Introduction
Thank you for choosing MORENTO HY4866 True HEPA Air Purifier Filters. These genuine replacement filters are designed to work seamlessly with your MORENTO HY4866 Air Purifier, ensuring certified fit and maximum filtration efficiency. They are crucial for maintaining a clean and healthy indoor environment by capturing airborne particles such as dust, pet dander, smoke, and pollen.

Setup and Filter Replacement
To ensure optimal performance and air quality, it is essential to replace your air purifier filters regularly. The MORENTO HY4866 filters are designed for easy replacement.
Filter Replacement Steps:
- Turn off and Unplug: Before beginning, turn off the air purifier and unplug it from the power outlet to ensure safety.
- Open Filter Covers: Locate the filter covers on the sides of the air purifier. Gently open them to access the old filters.
- Remove Old Filters: Carefully pull out the old filters. Note the orientation of the filters, especially the side marked "FRONT". Dispose of the used filters responsibly.
- Install New Filters: Remove the new filters from their protective plastic bags. Ensure the side marked "FRONT" on the filter element faces outward, and the active carbon face (black, honeycomb pattern) faces inward towards the purifier's fan. Insert the new filters firmly into their slots.
- Close Covers: Close the filter covers securely until they click into place.
- Power On and Reset: Plug the air purifier back in and turn it on. Press and hold the filter button for 5 seconds until you hear 3 beeps to complete the filter indicator light reset.

Operating Principles
The MORENTO HY4866 Air Purifier, when equipped with genuine filters, utilizes a multi-layer filtration system to effectively clean the air. This system includes an electrostatic cotton layer, a True HEPA filter, and honeycomb activated carbon particles.
- True HEPA Filtration: Captures at least 99.97% of airborne particles 0.3 microns in size, including dust, pollen, pet dander, and smoke.
- Activated Carbon: Absorbs odors and harmful gases, providing fresher air.
- Double-Sided Air Intake: The air purifier draws air from two sides, enhancing purification efficiency.


Maintenance
Regular filter replacement is crucial for maintaining the efficiency and lifespan of your MORENTO HY4866 Air Purifier. The lifespan of a genuine MORENTO replacement filter is generally 2200 hours.
- Replacement Frequency: It is recommended to replace the filter every 3 to 6 months, depending on your usage and the air quality in your environment. The air purifier's display will indicate when a filter change is due.
- Filter Indicator Reset: After replacing the filter, always remember to reset the filter indicator by pressing and holding the filter button for 5 seconds until you hear 3 beeps. This ensures accurate tracking of the new filter's lifespan.

Troubleshooting
If you encounter issues with your MORENTO HY4866 filters or air purifier, consider the following common solutions:
- Poor Filtration Performance: If the air quality does not seem to improve after extended use, check if the filters are installed correctly and if they are genuine MORENTO filters. Non-genuine filters may not fit properly or meet HEPA standards.
- Filter Indicator Light Remains On After Replacement: Ensure you have correctly performed the filter reset procedure. Turn off the device, unplug it, then plug it back in and press and hold the filter button for 5 seconds until you hear 3 beeps.
- Unusual Odors: If new or persistent odors are present, the activated carbon layer of the filter may be saturated. Consider replacing the filters, even if the indicator light has not yet signaled a change, especially in environments with high levels of pollutants or strong odors.
