ELEGOO Mars Mate Air Purifier
The ELEGOO Mars Mate Air Purifier is a large external filtration unit specifically engineered for resin 3D printing.


It connects directly to the printer via a flexible hose, extracting air from inside the build chamber to capture volatile organic compounds (VOCs) and strong resin odors at the source before they disperse into the workspace.
​High-density filtration for clean air
| | | Unlike small USB purifiers placed under the hood, the Marsmate connects directly to your compatible printer via a flexible hose. Air laden with resin residue is drawn out of the printing chamber and passes through a high-density activated carbon filter. | |
High-Density TVOC Filtration (95% Efficiency)
The core of the Marsmate is its oversized CTC100 columnar activated carbon filter. Featuring a composite black dense mesh on both sides, this high-capacity cartridge is capable of absorbing up to 95% of Total Volatile Organic Compounds (TVOCs), including pungent resin odors and formaldehyde. This ensures that the air exhausted into your workshop is thoroughly scrubbed of airborne irritants.

Smart features: VOC sensor and filter reminder
The touch control panel includes a built-in VOC sensor that analyzes air quality in real time. The AQI light ring informs you:
 | | Green: Excellent quality (<0.7 ppm) Yellow: Moderate quality (0.7–1.4 ppm) Red: Poor quality or filter replacement needed (≥1.4 ppm or 1,440 hours of use) | |  |
Auto mode alternates 10 minutes at high speed and 50 minutes at low speed every hour, optimizing purification and quiet operation. A dedicated button resets the counter after filter replacement (long press 3 seconds).
Ultra-quiet and economical
With a noise level measured at 35 dB – equivalent to a quiet library – the Marsmate operates without disrupting your workspace. Its power consumption is limited to 6W (12V 0.6A power supply), allowing it to run 24/7 with negligible impact on your electricity bill.


Controls and Operating Modes
The intuitive touch control panel includes four buttons: On/Off (short press to turn on, long press 3 seconds to turn off) Fan speed (toggle between low and high; indicated by one or two lights)
Auto mode: Intelligent hourly cycle with 10 minutes at high speed and 50 minutes at low speed
Filter reset (long press 3 seconds after installing a new filter)

Installation and Compatibility
The package includes everything needed for direct connection: connector hose, adapter, connector seat, 4 screws, 4 nuts, Allen wrench, and open-end wrench. Installation involves removing the rear exhaust panel on the printer (typically held by 4 screws) and attaching the provided seat and hose for an airtight seal.
It is compatible with ELEGOO resin printers featuring an extension port, including the Mars 4 DLP, Mars 4 MAX, Mars 5 series, Saturn 2, Saturn 3 / 3 Ultra, Saturn 4 series, Saturn 8K, Jupiter, and Jupiter SE. It can also be adapted for use with many other resin printers or positioned nearby without direct connection.
Maintenance Tips
 
| | Remove the protective plastic bag from the new filter before first use. Wipe the exterior with a soft cloth.
Vacuum the filter surface monthly (do not wash with water). After replacing the filter, reset the counter using the dedicated button. |
The Mars Mate delivers effective odor and VOC reduction while operating quietly and with minimal energy use, helping maintain a more comfortable and cleaner printing environment for regular resin users.
