[0002] In industrial production, pigment liquids, photoresists, liquid crystals, food products, etc. are all products with high requirements for cleanliness. During filling, the filling room needs to ensure ultra-high cleanliness of the operating environment to meet product requirements or improve product quality. The particulate filtration and purification device can adsorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odors, decoration pollutants such as formaldehyde, bacteria, allergens, etc.), effectively improve air cleanliness, and can adsorb and filter the particulates in the filling room to improve the cleanliness of the filling room.

[0003] The existing particulate filtration and purification devices usually adsorb and filter the particulates in the air through the filter screen inside the device.
