Where’s the waste filter media of air Purifier

 In the today’s "haze economy" developed, the air purifiers became the new darling of the domestic appliance industry.

  “How to deal with the old filter media of your home air purifier?” In the home appliance stores in Nanjing, reporters interviewed several random people, the answer is the same: just throw into the trash can. More than one brand of air purifier sales staff said that the manufacturers has no special attention to the disposal of old filter media. But these waste media, especially the chemical fiber filter, was  incinerated & landfill processing as rubbish, exhaust gas produced by waste residues can cause secondary pollution to the environment.

  "We can not solve an environmental problem at the same time, bring new environmental problems." Study filter media fabric nearly two decades of Donghua University professor Shen Henggen said.

  He told to reporters, compared with home air purifier, dust bag filter media for cleaning exhaust in the industry has greater usage.

  Take the exhaust gas purifying dust bags of coal-fired power plant for example, 300,000 kilowatts coal-fired generating units would need at least 15 tons of filter material, these mainly chemical fiber filter material, to be replaced every two and a half years to four years. "Simply burning & burying the old filter media will cause secondary pollution." Mr. Shen Henggen said. “Moreover, these chemical fibers are extracted from the oil, very valuable, one-time use is a waste.”

      Mr. Shen Henggen called on relevant departments to pay attention to the recovery of the filter material: such as chemical fiber, can become filled or insulation materials through roughed; Also, the body of air purifier can be used steel. Compared with plastic, the recycling rates of steel is higher, and more environmentally friendly energy.
