The Quest 205 is a high-efficiency overhead dehumidifier designed to control excess humidity in basements, grow rooms, crawl spaces, and other moisture-prone areas. With its compact, ceiling-mounted design, powerful 205-pint per day moisture removal capacity, and ability to be attached to a duct, it's ideal for maintaining a dry and healthy environment in both residential and commercial settings.

High Efficiency

The Quest 205 dehumidifier is the most ideal product for commercial or agricultural environments due to its high efficiency. The new M-CoRR Technology is a patented multi-coil design that provides the highest efficiencies available. It uses a 2-inch MERV-11 filter, one of the most efficient filters. Additionally, the new refrigerant, R454B, makes the Quest 205 more environmentally friendly, enhancing why it's considered one of the best dehumidifiers on the market.

Versatile Applications

This high-efficiency dehumidifier adapts to any environment, offering excellent filtration and moisture removal in various settings, such as warehouses, offices, restaurants, and growing operations.

  • Hanging or Freestanding Installation: The unit can be installed as a freestanding dehumidifier with a corrosion-resistant base or suspended overhead if you don’t have floor space to spare.

Customer Questions
Who Makes Quest?
Quest dehumidifiers are proudly manufactured in the United States, specifically in Madison, Wisconsin. This is the home base of Therma-Stor LLC, the company behind the Quest brand. Therma-Stor has built a strong reputation in the HVAC and indoor air quality industries for producing high-performance, durable, and energy-efficient dehumidification systems.
Is installation difficult or do I need a professional?
While many Quest units are plug-and-play, larger models or those requiring overhead mounting may need a professional HVAC technician for safe and proper installation.
How do I know which Quest dehumidifier model is right for my space?
Start by measuring the square footage and ceiling height of your space. Then, consider moisture levels and how often the area is in use. Quest offers models with capacities ranging from around 70 to over 500 pints per day, so there’s an option for everything from small grow rooms to large industrial spaces.
What kind of maintenance is required?
Routine maintenance includes checking and replacing filters regularly, inspecting drainage lines, and cleaning the coils periodically. Most users find the upkeep simple and manageable.
How often do I need to clean or change the filter?
Most customers check the filter every 1–3 months. Depending on dust levels and usage, you may need to clean or replace it quarterly.
What is the warranty on Quest dehumidifiers?
Quest dehumidifiers come with a 5-year warranty on parts and refrigerant system components, offering long-term reliability and peace of mind.
How noisy are Quest dehumidifiers?
Noise levels vary by model, but most units are quiet enough for use in occupied commercial spaces. For grow rooms and workspaces, the sound is often comparable to a running HVAC system.
Can I run the dehumidifier continuously?
Yes, most Quest dehumidifiers are built for continuous operation. They include features like automatic defrost and humidity set points to maintain consistent performance without constant supervision.
