Setup and Installation

Follow these general steps to replace your air purifier filters. Always refer to your specific A-len Breathe A350 or A375 air purifier manual for detailed instructions and safety precautions.

Power Off: Ensure your air purifier is turned off and unplugged from the power outlet before beginning any filter replacement.
Access Filter Compartment: Open the filter compartment cover on your A-len Breathe air purifier. The location may vary, so consult your air purifier's manual.
Remove Old Filters: Carefully remove the used HEPA filter and any old pre-filters. Dispose of them according to local regulations.
Install New Pre-Filter: Place a new pre-filter onto the main True HEPA filter. The pre-filter is designed to attach with Velcro strips for easy replacement.
Install New HEPA Filter: Insert the new True HEPA filter (with the pre-filter attached) into the air purifier's filter slot. Ensure it is seated correctly and securely. The polyurethane foam seal around the HEPA filter ensures a tight fit, preventing unfiltered air from leaking.
Close Compartment: Close the filter compartment cover securely.
Power On: Plug in and turn on your air purifier. Reset the filter indicator light if your model has one, following your air purifier's instructions.

Operating

Once installed, the Nispira BF25A BF15A filter set operates continuously with your A-len Breathe air purifier to clean the air. The air purifier draws in air, which passes through the pre-filter, then the True HEPA filter, and finally the activated carbon filter before being released as purified air.

For optimal performance, ensure the air purifier is placed in an area with good air circulation and away from obstructions.

Maintenance

Regular maintenance of your air filters is crucial for maintaining air purifier efficiency and air quality.

Pre-Filter Replacement: The pre-filters are designed for frequent changes. It is recommended to replace the pre-filter every 2-4 weeks, or more often depending on air quality and usage. This helps prolong the life of the main HEPA filter.
True HEPA Filter Replacement: The main True HEPA filter typically lasts up to 6-8 months under normal operating conditions. Replace it when the filter indicator light on your air purifier illuminates, or if you notice a decrease in air quality or airflow.
Visual Inspection: Periodically inspect both the pre-filter and HEPA filter for visible dirt and debris. If they appear heavily soiled, replace them even if the recommended time frame has not passed.

Troubleshooting

If you experience issues after installing your new filters, consider the following:

Reduced Airflow: Ensure the filters are installed correctly and seated firmly in the compartment. Check for any obstructions around the air purifier's intake or output vents.
Persistent Odors: Verify that the activated carbon pre-filter is correctly installed. If odors persist, it may be time to replace the pre-filter or the main HEPA filter if it's nearing the end of its lifespan.
Filter Indicator Light: If the filter indicator light remains on after replacement, consult your air purifier's manual for instructions on how to reset it.
Unusual Noises: Ensure all filters are properly seated and the compartment cover is closed securely. Loose filters can cause rattling.

For further troubleshooting, refer to your A-len Breathe air purifier's user manual or contact Nispira customer support.
