Quest Hi-E Dry 195 Portable Dehumidifier

Portable Hi-E Dry 195 Dehumidifier by Quest

The Hi-E Dry 195 removes up to 195 pints of moisture per day at 610 CFM and 13,400 BTU on standard 110-120V power, the larger of Quest's two Hi-E Dry portable models, built for grow rooms, drying chambers, and other climate-sensitive cultivation spaces.

It uses a MERV 11 filter, a step up from the Hi-E Dry 140's MERV 10, and stays in a fully portable format so it can move between rooms or drying setups rather than staying fixed in one location.

Key Features & Benefits

• 195 pints/day capacity — at 610 CFM and 13,400 BTU on standard 110-120V power, Quest's larger Hi-E Dry portable model.
• Portable format — moves between grow rooms, drying chambers, and other spaces rather than requiring a fixed overhead mount.
• MERV 11 filtration — captures dust, pollen, dander, mold spores, and smog at a rating matched to this unit's higher airflow.
• High-efficiency operation — delivers strong moisture removal per amp of power draw for a portable-format unit.
• Compatible with the Muffler Kit and Supply and Return Duct Kit — accessories are available for noise reduction and ducted operation when needed.

Who Should Use This

The Hi-E Dry 195 suits growers who need more capacity than the Hi-E Dry 140 in a portable format, particularly larger drying chambers or grow rooms where a fixed overhead unit isn't the right fit.

About Quest

Quest is a Therma-Stor brand. It focuses on commercial dehumidification. Therma-Stor is headquartered in Madison, Wisconsin. It's the same parent company behind the Anden brand. Therma-Stor has built dehumidifiers and environmental-control equipment for decades. Quest specifically targets commercial and industrial moisture control. Think indoor cultivation, food production, and commercial buildings. That's a different focus than residential basement units. Many overhead models use the company's patented M-CoRR design. M-CoRR stands for multi-coil refrigeration. The design recycles heat pulled from the air. That happens during dehumidification itself. It improves energy efficiency as a result. It also cuts heat sent back into the room.

Frequently Asked Questions

How does the Hi-E Dry 195 compare to the Hi-E Dry 140?

The 195 removes up to 195 pints/day at 610 CFM and 13,400 BTU with a MERV 11 filter, versus the 140's 135 pints/day at 300 CFM and 8,850 BTU with a MERV 10 filter. Choose based on the actual moisture load of your space rather than assuming the larger unit is always the safer choice.

Can this unit be ducted instead of running as free-standing?

Yes, Quest offers a Supply and Return Duct Kit compatible with the Hi-E Dry 195 for ducted installations. If you're planning a ducted setup, order the matching duct kit rather than assuming generic ductwork will connect directly.

Is a muffler kit available if operating noise is a concern?

Yes, Quest's Muffler Kit is compatible with the Hi-E Dry 195 and 120 and mounts onto the exhaust path to reduce operating noise, without affecting the unit's moisture removal capacity. It's a worthwhile add-on for installations in or near occupied workspaces.

What does the MERV 11 filter on this unit capture?

It captures dust, pollen, dander, mold spores, and smog particles at a rating one step above the MERV 10 filter used on the smaller Hi-E Dry 140. Replace it on a regular schedule to maintain the unit's rated airflow and moisture removal performance.
