3. Product Features
The JORAIR HEPA Filter Replacement features a high-efficiency 4-in-1 filtration system designed to capture a broad spectrum of airborne contaminants:
- Ultra-fine Pre-Filter: Captures larger particles such as dust, hairs, pet fur, and lint, extending the lifespan of subsequent filters.
- HEPA Filter: Traps up to 99.97% of airborne particles as small as 0.3 microns, including dust, pet dander, and pollen.
- Activated Carbon Filter: Effectively absorbs unwanted odors, fumes, smoke, and cooking smells, as well as pet odors, improving overall air freshness.
- Bracket Layer: Provides structural support for the filter system.
This multi-stage filtration works synergistically to provide cleaner, fresher air, making it ideal for households with pets, smokers, or those living in urban environments.

4. Setup and Installation
To ensure optimal performance, follow these general steps for replacing the filter in your Envion Therapure Air Purifier. For specific instructions, always refer to your air purifier's original user manual.
- Power Off: Unplug your Envion Therapure Air Purifier from the power outlet before beginning any maintenance.
- Access Filter Compartment: Locate and open the filter compartment cover on your air purifier. This usually involves unlatching or unscrewing a panel.
- Remove Old Filter: Carefully remove the used filter. It may be dusty, so handle it over a waste bin.
- Install New Filter: Insert the new JORAIR HEPA Filter Replacement into the compartment, ensuring it is oriented correctly according to your air purifier's design. The filter should fit snugly.
- Close Compartment: Securely close the filter compartment cover.
- Power On: Plug your air purifier back into the power outlet.
- Reset Filter Indicator (if applicable): If your air purifier has a filter replacement indicator light, follow your air purifier's manual to reset it.
5. Operating Principles
Once installed, the JORAIR HEPA Filter Replacement works seamlessly with your Envion Therapure Air Purifier to continuously clean the air in your environment. Air is drawn into the purifier, passes through the multi-stage filtration system, and then clean air is released back into the room. The filter's design ensures efficient airflow while maximizing particle and odor capture.

6. Maintenance
Regular filter replacement is crucial for maintaining the efficiency and effectiveness of your air purifier. An old, clogged filter can significantly reduce your air purifier's performance and air quality output.
- Replacement Schedule: It is recommended to replace the JORAIR HEPA Filter every 6 months under normal operating conditions. This timeframe may vary depending on air quality, usage frequency, and the presence of pets or smokers.
- Disposal: Dispose of used filters according to local waste disposal guidelines.

7. Troubleshooting
If you experience issues after replacing your filter, consider the following common points:
- Reduced Airflow: Ensure the filter is installed correctly and the compartment cover is fully closed. Check if the filter is genuinely new; an old filter will restrict airflow.
- Persistent Odors: While the activated carbon filter is highly effective, very strong or unusual odors might indicate a need for more frequent filter changes or an external source of odor.
- Filter Indicator Light: If the filter replacement indicator light remains on after installation, refer to your air purifier's manual for specific instructions on how to reset it. This often involves pressing and holding a button for a few seconds.
- General Performance Issues: If the air purifier itself is not functioning correctly, consult its original manual or contact the air purifier manufacturer for support.
