- Nylon Preliminary Filter: Captures large particles such as dust, lint, hair, and pet fur, extending the life of subsequent filters.
- H13 True HEPA Filter: Designed to capture 99.97% of airborne particles as small as 0.3 microns, including pet dander, pollen, and fine dust.
- Activated Carbon Filter: Absorbs various household odors, cooking fumes, volatile organic compounds (VOCs), and wildfire gases.
This multi-layer defense system works synergistically to provide cleaner, fresher air in your living environment.

4. Maintenance
To ensure optimal performance and longevity of your air purifier and filter, regular maintenance is recommended:
- Filter Replacement: It is recommended to replace the filter every 6-8 months. This duration may vary depending on your usage frequency and the air quality in your environment.
- Pre-filter Cleaning: For best results, vacuum the preliminary filter layer every 2-4 weeks to remove accumulated dust and debris. This helps maintain filtration efficiency and extends the overall life of the filter.
5. Troubleshooting
If you encounter any issues with your isinlive Core 300 Replacement Filter, consider the following:
- Filter Indicator Light Remains On After Replacement: Ensure you have pressed and held the "Check Filter" indicator button for at least 3 seconds until it blinks and turns off. If the issue persists, try unplugging the purifier for a minute and then repeating the reset process.
- Decreased Airflow or Odor Persistence: This may indicate that the filter is heavily soiled and needs replacement sooner than the recommended 6-8 months, especially in environments with high pollution, pets, or strong odors. Ensure the filter is correctly seated and the cover is securely locked.
- Unusual Noise: Check if the filter is properly installed and not loose within the purifier. Ensure no foreign objects are obstructing the air intake or output.
