VOCs (Volatile Organic Compounds)

  • VOCs (Volatile Organic Compounds) are gases and chemicals emitted by a variety of products and objects, many of which can be found in your home. In fact, the U.S. Environmental Protection Agency (EPA) numbers these products to be in the thousands. The EPA cautions that "many VOCs are consistently higher indoors (up to 10 times higher) than outdoors."

  • The EPA warns that some VOCs "may have short and long-term adverse health effects." Examples include paints, cleaning supplies, disinfectants, cosmetics, pesticides, building materials, furnishings, hobby products – and the list goes on. Many of these products emit VOCs even when they are not in use (such as furnishings built with products containing formaldehyde).

This is the best air cleaner/purifier that I was able to find. Have used for approximately 3 years and this product does a heck of a job. We have two dogs and many people have commented how odorless our house is, no evidence of dogs! [Product Purchased: 457-0442]
I use the Blueair filter 24/7. My allergies are showing improvement especially this time of year when they are the worst.
