5. Maintenance
Regular filter replacement is crucial for maintaining your humidifier's performance and ensuring clean, healthy humidification.
- Replacement Frequency: Replace your HQRP wick filter every 2 to 3 months.
- Factors Affecting Life: The actual lifespan of the filter can vary depending on usage frequency, local water hardness, and air quality. Hard water will cause mineral buildup more quickly, necessitating more frequent replacement.
- Visual Inspection: Regularly inspect the filter for signs of mineral buildup, discoloration, or hardening. Replace it immediately if these signs are present.
6. Troubleshooting
If you experience issues with your humidifier after filter replacement, consider the following:
- Low Humidity Output: Ensure the filter is fully saturated with water. If the filter is old or heavily calcified, replace it. Check that the humidifier fan is operating correctly.
- Unpleasant Odor: An odor can indicate bacterial growth or mold. Replace the filter and thoroughly clean the humidifier's water tank and base with a suitable cleaning solution.
- Filter Not Absorbing Water: Ensure the filter is correctly installed and fully submerged in the water reservoir. If the filter is new and still not absorbing, check for any packaging that might be obstructing water flow.
