Researchers at a United Kingdom
medical university are claiming 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 researchers at the North West
Lung Centre, run by The University
of Manchester and based at
Wythenshawe Hospital, 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.

it is scratched.
2. Polish if it
lacks gloss.
3. Protect if
staining could
occur.
4. Maintain to
avoid the cost
of the above. |
