3. Operating Principles
These replacement filters function by trapping microscopic particles, allergens, dust, and other airborne contaminants as air passes through the air purifier. The pleated design maximizes the surface area for filtration, enhancing efficiency.
Once installed, the filter works continuously with your air purifier's fan system to circulate and clean the air in your environment. No direct user operation is required for the filter itself; its function is integrated into the air purifier's normal operation.

4. Maintenance and Replacement
The lifespan of your air purifier filter depends on usage frequency, air quality, and environmental factors. For optimal performance and air quality, it is recommended to replace the filter regularly.
4.1. Filter Lifespan
- Under normal operating conditions, filters typically last between 6 to 12 months.
- If your air purifier has a filter indicator light, replace the filter when the light illuminates.
- In environments with high levels of dust, pet dander, or pollutants, more frequent replacement may be necessary.
4.2. Cleaning
These filters are designed for replacement and are generally not washable or reusable. Attempting to clean them may damage the filter media and reduce filtration efficiency.
