Setup and Installation
Follow these steps to properly install your new Filter-Monster HEPA filters into your Therapure air purifier:
- Power Off: Before beginning, ensure your air purifier is turned off and unplugged from the power outlet.
- Access Filter Compartment: Refer to your Therapure air purifier's original manual for instructions on how to open the filter compartment. This usually involves removing a front or back panel.
- Remove Old Filters: Carefully remove the old, used filters from the air purifier. Dispose of them according to local regulations.
- Unpack New Filters: Remove the new Filter-Monster HEPA filters from their protective packaging.
- Insert New Filters: Insert the new filters into the air purifier. Ensure the foam gasket seal on the filter aligns correctly to create an airtight seal. This seal is crucial for high-performance filtration, directing air through the filter and preventing air from bypassing the filter media.
- Close Compartment: Securely close the filter compartment panel.
- 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 light, consult your air purifier's manual on how to reset it after installing new filters.

Operating Guidelines
Once installed, your Filter-Monster HEPA filters will work seamlessly with your Therapure air purifier to clean the air. For optimal performance:
- Ensure the air purifier is placed in an open area, away from walls or furniture that might obstruct airflow.
- Run the air purifier continuously for best results, especially in areas with high levels of pollutants or allergens.
- The true HEPA filtration system effectively captures microscopic particles, improving overall air quality.

Maintenance
Regular maintenance of your air purifier and timely filter replacement are essential for maintaining air quality and extending the life of your unit.
Filter Replacement Frequency
The lifespan of your HEPA filters depends on various factors, including air quality, usage frequency, and the presence of pets or smokers. As a general guideline, it is recommended to replace your Filter-Monster HEPA filters every 6 to 12 months. Your air purifier's filter indicator light (if equipped) will also signal when a replacement is due.
Cleaning the Filters
The HEPA filters are not washable and should not be cleaned with water or harsh chemicals. Attempting to wash the HEPA filter can damage the filter media and reduce its effectiveness. For the pre-filter (if separate and washable in your Therapure model), refer to your air purifier's manual for cleaning instructions. The pleated design of the HEPA filter is optimized for capturing fine particles.
