Midea Cube MAD35S1QWT 35-Pint Smart Dehumidifier

Moisture Removal Performance

Consumer Reports gave the MAD35S1QWT the highest score in their three size categories for moisture removal — a clean win over every other 35-pint unit in their 2026 lab tests. Quietest.org's real-world testing showed the unit pulled roughly 21 pints per day in a basement at 70% RH and 75°F, climbing to 28 pints per day under hot-and-humid conditions of 80% RH and 85°F. Those numbers are realistic for a mid-capacity 35-pint compressor and put it in the same performance bracket as much louder competitors.

Dehumidifier Buyers Guide called it the best 35-pint dehumidifier currently on the market, citing the same combination of Energy Star efficiency, low noise, and large tank that earned the 50-pint sibling top honors. The unit hits target humidity quickly in rooms up to 1,500 square feet and holds setpoint with minimal cycling — which is also what keeps the lifetime energy bill manageable.

Coverage and Room Size Fit

Midea markets the unit for spaces up to 3,500 square feet, but quietest.org explicitly flagged that as inflated — real-world effective coverage is closer to 1,500 square feet for keeping target humidity, with the larger number applying only to occasional drying of a damp space. Buyers should size by realistic coverage: this unit is ideal for 800 to 1,500 square feet of living area, a finished basement under 1,800 square feet, or a single floor of a smaller home.

For anyone with a 3,000-plus square foot conditioned space, the 50-pint MAD50S1QWT or Honeywell TP50AWKN is the right step up. For a single bedroom or sub-500 square foot office, the 20-pint MAD20S1QWT in this lineup is the better fit on both noise and size. The 35-pint sits squarely in the middle: the right answer for a typical condo, smaller starter home, or finished basement family room.

Setup and Drain Options

The MAD35S1QWT comes with a gravity-drain hose, but unlike the 50-pint sibling there is no built-in pump on this SKU. For installations where the drain destination is below the unit, that is fine — set up the hose and forget about it. For setups where the destination is above (utility sink halfway up a basement wall), the 35-pint Cube cannot service that geometry without an aftermarket pump kit.

When run on the bucket, the 3.2-gallon (25.6-pint) tank is the second-largest in this category — only the 50-pint Cube's 34-pint tank beats it. Quietest.org noted the tank emptying process is awkward because the bucket pours through an opening that doesn't quite line up with most kitchen sinks. The lift-and-twist storage mode is convenient for offseason garage stowage between summers.

Noise and Bedroom Friendliness

Quietest.org measured 50.4 dB on low and 52.2 dB on high — the quietest 35-pint unit they have tested, and meaningfully quieter than the 50-pint Cube's 65 dB low. Consumer Reports described the unit as "whisper-quiet" in their lab evaluation, which they reserve for the rare dehumidifier that disappears into background noise during normal living-space operation. It is genuinely livable in a living room with the TV on at moderate volume.

For bedroom placement, quietest.org cautions that even 50 dB is audible to light sleepers — "it's not silent, but it's manageable." Deep sleepers will tune it out, but anyone sensitive to fan noise should place it in an adjacent room. The MAD20S1QWT 20-pint sibling tests at similar low-dB readings with smaller capacity; the LG PuriCare line is the only consumer dehumidifier that consistently tests below 50 dB on low, but trades that for higher sticker price and shorter coverage.

Energy Use and Long-Term Cost

The MAD35S1QWT is Energy Star Most Efficient certified and draws roughly 310 watts at 50% RH — substantially less than the 50-pint Cube's 512 W draw, which is the natural result of a smaller compressor. Over a summer running 10 hours per day at U.S. average residential rates, the energy cost lands in the $50 to $70 range — meaningful for budget-conscious buyers and a strong argument for sizing this rather than the 50-pint sibling when the room layout permits.

Sticker price typically lands $50 to $80 below the 50-pint MAD50S1QWT, putting it close to the hOmeLabs HME020031N's territory while offering meaningfully better noise and warranty experience. Like all Midea Cube SKUs, the one-year warranty is the weak point — Honeywell offers five years on the sealed system on its 50-pint, which is worth real money over a decade of ownership.

Smart Features

The MAD35S1QWT shares the MideaAir SmartHome app with its 50-pint and 20-pint siblings. Wi-Fi, Alexa, and Google Assistant integration all work the same way — scheduling, target humidity, mode toggles, and a basic dashboard of readings. Quietest.org found the smart features functional but unspectacular: "useful for remote monitoring, not transformative." Voice commands respond within a second or two and the unit retains state through power loss.

The same app stagnation that affects the 50-pint Cube affects this SKU — MideaAir has not received feature updates in over a year as of mid-2026, and the basic UI feels older than 2026 expectations. Wi-Fi pairing requires a 2.4 GHz network, which can be a pain on modern mesh setups where the dehumidifier needs to be specifically connected to the legacy band. Once paired, the connection has been reliable in user reports.

What Reviewers Loved

Consumer Reports' verdict drove much of the unit's reputation: highest score of any 35-pint unit in their lab in 2026, with top marks for energy efficiency and convenience. Dehumidifier Buyers Guide reinforced the verdict with the simple statement that this is "the best 35 pint dehumidifier currently on the market." Quietest.org's noise measurements explained why — the same compressor and fan architecture that makes the Cube line top performers, scaled down to a more livable 35-pint footprint. Home Depot customer reviews consistently echo the same praise: quiet, energy-efficient, and the large tank means less attention than 22-pint units demand.

Where It Falls Short

The absence of a built-in pump on this SKU is the biggest functional limitation. Buyers who specifically need to lift water above the unit have to step up to the 50-pint MAD50S1QWT or accept an aftermarket pump kit. The 3,500 sq ft marketing claim is also inflated — quietest.org's testing pegged realistic coverage at 1,500 sq ft for holding target humidity, which is closer to half the advertised area.

The tank emptying experience is awkward — the bucket has to be lifted and rotated to pour cleanly into a sink, and full-tank weight at 26 pints is meaningful. The app's lack of recent updates raises long-term concerns about smart-feature support over the unit's expected eight-to-ten-year service life. And the one-year warranty trails the five-year coverage on Honeywell's competitors.

Who It's Best For

The MAD35S1QWT is the right pick for someone with 800 to 1,500 square feet of living area, a smaller finished basement, or a starter home with a single-floor footprint. It is particularly well-suited to placement in a living room or open kitchen where quiet operation matters and the gravity drain hose can run to a nearby drain. Consumer Reports' verdict makes it the safe default for mid-capacity buyers who are not sure which SKU to pick.

It is not the right pick for users who need pump drainage (step up to the 50-pint MAD50S1QWT) or for very small spaces under 600 sq ft where the 20-pint MAD20S1QWT fits better. Buyers who want maximum warranty coverage should consider the Honeywell TP50AWKN's five-year sealed-system policy instead. And anyone planning to drop this in a 3,000-plus square foot open-concept layout should size up — the 35-pint cannot hold setpoint in that volume of conditioned air.
