# The Best Large Dehumidifiers for Big Rooms and Open Floor Plans > Great rooms and open-concept spaces have more air to turn over — and people living in them. Here's how to get capacity without the racket. Canonical: https://www.enthusiastreview.com/best/best-dehumidifier-for-large-room/ Last updated: 2026-11-05 Published: 2026-10-02 Category: Size & Features Publisher: Enthusiast Review A great room, an open kitchen-dining-living space or a finished attic doesn't play by bedroom rules. There's simply more air to move, and the moisture from cooking, showers and a busy household spreads through all of it. A **large dehumidifier** — a high-capacity, 50-pint-class unit with strong airflow — is what it takes to reach the far corners of an open floor plan. But a big room is also usually a lived-in room, so capacity isn't the only thing that matters. A larger tank (or a pump) saves you from emptying a bucket three times a day, and a reasonable noise level keeps the machine from fighting the TV. Below, we've picked the best large-space dehumidifiers for different needs, from maximum coverage to a quieter option for a living area that's only moderately damp. ## Our top picks - **Best overall:** Midea Cube 50 — [check price on Amazon](https://www.amazon.com/dp/B0GL7B1FC8?tag=sktiger-20&linkCode=ll1) - **Best for extra-large spaces:** Honeywell TP70PWKNR — [check price on Amazon](https://www.amazon.com/s?k=Honeywell%20TP70PWKNR&tag=sktiger-20) - **Best value with a pump:** hOmeLabs HME1003 — [check price on Amazon](https://www.amazon.com/s?k=hOmeLabs%20HME1003&tag=sktiger-20) - **Best quiet pick:** Frigidaire FFAD2233W1 — [check price on Amazon](https://www.amazon.com/s?k=Frigidaire%20FFAD2233W1&tag=sktiger-20) The **Midea Cube 50-Pint** is the best large-room dehumidifier for most homes: strong airflow, a roomy tank in its base and a compact footprint for its capacity. ## 1. Midea Cube 50-Pint Smart Dehumidifier (MAD50S1QWT) — Best overall [Check price on Amazon](https://www.amazon.com/dp/B0GL7B1FC8?tag=sktiger-20&linkCode=ll1) **Pros** - Turbo airflow reaches the corners of open spaces - Large tank built into the base means fewer empties - Compact cube shape for its capacity - Wi-Fi app control **Cons** - No built-in pump - One-year warranty **Why we picked it:** In a big open room, a 50-pint unit pulls a lot of water fast — and that's where most dehumidifiers become a chore, because the bucket fills before dinner. The Cube's tank forms its base and holds far more than a typical pull-out bucket, so you can go much longer between trips to the sink. **Performance:** Midea lists 218 CFM of airflow on Turbo and rates the unit for up to 4,500 square feet, with a tank of about 4.35 gallons. It's rated at 50 pints a day under the DOE 2019 test, and you can also attach a hose for continuous drainage. Midea also posts strong predicted-reliability marks in Consumer Reports' brand surveys. It's our top pick in the [best dehumidifier](https://www.enthusiastreview.com/best/best-dehumidifier/) roundup too. | Spec | Value | | --- | --- | | Capacity | 50 pints/day (DOE 2019) | | Airflow | 218 CFM on Turbo (manufacturer) | | Coverage | Up to 4,500 sq ft (manufacturer) | | Drainage | Large base tank or hose | | Smart control | Wi-Fi app | ## 2. Honeywell 50-Pint Dehumidifier with Pump (TP70PWKNR) — Best for extra-large spaces [Check price on Amazon](https://www.amazon.com/s?k=Honeywell%20TP70PWKNR&tag=sktiger-20) **Pros** - Rated for up to 4,000 square feet - Built-in pump drains up to 15 feet away - ENERGY STAR certified - Uses a lower-impact refrigerant than its predecessor **Cons** - Costs more than the Midea Cube - Taller, more traditional box shape **Why we picked it:** When the room is truly oversized — a finished attic, a vaulted great room, a converted loft — and nowhere near a drain, this Honeywell's coverage rating and pump make sure it isn't undersized or tethered to a bucket. **Performance:** It's sold as a 70-pint unit under the old test standard, which equals a 50-pint rating under the current 2019 DOE procedure. Honeywell rates it for up to 4,000 square feet, and the pump can push water vertically or horizontally up to about 15 feet. The TP70PWKNR is the newer eco-refrigerant version of the long-running TP70PWKN, and both are ENERGY STAR certified. See the rest of the lineup in our [Honeywell dehumidifier guide](https://www.enthusiastreview.com/best/best-honeywell-dehumidifier/). | Spec | Value | | --- | --- | | Capacity | 50 pints/day (DOE 2019); 70 under old standard | | Coverage | Up to 4,000 sq ft (manufacturer) | | Drainage | Built-in pump, up to about 15 ft | | Efficiency | ENERGY STAR | | Best for | Attics, lofts, vaulted rooms | ## 3. hOmeLabs 50-Pint Wi-Fi Dehumidifier with Pump (HME1003) — Best value with a pump [Check price on Amazon](https://www.amazon.com/s?k=hOmeLabs%20HME1003&tag=sktiger-20) **Pros** - Built-in pump for continuous draining - Wi-Fi app shows humidity from anywhere - Usually less expensive than the Honeywell - Same 50-pint class as the other big picks **Cons** - Louder than the Frigidaire - Needs a sink, window or drain within hose reach **Why we picked it:** If you want pump convenience without paying top dollar, the HME1003 is the value play. It drains continuously through a hose, so it never needs emptying, and the app is handy in a large multi-use room you're not sitting in all day. **Performance:** It's a 50-pint-class compressor dehumidifier with a built-in pump and app control, and it's also our pick for large or wet spaces in the [basement guide](https://www.enthusiastreview.com/best/best-dehumidifier-for-basement/). Owners like setting a humidity target in the app and forgetting about it. Check the pump hose occasionally for kinks — that's the most common reason pump units shut off. | Spec | Value | | --- | --- | | Capacity | 50-pint class | | Drainage | Built-in pump | | Smart control | Wi-Fi app | | Type | Compressor | | Best for | Large rooms far from a drain | ## 4. Frigidaire 22-Pint Dehumidifier (FFAD2233W1) — Best quiet pick [Check price on Amazon](https://www.amazon.com/s?k=Frigidaire%20FFAD2233W1&tag=sktiger-20) **Pros** - Among the quieter compressor units available - Five-year sealed-system warranty from Frigidaire - Simple controls with a humidistat - Continuous-drain option **Cons** - Far less capacity than the 50-pint picks - Only for moderately damp rooms **Why we picked it:** A great room where the TV and the dehumidifier share the same air is where a loud 50-pint machine becomes the thing everyone complains about. If the space is big but only mildly damp, this smaller Frigidaire trades capacity for a noise level you can actually live with. **Performance:** It's rated at 22 pints a day, so it suits a large room with moderate humidity rather than a very damp one. Independent noise measurements put it in the mid-40s decibels on low from about 10 feet away — roughly library-quiet — which is notably lower than many 50-pint units. For more low-noise options, see our [quiet dehumidifier picks](https://www.enthusiastreview.com/best/best-quiet-dehumidifier/). | Spec | Value | | --- | --- | | Capacity | 22 pints/day | | Type | Compressor | | Noise | Mid-40s dB on low (independent measurement) | | Drainage | Bucket or gravity hose | | Best for | Lived-in, moderately damp rooms | ## Large rooms, by the numbers - **50 pints** — DOE 2019 capacity recommended for a very damp room over about 2,000 sq ft - **218 CFM** — Midea's listed Turbo airflow for the Cube 50 - **4,000 sq ft** — Honeywell's coverage rating for the TP70PWKNR Airflow is the underrated number. Two 50-pint dehumidifiers can cover very different floor areas depending on how much air they move, which is why it's worth checking the CFM figure or coverage rating rather than the pint number alone. ## How we pick large-room dehumidifiers We don't lab-test. We compared capacity under the 2019 DOE test, manufacturer airflow and coverage ratings, tank size and pump options, ENERGY STAR status and warranty terms, and we looked for published, independent noise figures rather than marketing words like "whisper quiet." We also read owner reviews for patterns that matter in a busy living space: noise complaints, buckets that fill too quickly, pumps that fail and humidity sensors that read far off a separate hygrometer. ## What to look for in a large-space dehumidifier - **High capacity, rated the current way:** Look for a 50-pint rating under the 2019 DOE test. Older "70-pint" labels describe the same class of machine. Our [size guide](https://www.enthusiastreview.com/guides/dehumidifier-size-guide/) has the full chart. - **Airflow or coverage figure:** A higher CFM rating moves moisture from across an open floor plan to the machine faster. - **Tank size or a pump:** A big room fills a small bucket quickly. A large tank buys time; a pump eliminates emptying altogether. See our [pump picks](https://www.enthusiastreview.com/best/best-dehumidifier-with-pump/). - **A real noise number:** If people sit in the room, look for a published decibel figure rather than a "quiet" label. - **Central placement:** One unit can dry a connected open space if it sits centrally with clear airflow. Our [placement guide](https://www.enthusiastreview.com/guides/where-to-place-a-dehumidifier/) explains how. ## How big a dehumidifier do you need for a large room? | Room condition | About 1,000–1,500 sq ft | About 2,000+ sq ft | | --- | --- | --- | | Moderately damp (musty in humid weather) | 35 pints | 50 pints | | Very damp (wet spots, condensation) | 50 pints | 50 pints, or two units | | Wet (standing water, active leaks) | 50 pints with a pump | Fix the source; consider a whole-house system | *Capacities under the 2019 DOE test. Use as a starting point, not a rule.* ### Can one high-capacity dehumidifier dry a whole open floor plan? Yes, if the area is genuinely connected. Air moves freely across an open kitchen, dining and living space, so one well-placed unit can serve it. It won't reach separate bedrooms behind closed doors down the hall. If you need to dry the whole house, a ducted [whole-house dehumidifier](https://www.enthusiastreview.com/best/best-whole-house-dehumidifier/) is the better tool. ## Living with a large dehumidifier - **Set it to 45–50%.** That's comfortable for people and furniture, and it keeps the compressor from running constantly. - **Use the auto or humidistat mode**, not continuous. Continuous mode in a big room wastes power and can over-dry. - **Run it hardest when the house is empty** — during the workday, for example — and let it cycle down in the evening when you want quiet. - **Clean the filter every two to three weeks** in heavy use. A clogged filter cuts airflow, which matters most in a large space. > **What about Hisense?:** Hisense also sells 50-pint models aimed at large rooms, some with built-in pumps. They're worth comparing on price and warranty; see our [Hisense dehumidifier guide](https://www.enthusiastreview.com/best/best-hisense-dehumidifier/) for current models. ## The bottom line The **Midea Cube 50-Pint** is the best large dehumidifier for most big rooms: strong airflow and a tank you won't be emptying constantly. Step up to the **Honeywell TP70PWKNR** for an oversized space far from a drain, choose the **hOmeLabs HME1003** for pump convenience at a lower price, and pick the **Frigidaire FFAD2233W1** when the room is a living space that's only moderately damp and quiet matters most. ## Frequently asked questions ### What is the best dehumidifier for a large room? The Midea Cube 50-Pint (MAD50S1QWT). Midea rates it for up to 4,500 square feet with 218 CFM of Turbo airflow, and its large base tank means fewer trips to the sink. For an oversized space far from a drain, the Honeywell TP70PWKNR adds a built-in pump. ### What size dehumidifier do I need for a large room? Under the 2019 DOE standard, a moderately damp room over about 1,000 square feet needs around 35 pints, while a very damp room or one over 2,000 square feet needs 50 pints or more. ### What is a high-capacity dehumidifier? Generally, a portable unit rated at 50 pints a day under the current DOE test — the same machines once sold as 70-pint units. Beyond that, you're into commercial or ducted whole-house systems. ### Should a large-room dehumidifier have a pump? It's worth it if the room is far from a sink or drain, or if you want the unit to run for days unattended. In a room you pass through daily, a large tank like the Midea Cube's is often enough. ### Are large dehumidifiers loud? They're usually louder than small units because they move more air. If the room is a living space, look for a published decibel figure, run the unit on auto rather than continuous, and consider a smaller, quieter model like the Frigidaire FFAD2233W1 if the room is only mildly damp. ### Does Hisense make a large room dehumidifier? Yes, Hisense sells 50-pint models aimed at large rooms, including versions with a built-in pump. Compare their coverage ratings, warranty and noise figures with the picks above before buying. ## Related guides - [The Best 50-Pint Dehumidifiers](https://www.enthusiastreview.com/best/best-50-pint-dehumidifier/) - [The Best 70-Pint Dehumidifiers (That Really Are 70 Pints)](https://www.enthusiastreview.com/best/best-70-pint-dehumidifier/) - [The Best Whole-House Dehumidifiers](https://www.enthusiastreview.com/best/best-whole-house-dehumidifier/) - [The Quietest Dehumidifiers for Bedrooms, Offices and Nurseries](https://www.enthusiastreview.com/best/best-quiet-dehumidifier/) - [The Best Dehumidifiers with a Built-In Pump](https://www.enthusiastreview.com/best/best-dehumidifier-with-pump/) - [What Size Dehumidifier Do You Need?](https://www.enthusiastreview.com/guides/dehumidifier-size-guide/) --- *Enthusiast Review researches products against DOE ratings, ENERGY STAR data, manuals, CPSC recalls and owner reviews; it does not run a test lab.
