Maintain clean, fresh airflow with this 3-stage replacement filter set compatible with LEVOIT Vital 100 Air Purifier / Replacement for Vital 100-RF part. The set includes 1 HEPA filter with an activated carbon layer plus 2 pre-filters to help keep your purifier performing as intended. The HEPA filter captures 99.97% of airborne particles as small as 0.3 microns, while the activated carbon filter helps absorb household odors from pets, cooking, and smoking, and can help reduce VOCs. The pre-filters trap larger particles such as dust, hair, pet fur, and lint, helping extend overall filtration performance. Designed for simple, tool-free replacement, this filter set is ideal for routine home maintenance in bedrooms, living rooms, nurseries, and offices. For optimum performance, replacing the HEPA filter every 3-6 months is recommended depending on environment and usage frequency.
