When it comes to air quality, we often worry about pollution outside. But the air we breathe indoors can also be a concern.

Items such as cleaning supplies, paint and various types of furniture often put off volatile organic compounds (VOCs). These compounds can cause everything from headaches and fatigue to organ damage and possibly cancer.

“Fortunately,” notes Costco.com, “the humble houseplant can significantly reduce concentrations of VOCs. Research shows that it isn’t just the plants that capture these invisible threats – organisms in potting soil absorb them and break them down.”

If you’re looking for plants that can help purify the air, Costco.com recommends the following, low-maintenance options:

• Lady palm
• English ivy
• Ficus
• Rubber plant
• Dwarf date palm
• Peace lily

Costco.com also suggests other actions to ensure safe air, including using the bathroom exhaust fan to eliminate moisture (which can contribute to mold); using non-aerosol, nontoxic cleaning products; checking to see that your furnace and water heater aren’t leaking carbon monoxide; and keeping the chimney flue open when using your fireplace.
