To know if an air purifier works, check for steady airflow with a light paper, observe visibly clearer air and reduced dust/odors, see filter discoloration (proof it's working), and note if smart indicators drop (like air quality numbers) or allergy symptoms lessen. The most direct way is measuring particles with a dedicated air quality monitor before and after running it.
