Ask drivers how often they should change oil in their cars and you’ll likely hear an answer that’s been repeated for generations: ‘three months or every 3,000 miles, whichever comes first.’ The performance of older automobile engines and the low quality of motor oil demanded a short interval be followed to avoid expensive repairs. However, that may no longer be valid as improvements to autom...

The world’s rainforests are an ecosystem that supports thousands of animal species, but they also have a lesser-known function that is equally important: acting as natural air filters. What does that mean? Rainforests create 20 percent of the world’s supply of oxygen, which means that the more trees we lose due to deforestation, the less supply of clean air in the world. (1) The plig...

One of the consequences of air pollution that is seldom talked about is the effect of corrosion on man-made materials throughout the world. As air pollution levels have risen in industrialized countries, so too has there been a corresponding increase in corrosion levels. But this doesn’t just affect man-made monuments; it also affects things closer to homes such as vehicles, barbecue grills,...

Recent studies have found that living near an airport could be hazardous to your health. One air quality study found that neighborhoods as far as 10 miles away from Los Angeles International Airport (LAX) are contaminated with high levels of ultrafine particles that can easily be swallowed or inhaled. These particles are hazardous to human health because they can penetrate in to the lung...

As outdoor pollution worsens throughout the world, especially in large countries such as China and India, it has a direct effect on indoor air quality. That’s because polluted air that is drawn indoors can pose a direct threat to your health if you don’t take steps to lessen its adverse effects. One of the ways that you can reduce indoor air pollution is through the use of air purifiers, dev...

While statistics may sometimes overwhelm you with numbers, it is important to cite some figures when discussing outdoor air pollution, indoor air quality and the need for an effective air filtration strategy to combat airborne contaminants. According to the EPA, indoor air quality (IAQ) is defined as the quality of air within a commercial building or residence as measured by the number o...

When you hear the term ‘high-efficiency air filter’ what do you think? Like most people, you probably think of hard-working filters that can improve the air you breathe, and that’s true. But do you understand how a filter achieves high-efficiency? Or what that phrase even means? This is important because without understanding the basic standards of air filter efficiency, you won’t unders...

The heating, ventilation and air conditioning (HVAC) system in a home or workplace not only delivers the air that helps regulate the temperature and humidity, but it can also determine the quality of the air that you are breathing. That’s because the outdoor air that is drawn through the HVAC system, and recirculated are filled with dust, dirt and other particles that compromise the quality ...

Rising air pollution levels throughout the world are not just an environmental concern. Scientists have known for decades about the link between worsening air pollution and an increase in the risks for heart disease, lung cancer, and reduced lung function. But it’s only recently that the link between air pollution levels and life expectancy has become more obvious. And that link is stronger ...

Understanding Sick Building Syndrome The U.S. Environmental Protection Agency (EPA) defines Sick Building Syndrome (SBS) as, “situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.” (1) SBS does not always originate from an entire building and can be ...
