Lilyturf
This popular ground cover has grassy leaves that are spiked, and it produces blue or white flowers. Although it is usually grown outdoors, it does very well as a window sill plant and since it helps remove trichloroethylene (in printer ink and dry cleaning chemicals), xylene (permanent markers, colouring pens, print cartridges) and ammonia (common aerosols), you may want to line your office or home office windows with pots of lilyturf.
Broadleaf lady palm
You’ve probably seen this in shopping malls, offices and hotel lobbies because they tolerate low levels of light. With a maximum height of around 1.8 metres, they are perfect as a stately and dramatic feature for the low sunlight corners of your home. They do need regular watering and moist soil, but you’ll benefit from the plant’s ability to cleanse the air of formaldehyde, ammonia, xylene and toluene.
Gerbera
These colourful and cheerful daisies were mainly outdoor plants until florists started using them in arrangements. Grown indoors, they can produce flowers at any time of the year, in white, red, orange, pink and purple. The flowers usually last around four to six weeks, but even without the flowers, the gerbera or Barberton daisy has lush, dark green leaves that are effective at filtering out formaldehyde, benzene, and trichloroethylene. They are most happy with full sun and plenty of water and well-drained soil.
