Product Features
The GREE GCF300ANSA replacement filter utilizes a multi-stage filtration system to effectively purify indoor air.
3-Stage Filtration System:
- Fine Preliminary Filter: Captures larger particles such as hair, dust, pet dander, and lint.
- Activated Carbon Filter: Absorbs various household odors and Volatile Organic Compounds (VOCs), including cooking smells, pet odors, cigarette smoke, and formaldehyde.
- H13 True HEPA Filter: Traps 99.97% of the finest particles as small as 0.3 microns, including pollen, dust mites, mold spores, allergens, and other harmful particles like PM2.5.

Maintenance
Regular filter replacement is crucial for maintaining the efficiency and performance of your GREE Air Purifier.
- Filter Lifespan: The GREE GCF300ANSA filter typically lasts between 6 to 8 months, depending on air quality and usage frequency. The air purifier's filter indicator light will signal when a replacement is needed.

Troubleshooting
If you encounter issues after replacing your filter, consider the following:
- Filter Indicator Light Remains On: Ensure you have correctly performed the filter reset procedure (Step 8 in Installation Instructions). If the light persists, repeat the reset.
- Reduced Airflow or Unusual Noise: Verify that the new filter is installed correctly and seated snugly. Ensure the front grille cover is securely closed. Check for any obstructions around the air intake or outlet.
- Persistent Odors: While the activated carbon filter is highly effective, some strong, lingering odors may take time to dissipate. Ensure the room is adequately ventilated initially. If odors persist after a few days of operation, verify the filter is genuine and installed correctly.
- Air Purifier Not Turning On: Check the power connection. Ensure the front grille cover is fully closed, as some models have a safety switch that prevents operation if the cover is open.
