Best Dehumidifiers for Basement in 2026 (70-Pint Units Tested)

The best basement dehumidifiers in 2026 compared by capacity, drainage, noise, and energy efficiency. Expert picks for finished basements, crawl spaces, and large unfinished areas.

HVAC Base TeamUpdated February 5, 202613 min read

The best overall basement dehumidifier in 2026 is the LG PuriCare UD701KOG3 (70-pint) — it combines the highest energy efficiency in its class (IEF 3.20), a built-in pump for basements without floor drains, Wi-Fi connectivity, and a remarkably quiet 44 dB noise level. For budget-conscious buyers, the Midea MAD50S1QWT (50-pint) delivers strong performance at $100 less.

Most basements need a 50- or 70-pint dehumidifier. The right choice depends on your basement's size, moisture severity, and whether you have a floor drain. Below, we compare the top models across every factor that matters.

Quick Picks: Best Basement Dehumidifiers 2026

What Makes a Great Basement Dehumidifier

Basements have unique challenges that separate good dehumidifiers from great ones for this application:

High moisture loads: Basements are below grade, surrounded by damp soil. Moisture wicks through concrete walls and slabs. Even "dry" basements can have 55–65% RH in summer without a dehumidifier.

Cool temperatures: Basements are typically 5–15°F cooler than the main floor. In unfinished basements, summer temps can hover around 60–68°F — right at the threshold where compressor dehumidifiers start losing efficiency and risking frost.

Drainage challenges: Many basements lack a floor drain, making continuous drainage difficult. A built-in pump solves this by pushing water upward through a hose to a utility sink, window, or upper-level drain.

Out of sight, out of mind: Basement dehumidifiers often run unsupervised. Smart features (Wi-Fi alerts, humidity monitoring, full-bucket notifications) prevent problems you wouldn't notice until they become serious.

Important

The single most important feature for a basement dehumidifier is reliable drainage. A bucket that fills up every 8 hours will overflow if you forget to empty it — and the unit shuts off, allowing humidity to spike back above 60%. Set up continuous gravity drainage or buy a pump model.

Detailed Reviews

1. LG PuriCare UD701KOG3 — Best Overall

The LG PuriCare 70-pint is the highest-performing basement dehumidifier available in 2026. Its IEF of 3.20 L/kWh is the best in the 70-pint class, meaning it removes more moisture per dollar of electricity than any competitor.

Key specs: 70 pt/day capacity, 680W, IEF 3.20, 44 dB, built-in pump (pumps up to 16 ft vertically), 1.6-gallon bucket, Wi-Fi with LG ThinQ app, auto-restart after power outage.

Why it's great for basements: The built-in pump eliminates drainage headaches. The 44 dB noise level is the quietest in the 70-pint class — important if your basement is a finished living space. Wi-Fi connectivity lets you monitor humidity from upstairs and get alerts if the unit encounters a problem.

Limitations: Premium price ($330–$380). The LG ThinQ app requires a 2.4 GHz Wi-Fi network (not compatible with 5 GHz-only networks). Heavier than average at 48 lbs.

Best for: Medium to large basements (1,000–3,000 sq ft) where you want top efficiency, quiet operation, and set-it-and-forget-it convenience.

2. Midea MAD50S1QWT — Best Value 50-Pint

The Midea 50-pint hits the sweet spot of price, performance, and efficiency. Its IEF of 2.75 is among the best in the 50-pint class, and the price typically stays under $270.

Key specs: 50 pt/day capacity, 500W, IEF 2.75, 46 dB, gravity drain hose included, 1.6-gallon bucket, digital humidistat, auto-defrost.

Why it's great for basements: Excellent efficiency keeps running costs low ($16–$18/month). The included gravity drain hose makes continuous drainage simple if you have a floor drain. Auto-defrost handles the cool-basement temperature challenge well.

Limitations: No built-in pump — you'll need an external condensate pump ($30–$50) if there's no floor drain below the unit. No Wi-Fi connectivity. The bucket is slightly difficult to remove without spilling.

Best for: Small to medium basements (500–1,500 sq ft) with a floor drain or sump pit nearby. Budget-conscious buyers who want strong efficiency.

3. Midea Cube MAD50PS1QGR — Best Compact Design with Pump

The Midea Cube stands out with its unique vertical design that takes up just 1 sq ft of floor space — half the footprint of traditional dehumidifiers. It includes a built-in pump.

Key specs: 50 pt/day, 510W, IEF 2.65, 44 dB, built-in pump, Wi-Fi with Midea Air app, unique vertical form factor.

Why it's great for basements: The compact footprint is valuable in finished basements where space matters. The built-in pump handles basements without floor drains. Smart features let you monitor remotely.

Limitations: The vertical bucket design can leak slightly if the unit is bumped or moved while the bucket is partially full. Slightly lower IEF than the standard Midea 50-pint.

Best for: Finished basements with limited floor space, especially where the dehumidifier will be visible.

4. Tosot 70-Pint — Best Budget 70-Pint

The Tosot delivers 70-pint capacity and a built-in pump at a price point typically $50–$70 below the LG. It's a strong choice if you need high capacity without the premium price.

Key specs: 70 pt/day, 720W, IEF 2.90, 48 dB, built-in pump, gravity drain, 1.68-gallon bucket, auto-defrost, auto-restart.

Why it's great for basements: Excellent capacity-to-price ratio. The built-in pump handles drainage without additions. Auto-restart ensures the unit comes back on after a power outage — critical for unattended basement operation.

Limitations: Louder than the LG (48 dB vs 44 dB). Higher wattage (720W vs 680W). No Wi-Fi capability.

Best for: Large basements (1,500–3,000 sq ft) where maximum moisture removal matters more than quiet operation or smart features.

5. Santa Fe Compact70 — Best for Crawl Spaces

The Santa Fe Compact70 is purpose-built for tight, challenging spaces. It operates at temperatures as low as 49°F without frosting issues and features a low-profile design (12.5" tall) that fits in crawl spaces with limited clearance.

Key specs: 70 pt/day, 700W, IEF 2.50, 52 dB, low-profile design (12.5"H), operates down to 49°F, MERV-8 filter, commercial-grade components, 5-year warranty.

Why it's great for basements/crawl spaces: Specifically engineered for the challenging conditions where standard dehumidifiers fail. The low-temperature rating means reliable operation in unheated spaces year-round. MERV-8 filtration captures finer particles than the basic mesh filters on consumer models. The 5-year warranty reflects commercial-grade construction.

Limitations: Significantly more expensive ($1,100–$1,350) than consumer-grade units. Louder at 52 dB. No smart features. Designed for performance, not aesthetics.

Best for: Crawl spaces, unheated basements below 65°F, and serious moisture problems where reliability is paramount.

How to Choose: Decision Guide

Choose the LG 70-pint if: You have a medium-to-large basement, want the lowest running costs, need a built-in pump, and value smart home integration. You're willing to pay a premium for the best available performance.

Choose the Midea 50-pint if: Your basement is under 1,500 sq ft, you have a floor drain for gravity drainage, and you want the best efficiency-to-price ratio. You don't need Wi-Fi or a pump.

Choose the Midea Cube if: Floor space is limited, your basement is a finished living area where aesthetics matter, and you need a pump but don't need 70-pint capacity.

Choose the Tosot 70-pint if: You need maximum moisture removal at a reasonable price, have a large or very damp basement, and noise isn't a primary concern.

Choose the Santa Fe if: You're dehumidifying a crawl space, your basement is unheated and drops below 60°F regularly, or you've had consumer-grade dehumidifiers fail on you and want commercial-grade reliability.

Key Takeaway
  • For most basements, a 50-pint ENERGY STAR unit ($230–$320) is sufficient up to 1,500 sq ft
  • Large or very damp basements (1,500+ sq ft) need a 70-pint unit ($280–$380)
  • A built-in pump is essential if you don't have a floor drain — it's worth the $30–$80 price premium
  • Crawl spaces and unheated basements below 65°F need specialized low-temperature units like the Santa Fe line
  • Set up continuous drainage from day one — don't rely on manually emptying the bucket
  • Wi-Fi connectivity is a genuine value-add for basement units that run unsupervised for weeks
