Unlike barrier filters which trap expectorated matter whilst allowing viruses and bacteria to pass through, Vitalograph filters use an electrostatically charged material that traps expectorated matter ...

The CareStar breathing system filters from Dräger provide an excellent and cost-efficient alternative. Due to its highperforming electrostatic filtration medium, CareStar supports protection of the ...

Researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources -- lakes and rivers -- at a significantly higher rate ...

As important a technology as water filters are, they get less effective as bacteria builds up on their surface. Now, researchers at Washington University in St. Louis have developed a new type of ...

Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It's highly efficient, long-lasting and environmentally friendly -- and could provide clean water ...

FLINT, MI - While the point-of-use water filters provided by the state clear lead from Flint drinking water, they actually have the potential to increase bacteria levels in the water, researchers say.

Water filters on the market today can't always stop bacteria from passing through. The problem is a structural one. It's hard to get the pore sizes to align properly, leaving room for the pathogens to ...

A water-purifying filter made from normal cotton coated in nanostructures has been developed by researchers at Stanford University in the US. They say that the device, which works by killing bacteria ...

Researchers at University of Cincinnati have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a ...
