3. Installation (Setup)

Follow these steps to correctly install the replacement filter in your U ULTTY CR021 Bladeless Air Purifier Tower Fan:

1. Power Off and Unplug: Before beginning, ensure your air purifier is turned off and unplugged from the power outlet for safety.
2. Access Filter Compartment: Refer to your CR021 Bladeless Air Purifier Tower Fan's main manual for specific instructions on how to open the filter compartment. Typically, this involves twisting or unlatching a cover at the base of the unit.
3. Remove Old Filter: Carefully remove the used filter from the compartment. Dispose of the old filter according to local regulations.
4. Insert New Filter: Place the new U ULTTY True HEPA Replacement Filter into the compartment. Ensure it is seated correctly and securely for a perfect air-tight seal. The 360° design allows for proper fit regardless of orientation.

4. Operating Principles

Once installed, the U ULTTY True HEPA Replacement Filter works in conjunction with your CR021 Bladeless Air Purifier Tower Fan to continuously clean the air. Air is drawn into the unit, passes through the multi-stage filtration system, and is then released as purified air. The filter's H13 HEPA layer and pre-filter work together to remove various pollutants, contributing to a healthier indoor environment.

5. Maintenance

Regular maintenance of your filter ensures consistent air purification performance.

• Filter Lifespan: The U ULTTY True HEPA Replacement Filter is designed to last approximately 3 months under normal usage conditions. This duration can vary based on air quality and frequency of use.
• Pre-Filter Cleaning: The ultra-fine nylon pre-filter can be gently brushed to remove larger particles like hair or pet fur. This practice helps extend the overall life of the HEPA filter. Do not wash the HEPA filter with water.
• Replacement Indicator: Your CR021 Bladeless Air Purifier Tower Fan will typically have an indicator light or notification to signal when the filter needs replacement. Always replace the filter when indicated, or every 3 months, whichever comes first, to maintain optimal air quality.

• Filter Indicator Still On: Ensure you have correctly reset the filter indicator by pressing and holding the power button on the remote control for 5 seconds after installation.
• Reduced Airflow: Verify that the filter is seated correctly and the compartment cover is securely closed. An improper seal can affect airflow.
• Unusual Noises: Check that the filter is properly installed and not obstructing any moving parts within the air purifier.
