Excellent sealing design: The dust bag features a strong sealing design that effectively reduces the risk of dust leakage, preventing dust from escaping and ensuring that particles sucked into the dust bag do not easily flow back out into the air. High-efficiency filtration: Our dust bags consist of two layers of ultra-fine melt-blown fiber filters and two layers of precision fleece, effectively blocking over 99.9% of dust, 0.3-micron particles, and other debris. Easy to use: Our dust bags feature an advanced \"push-pull\" handle design, allowing for easy removal and replacement of the entire dust bag without touching the dust, making it simple even for people with dust allergies. Each dust bag has a 3-liter capacity and provides up to 7 weeks of dust storage. (Applicable models must be determined according to this manual, title, and images.)
