Using HEPA air filters and opening windows can remove most indoor microplastics from the air.

“also you can have a HEPA filter as you vacuum that will also capture microplastics”

“Indoor air filter (see above)/ Open windows as much as possible. HEPA air filters should remove most indoor microplastics.”

“Install a HEPA filter at home”

“first and foremost let's consider our indoor environments this is where we spend the majority of our time one effective strategy is to use a HEPA filter this is a high efficiency particulate air filter using these in our homes can be highly efficient at trapping Airborne microplastic particles they can capture particles as small as zero 0.3 microns making them pretty suitable for removing the vast majority of microplastics found in indoor air many of which range from 10 to 100 microns in size”

“many modern vacuum cleaners actually now come equipped with a HEPA filter so this feature allows them to trap microplastics effectively when they're cleaning floors or carpets and it prevents these particles from being redistributed back into the air so regular vacuuming with HEPA filters can also make a substantial difference in indoor air quality as well”
