There are several types of pollution that can affect your health and environment. The EPA sets standards for 6 “criteria air pollutants” which are: ozone, particulate matter, carbon monoxide, lead, sulfur dioxide, and nitrogen dioxide. Both indoor and outdoor pollutants can be found inside your home, especially when outdoor pollution levels are particularly high. Common indoor air pollutants include things like cigarette smoke, harsh chemical cleaners, chemicals from newly installed flooring, remnants of construction, and more. Indoor air quality can sometimes be worse than outdoor air quality. This is especially true during cold winter months when we seal our homes for warmth, preventing proper air circulation and causing a buildup of pollutants. Some of the most prevalent air pollutants in the U.S. are ground-level ozone (smog), and particle matter. Ozone Ground-level ozone, or smog, is created when pollutants (NOx and VOCs) from cars, refineries, power plants, and other sources chemically react along with sunlight. Breathing ozone can lead to throat irritation, chest pain, coughing, and other respiratory ailments. Particulate Matter Particulate matter (PM), or particle matter, is created when microscopic solids mix with liquid droplets in the air. Particle pollution can be comprised of allergens, acids, metals, and other components. According to the EPA, extended exposure to PM can lead to reduced lung function and bronchitis, while short-term exposure can cause temporary irritation. Who is Most at Risk of Air Pollution? Certain populations are more vulnerable and are at a higher risk of suffering the ill effects of breathing in polluted air. Children, the elderly, and chronic disease sufferers are the most likely to experience symptoms. Lung disease, asthma, heart disease, COPD, and other respiratory illnesses can worsen with exposure to indoor and outdoor air pollution. If you have children, are elderly, or are otherwise health-conscious and want to protect yourself and your family from the harmful effects of pollution, consider buying an air purifier for your home or office. Why We Recommend Air Purifiers for Combating the Effects of Pollution Clean Air For All While pollution is especially harmful to certain vulnerable populations, everyone’s health is impacted by poor air quality. The quality of the air we breathe is often not considered a crucial part of our well-being. We consider the foods we eat, how active we are, and how clean our water is as part of maintaining a healthy life, but most of us don’t consider the role clean air plays on our overall health. Long-term exposure to air pollution has a negative effect on our bodies. Air purifiers provide clean air to everyone, regardless of age or medical need, and are a key part of maintaining a healthy lifestyle. Purifiers decrease air pollutants, provide relief to chronic disease and allergy sufferers, and help everyone breathe healthier air. A Worthy Investment in Your Health Air purifiers are designed to filter out pollutants in the air you breathe, from allergens and dust to smoke and particle matter. We recommend a HEPA air purifier for fighting indoor air pollutants, such as the Alen BreatheSmart 45i. High quality HEPA purifiers filter particles as small as 0.3 microns, effectively removing dust, bacteria, mold, and other pollutants. Purifiers are an excellent solution for improving your home’s air quality. Purchase one for each room in your home, or start with units for the rooms you spend the most time in. Investing in an air purifier is an investment in your health, and one that will help you breathe cleaner and safer air.
