Water and air are essential for life. Arsenic, lead, and mercury have been identified by the U.S. Centers for Disease Control as the top three main hazards to human health when ingested through drinking water. In the air, particulate matter (PM) causes asthma, bronchitis, acute and chronic respiratory symptoms, which may lead to premature death.

Filtration solutions typically produce sludge and/or wastewater, utilize high pressure, demand electricity or require a large amount of space to operate.

Approximately 15 years ago, our Founder, CEO and Chief Scientist, Liangjie Dong, motivated by widespread arsenic poisoning in his native China, assembled a team to come up with a solution. After three years, the team achieved a breakthrough technology, mimicking the filtering ability of the human nose, a highly efficient filtering “system.”

Mesofilter’s first product, announced in 2005 was MicroNose™, iron-coated pottery granules featuring more than 1,000nm-sized pores. These pores filter and immobilize harmful pollutants and served as the basis for future generation products.

A few years later, Chevron asked Dong and his team to develop a new material that anyone, anywhere could use to filter water and air, and the team spent five years re-innovating the technology. We created a new ceramic granule that contains thousands of tiny pores with billions of nono-zero-valent iron needles that function like hooks to capture bacteria, inactive viruses, and adsorb heavy metals. This new product, MesoNose™, contains billions of meso holes (40-60 nm), far smaller than MicroNose’s 1,000+ nm micro holes. MesoNose pores are vastly more adsorbent than MicroNose’s larger pores, leading to a >99% removal rate.

MesoNose is the core technology incorporated into our newer products, NanoNose™ and now Mesopaper™.
