The Setup: Why These Two Brands End Up on the Same List
I review incoming product for a mid-sized HVAC and appliance distributor. Roughly 2,000 units a year cross my desk. When a customer asks for a dehumidifier or a heat pump, Midea and Mr. Heater are almost always the two names that come up. But for very different reasons.
People think these brands compete directly. Actually, they rarely overlap in the same job. Midea builds inverter-driven heat pumps and multi-functional dehumidifiers. Mr. Heater builds portable propane-based heating. The confusion comes from the Midea saddle mount heat pump—a window unit no one's quite sure how to categorize—and the Mr. Heater patio heater, which isn't really comparable. But customers lump them together because both show up in search results for "home heating."
So here's what I look at when comparing them: build consistency, real-world performance (not spec sheet numbers), and total cost over a season of use. I've rejected batches from both. I've also been surprised by both.
Let me walk through the dimensions that actually matter.
Build Consistency: Midea's Quality Gap Is Smaller Than You'd Expect
Midea Cube Dehumidifier 50 Pint
I've seen a lot of dehumidifiers. The Midea Cube 50 Pint is the first one I genuinely didn't mind unboxing. The plastic feels dense, the seams are tight, and the handle mechanism on the Cube model (the one with the stackable tank) doesn't wobble. That sounds like a low bar, but trust me—it isn't.
What surprised me: the drain hose connection. On the first batch we received in Q1 2024, about 7% had a loose thread fit on the hose port. Normal tolerance is maybe 2-3%. We flagged it. They sent a revised connector within two weeks. That's fast.
What most people don't realize is that Midea uses a single production line for their Cube series across several markets. The same unit sold in the U.S. is essentially the same unit sold in Canada, parts of Europe, and some Asian markets. That means quality control has to scale. And generally, it does. But when it fails, it fails across thousands of units at once, not just a bad batch here and there.
Mr. Heater Patio Heater
Mr. Heater's build philosophy is different. The patio heaters are simpler—fewer moving parts, no compressor, no drain pump. They're basically a propane tank, a burner head, and a reflector. So build consistency tends to be higher, because there's less to go wrong.
But I've caught something: the reflector alignment is inconsistent across units. On about 1 in 20 units, the reflector is visibly tilted by 2-3 degrees. That affects heat direction. The vendor claimed it was "within industry standard." (Which is true, technically.) But on a 50,000-unit annual order, that's 2,500 units with suboptimal heat distribution. For a patio heater, that matters.
To be fair, the fix is trivial—just bend it back—but the fact that it ships like that tells me their final inspection is either rushed or focused on different criteria than what I care about.
Build Verdict
- Midea: More complex product, but tighter tolerances on most components. Risk: production-scale defects.
- Mr. Heater: Simpler product, fewer failure modes, but inconsistent fit/finish on output-critical parts.
If I were buying purely on build consistency, I'd lean Midea for the Cube. But that's before we talk about performance.
Performance: Spec Sheets Lie, Real Usage Tells the Story
How Does a Dehumidifier Work (and Does Midea's Actually Excel?)
People think a dehumidifier's performance is just about pint capacity. Actually, the real metric is how consistently it maintains a target humidity level across varying temperatures. The Midea Cube 50 Pint uses an inverter compressor. That means it doesn't just cycle on and off—it adjusts its speed to match the load.
What that means in practice: in a 70°F basement with 65% RH, the Midea Cube pulls down to 50% in about 2 hours and then holds it within ±2% without cycling. Most non-inverter units hit a target, then overshoot by 5-8%, then cycle off, then kick back on when humidity climbs again. That cycling wastes electricity and wears the compressor.
Here's something vendors won't tell you: the 50-pint rating is at 65°F and 60% RH. At lower temperatures (which is where most people actually use dehumidifiers—basements in the 50s), that rating drops by about 20-30%. The Midea Cube still outperforms most competitors at lower temps because the inverter compressor can still operate efficiently. But don't expect 50 pints at 55°F. More like 35-38.
Midea Saddle Mount Heat Pump: The Wildcard
The saddle mount heat pump is weird. It sits partially inside and partially outside the window (the bottom part sticks out). It's a through-wall unit but for windows. I've never fully understood why they designed it that way. My best guess is it achieves a lower profile than traditional window units while keeping the compressor outside the living space (for noise).
Performance-wise: heating mode is surprisingly good. At 30°F outdoor temp, it maintained 68°F in a 400-square-foot room. But cooling mode is just average. The saddle design creates some airflow inefficiency on the outdoor side. It works. It just doesn't blow me away.
The assumption is that the saddle mount is an upgrade over standard window heat pumps. The reality is it's a tradeoff: you get a nicer look and better heating, but you pay more and the cooling is slightly worse. People think expensive vendors deliver better quality. Actually, vendors who deliver quality can charge more. The causation runs the other way.
Mr. Heater Patio Heater
Mr. Heater's patio heaters are simple: they burn propane, they radiate infrared heat. Performance is straightforward. What matters is how even the heat distribution is and how long a tank lasts.
At max output (about 46,000 BTU), a 20-lb propane tank lasts roughly 6-7 hours. On low (13,000 BTU), it stretches to about 18 hours. That's pretty standard for this category. But I've noticed something: the reflector shape on Mr. Heater models creates a hot zone directly above the unit about 4 feet wide, with a rapid drop-off. If you're sitting 5 feet away, you feel it. At 8 feet, you feel significantly less. That's not unusual, but it matters if you're setting up for a large patio.
In my first year reviewing these, I made the classic error: assumed a higher BTU rating meant better heating. Actually, reflector design matters more. I learned that lesson when I put a 46,000 BTU unit on a windy night and realized the heat was just going straight up. A 30,000 BTU unit with a proper reflector would have been warmer.
Performance Verdict
- Midea Cube: Best-in-class for holding humidity levels, especially at low temps. But the dehumidifier drops off in cold basements more than the sticker suggests.
- Midea Saddle Mount: Great heating, okay cooling. A compromise product.
- Mr. Heater Patio: Performance is fine. Reflector alignment and wind protection matter more than BTU claims.
Total Cost Over a Season: Where the Premium Pays For Itself
Midea Cube Energy Savings
The inverter compressor saves about 25-35% electricity vs a standard dehumidifier compressor. At 8 hours daily, 6 months of operation, that's about $40-60 in savings at U.S. average electricity rates (roughly $0.14/kWh as of January 2025). The Unit itself costs about $260. A comparable non-inverter 50-pint is around $180. So the payback period is about two seasons.
If you're running a dehumidifier year-round (which many basements need), the payback is even faster. But that's only if you actually need 50-pint capacity. If a 30-pint would work, you're overpaying for capacity you don't use.
Mr. Heater Patio Fuel Costs
Propane isn't cheap. A 20-lb tank refill is about $15-20. If you use the patio heater for 3 hours a night, 3 nights a week during the colder months, that's roughly one tank every two weeks. Over a 4-month season, that's $120-160 in fuel costs alone.
A Midea saddle mount heat pump running on electricity might cost $50-80 over the same period, but you can't take it outside. So they're not really substitutes. But when customers ask me which is cheaper to run, I have to tell them: the heat pump is cheaper per hour, but only works indoors (or in a weather-protected space). The Mr. Heater is for open-air use. They're different tools.
I knew I should factor in tank rental/ownership costs for propane (if you don't own a tank, you're renting). Not everyone thinks about that. It adds $20-40 per year.
Total Cost Verdict
- Midea Cube: Higher upfront, lower operating cost. Payback in 1.5-2 seasons. Good for year-round usage.
- Mr. Heater Patio: Lower upfront, higher fuel cost. What you save on the unit, you spend on propane.
Which One Should You Buy? A Practical Guide
This isn't about which brand is "better." It's about what you need.
For Basement Humidity
Get the Midea Cube if: your basement stays below 65°F in summer (most do), and you want consistent humidity without the compressor cycling on and off all night. The inverter compressor genuinely matters here.
Get something else if: you only need a dehumidifier for a few weeks in peak summer. The premium for the Cube won't pay back.
For Room Heating (Supplemental)
The Midea saddle mount heat pump is an option if you can't use a window unit (HOA, noise concerns, or you just hate seeing a big box in the window). But it's not a replacement for a real mini-split or central heat pump.
For a garage or workshop: skip the saddle mount. Get a Mr. Heater propane unit if you have ventilation. Or a simple infrared electric heater. The saddle mount doesn't work well in spaces with high ceilings or drafty walls.
For Outdoor Heating
Mr. Heater patio heater is the standard. But check the reflector alignment when it arrives. And budget for propane — it's not pocket change.
I should add that there's a middle option I haven't mentioned: the Midea heat pump water heater (if you're thinking about whole-home solutions). That's a different conversation. But it tells you Midea is thinking about heat pump technology more broadly than just window units.
Ultimately, the right choice depends on your specific situation. If you're dealing with a damp basement, the Midea Cube is a smart investment. If you need to heat a patio, the Mr. Heater is the tool for the job. Just know the tradeoffs before you buy.
