Although thousands of types of filters work functionally and efficiently, cleaning up filter housings and processing collected dust is a dirty and messy burden in all applications such as vacuum cleaner, dust collector, air cleaner, HVAC, air intake, waste water treatment etc. Dust exposure and dirt contacting are dangerousally for people suffering from allergy and asthma, or public service persons fight in fields of chemistry leak, biochemistry pollution, crime scenes, sanitary area etc.

Typical designs of flat filter panels and cylindrical cartridges can’t contain collected dust and dirt, dust fall on floor or the bottom of the housing. Popular bag filters do capture most of dust inside, but fine particles penetrate through the porous bag wall and contaminate the bag outside. All current filters and apparatuses open many contacting and contaminating paths. Because most of filtration materials are opaque, it prevents visual inspection of dust accumulation that caused clog and lower efficiency. Current concept of filter design is impotent in two major defects of dust exposure and invisible dirt accumulation.

Containing, isolating, and disposing of filtered dust and dirt safely are challenging factors for avoiding second contamination. Naturally porosity of filtration material is impossible for isolation purpose, but widely used plastic films are excellent for isolating dust and dirt inside.

Our revolutionary structure of transparent filter bag combines filter material and package material to form a functional hollow bag, includes an outer transparent plastic film pocket and an inner filter cone, two parts are adhered together on bottom edges, the section view of cavity is “W” profile. All dirt is trapped in cavity between the inner filter cone and the outer plastic film. The plastic film isolates collected dust inside of the bag filter and allow see through dust accumulation. The inner filter cone not only acts as 1st stage filter in where most of dust and dirt are trapped, but also restricts dirty air path just around 2nd stage filter in shortest. A transparent container equipped with a 2nd stage filter is designed to support the transparent filter bag for most reliable and efficiency. It is easy to check dust accumulation in the transparent filter bag, just pull out a fulfilled bag and replace a new clear filter bag without contacting contaminated filters. The old ideas of having a clear plastic strip on paper filter failed because stress concentration and wrong design concept.

This new arrangement carry out excellent features of current filtration and package material, overcome ignored dust cleaning up problem in simplest way. This new concept of disposable transparent bag filter can be used widely in most low temperature air & water filter applications and can extend 2nd stage filter life in low maintenance fashion. It will make dirt processing clear, clean, and simple.
