Features:1. Atomstack maker D2 air purifier replacement element, a 3-layer filter element specially developed for laser cutting, which can effectively filter the odor and harmful substances generated by laser cutting, with a filtration rate of 99.5% (atomstack laboratory test data).2. Contribute to environmental protection: Discharging the cutting waste gas directly into the atmosphere will cause more pollution, so use an air purifier to make the air fresh;3. Easy to replace: just three steps, no need to disassemble the circuit, and quickly replace the filter element in five minutes;Filter Material:1 layer (half layer): Modified non-wovens for initial filtration2 layers: Composite electrostatic filter cotton for medium effective filtration3-4 layers: Double-layer composite filter cotton for high and super effective filtration5 layers: High-iodine activated carbon for extended adsorbent6 layers: Composite activated carbon for high effective adsorbentPacking List:1* Atomstack Replaceable Filter for D2 Air Purifier
