The nets are sold through the WHO, the UN children's agency UNICEF, the UN High Commissioner for Refugees and non-governmental organisations active in the fight against malaria.
According to the Roll Back Malaria campaign, using the insecticide-treated net cuts the chance of catching malaria in half. The disease causes headaches, high fevers, vomiting and other symptoms.
The success of the net has led to expansion, with A to Z Textile Mills opening a second factory in 2006 in Kosongo, some 18 kilometres (12 miles) from Arusha. The operation now employes 4,700 people, most of them women.
"The Olyset model produces a vital public health product and simultaneously boosts economic development in Africa," Tanzanian Vice President Ali Mohamed Shein said of the nets at the official inauguration of the factory last week.
Factory director Kaplesh Shah said the chemically-treated net was cheaper than conventional those developed in the 1980s, which have to be soaked every four to six months to be effective.
"Our main clients are UN organisations or NGOs. We are trying to attract the private sector but it's not easy," said Shah.
While the Tanzanian government was supporting his factory, he said production had been hampered by the many power cuts in the region. Distribution of his product has also been difficult.
