‘High efficiency’ vacuum cleaners no better at protecting against dust mites

14.02.2006


Researchers at the North West Lung Centre, run by The University of Manchester and based at Wythenshawe Hospital, have discovered that vacuum cleaners with ‘high-efficiency particulate air’ or HEPA filters are no more effective than standard models at reducing exposure to dust-mites.



The team compared nasal air samples taken before and during vacuum cleaning using both HEPA and non-HEPA vacuum cleaners. They found a small increase in exposure to dust-mite during vacuuming with either type of machine, which was increased when emptying the dust compartments of either.

Lead investigator Dr Robin Gore said: “These vacuum cleaners are marketed to allergy-sufferers on the basis that they reduce a person’s exposure to air-borne particles raised from carpeted floors. For allergy sufferers, such particles can trigger asthma attacks. However, we have already found that both HEPA- and non-HEPA vacuum cleaners can actually increase an individual’s exposure to particles containing cat allergens.


“These latest findings further suggest that there is no significant advantage to using a HEPA vacuum cleaner to reduce exposure to air-borne particles like dust-mites.

“In combination with our previous work, the study seems to confirm that high-efficiency vacuum cleaners confer no benefits and should not currently be specifically recommended to allergy sufferers as a means of reducing personal exposure to allergens, either by their manufacturers or health professionals.”

The study was published in the January 2006 issue of the European Journal of Allergy and Clinical Immunology. The co-investigators in the study were Professors Ashley Woodcock and Adnan Custovic.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
