Image via WikipediaAll the major air pollutants (car exhaust, factory fumes, sidewalk smokers) are outside, right? Not so much. Indoor air may be the grimiest stuff our lungs filter each day. Studies show that things like candles, printers, and even shoes can fill your rooms with harmful contaminants, says Ted Myatt, Sc.D., an environmental scientist in Boston. But there's no need to live in a tent in your backyard—just follow these easy steps to lighten the load on your respiratory system.
The Pollutant: Candles
The Solution: Choose cleaner mood lighting in the form of electric votives, or buy 100 percent soy candles, which can burn at a slower rate and emit less soot. If you can't avoid burning paraffin, do so only occasionally and in a draft-free area. And cut out the heavily fragranced jar-style versions, says May; they produce more soot.
The Pollutant: Printers
The Solution: Set up your printer in a well-ventilated area and try to stand at least 10 feet away from it during a lengthy job (good advice for when you're at the office too). And remember to print in black-and-white whenever you can, because color ink produces more noxious debris. To see if your printer is on the high-emitter list, visit the International Laboratory for Air Quality and Health online at www.ilaqh.qut.edu.au.
The Pollutant: Dust
The Solution: Sweep a vacuum with a high-energy particulate airborne (HEPA) filter over your floors once a week, and wipe all other surfaces with a clean, damp cloth (make sure you dampen it with water—many spray cleaners, especially those with added fragrance, contain lung-irritating chemicals). And once a month, run your bedding—pillows, comforters, quilts—through a hot dryer cycle; the high temperature will kill any dust mites.
The Pollutant: Shoe Debris
The Solution: Dislodge clods of dirt or grass by rubbing your shoes over a durable outdoor mat (bristly coconut-husk types work best). Once inside, leave your kicks on a cloth mat by the front door.
The Pollutant: Furniture
The Solution: Ventilate, ventilate, ventilate. "A cheap window-facing fan can clear a room's air in minutes," says May. Or consider opting for solid wood, especially for kitchen and bathroom items, since humidity amps up emissions. If you must go the pressed route, stick with plywood, which releases the fewest fumes.
The Pollutant: Mold
The Solution: Indoor air that's 30 to 50 percent humidity is comfortable for you but discouraging to mold (buy a $30 digital hygrometer at a hardware store to check your room levels). Spores love dark, damp corners, so once a week mop around your fridge, sinks, and toilets with a mild dish detergent or diluted hydrogen peroxide. Just be sure to dry everything thoroughly; mold can sprout in just 48 hours.
