1. Designed for Laser Filtration: The AtomStack D4 air purifier features a 3-layer filter design, achieving a purification efficiency of up to 99.97%. 2. Brushless Motor for Quiet Operation: The power system uses a single-phase brushless motor for strong suction and quiet operation, with noise levels ≤68DB. 3. Adjustable Speed: The electrical system incorporates our specially designed advanced modular circuit board, allowing for multi-level speed adjustments. 4. Long Lifespan: A single filter cartridge (when replacing the initial and medium-efficiency filters) can continuously work for approximately 40 hours during normal laser cutting of wood, providing long-term effective protection. 5. Easy to Replace: The filter can be changed quickly within five minutes without disassembling any circuits, in just three steps.
