2. Setup and Installation
The CPAI Replacement Filter is designed for easy installation without the need for additional tools. Follow these steps to replace your vacuum cleaner's filter:
- Ensure your Ryobi 18V ONE+ Wet/Dry Vacuum Cleaner is turned off and unplugged (if applicable) or has its battery removed.
- Open the vacuum cleaner's canister to access the existing filter.
- Carefully remove the old filter. Dispose of it according to local regulations.
- Insert the new CPAI Replacement Filter into the designated slot, ensuring it is securely seated. The filter is designed to fit precisely into the vacuum's frame.
- Close the vacuum cleaner's canister securely.
Important Note on Foam Sleeves:
If your vacuum cleaner uses a foam sleeve (e.g., 90585 type), it should be used separately from the pleated filter (e.g., 90304 type). Never use both the pleated filter and the foam sleeve at the same time. Placing the foam sleeve on the outside of the pleated filter can damage both components and impair filtration performance.

3. Operating the Vacuum with the New Filter
Once the new filter is installed, your vacuum cleaner is ready for operation. The CPAI Replacement Filter provides high-efficiency filtration, effectively capturing dust, debris, pet hair, wood chips, and flocculent materials. This ensures cleaner exhaust air and maintains the suction power of your vacuum.

4. Maintenance
To ensure optimal performance and longevity of your CPAI Replacement Filter, regular cleaning is recommended. The filter is washable and reusable.
Cleaning Instructions:
- Remove the filter from the vacuum cleaner.
- Gently tap the filter against a hard surface to dislodge loose dirt and debris.
- Rinse the filter under running water until the water runs clear. Avoid using harsh detergents or brushes that could damage the filter material.
- Allow the filter to air dry completely before reinstalling it into the vacuum cleaner. Ensure it is thoroughly dry to prevent mold or mildew growth and to maintain filtration efficiency.
It is recommended to clean the filter every 6-9 months, or more frequently depending on usage and the type of debris being vacuumed, for optimum performance.

5. Troubleshooting
If you experience reduced suction or unusual noises from your vacuum cleaner after installing the new filter, consider the following:
- Check Filter Installation: Ensure the filter is correctly and securely seated in the vacuum's canister. A loose filter can lead to air leaks and reduced suction.
- Filter Cleanliness: Even new filters can sometimes accumulate debris quickly depending on the environment. If suction is low, remove and inspect the filter for any blockages.
- Vacuum Canister Seal: Verify that the vacuum cleaner's canister lid is properly closed and sealed.
- Hose and Attachments: Check the vacuum hose and any attachments for blockages or damage.
If issues persist after checking these points, refer to your vacuum cleaner's original instruction manual or contact the manufacturer for further assistance.
