The vacuum cleaner paper bag is a double-layer bag made from two different materials. The inner lining attracts dust particles, and as air passes through the outer fiber layer, the bag efficiently captures and holds visible dust for easy disposal.
Second-layer filtration: primary filter cotton cloth
The oversized, fine-fiber main filter for electrostatic treatment can filter out... 4 μm Dust particles of various sizes reach 99.5% The extra-large design provides better surface filtration performance. There is also another type... Dralon Material's Gore-Tex The filter cotton can resist acids (filtration up to... 99.995% Greater than 0.33 μm of dust).
Third-layer filtration: Motor protective cover *
The standard motor protective cover is made from a non-woven material composed of wool and synthetic fibers, which can filter out... 2 μm Dust particles of various sizes reach 99.5% This fine filter is ideally suited for installation at the bottom of the motor. In addition to protecting the motor, it can also filter out dust particles as small as bacteria and reduce... HEPA or ULPA Being contaminated and shortening its lifespan.
Fourth-level filtration: HEPA or ULPA filter*

HEPA (The high-efficiency filter) is the final stage of filtration. It is made from glass fiber paper and can remove: 0.3 μm dust reaches 99.97% , which is the diameter of human hair. 1/300 dust particles. Each filter has been processed DOP Testing by (U.S. Army Headquarters) and use according to the appropriate specifications. HEPA The filter can collect toxic and hazardous dust. It is suitable for use in finer filtration applications. ULPA (Ultra-high-efficiency filters) are also made from glass fiber paper, but their material is arranged more densely. They can filter out... 99.9995% dust, including 0.12 μm The size of the dust particles is equal to the diameter of human hair. 1/960 。 ULPA Filter ratio HEPA Filters are more suitable for use in critically important pollution control applications.

Cleanroom Class 1: Install additionally GORE-TEX Filter cloth (resistant to acids, alkalis, and high-temperature dust) ULPA Ultra-high-efficiency filter.
Cleanroom Class 10: Install additionally ULPA Ultra-high-efficiency filter filtration performance ( 0.12 μm Reach 99.9995% ).
Cleanroom Class 100: Install additionally HEPA High-efficiency filter filtration performance ( 0.3 μm Reach 99.97% ).

Cleanroom Class 100,000: Install a particulate matter exhaust filter (referring to the general case) GM80 ) Filtration effect ( 0.6 μm Reach 99.5% ). When installing a fume hood: it can save... HEPA Filters and ULPA By using a filter to directly exhaust waste gases outside the cleanroom, the cleanroom remains free from contamination.

1. Lightweight and capable of handling rough and heavy-duty cleaning tasks.
2. HEPA filters—or even higher-grade ULPA filters—can be selected for cleaning special environments such as cleanrooms and laboratories.
3. The main filter mesh, with an area of 2,100 square centimeters, maintains consistent and stable performance—such as air flow and vacuum level—even after prolonged use.
4. The sturdy lead-based body shell is also durable.
5. When used in a Class 1 cleanroom, equip with a GORE-TEX filter cloth (compatible with high-temperature dust) and an ULPA ultra-high-efficiency filter.
