According to the Environmental Protection Agency (EPA), indoor air can be 2–5 times more polluted than the air outdoors. Indoor air pollution is among the top 5 environmental health risks. The best way to address this risk is to control or eliminate the source of pollutants and to ventilate our home. However, a bad weather condition or undesirable level of contaminants outdoor may limit the possibility of ventilating our house. Then an air purifier may be useful in improving the indoor air quality. In April, we look into our indoor air quality and the various types of air cleaners in improving our environment.
Our home, office or even schools can be sites of hazardous chemical contamination. This contamination has seriously affected our human health. Toxic chemicals can be found in the air, water and our human body. They are part of what we eat, where we work and how we live. Despite their prevalence in our lives, many chemicals are hazardous or toxic, especially to children.
