Refreshing Printing Environment The ELEGOO MARS MATE air purifier, equipped with a special activated carbon filter, can efficiently remove irritating resin odors (up to 95% of volatile organic compounds) during the printing process, creating a refreshing environment for you. Liquid Operation With an extremely low power consumption of 6 W and an optimized fan structure, the air purifier operates with a lower noise level of 35 dB, making the cleaning process more energy-efficient and quieter. You can simply focus on your printing work while the air purifier runs quietly in the background. Filter Reset Reminder With an integrated VOC sensor to monitor VOC concentration and provide an intelligent warning message, you can reset the filter element using the filter reset button. When the sensor detects that the filter life is ≥ 1440 hours or the VOC concentration is ≥ 1.4 PPM, the AQI air quality indicator lights up red to remind you to replace the filter.
