There’s no doubt that houseplants can help purify the air around you, but evidence of concrete health benefits is hard to measure. Plants naturally remove toxic compounds from the air, and can keep toxins in a room far below recommended levels. Some researchers also believe that adding indoor plants to a home or workspace can result in an improved mood and also reduce stress levels. So by all means, enjoy as many houseplants as you want. Choose your plants wisely though if you have pets – some can be harmful if consumed.
