and apartment approval
Ventless combos are usually the easiest high-capacity option for apartments because they do not require a 4-inch exhaust duct. They still need a water inlet and drain hose. The drain must be secured at the manufacturer’s specified height; an incorrectly positioned hose can cause siphoning, slow draining, or leaks.
Some apartment laundry closets have only a two-prong outlet, a shared circuit, or a receptacle controlled by a wall switch. Do not use an extension cord or power strip. Have an electrician install a properly grounded receptacle if necessary. Also check the lease or building rules before replacing an appliance, especially in a high-rise where leak pans, shutoff valves, or licensed installation may be required.
Cycle time and laundry throughput
A combo saves space and eliminates transfers, but it does not necessarily save time. A normal wash-and-dry load may take roughly 2.5–4.5 hours, with bulky fabrics taking longer. Separate machines can often finish two loads in the time one overloaded combo takes to wash and dry.
Consider this simple example: if your household produces four loads per week and a combo averages 3.5 hours per complete load, the machine may run about 14 hours weekly. That is reasonable if laundry runs overnight or while you are out. If you need eight loads every weekend, a separate stacked pair may be the better space-efficient solution despite its larger hookup requirements.
Installation checklist before buying
- Measure width, height, depth, doorway clearance, and the full door-swing area.
- Locate the water shutoff, drain standpipe or approved drain connection, and grounded outlet.
- Confirm whether the floor can support the appliance without rocking or excessive vibration.
- Check that the building permits a new appliance and identify who is responsible for leak protection.
- Leave access to the filter, drain pump, detergent drawer, and rear connections.
- Verify delivery dimensions and whether old-appliance removal is available in your building.
Ownership realities: what wears first
The door gasket, drain filter, pump, and detergent drawer typically need more attention than the drum itself. Wipe the gasket after damp cycles, leave the door ajar, and run the manufacturer’s cleaning cycle at the recommended interval. Remove lint and debris from the accessible filter; a clogged filter can cause poor draining and longer drying.
Use the recommended low-sudsing detergent and measure it rather than filling the drawer automatically. Excess detergent leaves residue, creates odors, and may require additional rinsing. Do not pack the drum tightly with towels or leave wet laundry inside overnight. Heat-pump systems are efficient but depend on clean airflow paths and patient drying times.
Bottom line
Choose the LG WM6998HBA or GE Profile PFQ97HSPV when you want near-5.0-cu.-ft. capacity, a 120-volt installation, and no exterior vent. Choose the larger Samsung option when drum volume is the priority and its exact installation specifications fit your space. If your closet is under 27 inches wide or your household runs many loads in succession, a compact combo or stacked separate machines may be more usable than the biggest drum available.
