These particles are a mix of gases (like carbon dioxide and volatile organic compounds), small solid particles (like dust and pollen), and small liquid droplets (like water). Some particles in the air may harm human health or the environment. The type and amount of particles in the air can affect your indoor air quality.<\/p>\n<p>Particles in indoor air that can be harmful include:<\/p>\n<ul>\n<li>Allergens<\/li>\n<li>Mold<\/li>\n<li>Chemicals, scents, and volatile organic compounds (VOCs)<\/li>\n<li>Smoke and fumes<\/li>\n<li>Certain gases like ozone, radon, and carbon monoxide<\/li>\n<li>Outdoor air pollution that gets trapped inside buildings<\/li>\n<\/ul>\n<h2 id=\"affects\">What Affects Indoor Air Quality?<\/h2>\n<p>Four factors affect indoor air quality:<\/p>\n<ul>\n<li>Ventilation<\/li>\n<li>Filtration<\/li>\n<li>Humidity<\/li>\n<li>Sources of pollution, allergens, and irritants<\/li>\n<\/ul>\n<h3 id=\"ventilation\">Ventilation<\/h3>\n<p>When a building or enclosed space has poor ventilation, it traps the air inside. This can make the indoor air more polluted and irritating than outdoor air. \u00a0Poor ventilation can also cause more moisture (higher humidity levels) inside.<\/p>\n<p>When a building has good ventilation, fresh air is brought indoors, and indoor pollution moves outdoors.<\/p>\n<h3 id=\"filtration\">Filtration<\/h3>\n<p>Central heating and air conditioning systems have filters to trap dust and other particles (pollution). Portable air cleaners also filter the air in the room where they are located.<\/p>\n<p>Filters need to be changed or cleaned regularly as per manufacturer\u2019s recommendations.<\/p>\n<h3 id=\"allergens\">Allergens<\/h3>\n<p>Indoor air can have a lot of allergens, such as <a href=\"https:\/\/aafa.org\/allergies\/types-of-allergies\/insect-allergy\/dust-mite-allergy\/\">dust mites<\/a>, <a href=\"https:\/\/aafa.org\/allergies\/types-of-allergies\/pollen-allergy\/\">pollen<\/a>, <a href=\"https:\/\/aafa.org\/allergies\/types-of-allergies\/insect-allergy\/cockroach-allergy\/\">cockroaches<\/a>, and <a href=\"https:\/\/aafa.org\/allergies\/types-of-allergies\/mold-allergy\/\">mold<\/a>. These substances irritate the airways of people with allergies and asthma. They can also trigger other symptoms like skin rashes.<\/p>\n<h3 id=\"humidity\">Humidity<\/h3>\n<p>Humid air creates small liquid droplets that can trap pollutants and worsen air quality.<\/p>\n<p>Mold and dust mites thrive in environments that have increased moisture. Keep the indoor relative humidity levels between 30-50% to reduce mold and dust mite levels.<\/p>\n<h3 id=\"scents\">Scents, Chemicals, and Other Sources of Indoor Air Pollution<\/h3>\n<p>Scents, both pleasant and smelly, can affect your indoor air quality. Any kind of scent can potentially \u00a0trigger asthma symptoms. These can include scented candles, fragranced potpourri, perfumes, wax warmers, and cleaning supplies.<\/p>\n<p>Some other items in your home can release gases called volatile organic compounds (VOCs). This is called off-gassing. VOCs can be 2 to 5 times higher indoors than outdoors.<sup>2<\/sup> VOCs can have some short-term adverse effects, but experts aren\u2019t sure yet of long-term adverse effects.<\/p>\n<p>Sources of VOCs can include:<\/p>\n<ul>\n<li>New furniture<\/li>\n<li>New mattresses<\/li>\n<li>New carpet<\/li>\n<li>New building materials<\/li>\n<li>Paint and varnish<\/li>\n<li>Cleaning supplies<\/li>\n<li>Air fresheners<\/li>\n<li>Pesticides<\/li>\n<\/ul>\n<p>Other sources of indoor air pollution include:<\/p>\n<ul>\n<li>Fuel-burning heat sources (like wood-burning stoves, gas fireplaces, kerosene heaters)<\/li>\n<li>Smoke from gas cooktops, candles, or <a href=\"https:\/\/aafa.org\/asthma\/asthma-triggers-causes\/secondhand-smoke-environmental-tobacco-asthma\/\">tobacco<\/a> use (e.g., cigarette smoking)<\/li>\n<li>Attached garages that store cars, motorcycles, or lawnmowers can add carbon monoxide to your air<\/li>\n<li>Radon (a gas that comes from the ground, gets trapped in a home, and can rise to dangerous levels)<\/li>\n<li>Ozone produced by ionizing air cleaners and emitted by office equipment is a lung irritant and can worsen asthma<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-19898\" src=\"https:\/\/aafa.org\/wp-content\/uploads\/2024\/04\/sources-of-outdoor-pollution-02-SM.jpg\" alt=\"Outdoor air pollution comes from manmade and natural sources.\" width=\"450\" height=\"450\" srcset=\"https:\/\/aafa.org\/wp-content\/uploads\/2024\/04\/sources-of-outdoor-pollution-02-SM-980x980.jpg 980w, https:\/\/aafa.org\/wp-content\/uploads\/2024\/04\/sources-of-outdoor-pollution-02-SM-480x480.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, 100vw\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-19897\" src=\"https:\/\/aafa.org\/wp-content\/uploads\/2024\/04\/sources-of-indoor-pollution-03-SM.jpg\" alt=\"\" width=\"450\" height=\"450\" srcset=\"https:\/\/aafa.org\/wp-content\/uploads\/2024\/04\/sources-of-indoor-pollution-03-SM-980x980.jpg 980w, https:\/\/aafa.org\/wp-content\/uploads\/2024\/04\/sources-of-indoor-pollution-03-SM-480x480.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, 100vw\" \/><\/p>\n<h3 id=\"outdoor\">Outdoor Air Pollution<\/h3>\n<p>Outdoor air pollution is caused by particles and gases that are not normally part of the air. This can come from pollen, smoke, dust, ozone, and emissions from cars and factories. All of these can create poor outdoor air quality.<\/p>\n<p>Bad outdoor air quality can make asthma and allergies worse. \u00a0Outdoor air can easily enter your home by coming \u00a0through leaks around doors and windows. It can also come in every time you open a window or door. In addition, you can bring pollen and smoke particles inside on your clothing.<\/p>\n<p>Allergens, scents, chemicals, and outdoor air in your home all work together to negatively affect your indoor air quality.<\/p>\n<h2 id=\"health\">How Does Indoor Air Quality Affect My Health?<\/h2>\n<p>Good indoor air quality is an important part of asthma and allergy management. Having your asthma and allergies under control can help you breathe better, sleep better, be more active, and be healthier overall. All of these things can improve your overall quality of life.<\/p>\n<p>If you are constantly in a space \u2013 such as your home, work, or school \u2013 that has poor indoor air quality, it may have a negative impact on your health. You may have trouble keeping your asthma and allergies under control. You may have more asthma attacks, emergency room visits, or even hospital stays.<\/p>\n<p>Some indoor air pollutants \u2013 such as tobacco smoke and radon \u2013 can have other serious effects on your health and can cause cancer.<\/p>\n<p>Air quality in schools is a serious concern. At school, children are often exposed to allergens such as dust mites, animal dander, and mold. Harsh cleaners and scents, as well as fumes from idling buses, can trigger asthma symptoms. Respiratory infections, which can trigger asthma symptoms, tend to spread more during school months, especially during the fall and winter.<\/p>\n<p>Exposure to asthma triggers at school may result in asthma that is harder to control, is associated with poorer school performance, and can lead to an increase in missed school days.<\/p>\n<p>Workplaces can have poor indoor air quality too. This can lead to <a href=\"https:\/\/aafa.org\/asthma\/living-with-asthma\/work-related-asthma\/\">occupational asthma<\/a>. Any work that causes small particles to enter the air can lead to poor air quality in the workplace. These small airborne particles can get breathed into the lungs and cause problems (e.g., tightening and inflammation of the airways). For example, bakers may inhale small airborne particles of flour. This can affect the lungs and cause\u00a0occupational asthma (otherwise known as baker\u2019s asthma).<\/p>\n<p>Poor indoor air quality in the workplace also affects more than our lungs. It can also impact mental function, ability to focus, and work productivity.<sup>3<\/sup><\/p>\n<h2 id=\"home\">How Can I Improve My Indoor Air Quality in My Home?<\/h2>\n<p>Here are 10 ways you can reduce the sources of allergens and irritants throughout your home:<\/p>\n<ol>\n<li>Set up regular cleaning routines.<\/li>\n<li>Vacuum carpets weekly. Replace carpets with solid flooring (like hardwood or laminate flooring) when\/if possible.<\/li>\n<li>Wash bedding and throw rugs weekly in hot water.<\/li>\n<li>Remove strong scents. Use unscented, gentle cleaners. Don\u2019t use scented candles, wax warmers, plugins, and potpourri.<\/li>\n<li>Fix leaks as soon as possible.<\/li>\n<li>Have everyone take off their shoes when they enter your home.<\/li>\n<li>Keep pets out of bedrooms.
