Three-stage filtration for cleaner air
The trio starts with a Nylon pre-filter to trap hair, lint, and pet fur, reducing surface loading on the main filter. The H13 True HEPA core captures 99.97% of particles 0.3 microns in size, including pollen and smoke particles. The high‑efficiency activated carbon layer, designed with a honeycomb structure, quickly absorbs odors from cooking and pets to improve overall air quality.
