How this dehumidifier scores for different use cases
At 17.91 lbs with a carry handle and compact 8.5 x 12.5 x 19.5 inch footprint, this is purpose-built for small spaces. The 410 sq ft coverage and continuous drain option suit closets, RVs, and boats perfectly.
Desiccant dehumidifiers run quieter than compressor models. This unit offers sleep mode, a dimmable LCD screen, and compact size suitable for bedrooms up to 410 sq ft.
At 19 pints per day and 410 sq ft coverage, this unit lacks the capacity for most basements. It has continuous drain but no auto-defrost, though its desiccant technology works down to 33°F which partially compensates.
With only 19 pints per day and 410 sq ft coverage, this unit cannot handle whole-house dehumidification. It lacks wheels, pump drain, and the capacity needed for large areas.
This unit has no Wi-Fi, no app control, and no voice assistant compatibility. It offers only manual LCD controls with no smart home integration whatsoever.
At 19 pints per day with a 0.75-gallon tank, this unit is far too small for any commercial or industrial application. It lacks the capacity, durability features, and drainage options required.
Our Verdict
The Ivation 19-Pint Desiccant Dehumidifier fills a specific niche. It targets small, cold spaces where compressor models struggle or fail.
Desiccant technology is the standout here. It pulls moisture from air as cold as 33°F. That makes it ideal for unheated attics, crawlspaces, and garages in winter.
At 17.91 lbs, you can carry it between rooms with one hand. The 8.5 x 12.5 inch footprint tucks into tight corners. It fits where bigger units simply cannot.
The continuous drain hose adds real convenience. Connect it and walk away. No more emptying a tiny 0.75-gallon tank multiple times per day.
Sleep mode and a dimmable screen help in bedrooms. Desiccant motors tend to run quieter than compressor units. You can sleep with it running nearby.
The price is the tough part. At $289.99 for 19 pints per day, you pay a premium. A 35-pint compressor dehumidifier costs about the same or less.
You also get zero smart features. No Wi-Fi. No app. No voice control. Everything happens on the LCD panel.
This unit makes sense if you need dehumidification in cold conditions below 41°F. For warm basements or large rooms, a compressor model gives you more capacity per dollar.
What We Like
- Desiccant technology works in cold temps down to 33°F, perfect for unheated spaces like attics and crawlspaces.
- Weighs only 17.91 lbs with a built-in carry handle for easy room-to-room moves.
- Includes continuous drain hose so you never need to empty the water tank.
- Sleep mode and dimmable LCD screen let you run it at night without bright lights.
- Compact 8.5 x 12.5 inch footprint fits tight spaces like closets, boats, and RVs.
What Could Be Better
- No wheels make it harder to slide across floors despite the carry handle.
- No Wi-Fi, app control, or smart home features of any kind.
- The 0.75-gallon tank fills fast at 19 pints per day without continuous drain connected.
- No auto-defrost feature, though desiccant design reduces frost buildup compared to compressor units.
- At $289.99 for 19 pints per day, the price per pint is high compared to larger compressor models.

Frequently Asked Questions
Common questions aboutIvation 19 Pint Small-Area Desiccant Dehumidifier Compact and Quiet - with Continuous Drain Hose for Smaller Spaces, Bathroom, Attic, Crawlspace and Closets - for Spaces Up to 410 Sq Ft
How does a desiccant dehumidifier differ from a compressor model?
A desiccant unit uses a moisture-absorbing rotor instead of a refrigerant compressor. This lets it work in colder temperatures down to 33°F and run more quietly. Compressor models are more energy efficient in warm conditions but struggle below 41°F.
What size room can the Ivation 19-pint dehumidifier handle?
Ivation rates this unit for spaces up to 410 square feet. That covers a typical bedroom, bathroom, large closet, RV, or small attic space.
How often do I need to empty the water tank?
The tank holds 0.75 gallons. At full 19-pint capacity, you would need to empty it roughly 3 times per day. You can avoid this entirely by connecting the included continuous drain hose.
Can I use this dehumidifier in my basement?
It can work in small basement areas under 410 sq ft, especially unheated basements where temperatures drop below 41°F. For larger basements, a 35-50 pint compressor model would remove moisture much faster.
Does this dehumidifier warm up the room?
Yes. Desiccant dehumidifiers release warm, dry air as a byproduct of the drying process. The manufacturer notes it warms ambient air, which is a benefit in cold spaces but a drawback in warm rooms.
