Beat mold in the bathroom

Install a ventilation fan; run it during every bath and shower to reduce mold-friendly moisture. At the very least, leave the bathroom door ajar or crack open a window. Mold also thrives in damp corners, so once a week, wipe around the sink, tub and toilet.

Some emit volatile organic compounds (VOCs), which can exacerbate respiratory problems. VOCs have also been shown to cause headaches in susceptible people.

Ditch the vinyl

These types of shower curtains emit VOCs, as well as other potentially lung-irritating compounds, like phthalates. A nylon curtain, which can be thrown into the wash as needed, is a better choice for your health and the environment.

Keep it covered

Put dust mite-proof covers, ideally microfiber ones, on mattresses, box springs, comforters and pillows. They'll prevent the critters from penetrating your bedding. Wash your sheets once a week in hot water (aim for at least 130 degrees), then throw them in the dryer at a high temperature.

Even a small trickle from the pipes under the sink can lead to mold.

For people with asthma who have a certain gene variant, living in a home with mold may increase the risk of a severe attack, according to a 2010 Harvard Medical School Study.

Consider a couch made from leather: It's less likely to harbor allergens. If you want to hang on to your upholstered one, run a HEPA vacuum over it at least weekly.

Invest in a vacuum

Look for one that has a HEPA filter and a certification mark from the Asthma and Allergy Foundation of America. This means it not only removes a significant amount of allergens but also prevents them from leaking back out into the air.

Check your temp

Keep the digits below 68 degrees; dust mites thrive in toastier conditions. Use a hygrometer (about $10 at drugstores) to measure in-home humidity, too. The sweet spot: 35 to 50 percent. Anything lower will dry out nasal passages; anything higher encourages mold. (Another reason to keep your thermostat set at 68: Keeping your home too cozy-warm can lead to weight gain. It's one of the 10 ways your house is making you fat.)

Dust smarter

Do it (at least) once a week to remove allergens from surfaces. Use a microfiber cloth or dusting wand—the superthin fibers trap more debris than regular towels or dusters.

Use a filter for forced air systems

Your best bet: a pleated filter that has a MERV (i.e., effectiveness) rating of between 8 and 12. You can have it installed in your system directly. If you've got baseboard heat, you may want to purchase a few portable HEPA filter units (they cost $100 and up) and place them around the house. You probably don't need to get your air ducts professionally cleaned—research doesn't prove that doing so improves air quality, and it can actually make things worse by stirring up allergens and other particulates. Replace your filters regularly, based on the manufacturer's instructions.

Box it up

Clutter is a dust-magnet, not to mention bugs, mold, and mice. Recycle old newspapers, magazines, cans, and grocery bags every week, and for everything else, store as many items as possible in plastic bins to minimize dust.

Repair any water damage that can encourage mold growth. Even if you have mold only in your basement, your heating or cooling system can pump it into other parts of your house.

Degrime your gutters

Reducing allergen exposure outside may reduce your allergy symptoms inside by keeping your body from getting overloaded with irritants. Remove dead leaves near the foundation and gutters; they lead to dampness, which fosters mold.

Wash your kids' stuffed animals

Your kids' stuffed animals are a magnet for dust mites. Keep only two or three on your little one's bed; put the rest in plastic containers. Wash them at least once a month. Or just put them in a hot dryer for 20 minutes to zap mites.

Take shoes off outside

Your shoes pick up allergens from outside (hello, pollen and leaf mold!) and bring them indoors. Buy an outdoor mat so you can rub your soles free of debris before walking inside, or take off your shoes and leave them by the front door.

Fish tanks

Nemo may be one of the few pets that are hypoallergenic, but the tank he's frolicking in is an incubator of mold. Give the tank and filters a good scrubbing at least once a month.

Don't overwater your plants

While certain houseplants (chrysanthemums, for example) reduce indoor air pollutants, you can have too much of a good thing. "If you don't clear out debris, the soil can harbor mold," Dr. Portnoy says. Limit the number of indoor plants and be sure you don't overwater them.

Studies have shown that laser printers emit VOCs and particles that are associated with asthma and can harm the lungs. Keep yours in a well-ventilated area at least 10 feet away from your desk.

Go green to get clean

To eliminate allergens, you need to scrub. Problem is, some cleaners can make symptoms worse. "Many have quaternary ammonium compounds, or quats, and bleach, which are asthmagens," says Johanna Congleton, PhD, senior scientist at the Environmental Working Group (EWG) in Washington, D.C. In fact, one study of more than 3,500 people found that those who used spray cleaners at least once a week had a 30 to 50 percent increased risk of asthma.

The top indoor allergens

Credit: Getty Images

First up: Dust mites.

More than 25 percent of us are allergic to these tiny bugs that live in dust. The critters munch on skin particles and dander, so you'll find them wherever there are people and pets. You're not allergic to the mites themselves but to a protein they excrete. The mites' waste can hang out on pillows and mattresses or in carpeting and not bother you, but when you disturb them—say, by fluffing your duvet—they'll fly into the air and trigger symptoms.

Household pets

Cat allergy is the most common pet allergy, but at least 15 percent of us are allergic to both cats and dogs. It's not their fur per se that has you sneezing but their dander, saliva and pee.

Roaches and rodents

Up to 98 percent of urban homes have these allergens, even if they can't be seen. Apartment dwellers may find themselves battling roaches, and suburban and country home owners may face rodent infestations. As with your furry friends, you're allergic to their feces and saliva, not just to the critters themselves.

Mold

You've probably heard of toxic black mold (aka Stachybotrys chartarum), but many kinds of indoor mold can cause allergies. While it tends to grow in dark, damp spots, this allergen can sprout up anywhere that water has leaked. The best way to tell if you have mold is to see it (it's usually black, brown or green) and smell it (it's got a musty odor). Get rid of mold by scrubbing with a solution of 1/2 cup of bleach and 1 gallon of water.
