Powerful Purification Efficient filtration The honeycomb filter is covered with a layer of meltblown fabric to reinforce the density of the filter, which can filter out small particles and strongly adsorb volatile organic compounds. The importance of timely replacement of filter cartridges Printers generate volatile organic compounds during printing, as materials such as ABS, PC, and PA have higher heating temperatures, resulting in a higher concentration of volatile organic compounds. Materials such as PLA with lower melting points produce less volatile organic compounds during the printing process. These volatile organic compounds are absorbed by our activated carbon air filters. fit For H2D Item Type:Hardware Parts / Machine Parts Color: Black Material: Plastic + Activated Carbon Package Contents: 1 x Air Purifier Filter Only the above package content, other products are not included.
