The EN779:2012 standard was replaced by ISO 16890 for several reasons. The efficiency test of the EN779:2012 standard uses a synthetic powder with particle size of 0.4 μm. By loading the filter with this powder in the laboratory, the efficiency of the filter is determined only for particles of 0.4 μm.
In practice, filters are exposed to various types of substances of different sizes, and ISO 16890 provides efficiency at different particle sizes.
Health Effects of Fine Dust
In certain areas, air pollution is increasing, which has direct consequences for health. Studies have shown that fine dust poses a serious health risk. It can cause cancer and respiratory diseases. Air filters create a healthy living environment by significantly reducing the concentration of fine dust.
Fine dust particles larger than 10 μm are captured by the mucous membranes in the nasal cavity and throat and are generally swallowed or coughed up.
Fine dust particles smaller than 10 μm penetrate deeper into the respiratory tract, causing irritation to the airways and reduced lung function.
Fine dust particles with a diameter of 2.5 μm penetrate deeper into the respiratory tract and are retained in the bronchi, posing a real risk to health. These particles can cause pneumonia and possibly even cancer if the dust particles are carcinogenic.
Particles smaller than 1 μm penetrate even deeper into the respiratory tract and are small enough to reach the lungs and alveoli. The cell membranes can become damaged due to inflammation, leading to cell death. This results in reduced lung capacity. People with respiratory conditions such as COPD and asthma are particularly vulnerable, as are young children and the elderly.
