Product Overview
This FilterTech Premium Replacement Water Filter Set is designed to provide clean, great-tasting water by effectively removing impurities and contaminants. The set includes multiple stages of filtration to ensure optimal water quality for your compatible Coway water purifier models.
Image: A set of four distinct water filters. From left to right, they are labeled "SEDIMENT", "PRE-CARBON", "RO/MEMBRANE" (partially visible), and "POST CARBON". Each filter is white with a colored label indicating its type and function.
The filtration process typically involves a sediment filter to remove larger particles, a pre-carbon filter to absorb chlorine and organic chemicals, an RO/membrane filter for fine purification, and a post-carbon filter for final taste and odor enhancement.
Important Safety Information
- Always turn off the water supply to your water purifier before attempting to replace filters.
- Disconnect the power supply to the unit before filter replacement.
- Ensure all connections are secure to prevent leaks after installation.
- Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
Setup and Installation
Filter replacement procedures may vary slightly depending on your specific Coway model. Refer to your Coway water purifier's original manual for detailed instructions on accessing and removing old filters. The general steps are as follows:
- Prepare: Turn off the water supply valve to the purifier and unplug the unit from the power outlet.
- Access Filters: Open the filter compartment cover on your Coway water purifier.
- Remove Old Filters: Carefully twist or pull out the old filters according to your purifier's design. Be prepared for some residual water to drip.
- Install New Filters: Insert the new FilterTech replacement filters into their respective slots. Ensure they are correctly oriented and securely seated. The filters are typically labeled (e.g., Sediment, Pre-Carbon, Post-Carbon) to guide correct placement.
- Secure: Close the filter compartment cover.
- Restore Power: Plug the unit back into the power outlet and slowly turn on the water supply valve.
- Flush Filters: This is a critical step. Allow water to flow through the system for approximately 2 minutes (about 4 liters) for each filter. This flushes out any carbon powder (charcoal powder) from the manufacturing process and purges air from the system. Repeat this flushing process for each newly installed filter.
- Check for Leaks: Visually inspect all connections and the filter compartment for any signs of leaks.
Note: The initial water dispensed after installation and flushing may appear cloudy or contain black specks. This is normal and will clear up after further flushing. Do not consume this initial water.
Operating Instructions
Once the new filters are installed and flushed, your Coway water purifier is ready for normal operation. The filters work automatically as water passes through the system.
- Ensure the water purifier is connected to a power source and the water supply is turned on.
- Dispense water as you normally would with your Coway unit.
- Monitor the taste and clarity of the water. If any unusual taste or odor persists after initial flushing, continue flushing for a few more minutes.
Maintenance
Regular filter replacement is crucial for maintaining optimal water quality and the longevity of your water purifier. The lifespan of filters can vary based on water quality and usage.
Filter Replacement Schedule:
| Filter Type | Recommended Replacement Interval |
|---|---|
| Sediment Filter | Every 6-12 months |
| Pre-Carbon Filter | Every 6-12 months |
| RO/Membrane Filter | Every 24-36 months |
| Post-Carbon Filter | Every 12-18 months |
Note: These are general guidelines. Your Coway purifier may have indicator lights or alarms to signal when filters need replacement. Always follow the specific recommendations in your Coway purifier's manual.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water has unusual taste or odor after filter replacement. | Insufficient flushing of new filters. | Continue flushing the system for several more minutes until taste/odor improves. Ensure each filter was flushed for at least 2 minutes initially. |
| Slow water flow. | Air trapped in the system; clogged filters (if not new); kinked water line. | Flush the system to remove air. Check water lines for kinks. If filters are old, consider replacement. |
| Water leaking from filter compartment. | Filters not seated correctly; O-rings damaged or missing; compartment cover not properly closed. | Turn off water supply and power. Re-seat filters firmly. Check O-rings for damage and proper placement. Ensure compartment cover is securely latched. |
If problems persist, consult your Coway water purifier's original manual or contact FilterTech customer support.
