Researchers produce air nanofilters with 99% absorption

TEHRAN, Feb. 11 (MNA) – Iranian researchers have produced a type of nanofilter from nanomaterial that can absorb 99 per cent of various air pollutants and chemical gases such as Co and Co2.

Dr. Mohammad Mehdi Shirmohammadi, the CEO of a knowledge-based company at Tehran University Science and Technology Park, told Mehr News that his team has been successful in mass production of a type of air filter through nanotechnology and by using activated carbon nano-silver.

According to him, the nano filter can be used in cabin air filters in vehicles, household air conditioners, respiratory masks, as well as cement, steel and petrochemical industries.

“We used six layers of mask together which are a composition of activated carbon, nano material and a layer for dust absorption. These layers help increase the absorption efficiency up to 99 per cent,” he said.

He went on to add, “we are planning to increase our daily production to 10,000 filters, and for future plans, we will be able to produce 7 million filters per year.”

“We have so far exported this product to Persian Gulf littoral states and Iraq,” he added.

According to him, the masks have been produced by using nano material instead of nano fiber which has increased their efficiency and allowed individuals to use the mask without having any breathing problems.
