Soil removal efficiency is the most important measure of a vacuum’s performance. Thorough cleaning and disinfection can only be successful if all the dirt is removed first.

The type of filtration system used is largely dependent upon the environment you wish to clean. In industrial plants, ULPA filtration is often specified, while HEPA filtration is typically sufficient for institutional and commercial facilities. To be considered certified HEPA, a filter must be individually tested and verified. HEPA filters that have gone through this process are known as true HEPA.

There are also many filters on the market labeled HEPA-type, HEPA-like, or something similar – these filters have not been individually tested or verified, so their efficiency can’t be guaranteed. We recommend that you look for filters labelled H13, H14 or U15.

Vacuums come in bagged and bagless varieties. A vacuum with a dust bag will help ensure the particles you collect are retained. With a bagless vacuum, there is more of a risk that the particles will be re-released into the air while emptying.

Edge cleaning is important for complete coverage. Ineffective vacuums and improper end tools will not only make it difficult for the disinfectant to do its job, but also leave a gray, dusty edge along your walls.

Special safety vacuum cleaners (dust extractors) for the Building & Construction and Industrial industries for handling hazardous dust are divided into three classes of use: Class L for moderate-risk dust, Class M for medium-risk dust, and Class H for high-risk dust. If your environment contains hazardous dust, make sure to choose a vacuum rated for the appropriate dust class.

Vacuums come in a lot of shapes and sizes – upright, backpack, canister, etc. Each is designed for a specific task, so make sure to select equipment that matches your application.
