Here is the challenge I ran into trying to cool a humid upstairs bedroom last summer, a plain window AC kept the temperature down but the room still felt sticky and damp no matter how low I set the thermostat. That is because straight cooling and actual moisture removal are not automatically the same thing, and a lot of budget window units barely touch humidity even while running constantly. Once I started specifically shopping for units with a genuine dedicated dehumidifier mode rather than just incidental moisture removal as a side effect of cooling, the difference in how the room actually felt was significant.
Here is my full rundown of the best window air conditioner with dehumidifier for 2026, covering only units that confirm an actual dehumidifier mode or function rather than window ACs that just cool without addressing humidity directly.
1. Midea 6,000 BTU Window Air Conditioner, 3-in-1 Cool/Fan/Dehumidifier
This Midea EasyCool unit was my starting point for a smaller bedroom, and the dedicated dehumidifier mode genuinely made a difference on a muggy night compared to running cool mode alone. Covering up to 250 square feet, it handled a standard bedroom without trouble, and the 52dB low mode noise level kept it from being disruptive overnight. The removable, reusable filter made maintenance simple, protecting against dust and pet hair buildup over a full season of use.
Pros:
- Dedicated dehumidifier mode separate from standard cooling
- Quiet 52dB low mode operation suitable for bedrooms
- Removable, reusable filter simplifies maintenance
- Eco mode and EasyTimer help manage energy costs
Cons:
- Limited to 250 square feet, not suited for larger rooms
- Mechanical screwdriver installation required, not entirely tool free
- No heating function for cooler months
2. Midea 8,000 BTU Smart Inverter Air Conditioner with Heat and Dehumidifier
Stepping up to this Midea inverter model gave me both stronger dehumidification and genuine energy savings, with the variable-speed inverter technology delivering up to 35 percent savings compared to the Energy Conservation Standard in testing. The five mode LED display made switching between Heat, Auto, Cool, Dry, and Fan straightforward, and at 45 dBA it was noticeably quieter than the standard 6,000 BTU model.
Pros:
- Inverter technology delivers up to 35 percent energy savings
- Five distinct modes including a dedicated Dry mode for dehumidification
- Quieter operation at 45 dBA than non-inverter competitors
- Wireless app and voice control through Alexa and Google Assistant
Cons:
- Heat pump function only works above 41°F outside temperature
- Heavier at nearly 56 pounds
- Requires a wider window opening of 24 to 38.5 inches
3. Midea 12,000 BTU Window Air Conditioner with Heat
For a larger room where the 8,000 BTU Midea would be undersized, this 12,000 BTU version covers up to 550 square feet while keeping the same dehumidification performance during summer months. The CEER of 13.3 is a genuinely strong efficiency number to compare against competitors, and the UL Listed, Energy Star certified rating backs up the energy savings claims with independent verification.
Pros:
- Covers up to 550 square feet with strong dehumidification performance
- CEER of 13.3, a genuinely high efficiency rating
- UL Listed and Energy Star certified for verified performance
- Auto shutoff and defrost control protect the unit during extended use
Cons:
- Heat pump function stops working below 41°F outside temperature
- Heavier unit at nearly 58 pounds
- Wider window opening required at 24 to 38.5 inches
4. Frigidaire 6,000 BTU Window Air Conditioner and Dehumidifier
This Frigidaire unit’s dehumidification rate of up to 1.3 pints per hour is a concrete, comparable number that many competing listings simply do not disclose, which made it easier to judge against alternatives on actual moisture removal capacity rather than vague marketing language. The programmable timer in half hour increments gave finer scheduling control than the hourly timers on most competitors, and Sleep Mode’s gradual temperature increase overnight kept the room comfortable without a jarring temperature swing.
Pros:
- Disclosed dehumidification rate of up to 1.3 pints per hour
- Programmable timer adjustable in half hour increments
- Sleep Mode gradually adjusts temperature for smoother overnight comfort
- Remote control includes a built-in thermostat for accurate room reading
Cons:
- Only 1 unit left in stock at the time of writing
- Covers up to 250 square feet only, not for larger rooms
- No wifi or smart home connectivity
5. LG 8,000 BTU Window Air Conditioner with Dehumidifier
LG’s build quality showed up clearly in this unit’s 4-way air deflection, which distributed cooled and dehumidified air more evenly across a medium sized room than the simpler 2-way louvers on some competitors. Covering up to 350 square feet, it handled a larger bedroom comfortably, and the slide-out washable filter combined with a filter light reminder made maintenance easy to stay on top of without guessing when cleaning was due.
Pros:
- 4-way air deflection spreads cooled, dehumidified air more evenly
- Slide-out washable filter with a light reminder for maintenance
- Auto Restart returns to previous settings after a power outage
- Quiet 54dB low mode operation
Cons:
- No wifi or app control despite the digital panel
- Heavier at 57 pounds compared to similarly sized competitors
- No heating function for cooler months
6. Keystone 23,200 BTU Window Air Conditioner with Supplemental Heat and Dehumidifier
For a genuinely large room or open layout, this Keystone unit’s 1,500 square foot coverage puts it in a different class entirely from the smaller units on this list, and the dehumidification function scales with that larger capacity. The Smart Remote actually takes the temperature reading from wherever you are sitting and signals the unit every 3 minutes for more accurate cooling than a fixed sensor on the unit itself, and the extended 4-year warranty on the sealed system beyond the standard 1-year parts and labor coverage stood out compared to shorter warranties elsewhere on this list.
Pros:
- Covers up to 1,500 square feet, by far the largest capacity on this list
- Smart Remote takes room temperature readings for more accurate cooling
- Extended 4-year warranty on the sealed system beyond standard coverage
- Supplemental heating alongside cooling and dehumidification
Cons:
- Requires a 230V outlet, not a standard household circuit
- Heaviest unit on this list at over 121 pounds
- Supplemental heat only works between 23 and 76 degrees outside, not a primary heat source
7. Midea 8,000 BTU Window Air Conditioner, Electronic Control
This is a more streamlined, budget-conscious version within Midea’s 8,000 BTU lineup, keeping the core 3-in-1 cooling, dehumidifying, and fan functionality while trimming some of the premium features found on the inverter model. The 24-hour timer and Sleep Mode still deliver genuine personalized comfort and energy savings, and SmartHome app control alongside smartwatch and voice assistant compatibility rounds out a genuinely capable feature set for the price point.
Pros:
- Core 3-in-1 cooling, dehumidifying, and fan modes at a lower price than the inverter version
- SmartHome app, smartwatch, and voice assistant control
- Washable filter removes, cleans, and reattaches easily
- Bright LED display for easy monitoring
Cons:
- Not an inverter model, so energy savings are lower than the premium Midea option
- No heating function
- Standard 1-year warranty only
8. Whirlpool 5,000 BTU Window Air Conditioner & Dehumidifier
For the smallest room on this list, this Whirlpool unit’s 1.1 pints per hour dehumidification rate is disclosed clearly, again making direct comparison against competitors straightforward rather than guesswork. The 8-way directional air louvers gave more precise airflow control than the basic 2-way louvers found on some other small units, and the Clean Alert feature reminded me exactly when filter maintenance was due rather than leaving it to guesswork.
Pros:
- Disclosed dehumidification rate of 1.1 pints per hour
- 8-way directional air louvers for precise airflow control
- Clean Alert feature takes the guesswork out of filter maintenance
- Auto Restart after power outages
Cons:
- Covers only up to 150 square feet, suited for a small room only
- Mechanical rotary controls only, no digital display or remote thermostat
- Only 2 fan speeds compared to 3 on similarly priced competitors
9. Frigidaire 12,000 BTU Smart Inverter Window Air Conditioner with Dehumidifier
I want to flag something before recommending this one, the listing shows only 1 unit left in stock and lists the condition as Used, so confirm both details directly before ordering if a new unit matters to you. Setting that aside, the 6-way multidirectional airflow in fan mode circulated air more thoroughly than most competitors, and covering up to 550 square feet made it a strong option for a larger bedroom or small home office alongside genuine wifi and smart home integration through Alexa and Google Home.
Pros:
- Covers up to 550 square feet with 6-way multidirectional airflow
- Wifi enabled with Alexa and Google Home compatibility
- Programmable 24-hour timer plus dedicated Sleep Mode
- Smart inverter technology for efficient operation
Cons:
- Listing shows Used condition with only 1 unit left in stock, confirm before ordering
- Higher price point relative to similarly sized new competitors
- No heating function
10. DELLA 6,000 BTU Energy Saving Window Air Conditioner
The GEO Location feature on this DELLA unit was something I had not seen on any other window AC on this list, letting the Della+ app automatically adjust settings based on your phone’s location, a genuinely useful automation for anyone who forgets to turn the unit off before leaving. The CEER of 11.0 is a solid, disclosed efficiency number, and at just 38.6 pounds it was one of the lighter units in its BTU class for installation.
Pros:
- GEO Location feature automates settings based on your phone’s location
- Disclosed CEER of 11.0 for straightforward efficiency comparison
- Lightweight at 38.6 pounds for its BTU class
- Alexa compatible with the Della+ app for remote control
Cons:
- Covers only up to 250 square feet
- Newer brand with less established long-term reliability track record than Midea or LG
- Standard 1-year warranty
11. Keystone 6,000 BTU Window Mounted Air Conditioner & Dehumidifier
This Keystone unit’s disclosed 1.5 pints per hour moisture removal rate was the highest among the smaller 6,000 BTU units on this list, giving it a real edge for anyone specifically prioritizing dehumidification over raw cooling power in that size class. The same Smart Remote technology from Keystone’s larger 23,200 BTU unit carried over here, taking room temperature readings and signaling the unit every 3 minutes for accurate cooling, and the 49dB noise level was among the quietest of the compact units compared.
Pros:
- Highest disclosed dehumidification rate among 6,000 BTU units on this list at 1.5 pints per hour
- Smart Remote takes accurate room temperature readings
- Quiet 49dB operation suited for bedrooms
- Extended 4-year warranty on the sealed system
Cons:
- Covers only up to 250 square feet
- No wifi or app control
- No heating function
12. DELLA 10,000 BTU Energy Saving Window Air Conditioner
This is the larger sibling to the DELLA 6,000 BTU unit on this list, covering up to 450 square feet while keeping the same GEO Location automation and Della+ app control. The CEER of 10.9 is close to its smaller sibling’s efficiency rating, and the compact 18.58 by 17.32 by 13.31 inch footprint kept it from feeling bulky despite the larger cooling capacity.
Pros:
- Covers up to 450 square feet with the same GEO Location automation
- Compact footprint despite the larger 10,000 BTU capacity
- Alexa compatible with remote and app control
- Complete installation accessories included
Cons:
- No listed warranty information in this specific listing
- No heating function
- 54dB noise level is higher than the smaller DELLA sibling
13. Whirlpool 15,000 BTU Window Air Conditioner with Dehumidifier
For a genuinely large room, this Whirlpool unit’s 3.5 pints per hour dehumidification rate is the highest disclosed rate among the 115V units on this list, and covering up to 700 square feet made it a strong alternative to the 230V Keystone unit for anyone who does not have access to a 230V outlet. The 8-way directional air louvers matched the smaller Whirlpool 5,000 BTU unit’s airflow control, scaled up for a larger space.
Pros:
- Highest disclosed dehumidification rate among 115V units at 3.5 pints per hour
- Covers up to 700 square feet on standard household power
- 8-way directional air louvers for precise airflow control
- Eco mode and Sleep mode for energy management
Cons:
- Only 1 unit left in stock at the time of writing
- Heavy at nearly 106 pounds, installation is a two person job
- Requires a taller window opening with a 19 inch minimum height
14. KeplerX 8,000 BTU Inverter Window Air Conditioner, 50 Pint True Dehumidifier
This KeplerX unit stood out as the most dehumidification-focused option on the entire list, with a dedicated 50 pint per day true dehumidifier mode that operates independently from cooling to avoid overcooling a room on a humid but mild day. The full continuous drainage system meant I never had to manually empty a water tank, and at 44.5 dB it was among the quietest units compared, backed by Energy Star certified inverter technology.
Pros:
- Dedicated 50 pint per day true dehumidifier mode independent from cooling
- Full continuous drainage system, no manual tank emptying required
- Quiet 44.5 dB operation with Energy Star certified inverter technology
- Smart control through app, Alexa, remote, and touch panel
Cons:
- Covers only up to 350 square feet for cooling
- Newer brand with less established track record
- Auto defrost and child lock add complexity some users may not need
Final Thoughts
If dehumidification is your top priority rather than an afterthought, the KeplerX with its dedicated 50 pint true dehumidifier mode and the Whirlpool 15,000 BTU with its disclosed 3.5 pints per hour rate stand out specifically for moisture removal performance. For a smaller room, the Frigidaire and Whirlpool 5,000 and 6,000 BTU options give you clearly disclosed dehumidification rates rather than vague marketing claims, which makes comparison shopping easier. And if you need to cover a genuinely large space, the Keystone 23,200 BTU is in a category of its own, though it requires a 230V outlet most homes do not have in every room. Whichever you choose, look specifically for a disclosed pints-per-hour or pints-per-day dehumidification figure rather than assuming any window AC handles humidity the same way.
