Purification Technology
The Core300 Pro utilizes patented VortexAir 3.0 technology and 11 centrifugal fans to significantly enhance suction power. It can purify an 8-tatami room in approximately 13 minutes at maximum airflow. The air purification capacity supports rooms up to 20 tatami mats (approximately 33 square meters).

4. Maintenance
Filter Cleaning and Replacement
The Core300 Pro uses a high-performance integrated filter designed to capture 0.1µm particles with 99.97% efficiency and achieve 99.99% sterilization. This filter consists of four layers:
- Pre-filter: Captures large particles like hair and dust.
- Activated Carbon Filter: Removes various odors including tobacco, cooking smells, and pet odors.
- Sterilization Coat: Suppresses harmful substances like viruses and bacteria.
- Electrostatic HEPA Filter: Strongly removes pollen, dust mites, bacteria, and mold.

- Pre-filter Cleaning: The pre-filter should be cleaned every 2-4 weeks to maintain purification efficiency and extend the overall filter life. Use a soft brush or vacuum cleaner to remove accumulated dust.
- Filter Life: The filter's stated lifespan is 2 years, but the recommended replacement guideline is every 6-12 months, depending on usage and air quality.
- Filter Check Lamp: If the filter check lamp illuminates, it does not always mean immediate replacement is required. First, clean the filter and then reset the filter life indicator. If the lamp remains lit after resetting, then filter replacement is necessary.
