Research shows that indoor air pollution, often caused by dust mites and mold, can be up to 10 times greater than outdoor pollution. Use these tricks to avoid allergy triggers in your home.

Avoid the outdoors in the morning

Not only do many people with allergies experience more sneezing and itching in the morning, but many trees release their pollen in the air at first light, and ragweed pollen tends to fly most thickly at midday—when it'll stick to your clothes and get carried indoors. If you want to work out, do it later in the day. These 12 natural allergy remedies provide relief.

Change your clothes and shower when you come indoors

Even if you don't feel dirty, pollen clings to your hair and clothes where it can easily irritate your nose and eyes, and contribute to indoor air pollution. Don't have time for quick rinse? At least wash your hands to remove lingering pollen, especially before making contact with food or your face.

Water indoor plants sparingly

Overwatering can contribute to the growth of mold, and any water that leaks on to the floor invites mold growth as well. Put pebbles on top of the dirt to discourage mold spores from getting into and polluting the air. These tips can keep your houseplants happy and healthy.

Clean the tray under the fridge with a bleach solution and sprinkle with salt


The tray is a veritable mold magnet. Adding salt reduces the growth of mold and bacteria. Clean under the refrigerator occasionally; food can become trapped there and become moldy, then the mold spores are blown into the kitchen air every time the compressor kicks in. Check out these 60+ household uses for salt.

Wash all your bedding in very hot water every week


It’s the best way to kill those pesky microscopic dust mites that love your bed even more than you do, which add to the air pollution in your bedroom and home. Are you making these other surprising laundry mistakes?

Wash the shower curtain in hot water and bleach every month


Or use cheap shower liners that you can replace every couple of months. To help stop mold growth in your bathroom, always run the exhaust fan or open a window or door when using the shower to help keep surfaces dry. Another option: Run a small portable fan (away from water sources) during and after showers. Also, check to see that the vent on the outside of your house where the exhaust exits isn’t blocked by leaves.

Give stuffed toys a deep freeze


That teddy bear could be riddled with dust mites! Regularly slip stuffed toys into a freezer bag and let them chill for 3 to 5 hours. The cold will kill any dust mites that could contribute to indoor air pollution. Check out these other genius non-food ways to use your freezer.

Keep your thermostat set above 65°F in the winter


If you set it too low, you’re encouraging the growth of mold in damp air. The heat dries out the air, preventing mold growth and pollution. Of course, too-dry air can also irritate your lungs and sinuses. The perfect humidity in a home is around 50 percent.

Clean out your gutters and make sure they’re not clogged


Clogged gutters can result in water seeping into the house, leading to mold growth, which can exacerbate allergies. Next time it rains, check your gutters. If you see water leaking out of end caps, flowing on the outside, or dripping behind them, it’s time to get out the ladder.

For every load of laundry you dry, 20 pounds of moisture has to go somewhere! If your dryer is vented to the garage or basement, you’re just asking for mold buildup.

Declutter the right way

Do this regularly: Throw out or give away coats and other clothing you haven’t used in the past year. Put sports equipment in the garage or basement where it belongs. Slip shoes into hanging shoe bags. When you finish, you should be able to see all your closets’ floors and back walls. Now give everything a good vacuum and you’ll have significantly reduced the amount of dust in your house and cut down on your indoor air pollution.

Use doormats with synthetic fibers

Doormats made of natural fibers such as wicker can break down and become food for mites, mold, and fungus that then get tracked into your home with every new guest. Wash all mats weekly.

Mud isn't the only thing you track into your home. Wearing your shoes inside carries dust, mold, and pollen to every room in your house. Parking your shoes by the door keeps your floors clean and reduces indoor air pollution.

Turn on the AC


Air conditioners remove mold-friendly moisture and filter allergens entering the house. Just make sure to clean or change the filters often or you’ll just make things worse.

Keep your pets clean


Just like you take off your shoes, always make sure to wipe off your pet's paws when they come in from being outdoors. Toweling off their coat can also help prevent the spread of pollen indoors. You can also try giving them frequent water baths to help dissolve the natural, allergy-causing substances in their sweat and skin that spread to their fur.
