About This
- This AP400 True HEPA filter is designed specifically for the SIESEAN AP400 Air Purifier. Please check your purifier model before placing an order to ensure compatibility.
- This AP400 replacement filter filters out 99.97% of airborne particles as small as 0.3 microns. Effectively reduces dust, smoke, pet dander, pollen, lint, cooking odors, and other pollutants to enhance indoor air quality and promote healthier living.
- The AP400 filter combines layered protection: The HEPA filter filters out fine dust like pollen, smoke, and pet dander, while the activated carbon layer absorbs everyday odors from pets, cooking, and household fumes to maintain fresher indoor air.
- This value pack includes 4 HEPA Filters and 4 Activated Carbon Filters, recommended to change filter once every 4-6 months. You may need to replace your filter earlier or later depending on how often you use your air purifier.
- After installing the new filters, be sure to reset the air purifier: plug it in and press and hold the reset button for 3 seconds. This clears the filter replacement indicator and ensures the unit operates correctly.
