Why do you need a spider plant in your bedroom?

Quite simply, because plants are nature’s air freshener — they continually improve a room’s air quality by increasing the oxygen and removing pollutants. Easy-to-grow spider plants, philodendrons, and golden pothos are the most effective, according to a NASA study. Talk about potluck!

What goes for chili recipes and golf swings also goes for air quality: Little changes can make a big difference. In addition to placing purifying plants around your home, here are some things you can do to go with the air flow:

* In heavy traffic, drive with the windows rolled up and the air on a recycle setting.
* If you use an air purifier or humidifier, change the filter regularly.
* Clear your life of tobacco smoke — secondhand or otherwise.
* Test for radon before buying a house.

One caveat: If you have pollen allergies, you’ll obviously have to use caution when selecting household plants. The same goes for people with allergies to mold or fungi, which often can form in houseplants. Limit yourself to just a few, and check them often for signs of mold or fungus.
