Commercial HEPA Bags & Filters

Can an M-Class vacuum be upgraded to an H-Class by changing the filter?

No, an M-Class vacuum cannot be upgraded to H-Class just by changing the filter. H-Class vacuums meet specific standards and requirements that go beyond the filter’s capabilities. Some M-Class vacuums can be modified to meet H-Class requirements, but this requires testing and certification by qualified personnel.

What Is In A H Class filter

An H-Class filter in industrial vacuums is designed for high-efficiency filtration, capturing 99.995% of particles as small as 0.3 microns. These filters, typically meeting HEPA H14 or H15 standards, are made from a dense mat of fine fibers, often glass or synthetic, to trap hazardous particles like asbestos and lead. The filters are part of a sealed system to prevent dust escape and are not cleanable, requiring replacement once soiled. H-Class filters are often complemented by a primary L/M Class filter to enhance longevity and ensure compliance with strict safety standards like AS60335-2-69 or AS 3544.

Are L-Class vacuum Filters suitable for handling concrete dust?

No, L-Class vacuum filters are not suitable for handling concrete dust, which is a higher-hazard material. L-Class vacuum filters are designed for lighter hazards like gypsum/plaster, some aluminum, and general dust and dirt. For concrete dust, a vacuum filter with a higher classification, such as M-Class or H-Class, would be more appropriate.

What filters do you need for silica dust vacuums?

For handling silica dust, an M-Class vacuum with a HEPA H14 filter is generally suitable, as it effectively filters out 99.95% of particles 0.3 microns in diameter, ideal for medium-hazard materials like construction silica. However, in environments with higher concentrations of fine silica dust, an H-Class vacuum with a HEPA H15 filter is recommended, providing a higher filtration efficiency of 99.995% for the same particle size. The choice depends on the specific hazard level of the silica dust, with H-Class offering the highest protection in more hazardous situations. Both types of vacuums should be fully sealed to prevent dust escape.

What Can I Use L Class Filters For?

L-Class filters, with a filtration efficiency of 99% for particles 0.3 microns in diameter, are suitable for light-hazard materials. They are ideal for general cleaning tasks in environments like libraries, museums, offices, workshops, and warehouses, where they can effectively handle dust such as gypsum, plaster, some types of aluminum, and general dust and dirt. L-Class vacuums, equipped with these filters, are not intended for high-hazard materials like silica or asbestos but are excellent for light construction and general warehouse settings where a high level of air cleanliness is required.
