PM2.5, commonly called fine particulate matter or fine dust, are solid and liquid atmospheric particles suspended in ambient air having a diameter of 2.5 micrometers or less. They are dangerous pollutants because they are able to penetrate through our respiratory system reaching deep into the lungs and even into the bloodstream. Monitoring PM2.5 levels is critical to assessing the health risk associated with exposure to fine particles.

PM2.5 concentrations vary throughout the day depending on temperature, humidity and discontinuous emission from individual sources. The main sources are air conditioning/heating systems (e.g., stoves or wood furnaces), vacuum cleaner use, candles, incense, and the presence of pets. PM2.5 can also come from outside as a result of traffic, industrial emissions, wood burning, and agricultural activities. In addition, PM2.5 can increase in conjunction with low humidity (<40%).

It is important to remember that there are many variables in a home that affect the concentration of PM2.5 and the ability to dilute it over time, starting with the layout of spaces and the design of air recirculations.

Natede helps to reduce the level of PM2.5 in the air, however, it is also essential to have other tricks to improve it, such as ventilating the room often if the traffic is not intensive and to reduce if possible the source of pollution, not smoking in or near doors or windows, opening the hood extraction system while cooking (better if without internal air recirculation), preferring wet washing when cleaning.

Remember that proper maintenance of the Natede is essential and necessary to ensure proper PM2.5 readings (be sure to clean the water tank well and occasionally water the plant directly from the potting soil).

The optimum value is less than 12 μg/m3.
