NASA TOP 30 Plants That Purify The Air

NASA TOP 30 Plants that purify the air

This guide will teach you what the best plants for purifying the air are.  We have reviewed the NASA Study and took their recommended list of 30 plants. Then we researched the ideal growing conditions for each plant.

 Houseplants can offer an all-natural solution to purifying indoor air. Certain plants are better than others at filtering out pollutants and toxic chemicals from the air.  This guide will teach you what the best plants for purifying the air are.  NASA found that the bigger and leafier the plant the better.  "The increased surface area of the leaves seems to increase the amount of air the plant can clean. The amount of leaf surface area influences the rate of air purification.”  The study found that the bigger the leaves the more air the plant could clean.
