As it’s a CAM plant, it also emits oxygen and absorbs carbon dioxide at night, along with benzene, formaldehyde, xylene, and toluene.2. Christmas Cactus

Image source: redditDumb Cane was effective in reducing the CO2 levels from 1,868 to 1,506 ppm within 24 hours, therefore, increasing the oxygen levels. The plant also cleans off VOCs like acetone, benzene, formaldehyde, and toluene inside the home.8. Pothos
Image source: aroidwikiPothos is the number one indoor plant for oxygen due to its fast conversion rate. In an experiment, it was able to show a 6.5% reduction in carbon dioxide, where it decreased the CO2 content from 454PPM to 425PPM, thereby increasing the oxygen levels.9. Spider Plant
Image source: ugaooThough the spider plant is not the most oxygen-producing plant on the list, it earned its place here as it is one of the best plants to reduce stress and increase productivity.10. Weeping Fig
Image source: qdstoresThe weeping fig has been proven successful in lowering the concentration of CO2 in the air according to research by the Pukyong National University, Busan, Korea. Thereby, it bumps up the oxygen levels by a considerable margin. It is also a potent plant to filter out harmful VOCs like formaldehyde, benzene, and trichloroethylene.
