source?

  Don't need a source, it's simple math. For a plant to absorb 1KG of CO2, it needs to increase in weight by at least ~1Kg. An average human exhales ~1KG of CO2 a day. Unless your house plants are gaining half a ton of mass a year, they aren't meaningfully offsetting your CO2 exhilation.

    I’m still with you and your point remains, but the plants do release O2 and just retain the C if I recall. Your plants only need to weigh 27% of that at the end of the year, or about 100kg :D

      Unless your plants are made out of pure diamond, they also need to gain hydrogen, oxygen, and nitrogen in weight. But you are part-right, carbon is ~35-50% of a normal plant's weight.

  Why ask something that's trivial to google yourself? There are numerous good ones, it's a well-known and noncontroversial topic.
