Indoor plants give virtually nothing in terms of scrubbing co2. An average human breathes out around 1kg co2 per day. The plants would need to take up 1-2kg in mass to have a measurable effect. That would require a small rainforest at home. If I remember correctly, there were some studies that calculated you'd need to convert half of your room into a dense jungle to offset your own co2. Also, plants release co2 at night, so even if they had any effect, it would be a bad idea to have them in bedroom to scrub air.
