One reviewer said, "The humidity quickly drops to 45-50%, and that distinctive musty smell from the wallpaper and flooring has significantly decreased."
Quieter Than a Library (approx. 628 users, 71%). The 34dB low-noise design allows comfortable use even at night. One reviewer mentioned, "The noise is almost non-existent. It's so quiet that running it during the day or at night doesn't bother anyone at all."
Grade 1 Efficiency for Low Electricity Costs (approx. 566 users, 64%). Dual inverter technology achieves Grade 1 energy efficiency, so running it all day doesn't burden your electricity bill.

Convenient Smart App Integration (approx. 451 users, 51%). The LG ThinQ app enables remote control even while away from home, enhancing daily convenience. One reviewer said, "I turn it on via ThinQ 30 minutes before getting home, and the house is fresh when I arrive. Remote mode changes and scheduling were especially useful during rainy season."
Excellent Laundry Drying Effect (approx. 442 users, 50%). Using the laundry drying mode, indoor laundry dries quickly without musty odors. One reviewer noted, "The laundry drying mode has significantly reduced drying time. I've started using it instead of a dryer."
Smooth-Rolling Casters (approx. 389 users, 44%). The 360-degree wheels roll very smoothly, making room-to-room transport easy. One reviewer said, "The wheels roll so smoothly. It feels like pushing a lightweight stroller - I can pull it with one hand, which is great."
What Are the Cons of This Product?
High Price Point (approx. 177 users, 20%). It's about $75-150 more expensive than similar products from other brands. Solution: Apply for the efficiency rebate (10%) to receive approximately $40 back, reducing the actual cost.
Tank Emptying Frequency (approx. 133 users, 15%). On humid days with extended operation, you'll need to empty the tank 1-2 times daily. Solution: Connect the continuous drainage hose (16mm inner diameter, sold separately) for uninterrupted operation without emptying.
Large and Heavy Unit (approx. 106 users, 12%). At 415x715x296mm and 16.7kg (37 lbs), it's heavy for one person to lift. Solution: The casters roll very smoothly, so pushing it to move is effortless.
Air Purification Kit Sold Separately (approx. 62 users, 7%). To use the air purification function, you must purchase a separate kit, and dehumidification efficiency may slightly decrease when using it. Solution: Use it purely for dehumidification and use a separate air purifier for air cleaning - this is more efficient.
Slower Performance in Large Open Spaces (approx. 53 users, 6%). Dehumidifying an entire 900+ sq ft space with all doors open takes longer. Solution: Close doors and focus dehumidification on one room at a time for faster humidity reduction.

Comparison Analysis
LG Whisen Objet Collection Strengths: The combination of maximum 20L dehumidification capacity, lowest 34dB noise level, and 10-year compressor warranty is the biggest advantage. The Objet Collection design also excels in interior harmony.
Compared to Winix Pposong: About $75 cheaper but with 16L capacity (smaller) and 38dB noise (louder). Winix is suitable for spaces under 710 sq ft or those with limited budgets.
Compared to Samsung Dehumidifier: Similar price and performance, but LG has advantages in dehumidification capacity (20L vs 18L) and noise (34dB vs 36dB). LG’s compressor warranty is also twice as long (10 years vs 5 years), making it more advantageous long-term.
What Are the Monthly Electricity Costs?
| Usage Pattern | Daily Usage | Estimated Monthly Cost |
|---|---|---|
| Occasional Use | 2 hours | ~$2 |
| Normal Use | 4 hours | ~$4 |
| Frequent Use | 8 hours | ~$8 |
| Heavy Rainy Season | 12+ hours | ~$12 |
Calculation Basis: 320W power consumption, $0.09/kWh electricity rate

Verdict: Should You Buy This Product?
Highly Recommended
The LG Whisen Objet Collection Dehumidifier 20L (DQ205PEGA) is the optimal choice for households in 650-1000 sq ft homes that need powerful dehumidification.
