Filter

A new water purification technology developed by researchers at Princeton University doesn't require filters, instead relying on the injection of CO2 gas to change the water's​ chemistry and separate waste particles based on their electrical charge.

Researchers at the University of Manchester have developed a graphene-oxide membrane with a scalable, uniform pore size that can filter out even the smallest salts, giving it potential for producing drinking water from salt water without affecting the flow of the water too much.

Engineers at the Washington University in St. Louis (WUSTL) have developed graphene-based biofoam sheets that can be laid on dirty or salty dams and ponds to produce clean drinking water, using the power of the sun.

​To combat health risks posed by air pollution, car manufacturers are working to make sure we're able to breathe easy in their cars. Tesla has Bioweapon Defense Mode, and now Audi is getting on board with a new filter that removes particulates, gases and allergens from the air.

Material scientists at Stanford University have developed a highly effective semitransparent air filter that can collect 99 percent of harmful pollution particles, thanks to a dense web of nanoscale polymer fibers. The low-cost filter doesn't require power to function.

The Camelbak All Clear bottle integrates a UV purification system into its cap.

The Protexo is a device that blows cool air on asthma sufferers as they sleep, to keep allergens away from their "breathing zone."

Researchers have discovered that activated carbon cloth is highly effective at removing pollutants from air and liquid.

Researchers from Stellenbosch University have patented a "tea bag" style water filter.

The Emergency Bra is a protective device that transforms from a bra into two respiratory pace masks to filter out harmful airborne particles.

Stanford researchers have developed a new kind of water purifying filter that is about 80,000 times faster than existing filters, is low-cost, has no moving parts and uses very little power.

Bobbles are reusable plastic water bottles that have an activated carbon filter built into the drinking spout.
