High Efficiency

The Quest 100 dehumidifier is the most ideal product for small spaces in commercial or agricultural environments because of its high efficiency. Weighing only 60 pounds and being 16 inches wide emphasizes the efficiency and compact design of this dehumidifier. The new M-CoRR Technology is a patented multi-coil design to help provide the highest efficiencies available. Equipped with a MERV-13 filter, one of the highest efficiency filters, it improves the overall moisture removal process. Additionally, the use of the new refrigerant, R454B, makes the Quest 100 more environmentally friendly, reinforcing why it’s considered one of the best dehumidifiers on the market.

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.
