Dehumidifier Cost Per Pint: Why the 70-Pint Is the Expensive One
Dehumidifiers are sold by sticker price and bought by capacity, and the two run in opposite directions. Across the units we track, real cost runs from about $3.17 per pint/day (145-pint crawl space) to about $5.71 (70-pint), a 1.8x spread, with a median near $4.44. The pattern is consistent: every step up in capacity lowers the cost per pint, so a $459 145-pint machine is cheaper per pint removed than a $400 70-pint one — while also finishing the job sooner and cycling less. Buy the largest capacity your space and drainage can take, and treat a built-in pump as a $59 line item, not a tier.

What dehumidifiers costs per pint/day
Live price terciles across the 23 dehumidifiers products we track, by real cost per pint/day.
| Tier | Cost / pint/day | Example pick |
|---|---|---|
| Budget | $3.17–$4.00 | Argendon Sandidry Elite 80C 170-Pint SLGR… ($3.76/pint/day) |
| Mid-range | $4.10–$4.82 | Argendon Wholesale Pack – XStorm Pro ($4.44/pint/day) |
| Premium | $4.83–$5.71 | 120-Pint Commercial Dehumidifier for Large… ($4.99/pint/day) |
The unit that matters is a pint per day, not a box
A dehumidifier's price tells you almost nothing on its own. Two machines on the same shelf can differ by $60 and by a factor of two in how much water they remove. The comparable number is cost per pint per day: the price divided by the capacity rating printed on every spec sheet.
Run that division across the units we track and the ranking inverts. The cheapest machine by sticker price is the most expensive machine by capacity.
| Unit | Price | Capacity | Cost / pint per day |
|---|---|---|---|
| 145-Pint Crawl Space & Under House | $459.00 | 145 pint | $3.17 |
| 145-Pint SLGR Commercial, with pump | $479.99 | 145 pint | $3.31 |
| 170-Pint Sandidry Elite 80C | $639.99 | 170 pint | $3.76 |
| 180-Pint Industrial, with pump | $719.10 | 180 pint | $4.00 |
| 120-Pint Crawl Space, with pump | $598.00 | 120 pint | $4.98 |
| 70-Pint Crawlspace & Basement | $337.25 | 70 pint | $4.82 |
| 70-Pint Heavy-Duty Crawl Space | $399.99 | 70 pint | $5.71 |
The spread between the ends is 1.8x. Someone comparing the $337 70-pint against the $459 145-pint sees a $122 saving; per pint of water actually removed, they are paying 52% more.
Capacity is the cheapest thing in the box
The reason is structural. A dehumidifier is a compressor, a coil, a fan, a housing, controls, a drain fitting and a carton. Only the first two scale with capacity — the rest cost roughly the same whether the machine is rated 70 pints or 180. Doubling the rating therefore costs far less than double, and the fixed share gets spread over more work.
That also shows up in the middle of the table: the 120-pint units sit at $4.98–$4.99 per pint/day, worse than every 145-pint unit and barely better than a 70-pint. Capacity tiers are not evenly priced, so the arithmetic is worth doing per model rather than assuming "bigger is proportionally more".
What the pump costs, exactly
Two listings of the same 70-pint crawl space unit differ only by the pump: $337.25 without, $396.19 with. That is $58.94, or 17% — a line item, not a product tier.
Buy it when the unit sits below the drain and condensate has to be lifted, which is the normal case in a crawl space with no floor drain. Skip it when gravity already carries the water out; a pump you do not need is one more part that can fail in a space you rarely visit.
"Wholesale Pack" is a channel label, not a discount
Four listings carry a "Wholesale Pack" prefix. Their per-pint cost lands at $4.44 (180-pint), $4.71 and $4.83 (170- and 145-pint) — in every case at or above the plain listing of the same capacity, and well above the $4.00 the cheapest 180-pint unit reaches. Nothing about the label lowers what a pint costs.
The short version
Pick the capacity your space needs, then compare candidates on price ÷ pints, not on price. In this catalog that consistently favours 145-pint and larger machines, which sit between $3.17 and $4.95 per pint/day, over the 70-pint tier at $4.82–$5.71. Add a pump only if the drain is above the unit.

Frequently asked questions
What does "70-pint" actually mean on a dehumidifier?
It is the water the unit can pull from the air in 24 hours under a standard test condition, so it is a rate, not a tank size. That is why it works as a pricing unit: two machines rated 70 and 145 pints do the same job at different speeds, and dividing price by that rating tells you what you pay for the work rather than for the cabinet.
Is a bigger dehumidifier always cheaper per pint?
In the range we track, yes, and by a wide margin: 145-pint units land between $3.17 and $4.95 per pint/day while 70-pint units sit at $4.82 to $5.71. Capacity is mostly compressor and coil, and those scale better than the shared costs — housing, controls, pump, packaging — that every unit carries regardless of size.
Should I pay extra for a built-in pump?
It is a small, fixed premium rather than a different class of machine. The same 70-pint crawl space unit is $337.25 without a pump and $396.19 with one — about $59, or 17%. A pump matters when there is no floor drain below the unit and the condensate has to be lifted; if gravity drainage already works, that $59 buys nothing.
Do the "Wholesale Pack" listings save money?
Not on a per-pint basis. Three 180-pint wholesale listings we track price at $799.11, the same $4.44 per pint/day as the ordinary 180-pint listings at the same price — and the cheapest 180-pint unit is $719.10, or $4.00 per pint/day. The label describes the channel, not a discount.
How many pints do I need for a crawl space?
Sizing depends on the volume, how wet it is and whether it is encapsulated, so treat capacity as a spec to match, not a number to maximise blindly. The cost-per-pint reading matters once you have a target range: within that range, the larger rating is nearly always the cheaper way to buy the same extraction.
