Its spores can cause a stuffy nose, cough, sore throat, and itching. If you have mold allergies, lung problems, or a weak immune system, these spores can lead to a serious lung infection. Mold grows where there’s moisture, so watch for leaks in plumbing, walls, and the roof. Use air conditioning or a dehumidifier to keep humidity levels under 50%. Clean up mold with soap and water, or use 1 cup of household bleach in 1 gallon of water.
Rock and soil release this gas. There’s a little in the air around us, but it’s dangerous if too much is trapped in your home. Its radioactive particles cause damage when breathed in or swallowed. It gets into buildings through cracks and holes in floors and walls, and around plumbing and wiring. You can’t smell or see radon, but a simple test can tell you if your home has too much. If you do, hire a certified contractor to make fixes.
It can trap dust, mold, dust mites, dirt, and other irritants. When you clean it or walk on it, those particles can get into the air. The chemicals used to make and install some carpeting could be bad for you, too. Consider hard flooring instead, or use throw rugs you can clean outside your home. If you can’t get rid of your carpet, use a vacuum with a HEPA filter on it at least three times a week, and steam clean it every year.
Their poop and parts of their bodies can settle in the dust on your floors, bedding, and furniture. When you breathe those irritants in, it can trigger allergies and breathing problems, including asthma. It helps to keep your house as clean and dry as possible, especially fabrics and carpet.
Furnaces, fireplaces, water heaters, dryers, and cars can make this gas you can’t smell or see. It can be deadly if it isn’t vented out and it builds up in your home. Install carbon monoxide detectors inside, and use appliances properly. The symptoms of carbon monoxide poisoning are a headache, shortness of breath, blurry vision, and feeling dizzy, confused, weak, and nauseated. If you have them, get fresh air right away, then call 911.
It adds moisture to the air. But don’t just set it and forget it. Humidity above 50% may invite bacteria, fungi, and other germs. And water starts to condense on windows and other home surfaces around 60%. Plus, the humidifier itself can grow mold and bacteria that blow into the air unless you clean and dry it daily. You can measure humidity levels with a tool called a hygrometer from the hardware store.
They can hold dust mites, pet dander, mold, and other allergens. The same goes for blankets, clothes, rugs, sheets, and other fabrics around your house, but curtains are often harder to clean. Use blinds instead, and dust them regularly. Or get curtains that are safe to wash in 130-degree water to keep the dirt and allergens to a minimum.
