Filter characterizations of paralindelöf and meta-Lindelöf spaces are produced. The characterizations are then used to give new proofs of some well-known properties of these spaces. For product spaces, it is also shown that if X and Y are paracompact (respectively, metacompact, paralindelöf, metaLindelöf) then X×Y is paracompact (respectively, metacompact, paralindelöf, meta-Lindelöf), provided that the projection p : X × Y → Y is closed. To Dr. Shashi Prabha Arya. AMS Subject Classification: 54D18, 54C10
