Air Ducts清洁是个骗钱工作,基本无用。,美国国家环保局已经官方证明,家庭通风管道与锅炉清洁从没有研究来证明它可以减少健康风险,或者减少家庭里的空气灰尘。Air Ducts清洁基本就是个商业骗局。
这是EPA官方网站的解释:
https://www.epa.gov/indoor-air-quali...r-home-cleaned
"Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts."
"EPA does not recommend that the air ducts be cleaned routinely, but only as needed."
