Introduction
This manual provides instructions for the proper installation and maintenance of the DH Lifelabs 3-in-1 HEPA Replacement Filter, designed for use with DH Lifelabs Aaira + HEPA and Sciaire + HEPA air purifiers. Adhering to these guidelines ensures optimal performance and longevity of your air purification system.
Product Overview
The DH Lifelabs 3-in-1 HEPA Replacement Filter is an integrated filtration system designed to capture various airborne particles and odors. It consists of three distinct layers:
- Pre-Filter: Captures larger airborne particles such as sand, dust, and pet hair.
- HEPA Filter: Captures allergens, pollen, and small airborne particles as small as 0.3 microns.
- Activated Carbon Filter: Absorbs odors, gases, and volatile organic compounds (VOCs).

- DH Lifelabs Aaira + HEPA
- DH Lifelabs Sciaire + HEPA

Setup and Installation
- Power Off: Before beginning, ensure your DH Lifelabs air purifier is turned off and unplugged from the power outlet.
- Access Filter Compartment: Refer to your air purifier's specific user manual for instructions on how to open the filter compartment. This typically involves twisting or unlatching the base or cover.
- Remove Old Filter: Carefully remove the used 3-in-1 HEPA filter from the air purifier. Dispose of the old filter according to local regulations.
- Unpack New Filter: Remove the new DH Lifelabs 3-in-1 HEPA Replacement Filter from its protective packaging.
- Insert New Filter: Place the new filter into the air purifier's filter compartment. Ensure it is seated correctly and securely. The orientation may be indicated on the filter or the purifier itself.
- Close Compartment: Close and secure the filter compartment cover or base.
- Reset Filter Indicator (if applicable): Plug the air purifier back into the power outlet. If your model has a filter replacement indicator light, follow the instructions in your air purifier's manual to reset it. This usually involves pressing and holding a specific button for a few seconds.
Note: Always handle filters by their outer frame to avoid touching the filtration media.
Operating Considerations
Once the new filter is installed, your air purifier is ready for operation. The 3-in-1 filter works continuously to clean the air. No specific operational steps are required for the filter itself beyond proper installation.
Maintenance and Replacement
For optimal air purification performance, it is recommended to replace the DH Lifelabs 3-in-1 HEPA Replacement Filter every 12 months under normal operating conditions. Factors such as air quality, usage frequency, and pet presence may necessitate more frequent replacement.
- Regularly check your air purifier's filter indicator light, if available.
- A noticeable decrease in air purifier performance or an increase in odors may indicate the need for earlier filter replacement.
- Do not attempt to wash or clean the HEPA or Activated Carbon filter layers, as this can damage the filtration media and reduce effectiveness. The pre-filter layer may be gently vacuumed if accessible and recommended by your air purifier's manual, but this filter is designed as a single-unit replacement.
Troubleshooting
If you experience issues after replacing the filter, consider the following:
- Air Purifier Not Turning On: Ensure the filter is correctly seated and the compartment cover is fully closed and secured. Some air purifiers have safety switches that prevent operation if the filter is not installed properly.
- Filter Indicator Light Remains On: If your air purifier has a filter reset function, ensure you have performed the reset procedure as outlined in your air purifier's manual.
- Poor Air Quality After Replacement: Verify that the new filter was removed from all plastic packaging before installation. Ensure the air purifier is operating on an appropriate fan speed for the room size.
