One of the very best ways of creating an indoor airborne health hazard is to suck all the bacteria, fungal spores, dust mite faecal particles, and any other particulate allergens out of the floor covering, and then blow them liberally into the surrounding air, where they travel easily from room to room contaminating the whole building.
IEC60312 is the only international standard available for the measurement of air filtration efficiency of vacuum cleaners for household and similar use.
The test is performed with the complete vacuum cleaner mounted inside a sealed test rig specified by the standard. The cleaner inlet is dosed with measured amounts of standard dust, and particles in the discharge air are counted into six separate size bands down to 0.3 microns. The test approximates to actual use conditions and the results are standardised as a single percentage efficiency figure, enabling the direct comparison of one vacuum cleaner with another.
To meet the ‘HEPA’ standard of filtration the unit must remove particles larger than 0.3 Microns in diameter with more than 99.97% efficiency (i.e., fewer than 300 particles per million of 0.3 Micron size should penetrate).
The Victor V9 HEPA 9 litre tub vacuum, in tests, achieves an efficiency of 99.9965% - passing only 35 particles per million which is 8 times better than the standard allows.
Powerful suction and proven effective filtration make the Victor V-9 one of the most productive tub vacuum cleaners available.
