Snake plant (Sansevieria trifasciata 'Laurentii')
Also known as mother-in-law’s tongue, this plant is one of the best for filtering out formaldehyde, which is common in cleaning products, toilet paper, tissues and personal care products. Put one in your bathroom — it’ll thrive with low light and steamy humid conditions while helping filter out air pollutants.
You may also want to put a couple of these sharp-leafed plants in your bedroom, suggests This Old House. Interestingly, they absorb carbon dioxide and release oxygen at night (the opposite of the timing process most plants follow). Sharing your room with these plants could give you a slight oxygen boost while you sleep.
