Heart leaf philodendron (Philodendron oxycardium)

This climbing vine plant isn’t a good option if you have kids or pets — it's toxic when eaten, but it's a workhorse for removing all kinds of VOCs. Philodendrons are particularly good at battling formaldehyde from sources like particleboard.

Heart leaf philodendron are very low-maintenance plants. They thrive with indirect light and very little maintenance, according to the University of Florida. The trailing vines can just fall from the container or can be trained to climb up a screen, trellis or pole.
