Large Capacity: The dust bag is specially customized for X10 PRO, using aerospace-grade composite filter material and three-dimensional pleated design to achieve efficient separation of dust and air, and prevent dust from flowing through and contaminating the air duct. The large 4L capacity can easily hold about 60 days of dust and garbage for an average 120m² family, reducing the trouble of frequent replacement and allowing you to enjoy the worry-free experience of "one waste per month". Quadruple antibacterial protection blocks allergens at the source: First layer: silver ion antibacterial coating: kills 99.9% of bacteria on contact, inhibits the growth of dust mites and mold; Second layer: activated carbon adsorption layer: strongly absorbs allergens such as animal hair and pollen, with a 95% odor purification rate; Third layer: high-density melt-blown cloth: filters 0.3μm; its PM2.5 filtration efficiency is comparable to that of N95 masks; Fourth stage: Sealed hot-pressing
