Abrange os filtros anteriormente classificados como filtros grossos (classe G), filtros m\u00e9dios (classe M) e filtros finos (classe F), e elimina as insufici\u00eancias da norma anterior. Com esta altera\u00e7\u00e3o da norma, os utilizadores de filtros poder\u00e3o escolher o filtro com muito maior precis\u00e3o, de acordo com as suas necessidades. Para a avalia\u00e7\u00e3o da efici\u00eancia, a ISO 16890 considera o tamanho de part\u00edcula (mat\u00e9ria particulada = PM) entre 0,3\u00a0\u00b5m e 10\u00a0\u00b5m.
