Bringing a bit of nature into your home does more than brighten the atmosphere. Introducing houseplants into various rooms in the house can help reduce the chance of getting seasonal sicknesses (such as the common cold), remove airborne contaminants (volatile organic compounds [or VOCs]), reduce the chance of headaches, lift your mood, decrease your blood pressure, reduce allergies, improve sleep and much more. 
The 20 plants listed below are specifically known for their air purifying properties. And while an open window may feel like all the fresh air you need, did you know that everything from toilet paper to common household cleaners can contain chemicals and release toxins like formaldehyde? Or that VOCs like benzene can be released into the air by everything from the paint on your walls, to the printed material found in your home?
So why not breathe a bit easier and enjoy the beauty of a new houseplant at the same time!
Warning for pet owners: some common plants can cause toxicity in pets. Please check this list of common poisonous plants before bringing home a house plant.
