Here's a link to a list of plants that are most effective at cleaning indoor air quality.
NOTE: at the very very bottom of the list is a footnote that says "Some of these plants may be toxic for your pets, so please do your research to ensure your furry friends stay safe."
Be sure to locate your plants wisely.
