Which house plants emit the most oxygen into the air?

You can find info on the web.....but a good general rule is the faster growing the plant the more O2 it puts out. You can get into the technical stuff, but that's what it all comes down to.

Which house plants emit the most oxygen into the air?
All house plants do. The more you water them the more they grow the more oxygen they will produce. I have a lot of vine plants all over my place and they produce a lot of oxygen..
Reply:In general, a larger or faster-growing houseplant will produce more oxygen than a smaller or slower growing one. Also, with two identical houseplants, the one receiving more light will likely produce more oxygen assuming the plants receive adequate levels of water, mineral nutrients and temperature. Houseplant growth is often limited by low light. Also remember that plants use oxygen gas and give off carbon dioxide gas in the dark when there is no photosynthesis.
