Filters against pollutants in the air

Considering the dangers of air pollution, it is necessary to protect oneself. However, the effectiveness of masks is questioned again and again, as particulate matter has a diameter of 2.5 to 10µm, is smaller than a hair and can flow through the mask. Is there a safer alternative? A company develops disposable filters that are inserted directly into the nose. The advantage is that they do not reduce the amount of air entering the nostrils while effectively filtering ultra-fine dust. The disadvantage remains the price: more than 6€ per filter!
