How well does your vacuum filter? when you use it at home
Filtration should be measured by overall dust capture from all possible escape points (filters, body seams, vacuum tools, point of contact with the surface) rather than just the actual filter media.
Uprights have one unique point of vulnerability: the interface between the beater brush opening and the floor covering. When the floor covering is “beaten” or agitated, dust can become airborne if the airflow, lift and air speed does not remove it. The wide orifice that accommodates the beater brush can lower air velocity and cleaning ability if the ratio of airflow factors to orifice-width is not optimal.
Does the vacuum have HEPA media? Great. Microfilter media? This can work equally well in non-cleanroom applications. Remember, the entire system needs to be considered to determine overall dust capture, not just the type of filters. Similarly, are airflow and suction balanced to enable the filters to trap the dust without blowing it through the media?
How are the body integrity and seals? Is the machine engineered using close tolerances and good seals to prevent dust from escaping where it shouldn’t? Testing is important. Has the manufacturer used a credible third-party testing lab to measure dust capture efficiency at the vacuum’s airflow rate? Has the vacuum also been tested in a chamber to determine overall emissions from the entire machine, not just the filters?
