Indoor plants are capable of improving the oxygenation in the room and removing some pollutants from the air. But Carver warns that added greenery won’t make a substantial difference to the air quality in a room unless it’s “filled with plants”. This doesn’t mean that someone shouldn’t add greenery to their space. Carver says it's important to do one’s research on the plants, because some collect more dust or require moist potting soil, which can lead to mold. “You can also focus on greening the outdoor environment just outside your home,” Carver says. Some top allergy friendly plants include the bamboo palm and the dracaena, both of which can help purify the air and capture some allergens.
