Green 'Air-purifiers'


Did you know that some plants can improve the air quality indoors?
“ A few pots of plants will make a marked improvement to the quality of indoor air. They do not just add some greenery, but they also ‘filter the air’. They take in toxins and break them down with the help of microbes in the compost.”
–British landscape and garden designer Andy Sturgeon.
His top picks for these green air-purifiers include the Boston fern, the dumbcane, money plant and the corn palm because“they are easy to grow and do well in an indoor environment”.
