GermGuardian FLT4825 HEPA Filter

The FLT4825 is specifically designed for GermGuardian models that utilize the 'Filter B' system, such as the AC4825, AC4300BPTCA, and CDAP4500BCA series. Always check the model number printed on the back or bottom of your air purifier unit to confirm compatibility before purchasing.

This is a genuine GermGuardian replacement filter. Using authentic manufacturer parts ensures the filter fits correctly and maintains the specific airflow and filtration standards your device was engineered to meet.

For optimal air quality and to keep your purifier running efficiently, it is recommended to replace the filter every 6 to 8 months. This timeframe may vary depending on your local air quality and how frequently you run the device.

No, this HEPA filter is not washable or reusable. Attempting to clean it with water or a vacuum can damage the delicate filter media and compromise its ability to capture fine particles.

The FLT4825 is primarily the HEPA filter component. Depending on your specific model, you may need to purchase the carbon pre-filter separately or ensure your current pre-filter is still in good condition when you swap out the main HEPA unit.
