Dehumidifiers / Ivation
Ivation 19 Pint Small-Area Desiccant Dehumidifier (IVADDH09)
The right machine for a cold basement, under a pint number its own page contradicts.
Overall score 5.4/10
Pros
- + Works down to 33°F, so it is the correct answer for a 50-55°F basement, garage or crawlspace where a compressor unit frosts
- + No compressor means no start-stop thump through a floor and no defrost dead time
- + Drain hose is actually in the box, which is not true of most compressor units at this price
- + Light and genuinely portable, unlike the 40+ lb compressor units it competes with
Cons
- − Sold as "19 Pint" while Ivation's own page rates it at 13 pints/day at 68°F — a 46% gap in the manufacturer's own published figures
- − $299.99 buys roughly a quarter of the daily water removal of a $242 hOmeLabs 50-pint
- − Regeneration heater makes it the second-most expensive unit here to run per pint, and Ivation publishes no wattage at all
- − Tank capacity is published two ways (0.75 gal by Ivation, 0.5 gal by Best Buy) and neither lasts a day without the hose
- − Ivation-branded compressor dehumidifiers were part of the 2021 New Widetech CPSC recall
Ivation 19 Pint Small-Area Desiccant Dehumidifier (IVADDH09) review: what the specs say
The right machine for a cold basement, under a pint number its own page contradicts. At $299.99, Ivation's 2019 model sits in the middle of the range — the dehumidifiers we compare run from $46.42 to $1,507. It scores 5.4/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Cold-Room Performance at 9.5/10 — what happens in a 50-55°F basement, garage or crawlspace. Compressor coils frost below roughly 65°F and auto-defrost buys back the coil at the cost of runtime; desiccant rotors and hot-gas-defrost units do not care. The single most common mis-buy in the category. The weakest is Capacity-Claim Honesty at 3.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: sold as "19 Pint" while Ivation's own page rates it at 13 pints/day at 68°F — a 46% gap in the manufacturer's own published figures; and $299.99 buys roughly a quarter of the daily water removal of a $242 hOmeLabs 50-pint. Every specification on this page comes from Ivation's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Rated Capacity (and Which Standard) | Sources conflict, and the conflict is the whole story: Ivation's own product page states "13 pints per day at 60% RH, 68°F" while the product is sold everywhere — Best Buy, Walmart, Lowe's, Amazon — as a "19 Pint" dehumidifier. Neither figure is a DOE Appendix X1 (65°F/60% RH) rating |
| ENERGY STAR / DOE Verified Capacity | None. Ivation does not appear in the ENERGY STAR Certified Dehumidifiers database. Desiccant units are not covered by the DOE portable-dehumidifier test procedure, so no third-party-verified capacity exists for any desiccant unit sold in the US pints/day |
| Technology & Refrigerant | Desiccant rotor. Air passes through a moisture-adsorbing wheel which is then regenerated by a heater; the driven-off water is condensed into the tank. No refrigerant, no compressor, no coil |
| Low-Temperature Operation & Defrost | The reason to buy this. Best Buy's spec sheet gives an operating range of 33°F to 104°F (1°C to 40°C). A compressor unit in a 55°F basement spends much of its runtime in defrost; a desiccant rotor does not care. Desiccants also warm the room slightly, which is a feature in a cold crawlspace and a nuisance in July |
| Claimed Coverage | 410 sq ft (Ivation, and every retailer agrees on this one) |
| Tank Capacity & Refill Interval | Sources conflict: Ivation's own page says "0.75 gal (2.8L) tank"; Best Buy's spec sheet says "½-gallon tank". At the manufacturer's own 13 pints/day that is between two and three emptyings a day without a hose |
| Continuous Drainage (Hose, Gravity, Pump Lift) | Continuous gravity drain with the hose included in the box. No pump — the outlet has to sit above the drain, which in a crawlspace usually means a condensate pump bought separately |
| ENERGY STAR Status | Not ENERGY STAR certified and not eligible — the programme's dehumidifier scope does not cover desiccant units |
| Annual Running Cost | Not published. Ivation publishes no wattage for this model and there is no ENERGY STAR annual-energy figure. Desiccant units carry a regeneration heater and typically draw several hundred watts continuously, so expect running cost well above a compressor unit of similar output — this is the price you pay for cold-room capability |
| Noise | No dB figure published. Ivation claims "whisper quiet"/"nearly silent"; there is no compressor to cycle, but there is a continuous fan |
| Warranty (incl. Sealed System) | Not published on Ivation's product page, Best Buy's listing or Walmart's. Ivation's standard consumer warranty is 12 months; confirm at purchase |
| Recall History | Ivation appears on the CPSC's 4 August 2021 New Widetech recall of approximately 2 million dehumidifiers (25- to 74-pint compressor models sold February 2009 to August 2017, 107 overheating/fire incidents, ~$17M property damage). That recall covers Ivation's older compressor units, not this desiccant model — but it is the brand's history and worth knowing |
| Connectivity | None on the base model — Ivation sells a separate Wi-Fi 'Smart' desiccant variant |
| Material | Not published by the manufacturer |
| Warranty | 12 months |
