Sovol Filament Dryer SH02 Dual-Spool Dry Box - Fast Heating and Sealed

In this review of the Sovol Filament Dryer SH02, the bottom line is simple: it is a practical, budget-friendly filament storage and drying solution for hobbyists and small shops who need reliable moisture control for 1KG spools. The SH02 stands out for its dual-spool capacity and faster 150W PTC heater, which together solve the most common filament frustration - inconsistent prints caused by damp filament - while remaining easy to use with one-key presets for common materials.

Key Features

• Dual spool capacity: The box can hold and dry two 1KG spools at once, saving space and allowing two printers or two materials to be served simultaneously.
• 150W PTC fast heater: The upgraded heater reaches 50C in about 7 minutes and 70C within 25 minutes for quicker drying cycles and better throughput.
• 360 circulation fan: Built-in fan circulates hot air evenly so filament dries uniformly and moisture pockets are reduced.
• Improved sealing: Thicker sealing materials and a revised gasket design protect filament from ambient moisture and dirt even when the unit is powered off.
• One-key material presets: Nine preset temperature/time profiles for PLA, TPU, PETG, ABS and others make setup immediate and reduce guesswork for different filament types.
• Smart safety protection: Automatic PTC cutoff and alarm for fan failure help prevent overheating and protect the heater element.

Who It's For

The SH02 is best for hobbyists, educators, and small print shops that work with standard spool sizes and want a straightforward, hands-off way to keep filament dry. Its ability to host two rolls makes it useful for users who run dual printers or keep a backup spool ready without dedicating extra bench space.

Those who need industrial-scale drying, accommodate very large spools, or require ultra-quiet operation may want to look elsewhere; the SH02 prioritizes fast heating and effective circulation over whisper-quiet operation, and its design fits standard 1KG spools and PTFE feed tubing.

Pros & Cons

Pros

• Dual-roll drying lets you maintain two active spools or support two printers from one unit.
• Faster 150W PTC heater reduces preheat time and shortens drying cycles compared with previous models.
• Intuitive one-key presets remove the need to manually set temperature and time for common filament types.
• Sturdy sealing and space for desiccant bags improve long-term filament protection when not powered.

Cons

• Fan noise has mixed feedback from users, so it may be noticeable during quiet work sessions.
• Box is designed for 1KG spools and PTFE-fed setups; oversized spools or nonstandard feeds may not fit without modification.

Our Verdict

The Sovol SH02 is a solid, affordable filament dryer that delivers faster heating and the convenience of dual-spool drying, making it a strong choice for hobbyists and small shops who need reliable moisture control. Its preset profiles, improved sealing, and safety features provide good value for the price, though users sensitive to fan noise or those needing nonstandard spool support should verify fit and sound levels before buying.

Frequently Asked Questions

Can it dry two different filament types at once?
Yes, the SH02 can hold and dry two 1KG spools simultaneously; use appropriate presets for each material and monitor drying time if the materials require different profiles.

How fast does it warm up?
With the 150W PTC heater, expect roughly 50C in about 7 minutes and about 70C within 25 minutes under typical conditions.

Is desiccant included?
No, desiccant bags are not included, but the box accommodates up to four bags to improve drying efficiency and long-term storage.
