This is usually done with a filter device that captures these particles as the air moves through it, or is used as part of the air system of the whole home.

Choosing the best is the question of deciding which one will do what you need, in a way that works for your situation by comparing the efficiency and usability of different filters.
One of the concerns when buying an air filter is the amount of noise it makes during normal operation.
