The first step in any the carpet cleaning process is the pre-vacuuming
stage. In this step the dry soil that comprises the vast
majority of the soils in your carpet is removed.
It has been demonstrated that 74-79% of soil present in carpet is of a
dry nature. If this soil is not removed before adding
moisture, it will literally turn to mud.
We use Tennant industrial vacuums with hospital grade HEPA
filters. HEPA filters, according to the standard adopted by
most industries, remove at least 99.97% of airborne particles that are
0.3 micrometers (µm) in diameter.
These particles are so small in fact that a pin head is 7,000 times
larger than a particle that is 0.3 micrometers (µm) in
This is incredibly beneficial for asthma and allergy sufferers, because
the HEPA filter traps the fine particles (such as pollen and dust mite
faeces) which trigger allergy and asthma symptoms.
All Tennant vacuums are approved by the National Asthma Council of
Australia's (NACA), 'Sensitive Choice' program as products that reduce
the triggers of asthma and allergies.
If your current carpet cleaning contractor does not pre-vacuum, then
they are not providing you with this valuable and important service.
