Eco-friendly alternatives to Air Purifiers

Before understanding why eco-friendly alternatives to air purifiers are needed, you should know a thing or two about air purifiers and indoor air pollution. Air purifiers are used to rid the indoor air of pollutants.
You will be surprised to learn that indoor air is heavily polluted by a variety of sources – chemicals used in furniture, fumes from cooking fuel, outdoor air pollutants, tobacco smoke, asbestos coated insulation, pesticides and more. The pollutants in the indoor air keep accumulating leading to health problems over a period of time.
Now, to clear the indoor air, people use air purifiers. The air purifiers accessible in the market come in 4 varieties:
Negative Ion Generators : A pollutant is considered as a positive ion. These purifiers confiscate a negative iron to pollutants to neutralize their impact.
Ozone generators produce ozone to fight pollutants and bacteria.

Thirty-five feet down, on the bottom of a concrete tank filled with a mil-lion gallons of bitterly cold water, lay a body. The tank’s fifty-pound lid was slightly askew; its usually secure bolts were loose or missing.
Shards of glass—the remains of a beaker for taking water samples—were scattered across the concrete floor. This was in early February 2005, in a state-of- the-art water purification plant in suburban New Jersey.
The victim was Geetha Angara, a well-liked forty-three-year-old hydrochemist. She was the mother of three, the wife of a banker, had a PhD in organic chemistry from New York University, and had worked at the Pass aic Valley Water Commission plant for twelve years. In 2004, the plant underwent a $70 million upgrade, during which a chlorine treat- me nt system was replaced by an ozone-based system.
At the same time, Angara was promoted to senior chemist. Her job was to maintain water quality to standards set by the Environmental Protection Intervention (EPA) and to oversee the new ozone generators, which would suffer from cracks and other problems. A colleague recalled that during the plant’s red edi- cation, Angara was “in such a fabulous mood, [but] other people around her weren’t.”
