Keep your Mi Handheld Vacuum Cleaner 1C running at peak performance with this genuine HEPA filter replacement pack, containing two filters made from highly densified filtering material. Each filter delivers H12 filtering performance, capturing at least 99.95% of particles between 0.1 and 0.3 microns to keep the air around you clean while you vacuum. The filters are fully washable and reusable — simply rinse and let dry before reinstalling — making them a budget-friendly way to extend the life of your vacuum. For best suction performance, Xiaomi recommends replacing the filters every one to two years.
