A Swedish company called Blueair is selling its air-purification products with the slogan, “breathe plastic-free air”. According to a study published in the journal Environmental Pollution humans inhale significant amounts of microplastics daily, including those which waft from nearby textiles such as polyester bags, carpets, and sweatshirts among other sources. Microplastics are characterized as plastic particles less than five millimeters, which Blueair claims are captured by their filtration systems alongside other more well-known pollutants.
