Product Features: 3-Stage Filtration System
Each JORAIR R1 P1801 P1802 replacement filter incorporates a comprehensive 3-stage filtration system to effectively purify the air:
- Pre-filter: Captures larger particles such as dust, hair, pet fur, and lint, extending the life of the subsequent filters.
- HEPA Filter: Designed to capture 99.97% of airborne particles as small as 0.3 microns, including pet dander, pollen, and fine dust.
- Activated Carbon Filter: Absorbs various unpleasant odors and fumes, such as cooking smells, cigarette smoke, and volatile organic compounds (VOCs).

Installation Instructions
Follow these steps to install or replace your JORAIR HEPA filter:
- Power Off: Ensure your air purifier is turned off and unplugged from the power outlet before beginning installation.
- Access Filter Compartment: Locate and open the filter compartment cover on your air purifier. Refer to your air purifier's specific user manual for exact instructions on accessing the filter.
- Remove Old Filter: Carefully remove the used filter. It may be dusty, so handle it with care and dispose of it properly.
- Unpack New Filter: Remove the new JORAIR replacement filter from its protective packaging. Filters are sealed to protect their lifetime.
- Insert New Filter: Insert the new filter into the compartment, ensuring it is oriented correctly. The filter should fit snugly.
- Close Compartment: Close the filter compartment cover securely.
- Restore Power: Plug the air purifier back into the power outlet and turn it on.
- Reset Filter Indicator (if applicable): If your air purifier has a filter replacement indicator, follow the manufacturer's instructions to reset it.
Maintenance and Replacement
To ensure optimal performance and air quality, regular filter replacement is essential.
- Replacement Frequency: It is recommended to replace the JORAIR R1 P1801 P1802 HEPA Filter every 3-6 months. This duration may vary depending on air quality, usage frequency, and environmental factors (e.g., presence of pets, smoking, high pollution levels).
- Visual Inspection: Periodically inspect the filter for visible signs of dirt, dust accumulation, or discoloration. A heavily soiled filter indicates it's time for replacement.
- Performance Decline: If you notice a decrease in air purifier performance, increased odors, or reduced airflow, it may be an indication that the filter needs to be replaced sooner.

Troubleshooting
If you encounter issues after replacing your filter, consider the following:
- Filter Indicator Light Remains On: After replacing the filter, some air purifiers require a manual reset of the filter indicator light. Consult your air purifier's user manual for specific instructions on how to reset the filter life monitor.
- Reduced Airflow or Unusual Noise: Ensure the filter is correctly seated in its compartment and the cover is securely closed. An improperly installed filter can lead to reduced efficiency or noise.
- Persistent Odors: If odors persist after filter replacement, verify that the new filter was removed from all packaging. If the issue continues, the air quality in the environment might be exceptionally poor, requiring more frequent filter changes, or there might be another source of odor not addressed by the filter.
