3. Product Features
The Keedal IAF-H-100C filter system is engineered to provide comprehensive air purification:
- H13 True HEPA Filter: This layer is designed to capture 99.97% of airborne particles as small as 0.3 microns. This includes fine dust, pet dander, pollen, and smoke particles.
- Activated Carbon Pre-filter: This pre-filter effectively absorbs common household odors such as pet odors, smoke, cooking smells, and adverse volatile organic compounds (VOCs). It also captures larger particles, which helps to extend the lifespan of the HEPA filter.

4. Installation and Replacement
To ensure optimal performance of your air purifier, follow these general steps for filter replacement. Refer to your specific Idylis air purifier manual for detailed instructions.
- Power Off: Always unplug your air purifier from the power outlet before attempting any maintenance or filter replacement.
- Access Filter Compartment: Locate and open the filter compartment on your Idylis air purifier. This usually involves removing a cover or panel.
- Remove Old Filters: Carefully remove the used HEPA filter and carbon pre-filter. Dispose of them according to local regulations.

5. Maintenance and Replacement Schedule
Regular filter replacement is crucial for maintaining the efficiency of your air purifier and ensuring clean air. Over time, filters accumulate particles and odors, which can reduce their effectiveness and potentially lead to secondary air pollution.
- H13 True HEPA Filter: It is recommended to replace the HEPA filter every 6-12 months.
- Activated Carbon Pre-filter: It is recommended to replace the carbon pre-filter every 3-6 months.
The actual replacement frequency may vary depending on air quality, usage duration, and the presence of pets or smokers in your environment.
