GENUINE PERFORMANCE & COMPATIBILITY This official Jafanda replacement filter ensures peak performance and compatibility for your JF239 air purifier. The 3-stage filtration system with a pre-filter, True HEPA filter, and activated carbon filter effectively removes pollutants and maintains optimal air quality. TRUE HEPA FILTRATION The True HEPA filter captures 99.97% of airborne particles at 0.3 microns, and down to as small as 0.015 microns, including dust, pollen, pet dander, and more. This helps reduce allergy symptoms like sneezing, itching, and congestion, promoting better breathing and healthier air. POWERFUL ODOR ELIMINATION WITH ACTIVATED CARBON Our unique activated carbon filter utilizes a catalytic process for superior odor absorption. It effectively removes common household odors like cooking smells, pet dander, smoke, and VOCs, leaving your home feeling fresh and clean. EXTENDED FILTER LIFE WITH PRE-FILTER The pre-filter traps large particles like dust, lint, and pet fur, maximizing the lifespan of your True HEPA filter. It's also easy to clean with a soft brush or vacuum cleaner. Genuine Jafanda Filter & Replacement Reminder: Remove the plastic packaging before use. Replace your filter when the JF239 Air Purifier Filter Light turns red (typically after 4-6 months of use) to maintain optimal performance.
