Top 10 Best Air Purifiers

These days, the level of indoor air pollution is higher than the level of outdoor air pollution. The US Environmental Protection Agency says that 'indoor air pollution can be between 2-5 times higher, and sometimes as much as 100 times higher than outdoor air pollution'. Air pollutants such as dust, pollen, dander, cigarette smoke, fibers, etc. can result in headaches, nausea, body ache and other health issues. Air purifiers have been designed to filter the indoor air and render it free of dust and allergens. Air purifiers are meant to improve the air quality, and are available in a variety of types and sizes. They have many health benefits and are important to people suffering from allergies and asthma. However, choosing the best air purifier is also essential. Before purchasing an air purifier one should decide whether it is needed for the whole house or for a particular room. Then one has to decide on the type of air purifier required: HEPA (High Efficiency Particle Arresting), Electrostatic Air Purifiers, Ion Generator Air Purifiers, Carbon Air Purifiers or Ozone Generator Air Purifiers. Of these types, HEPA (High Efficiency Particle Arresting) air purifiers are considered to be the most efficient air purifiers. They are known to remove 99.97% of the air pollutants including bacteria, viruses and microorganisms.
