Quick Answer
Choose the Midea 50-Pint with Pump for most large or persistently damp basements, especially when the drain is higher than the machine. Choose the Midea Cube 50-Pint when you have a floor drain and want a much larger bucket. The Midea Cube 20-Pint suits a smaller, moderately damp finished basement, and the AlorAir Sentinel HD55S is the pick for a sealed crawl space or low-clearance permanent installation with gravity drainage.
Do not buy a dehumidifier to disguise an active leak — repair the water source first.
Quick Comparison

Advertised square-foot numbers are not directly comparable across brands and should not be the main buying criterion. Basement temperature, starting humidity, air movement, open doors, laundry and water entry can change the real moisture load dramatically.
First: Measure the Basement and Identify the Water Source
Buy a basic hygrometer before buying a dehumidifier — see our ideal basement humidity guide. Health Canada recommends keeping indoor relative humidity between 30% and 50% and specifically recommends running a dehumidifier when RH is above 50%. Before shopping, look for water stains or efflorescence, plumbing leaks, window-well leakage, downspouts discharging near the foundation, poor grading, a struggling sump pump, and stored belongings against damp walls. A dehumidifier handles water vapour already in the air; it cannot seal a crack or remove standing water.
1. Midea 50-Pint Dehumidifier with Pump — Best Overall
The Midea 50-Pint with Pump combines 50-pint capacity with all three practical water-removal options: a bucket, continuous gravity drainage and an internal pump. The pump is the deciding feature — if the nearest sink, window or drain is above the dehumidifier, gravity cannot do the job. Midea's Canadian family lists adjustable humidity from 35% to 85%, auto restart, automatic defrost and a 24-hour continuous cycle. Midea advertises coverage up to 4,500 sq. ft.; treat that as a marketing ceiling rather than a sizing promise.
Why it stands out: built-in pump plus gravity drainage; automatic defrost protects the coil in a cool basement; auto restart after a power interruption.
Reasons to skip it: a pump adds a moving part; Canadian limited warranty is one year; the pump hose must be routed exactly as specified.
Best for: a medium or large basement regularly above 55% RH where the only practical drain is above the unit. Check price on Amazon.ca
2. Midea Cube 50-Pint — Best Large-Bucket Choice
The Midea Cube 50-Pint is the better choice with a floor drain or when you plan to use the bucket. Its lift-and-twist design holds up to three times as much water as a conventional model, and the upper compressor section nests into the bucket for storage. It supports gravity drainage and smart controls, is ENERGY STAR certified and lists automatic defrost, auto shutoff and a washable filter.
Why it stands out: unusually large bucket reduces emptying frequency; nesting design saves storage space; ENERGY STAR certified.
Reasons to skip it: no built-in pump on this model; a full bucket is heavy and awkward on stairs; one-year warranty.
Best for: a large basement with a floor drain, or an owner who values long bucket intervals. Check price on Amazon.ca
3. Amazon Basics 50-Pint with Pump — Promising Value Pick
Fifty-pint capacity, ENERGY STAR certification, a pump, auto defrost, auto restart, timer and overflow protection at a potentially lower price. The Canadian ASIN had almost no review history at the time of research, so this is a conditional pick rather than a blanket recommendation — if the price difference from the Midea pump model is small, buy the model with more ownership history; if materially cheaper, confirm the return window and written warranty first.
Best for: a price-sensitive buyer comfortable choosing a newer listing after checking return and warranty terms. Check price on Amazon.ca
4. Midea Cube 20-Pint — Best for a Smaller, Moderately Damp Basement
Retains the Cube's large-reservoir design, gravity-drain option, app controls, automatic defrost and ENERGY STAR certification in a lower-capacity unit: a 12-litre bucket and 45 dBA manufacturer noise rating, with no built-in pump. The key word is moderately — if the basement starts around 70% RH or smells persistently musty, step up to a 35- or 50-pint model.
Best for: a smaller finished basement that stays in the low-to-mid 50% range. Check price on Amazon.ca
5. AlorAir Sentinel HD55S — Best Crawl-Space or Permanent-Drain Upgrade
Not a conventional bucket-on-wheels appliance — a compact, metal-cased dehumidifier for a crawl space, tight basement or fixed installation with a permanent gravity drain. Rated 55 pints/day under AHAM conditions and 120 pints at saturation (the AHAM figure is the useful comparison number). Coverage up to 1,300 sq. ft., automatic defrost, cETL certification, ENERGY STAR status and a minimum operating temperature near 1°C. No bucket, no pump — requires a continuously downhill drain hose.
Best for: a sealed crawl space or low-clearance basement with a permanent gravity drain. Check price on Amazon.ca See our full crawl-space dehumidifiers guide for more picks in this category.
What Size Dehumidifier Does a Canadian Basement Need?
| Basement Condition | Typical Signs | Capacity Starting Point (<2,000 sq ft) |
|---|---|---|
| Slightly to moderately damp | Intermittent musty odour; ~50–75% RH | 20–30 pints/day |
| Very damp | Consistent odour, damp spots; ~75–90% RH | 25–40 pints/day |
| Wet | Sweating walls or seepage; ~90–100% RH | 30–50 pints/day |
Do not compare an older "70-pint" product title directly with a newer 50-pint rating — federal test conditions changed, so many machines formerly marketed around 70 pints became 50-pint products without a physical downgrade. See our 35-pint vs 50-pint sizing guide for a detailed like-for-like comparison.
Built-In Pump vs Gravity Drain vs Bucket
A gravity hose has no pump motor to wear out and is best when a floor drain is nearby. A built-in pump is worth paying for when water must travel up to a laundry sink, standpipe or window. A bucket makes placement easy but stops the machine when full. Read our full pump vs gravity drain comparison before choosing.
Will a Dehumidifier Work in a Cold Canadian Basement?
Most portable dehumidifiers use a refrigerant compressor; as temperature drops, moisture can freeze on the coil and extraction performance falls. Automatic defrost pauses to clear the ice but does not make every unit suitable for an unheated space in mid-winter. Common portable models are designed for spaces around 5°C or warmer; the AlorAir reviewed here publishes a lower minimum near 1°C.
Recall and Fire-Safety Checklist
- Photograph the complete model, serial number and date-code label.
- Search Health Canada's recalls database for the exact model number.
- Inspect the cord, plug, drain hose and cabinet for heat damage or cracking.
- Plug it into a grounded outlet specified by the manual; avoid extension cords and overloaded power bars.
- Keep air inlets and outlets clear and clean the filter on schedule.
- Stop using the unit if the plug or outlet becomes hot, it smells burnt, or it repeatedly trips a breaker.
Frequently Asked Questions
What humidity should a basement be in Canada?
Health Canada recommends 30%–50% RH. In a basement, 45–50% is a practical starting point.
Is a 50-pint dehumidifier too big for a 1,000-square-foot basement?
Usually not. A humidistat-controlled 50-pint model can pull humidity down faster and then cycle off.
Do I need a pump if I have a floor drain?
No. A correctly sloped gravity hose is simpler and generally preferable when the drain is below the outlet.
Can a dehumidifier drain into a sump pit?
Often, but confirm local practice and the sump setup. The hose must not obstruct the pump, float or cover.
Will a dehumidifier remove mould?
No. Lower humidity can make new growth less likely, but it does not clean existing mould or fix its water source.
Final Verdict
For most damp Canadian basements, buy the Midea 50-Pint with Pump if the drain is above the unit, or the Midea Cube 50-Pint if you have a floor drain. The Midea Cube 20-Pint suits a smaller, moderately damp finished basement. The Amazon Basics 50-Pint with Pump is interesting when meaningfully cheaper, and the AlorAir Sentinel HD55S is a different class of purchase for a fixed crawl-space installation. Whichever machine you choose, measure the humidity, repair water entry, create a reliable drain path and check the exact model number for recalls.
