The most commonly-used water filtration media are silicon gels and activated carbon. These can only be used once, however. By contrast, not only can filters made with carbon nanotubes be reused, but they're also reportedly more effective at removing organic pollutants.​

There may be a new way of keeping orange and grapefruit peels out of our landfills – besides composting them, that is. Researchers have devised a method of using the peels to remove heavy metals from wastewater.

​​Oftentimes, the places that require water purification the most – such as developing nations or disaster sites – have the least in the way of infrastructure. Help could be on the way, however, in the form of water filters made from wood.​

​After the Fukushima nuclear plant accident occurred, millions of gallons of radioactive water was left over. Scientists from Texas and Russia, however, may know what to do with it. They've developed a type of carbon that can reportedly filter radionuclides from water.

​​NASA has released images showing Saturn’s enormous hexagonal north polar jet stream. The jet stream is large enough to swallow two Earth-sized planets laid either side of the dark, central polar storm.

Powder made from spent coffee grounds can be used to rid water of harmful heavy metal ions, although the powder then needs to be filtered out of the water. Scientists have developed a step-saving alternative, in the form of a filter made of coffee-impregnated foam.​

Peanut shells are generally considered to be a worthless agricultural byproduct. That could be about to change, however, as scientists have developed an air-purifying filter that utilizes the shells.​

Sigma has announced a line of filters which use a newly-developed Clear Glass Ceramic material to offer increased protection to your lenses. The new glass, which is produced using a special heat treatment, makes the WR Ceramic Protector filters thinner and lighter, while also being stronger.

The MSR Guardian acts as both water filter and purifier, eliminating 100 percent of all biological threats you might find in even the dirtiest of water.

For people in developing nations, getting clean water may soon be as simple as opening a book … The Drinkable Book, that is. Each of its pages is made from a thick sheet of paper impregnated with silver nanoparticles, that kill 99.9 percent of microbes in tainted water.

Sulfites are added to wine to keep it from spoiling, but they can also cause an allergic reaction in some people. The Üllo is designed to filter out those sulfites, once the wine is being poured.
