Hi, Lex-ers,
Jill, the botanist, here.
Bob Primak's reply sums up most but not all of the advantages of house
plants.
As far as O_2 /CO_2 the plants don't add much O_2 because at night, when
there is no light, they use O_2 and create CO_2 .
The primary air advantage they provide is in removing certain air
pollution components - particularly formaldehyde, which is emitted from
new carpets, furniture and plywood, among other sources. Some plants are
better than others at this. There is a list of 10 best as determined by
NASA in the second link below.
