Operating (When to Replace)
For optimal performance and to maintain effective suction, it is recommended to regularly check and replace your vacuum cleaner's filter. The frequency of replacement depends on usage, but generally, filters should be replaced every 3 to 6 months, or more frequently if you notice a decrease in suction power or if the filter appears heavily soiled or damaged.
Maintenance (Cleaning)
To extend the life of your ZYWUOY replacement filter and ensure continued performance, regular cleaning is essential. Follow these steps:
- Remove the filter from the vacuum cleaner as described in the "Setup (Installation)" section.
- Tap the filter gently over a waste bin to remove loose dirt and debris.
- Rinse the filter under cool, running water until the water runs clear.
- Allow the filter to air dry completely for at least 24 hours before reinserting it into the vacuum cleaner. Ensure it is completely dry to prevent mold or mildew growth and to maintain filtration efficiency.
- Do not use detergents or hot water, and do not machine wash or tumble dry the filter.

Troubleshooting
Reduced Suction Power
If you experience a noticeable decrease in your vacuum cleaner's suction power, the filter may be clogged. Try the following:
- Remove and clean the filter as described in the "Maintenance" section.
- Ensure the filter is completely dry before reinstallation.
- If cleaning does not restore suction, it may be time to replace the filter with a new one.
Unusual Odors
If your vacuum cleaner emits unusual odors, the filter might be retaining moisture or debris. Clean the filter thoroughly and ensure it is completely dry before reinstallation. If the odor persists, consider replacing the filter.
