PM10. The dirt you can’t see: collect fine dust

Types of dirt, Sweepers, Accessories

Different types of dirt can be observed with the naked eye. Sometimes it may seem that you have obtained a perfectly clean environment by collecting a piece of paper or washing a floor with oil stains. But what if certain types of dirt were not seen and were harmful to health?

Dust travels in the air and is breathed. It lies on the ground, on the machinery and moves in the environment. The quality of cleaning also depends on the ability to collect dust, even the thinnest. The quality of the air in the work environment is of primary importance, so much so that there is an ISO classification that makes it possible to identify the type of powder, the one understood as particulate matter, or fine dust.


The classification of fine dust: PM


The PM (Particulate Matter) is the value that indicates the diameter of the particulate measured in microns. PM1 indicates all the particles lower than the micron, with PM2.5 those lower than 2.5 microns and finally with PM10 the particles lower than 10 microns. This definition is given based on the ISO 16890-2016 classification.

In closed environments the external atmospheric air enters, through windows and doors or other types of ventilation, even the one that allows to cool or heat the air.
But how is it possible to get good air quality? Beyond the filters of the ventilation system whose primary control and maintenance, it is necessary to deal with a cleaning that is really efficient to capture also the particulates.


PM10 is made up of smoke, dust and aerosols (a technicality to indicate liquid microdrops). In the workplace, often, there are pm10 particles, commonly called soot, dust, haze, fog. The fine dust called PM10 are present above all in environments where combustion processes take place, for example where there are heating systems, in the presence of ignition engines, thermal power stations, incinerators, in environments where biomass combustion is carried out …

PM10 particles have been studied in recent years, to try to determine the impact that these particles have on human health. Although, according to the 2005 WHO guidelines, it is hypothesized that reducing PM10 particles from 70 to 20 micrograms per cubic meter could reduce mortality rates in polluted cities by up to 15% each year.

Reduce PM10 in the workplace

Although there are no reliable data and the impact of PM10 is still being analyzed, it becomes important to preserve the health of workers by keeping work environments clean. Floor cleaning plays a role in contrasting PM10 because the dust suspended in the air then falls to the ground from where the trampling lifts them up again and makes them reach the respiratory tract, creating damage and ills for those who work in that environment.

To successfully collect them from the ground you need a sweeper with

  • a large filtering surface
  • special filter.

Just as the RCM REAR LOAD sweepers have always been, allowing you to mount FILTERS OF LARGE SIZE without compromising visibility to the operator.

Moreover, the special KERASTATIC FILTER retains PM10 and electrostatic dust.

Specifically designed to be more efficient, the RCM filter collects more dust (thanks to its significantly larger size than competitive filters) and is able to take even the finest dust, such as PM10. In this way, the use of an RCM machine makes the environment treated healthier and significantly reduces those particles that are invisible to the human eye.
