DIY air filter successfully filters out indoor air pollution: examine

Windfall, RI — Use of an “simple to assemble” DIY air filter can shield constructing occupants in opposition to sickness precipitated not solely by viruses but additionally by two kinds of chemical pollution, outcomes of a latest examine present.

Researchers at Brown College and the Silent Spring Institute measured the focus of semivolatile natural compounds in 17 rooms earlier than and after utilizing do-it-yourself Corsi-Rosenthal boxes. Developed in response to the COVID-19 pandemic, the containers are made of 4 filters with a minimum efficiency reporting value of 13, duct tape, a 20-inch field fan and a cardboard field. 

Outcomes present the containers lowered the concentrations of per- and polyfluoroalkyl substances, or PFAS – often known as “endlessly chemical substances” as a result of they break down slowly over time – by 40%-60% and phthalates by 30%-60%. Phthalates are a gaggle of hormone-disrupting chemical substances generally present in constructing supplies and private care merchandise. They’ve been linked to a number of well being issues.

“Any such extremely accessible public well being intervention can empower neighborhood teams to take steps to enhance their air high quality and subsequently, their well being,” lead examine writer Joseph Braun, an affiliate professor of epidemiology at Brown, mentioned in a press launch.

Added examine co-author Robin Dodson, a analysis scientist on the institute: “The discount of PFAS and phthalate ranges is a superb co-benefit to the Corsi-Rosenthal containers. These containers are accessible, simple to make and comparatively cheap, they usually’re at the moment being utilized in universities and houses throughout the nation.”

The examine was published online within the journal Environmental Science & Know-how.
