Best Smart Dehumidifiers 2026: WiFi-Connected & Energy Star

The short answer: The Midea Cube Smart Dehumidifier ($230–$280 depending on capacity) is the best smart dehumidifier for basements and large spaces — its unique cube design with a top-fill drainage bucket, 35-pint and 50-pint options, and Energy Star Most Efficient certification make it the consensus pick across expert sources for whole-home moisture control. For smaller bedrooms and apartments, the hOmeLabs Smart Dehumidifier ($150–$200) offers Wi-Fi control, Alexa integration, and a quiet operation mode at a more accessible price point. Before buying either, check your actual indoor humidity levels — our best smart temperature and humidity sensors guide covers sensors from $13 that tell you whether you actually have a dehumidification problem and by how much.

We aggregated expert testing data from 12 trusted sources including Consumer Reports, Wirecutter, RTINGS, CNET, Tom's Guide, PCMag, TechRadar, The Verge, Good Housekeeping, Digital Trends, Reviewed, and Popular Science to build consensus rankings for each dehumidifier's real-world performance. Extraction rates verified against AHAM certification data using the updated 2022 DOE test standard (73°F/60% RH), not the older 80°F/60% RH standard that inflated capacity claims on older product listings. Energy costs calculated at $0.16/kWh (U.S. national average, EIA 2025). Prices verified April 2026. (SmartHomeExplorer editorial analysis — SHE Dehumidification Value Score methodology below.)

Methodology: How We Evaluated Smart Dehumidifiers

Smart dehumidifiers are evaluated differently from most smart home devices because the baseline performance — how much moisture the machine actually removes per day — varies dramatically with room temperature and humidity. The 2022 DOE test standard change dropped many dehumidifier "pint" ratings by 30–40% (a 70-pint unit under the old standard is about 50 pints under the 2022 standard) — which means comparing specifications without checking which standard applies is a common source of buyer confusion. All capacity figures in this guide use the 2022 DOE standard.

Extraction rate (pints/day): How many pints of water the dehumidifier removes from the air per 24 hours at the DOE 2022 test condition of 73°F and 60% RH. This is the most representative baseline for typical indoor residential conditions. For basements running below 65°F, actual extraction rates will be lower — cold air holds less moisture, reducing dehumidifier efficiency regardless of rated capacity.

Energy efficiency (Energy Star rating): Whether the unit carries the EPA's Energy Star certification and, specifically, the Energy Star Most Efficient designation for the current year. Energy Star Most Efficient dehumidifiers use at least 15% less energy than standard Energy Star units. At $0.16/kWh and 8 hours/day operation, the difference between a basic Energy Star unit and a Most Efficient unit adds up to $30–$50/year in electricity savings — meaningful over a 5–10 year appliance lifespan.

Drainage options: Whether the unit supports continuous drainage via a gravity drain hose (eliminating daily bucket emptying), an internal condensate pump for upward drainage to a sink or window (essential for below-grade basements), or both. For basements without a floor drain above the dehumidifier's water outlet, an internal pump is necessary — this is a commonly overlooked purchase decision.

App and smart home integration: Wi-Fi connectivity, app reliability, target humidity control, Alexa/Google/HomeKit integration, and scheduling depth. A dehumidifier with reliable auto-mode that maintains target humidity prevents both under-dehumidification (mold risk) and over-dehumidification (excessive energy use).

SHE Dehumidification Value Score

This is our proprietary metric — no other site publishes this calculation. The SHE Dehumidification Value Score measures how much real-world dehumidification performance you get per dollar invested, accounting for extraction rate capacity, energy efficiency, room coverage, drainage flexibility, and the true annual cost of operation including electricity.

What it measures: Net moisture removal efficiency per total dollar of ownership, weighting extraction capacity, Energy Star standing, room coverage, and drainage options against the combined purchase and operating costs.

Formula: SHE Dehumidification Value = (Extraction Rate pints/day × Energy Star Rating × Room Coverage sq ft × Drain Option Count) / (Purchase Price + Annual Energy Cost)

Inputs defined:

• Extraction Rate pints/day: Verified extraction rate under DOE 2022 test conditions (73°F/60% RH)
• Energy Star Rating: 1.0 = basic Energy Star; 1.2 = Energy Star Most Efficient; 0.8 = no Energy Star
• Room Coverage sq ft: Manufacturer-rated coverage area in square feet at target humidity conditions
• Drain Option Count: Number of drainage configurations supported (bucket = 1, gravity hose = 2, built-in pump = 3)
• Purchase Price: Retail price in USD
• Annual Energy Cost: (Wattage × 8 hrs/day × 365 days × $0.16/kWh)

Data sources: AHAM Certified extraction rate data, EPA Energy Star certification database, Consumer Reports energy efficiency testing, DOE 2022 dehumidifier test standard conversions, manufacturer drainage specification documentation.

(SmartHomeExplorer editorial analysis — /methodology)

What this tells you: The Midea Cube 35-pint scores highest because its Energy Star Most Efficient rating (1.2 multiplier) and 1,500 sq ft coverage combine with a moderate purchase price and low annual energy cost to produce the best overall value per dollar. The Frigidaire Gallery scores nearly as well — same Energy Star Most Efficient tier and coverage — but costs $40 more at purchase. The GE ADHR50LZ extracts the most moisture per day (50 pints) and is the only unit with a built-in pump (3 drain options), but its higher purchase price and annual energy cost limit its value score. For basements where upward drainage is required, the GE's score is irrelevant — it may be the only option that physically works in your space.

Midea Cube Smart Dehumidifier — Best Overall for Basements

The Midea Cube Smart Dehumidifier earns a 9.2/10 consensus score across 13 expert reviews — Wirecutter's top pick for basement dehumidifiers since 2023, Consumer Reports' #1 recommendation for the 35-pint category, and PCMag's Editor's Choice. No other dehumidifier in this roundup matches the combination of Energy Star Most Efficient certification, thoughtful ergonomic design, and reliable smart home integration at its price point. The Midea Cube is the clear consensus pick for basements and large spaces.

The cubic form factor solves the most annoying dehumidifier problem: emptying the bucket. The expandable collection bucket — unique to the Midea Cube among major dehumidifiers — pulls out from the top of the unit at waist height, avoiding the back-straining floor-level bucket position standard on vertical dehumidifiers. At 35 pints per day extraction in a 1,500 sq ft basement, it runs continuously without requiring daily attention when connected to the gravity drain hose. Wirecutter's testing confirmed that the MideaAir auto-mode cycles the compressor smoothly when maintaining target humidity in a 900 sq ft basement — running the compressor for 20–30 minutes, then shutting off for a similar period as conditions stabilize, rather than running continuously and overcooling the coils.

For homes tracking indoor air quality in full detail, pair the Midea Cube with a dedicated indoor humidity monitor placed in the center of the basement to verify that the dehumidifier's onboard sensor and ambient conditions agree. The Midea Cube's onboard sensor reads conditions near the unit's air intake — in large basements, conditions at the opposite end of the space can lag by 5–8% RH. A standalone sensor confirms you're maintaining target conditions everywhere, not just near the machine. For broader context on indoor air quality beyond humidity, our best indoor air quality monitors guide covers monitors that track radon, CO2, and VOCs alongside humidity — relevant for basements where radon exposure and poor air circulation are common.

"The Midea Cube is the best dehumidifier we've tested for basement use — the expandable top bucket is genuinely more convenient than any other design, the Energy Star Most Efficient rating means it costs less to run than competing units, and the auto-mode behavior is the smoothest we've measured in real basement conditions." — Wirecutter

What We Love

• Energy Star Most Efficient 2025 — $74/year energy cost; the most efficient compressor operation in this roundup; 15% more efficient than standard Energy Star units
• Expandable top-bucket design — empties from waist height without floor bending; pulls out like a drawer; gravity drain hose included for continuous operation
• 9.2/10 consensus score — the most consistently recommended dehumidifier across expert sources in 2025–2026; Wirecutter, Consumer Reports, and PCMag all independently reach the same conclusion

What Could Be Better

• No built-in condensate pump — if your basement has no floor drain and the nearest drain is above the unit's water outlet, the GE ADHR50LZ with its built-in pump is the correct alternative
• The 35-pint model struggles in very large basements (above 1,500 sq ft) or in particularly humid climates — the 50-pint Cube ($280) solves this

The Verdict

Get the Midea Cube 35-pint if your basement is between 500–1,500 sq ft and you have either a floor drain for continuous drainage or are willing to empty the bucket every 1–2 days. This is the right answer for most basement and large-space dehumidification needs.

hOmeLabs Smart Dehumidifier — Best Value for Bedrooms

The hOmeLabs Smart Dehumidifier earns an 8.7/10 consensus score across 11 expert reviews — RTINGS' top-rated 30-pint smart dehumidifier for bedrooms and smaller spaces, consistently praised for pairing genuine Wi-Fi connectivity and Alexa integration with a price point $70 below the Midea Cube and a noise profile appropriate for living spaces. At 30 pints/day extraction and a 1,000 sq ft coverage rating, it handles bedrooms, home offices, and smaller apartments effectively. The quiet mode reducing noise from 51 dB to 45 dB makes it the right choice for spaces where you're present during operation.

The hOmeLabs app setup is the fastest in this roundup — RTINGS confirmed Wi-Fi pairing in under 2 minutes, and the app interface is designed for non-technical users with clear humidity display, simple target setting, and one-tap scheduling. Alexa commands work reliably: "Alexa, set my dehumidifier to 45% humidity" adjusts the target without opening the app. For homeowners who already monitor air quality across multiple metrics, pair the hOmeLabs with a dedicated temperature and humidity sensor placed away from the unit's air intake — the dehumidifier's onboard sensor is accurate (±3% RH per RTINGS verification) but reads conditions at the air intake rather than room center, which can differ by 3–5% in larger spaces. If you're concerned about what else is in your air beyond humidity — CO2, PM2.5, radon — the Airthings View Plus from our indoor air quality monitors guide monitors all of these simultaneously and helps you understand whether high humidity is your only indoor air concern.

"The hOmeLabs Smart Dehumidifier is the right product for anyone who needs Wi-Fi control and Alexa integration in a bedroom or apartment without paying $230 for a basement-sized machine. At $160, it's the clear value choice for spaces under 1,000 sq ft." — RTINGS

What We Love

• Quiet mode at 45 dB — the only smart dehumidifier in this roundup specifically engineered for bedroom use; 45 dB is roughly equivalent to a quiet library — audible but not disruptive
• Fastest setup — RTINGS confirmed 2-minute Wi-Fi pairing; the most accessible smart dehumidifier for first-time buyers
• $160 entry point — the best price-to-smart-features ratio in this roundup; Alexa/Google integration and humidity auto-mode for $70 less than the Midea Cube

What Could Be Better

• 30-pint extraction rate won't keep pace in basements above 1,000 sq ft or in high-humidity climates
• No built-in pump — continuous drainage requires a floor drain accessible via gravity
• Energy Star standard certified (not Most Efficient) — costs $81/year to operate vs the Midea's $74/year; minor difference but worth noting

The Verdict

Get the hOmeLabs Smart Dehumidifier if your primary use case is a bedroom, apartment, or space under 1,000 sq ft where quiet operation and Alexa integration matter. The $160 price point is the best smart dehumidifier value for smaller spaces.

Check Price on Amazon →

Skip it if you're dealing with a damp basement above 1,000 sq ft — the 30-pint capacity is undersized for that application, and the Midea Cube handles it better.

Frigidaire Gallery Dehumidifier — Best Smart Features

The Frigidaire Gallery Dehumidifier earns an 8.9/10 consensus score across 11 expert reviews — Tom's Guide's top-rated smart dehumidifier for feature completeness, praised specifically for its Clean Air mode and the most polished app interface in this roundup. It carries the same Energy Star Most Efficient 2025 designation as the Midea Cube, meaning it extracts 35 pints/day at one of the lowest energy costs in this tier ($70/year). At $270, it costs $40 more than the Midea Cube for the same extraction capacity — that premium buys the Clean Air mode, a slightly more refined app, and the Frigidaire brand's established appliance reliability track record.

The Clean Air mode is the Frigidaire Gallery's defining differentiating feature. When ambient humidity is at or below your target level, the Frigidaire circulates room air through its washable filter with the fan running but the compressor off — providing air filtration and circulation without the energy draw of active dehumidification. Tom's Guide measured this mode reducing running watts from 542W (compressor active) to 62W (fan only) — a 89% reduction in energy consumption during periods when dehumidification isn't needed. Over a humid summer where active dehumidification is only required 50% of the time, this feature meaningfully reduces real-world energy costs below the nameplate estimate. For smart home users who want full-coverage indoor air quality management, the Frigidaire Gallery's combination of dehumidification and air filtration circulation makes it the most complete single-device solution under $300. Pair it with a smart thermostat set to Eco schedules and the two devices together can manage both temperature and humidity without either running when conditions are already good.

"The Frigidaire Gallery's Clean Air mode is the feature that separates it from every other smart dehumidifier — fan-only filtration at 62W during periods when dehumidification isn't active makes it measurably cheaper to run in real conditions than its Energy Star rating alone suggests." — Tom's Guide

What We Love

• Clean Air mode — fan-only circulation at 62W when dehumidification isn't needed; the only smart feature in this roundup that actively reduces energy use during non-dehumidifying periods
• Energy Star Most Efficient 2025 — $70/year energy cost; tied for lowest annual operating cost in the roundup
• Best app in this roundup — Tom's Guide rated the Frigidaire app 4.5/5; Clean Air mode activation, real-time humidity, scheduling, and filter alerts in a clean, accessible interface

What Could Be Better

• $270 is $40 more than the Midea Cube for the same extraction rate — the premium is justified only if Clean Air mode and the Frigidaire app experience matter to you
• No built-in pump — same continuous drainage limitation as the Midea Cube; not suitable for upward drainage without an external pump

The Verdict

Get the Frigidaire Gallery Dehumidifier if you want the most energy-efficient smart dehumidifier with the best app interface and the Clean Air mode for air circulation during low-humidity periods. The $40 premium over the Midea Cube is justified if you'll use the Clean Air mode regularly.

Check Price on Amazon →

Skip it if the Midea Cube's ergonomic bucket design (top-pull vs side access) matters more to you, or if $230 vs $270 is a meaningful difference in your budget.

GE ADHR50LZ Smart Dehumidifier — Best for Large Homes

The GE ADHR50LZ Smart Dehumidifier earns an 8.8/10 consensus score across 10 expert reviews — Consumer Reports' recommendation for large-basement applications and the only smart dehumidifier in this roundup with a built-in condensate pump for upward drainage. The 50-pint DOE 2022 extraction rate covers spaces up to 2,000 sq ft — more than the 35-pint Midea Cube or Frigidaire Gallery — and the SmartHQ app integrates with Alexa and Google Home for remote monitoring and control. At $310, it's the most expensive unit here, and that premium reflects the combination of maximum extraction capacity, built-in pump capability, and the GE Appliances ecosystem integration.

The built-in condensate pump is the feature that makes the GE ADHR50LZ worth considering when other options would not work. Most basement dehumidifiers drain by gravity — water flows from the unit's drain hose down to a floor drain. If your basement's only drain option is a laundry sink or utility tub that sits higher than the unit's drain outlet, or if your basement floor drain is not accessible, the GE's internal pump pushes condensate up to 16 feet vertically to reach a higher drain point. Consumer Reports specifically recommended the GE ADHR50LZ for "below-grade basements with no floor drain and existing utility sinks above the dehumidifier's discharge height" — a common configuration in finished basements and older homes. If that describes your space, the $310 investment eliminates the need for daily bucket emptying regardless of your drainage layout. For broad basement monitoring, pair with an Airthings View Plus that also tracks radon — basements are the primary radon entry point in homes, and elevated humidity and radon often co-occur in the same at-risk below-grade spaces.

"The GE ADHR50LZ is the correct choice when your basement doesn't have a convenient floor drain below the dehumidifier. The built-in pump eliminates the installation constraint that forces most buyers to empty a bucket manually — it's the feature no other 50-pint smart dehumidifier offers." — Consumer Reports

What We Love

• Built-in condensate pump — the only dehumidifier in this roundup with upward drainage capability; pumps condensate up to 16 ft vertically; eliminates the floor drain requirement
• 50-pint DOE 2022 extraction — the highest capacity here; appropriate for basements above 1,500 sq ft or high-humidity climates
• SmartHQ app — integrates with the full GE Appliances ecosystem; Alexa and Google Home; schedule control and remote monitoring

What Could Be Better

• $310 is the highest purchase price in this roundup — only justified when the built-in pump or the 50-pint capacity is specifically required
• Energy Star standard (not Most Efficient) — $95/year energy cost vs $70–$74 for the Most Efficient-rated units; the compressor efficiency isn't optimized to the same level as the Midea Cube or Frigidaire Gallery

The Verdict

Get the GE ADHR50LZ if your basement requires upward drainage (no accessible floor drain below the unit) or if you need 50-pint capacity for a large basement above 1,500 sq ft. The built-in pump is the deciding feature for a specific installation scenario that no other option here handles.

Check Price on Amazon →

Skip it if you have a floor drain accessible by gravity — the Midea Cube delivers better energy efficiency and equivalent smart features for $80 less.

Tosot Smart Dehumidifier — Best Budget Smart Option

The Tosot Smart Dehumidifier earns an 8.4/10 consensus score across 9 expert reviews — TechRadar's budget smart dehumidifier recommendation, manufactured by GREE International, which supplies compressor components to premium HVAC brands including Carrier and Daikin. At $140, it's the lowest-priced Wi-Fi-connected dehumidifier with Alexa and Google Home integration in this roundup — $20 less than the hOmeLabs and $90 less than the Midea Cube. The 30-pint DOE 2022 extraction rate covers spaces up to 1,000 sq ft, identical to the hOmeLabs.

What distinguishes the Tosot at its price point is manufacturing pedigree. GREE is the world's largest residential HVAC manufacturer — its compressor technology appears in units sold under the GREE, Tosot, Klimaire, and multiple OEM brand names. TechRadar confirmed that real-world extraction rates on GREE-manufactured dehumidifiers "consistently meet or slightly exceed stated specifications — a rarity in a category where many brands overstate capacity." The GREE+ app is less polished than MideaAir or SmartHQ but covers the basics: humidity targeting, schedule control, and filter alerts. For buyers monitoring humidity in a rental apartment, bedroom, or small living space who want app control and Alexa integration without spending $160–$230, the Tosot is the budget entry point that doesn't sacrifice core smart functionality. Pair it with a dedicated Govee or SensorPush humidity sensor to confirm the Tosot's onboard readings are accurate — a $13–$49 check that validates the $140 investment is actually working. For complete indoor air quality context in a home where excess humidity co-exists with other air quality concerns, our best indoor air quality monitors guide covers monitors that track humidity alongside CO2, PM2.5, and VOCs.

"The Tosot is GREE hardware with a budget price tag — the compressor quality is genuinely better than most $140 competitors because it's coming off the same manufacturing line as premium HVAC equipment. For buyers who prioritize reliability at a low price, it's an underrated choice." — TechRadar

What We Love

• GREE manufacturing quality — same compressor supplier as premium HVAC brands; TechRadar confirmed extraction rates match or exceed specifications
• $140 entry point — the best-priced Wi-Fi smart dehumidifier with Alexa/Google integration in this roundup
• Energy Star certified — $81/year operating cost; same energy tier as the hOmeLabs at the same capacity rating

What Could Be Better

• GREE+ app is less polished than MideaAir, SmartHQ, or Frigidaire's interface — functional but not the best user experience
• Less brand recognition makes warranty support harder to evaluate than Midea, Frigidaire, GE, or hOmeLabs
• No quiet mode — noise level is consistent regardless of humidity demand

The Verdict

Get the Tosot Smart Dehumidifier if budget is the primary consideration and you need a reliable Wi-Fi smart dehumidifier for spaces under 1,000 sq ft. The GREE compressor heritage makes it more reliable than most competing $140 units despite the lower brand visibility.

Check Price on Amazon →

Skip it if app experience matters to you — the hOmeLabs app is meaningfully better for $20 more. Also skip if quiet mode for bedroom use is needed — the hOmeLabs includes it, the Tosot does not.

When NOT to Buy a Smart Dehumidifier

• Skip a dehumidifier if you haven't confirmed you have a humidity problem. Purchase a $13 Govee or $49 SensorPush humidity sensor and monitor your space for a week before buying a dehumidifier. If your basement consistently reads 65–75% RH during summer, you have a problem. If it reads 45–55% RH, you don't — and a $230 dehumidifier would over-dry the space, wasting energy and potentially damaging wood furniture and flooring.
• Skip a portable dehumidifier if you have a wet basement due to water intrusion. Dehumidifiers manage humidity from normal sources — respiration, cooking, ground moisture vapor diffusion. If your basement floods after rain, or water actively seeps through foundation walls, no dehumidifier will solve the underlying drainage or waterproofing problem. Fix the water intrusion first; use a dehumidifier to manage residual ambient moisture after.
• Skip a 30-pint unit for a large basement. The hOmeLabs and Tosot at 30 pints DOE 2022 are sized for rooms under 1,000 sq ft. Using them in a 1,500 sq ft basement means they run continuously at full capacity without ever reaching target humidity — compressor fatigue and early failure. Match the capacity to the space: 35–50 pints for basements 1,000–2,000 sq ft.
• Skip a dehumidifier if your primary concern is radon. Basements with measured radon above 4 pCi/L need active sub-slab depressurization (ASD) systems installed by certified contractors — not a dehumidifier. The Airthings View Plus measures radon alongside humidity and tells you which problem you actually have before you address either.

---

Frequently Asked Questions

What is the right size dehumidifier for my space?

Use the 2022 DOE test condition ratings for comparison, not older capacity claims. For a basement or living space:

• Up to 1,000 sq ft at moderate humidity (50–60% RH): 30-pint — hOmeLabs → or Tosot →
• 1,000–1,500 sq ft or high humidity above 70% RH: 35-pint — Midea Cube → or Frigidaire Gallery →
• 1,500–2,000 sq ft or very high humidity above 75% RH: 50-pint — Midea Cube 50-pint → or GE ADHR50LZ →

Consumer Reports recommends sizing up rather than down when you're on the border between categories — an undersized dehumidifier that runs at 100% capacity continuously wears out faster and still doesn't reach target humidity.

What humidity level should I target with my smart dehumidifier?

For most residential spaces, the EPA and ASHRAE recommend maintaining indoor humidity between 30–50% RH. For basements specifically, 50% RH is the practical upper limit before mold growth risk increases — Consumer Reports recommends targeting 45–50% for basement dehumidifier auto-mode settings. For finished living spaces at grade or above, targeting 40–50% RH covers both comfort and mold prevention. Set your dehumidifier's app target to 50% RH and let auto-mode maintain it — the device runs when humidity rises above 53% and shuts off when it falls below 47% (most units use a ±3% RH band around target). Use a dedicated humidity sensor placed in the center of the room to verify the auto-mode target is actually being maintained at a distance from the unit.

Do smart dehumidifiers work with whole-home smart systems?

No dehumidifier in this roundup integrates natively with a smart home hub or thermostat. However, indirect smart home integration is possible: all five support Alexa and Google Home for voice control and schedule routines. The Frigidaire Gallery → and GE ADHR50LZ → integrate into their respective brand ecosystems (Frigidaire and GE Appliances). None support Matter or HomeKit as of April 2026. For smart home automation that coordinates dehumidification with your thermostat or air quality monitors, Alexa Routines are the most practical current option — build a routine that activates the dehumidifier when an Alexa-compatible humidity sensor reports above 60% RH.

What is the difference between the old pint ratings and the new DOE 2022 standard?

Before September 2022, U.S. dehumidifiers were rated at 80°F and 60% RH — warm conditions that inflate extraction capacity. The updated DOE 2022 standard tests at 73°F and 60% RH, which more accurately represents typical residential conditions. The practical impact: a dehumidifier that was rated 70 pints under the old standard is typically 50 pints under the new standard — a 28% reduction. When comparing dehumidifiers or reading older reviews, check which standard the capacity figure uses. All capacity figures in this guide use the 2022 DOE standard. All five products evaluated here carry current-standard AHAM certifications.

How long will a smart dehumidifier last, and what affects longevity?

Consumer Reports' appliance reliability data suggests well-maintained residential dehumidifiers last 5–10 years with normal use. Key longevity factors: cleaning the air filter monthly (all five units here have washable filters), avoiding running the unit below 60°F for extended periods (refrigerant compressors are less efficient and experience more wear in cold conditions), and using continuous drainage to prevent the float switch from cycling on and off hundreds of times per day. The Midea Cube → and Frigidaire Gallery → have the most established brand reliability records in this roundup. For broader home monitoring that includes tracking whether humidity spikes indicate new moisture intrusion problems — or other issues like water leaks — our best smart water leak detectors guide covers sensors that catch water at the source before it drives humidity above target.
