What house plants produce the most oxygen?

Answer 1

I've been looking for this answer. But it is difficult to find. However, If you simply want to place plants in your house you need to look at getting rid of all pollutants, NOT just increasing oxygen levels. These are the top pollutant reducing plants as discovered during a 2 year experiment by NASA. I know it is not what you asked for, but I hope it helps. TOP 10 plants most effective in removing:
Formaldehyde, Benzene, and Carbon Monoxide from the air Bamboo Palm - Chamaedorea Seifritzii Chinese Evergreen - Aglaonema Modestum English Ivy Hedera Helix Gerbera Daisy Gerbera Jamesonii Janet Craig - Dracaena “Janet Craig” Marginata - Dracaena Marginata Mass cane/Corn Plant - Dracaena Massangeana Mother-in-Law’s Tongue Sansevieria Laurentii Pot Mum - Chrysantheium morifolium Peace Lily - Spathiphyllum Warneckii - Dracaena “Warneckii”

Answer 2

One answer:

To survive the plants have to leave oxygen, which is very important for us. But all the trees that grow or grow inside the house provide relatively little oxygen.

More information:

There are various internet articles listing houseplants that are the best oxygen producers and air filters. These articles mention NASA studies, but it is difficult to determine if the article content was actually derived from the studies:

• One plant that makes several lists is Sansevieria aka Snake Plant aka Mother-in-Laws Tongue. The more unusual thing they note is that Sansevieria makes oxygen at night, which would make it a good candidate for bedrooms. It also filters formaldehyde from the air. Some sites note that Mother-in-Laws tongue is a particular variety that has the yellow strips along the leaf margin. I have not found anything to indicate other Sansevieria do or do not have similar oxygen-producing or air-filtering properties.
• Areca Palm is supposed to convert a lot of carbon dioxide to oxygen during the day - in addition being a filter for xylene and toluene.

It is important to understand that to make a significant difference in your indoor air quality, you need several of these plants per person in your household.
