How this dehumidifier scores for different use cases
At 16.78 lbs with compact 7.1 x 9.7 x 16.1 inch dimensions, this unit is well-suited for RVs, bathrooms, and closets. The manufacturer specifically lists RVs and boats as recommended uses.
The 36 dB noise level is quiet enough for bedrooms, and it includes sleep mode. Its compact size fits well in living spaces, though it lacks a display-off feature in the specs.
At 21 pints per day, this unit handles light basement moisture but falls short for seriously damp basements. It has continuous drain and auto-defrost, which help, but the 1600 sq ft coverage and small 2-liter tank limit its basement effectiveness.
21 pints per day and 1600 sq ft coverage are far too limited for whole-house dehumidification. No Wi-Fi control or pump option makes set-and-forget operation difficult across a full home.
No Wi-Fi connectivity, no app control, and no voice assistant compatibility. This unit offers only a basic digital control panel with no smart home features.
At 21 pints per day with a 2-liter tank, this unit is designed strictly for residential use. It lacks the capacity, durability features, and power needed for commercial or industrial applications.
Our Verdict
The Glowells PD20A removes 21 pints of moisture per day. That works for bedrooms, bathrooms, and RVs. It struggles in large or very damp basements.
You get three useful modes. DEHU mode lets you set target humidity from 30% to 80%. Continuous mode pairs well with the included drain hose.
At 36 dB, this is one of the quieter units you can buy. Sleep mode makes it even better for bedrooms. You can run it at night without losing sleep.
The 16.78 lb body rolls on four caster wheels. A side handle helps you carry it between rooms. It fits easily in an RV or small bathroom.
No Wi-Fi or app control exists on this model. You must adjust settings on the unit itself. Smart home users should look elsewhere.
At $119.99, you pay a fair price for a small-space dehumidifier. The drain hose and auto features add real convenience. You get solid value if your space is under 1000 sq ft.
What We Like
- Runs at just 36 dB, quieter than most dehumidifiers in this class
- Weighs only 16.78 lbs with 4 caster wheels and a side handle for easy moving
- Includes continuous drain hose so you never have to empty the tank manually
- Three modes (DEHU, Dry, and Continuous) let you match operation to your humidity needs
- Compact 7.1 x 9.7 x 16.1 inch body fits in tight spaces like RVs and bathrooms
What Could Be Better
- No Wi-Fi or app control for remote monitoring and adjustment
- 21 pints per day capacity is below average for spaces over 1000 sq ft
- 2-liter tank is small and fills up fast without the drain hose connected
- No built-in pump for upward drainage to sinks or windows
- Only 2 fan speeds, while many competitors offer 3 or more
