The length and diameter of the vacuum hose will influence the performance, as will the filter’s quality and quantity, which includes the HEPA material’s square footage used to make the filters. As compared to a vacuum with multiple filters, a vacuum with a single filter regardless of how big, will not be able to handle the pulse off dust particles or airflow.
The filter should fit the base strongly; if it gets separated from the base, it will necessitate the entire vacuum to be dismantled to clean the contamination and remove dust. Filters from other competitors have had anecdotal evidence of pulling apart from their bases. When this problem occurs, it will take a considerable amount of valuable working hours to take apart, clean, and assemble the vacuum again, not to mention the added task of cleaning the job site, if required. The depth of the filter pleats should be increased to create a larger surface area to filter the dust entering the vacuum chamber. This type of system allows for the proper discharge of coarse debris during every cycle. A larger quantity of pleats may appear ideal, but in reality, marrow pleats have proven to cause debris and dust to over-accumulate the filter as a result of the smaller area. The floor removing or tile removing process produces coarse debris during the stone, thinset, and tile removal, thus the design of the filter must allow for an increased capacity of dust removal without resulting in CFM loss. You can make a comparison between the 0.1140-inch pleats we offer and other competitor filters which are a meager 0.0670 inches, our filters are 70%+ greater.
