What is Indoor Air Pollution?
Harmful particles that originate inside and tend to stay inside become indoor air pollution. The most common culprits are dust, which is 70% percent dead skin, pet dander, mold spores, bacteria, microscopic organisms, smoke, and chemicals from cleaning products. Certain rooms contain higher amounts of certain allergens, but even offices and the interior of cars are susceptible to indoor pollution. None of these spaces have adequate ventilation to freshen air, and all of them have unnecessarily high humidity. The top indoor allergen is dust mite protein, created by mite carcasses and excretion. As with most allergies, exposure to dust mites can cause congestion, red and itchy eyes, itchy skin, or respiratory problems. These mites rely on a moist, warm environment with lots of dust; conditions that are common in most people’s living and work places. Millions of mites are sustained by water vapor and nutrients from our skin flakes and bacteria. The bedroom is the most affected as there ar
The air we breathe inside our homes can be 5 to 100 times more polluted than the air outside! The EPA identifies sources of indoor air pollution as second-hand cigarette smoke, building materials, pressed wood products, home cleaning products, pesticides, adhesives, personal care products and others. Without proper ventilation to outside air, you and your family may be at risk for the development of short term as well as long term health effects. Some short term effects are headaches, dizziness, shortness of breath, irritation of the eyes, nose, and throat. Most of the time these symptoms are easily treated by removing yourself from the source of pollution. Long term effects may show up years after the exposure or after several periods of exposure. Heart disease, cancer, and some respiratory diseases are a few of the possible health risks from exposure to indoor air pollution.
Indoor air pollution consists of toxic gases or particles that can harm your health. These pollutants can build up rapidly indoors to levels much higher than those usually found outdoors. This is especially true if large amounts of a pollutant are released indoors. Moreover, “tighter” construction in newer homes can prevent pollutants from escaping to the outdoors.

Indoor-air pollution is basically the accumulation of airborne levels of fine particles and volatile chemicals such as formaldehyde, which results from building materials, furnishings inside homes and offices and building systems like cleaning and equipment use. Formaldehyde is a colorless, strong-smelling gas. It is widely used to manufacture building and household products, especially as an adhesive resin in pressed wood products. What are the health effects? Indoor-air pollution is one of the main causes of what is known as the Sick Building Syndrome (SBS). This phenomenon is the mysterious condition wherein many occupants experience various health or comfort problems connected to the time spent in a particular building, for which no specific illness or sickness has been identified. It has been established however that Sick Building Syndrome may also be caused by acoustic, thermal, illumination and other aspects of indoor environment. Health effects of indoor-air pollution can range
