Please read this manual thoroughly before use.
2. Product Overview
The CFS WF813 ReliOn Humidifier Wick Filter is designed to fit ReliOn humidifier models RCM-832 and RCM-832N. This high-performance wick filter utilizes honeycomb filtration to efficiently trap mineral pollutants present in water, preventing them from being released into your home's air. Each box contains two filters, ensuring you have a replacement readily available.

3. Setup and Installation
Follow these general steps to install or replace the wick filter in your compatible ReliOn humidifier:
- Power Off: Ensure your humidifier is unplugged from the power outlet before beginning any installation or maintenance.
- Access Filter Compartment: Refer to your humidifier's specific manual for instructions on how to open the filter compartment. This usually involves removing the water tank or the top cover.
- Remove Old Filter: Carefully remove the used wick filter. Dispose of it according to local regulations.
- Unpack New Filter: Remove the new CFS WF813 wick filter from its packaging.
- Install New Filter: Place the new filter into the designated compartment. Ensure it is seated correctly and securely. The filter measures approximately 3 3/4 inches by 5 1/2 inches by 1 1/2 inches.
- Reassemble Humidifier: Close the filter compartment and reassemble any parts removed during the process.
- Fill Water Tank: Fill the humidifier's water tank with clean, cool water.
- Power On: Plug the humidifier back into the power outlet and turn it on.
It is recommended to allow the new filter to soak in water for approximately 15-30 minutes before initial use to ensure optimal wicking performance.
4. Operating Guidelines
Once the filter is installed, operate your humidifier according to the manufacturer's instructions. The CFS WF813 wick filter will begin to absorb water and release moisture into the air. Monitor the humidity levels in your room to maintain a comfortable environment.
5. Maintenance
Regular maintenance of your wick filter is crucial for efficient humidifier operation and air quality.
- Replacement Frequency: For optimum performance, replace the CFS WF813 wick filter at the beginning of each humidifying season or every two months, depending on usage and water hardness. Hard water areas may require more frequent replacement due to increased mineral buildup.
- Mineral Buildup: The filter is designed to trap mineral pollutants. Over time, these minerals will accumulate on the wick, reducing its efficiency. A visible white or crusty buildup indicates the need for replacement.
- Cleaning: While some light rinsing may extend the life slightly, wick filters are generally not designed for thorough cleaning. Attempting to scrub or aggressively clean the filter can damage its structure and reduce its effectiveness. Replacement is the most effective solution for maintaining performance.
6. Troubleshooting
If you experience issues with your humidifier after installing a new filter, consider the following:
- Reduced Humidity Output: If the humidifier is not producing enough moisture, check if the filter is properly saturated. Ensure it has had sufficient time to soak in water. A heavily mineralized or old filter will also reduce output; replace if necessary.
- Unusual Odors: New filters may have a slight initial odor that dissipates quickly. Persistent or foul odors could indicate bacterial growth in the water tank or on the filter. Clean the humidifier thoroughly and replace the filter.
- Filter Not Wicking Water: Ensure the filter is correctly seated and fully submerged in the water reservoir. If the filter is dry or only partially wet, it cannot properly humidify.
