Looking to best other squeezable filter bottles, the Oassay FlexFlow uses a compact filter to remove tiny viruses, bacteria, heavy metals, hydrocarbons and even fluoride. The bottle passes water at drinkable flow rates for seamless hydration.

We know Lifestraw best for lightweight, ultraportable water filter and purification products aimed at backcountry use, but its all-new Escape is a different beast. The jug supplies groups with over 5 gallons of clean drinking water per fill-up.

Using ultrasonic waves and a salt bath, a research team has altered the surface of glass. The brand-new method may lead to glass made without the use of harsh chemicals for self-cleaning windshields, germ-busting surfaces, or maybe even better beer.

In Frank Herbert's Dune novels, water is so scarce on planet Arrakis that it's absolutely sacred to the desert-dwelling Fremen, who wear special 'stillsuits' that capture and recycle nearly all their body fluids. Now, YouTubers have built one for real.

As recent history proves, airborne respiratory infections are not to be trifled with. Now, a new sprayable coating applied to standard air filters might give us a leg up in the war against the pathogens that cause these diseases.

While we've seen quite a few filtration systems for making polluted water drinkable, many are quite complex, or utilize costly materials. By contrast, an experimental new setup simply requires users to inject dirty water through a layer of cellulose.

Loading your bike with heavy bottles of water is a drag, but what else can you do on long rides? Especially if you don't use a hydration pack? Well, the Extract Water Filter lets you fill your bottle with water that you find along the way.

Years before Samsung and others started tackling microplastic from machine washes escaping into the environment, there was Slovenia-based PlanetCare. Now the company has announced its second-generation external filter.

Although HEPA filters and UV lights are effective at neutralizing bacteria in hospitals, homes and other settings, they do have their drawbacks. A new light-activated material known as LumaFlo, however, is claimed to have them both beat.

At CES 2023 in January, Samsung hatched a plan to stem the tide of microfibers shed during washing cycles from entering seas and oceans via a special wash program and an external filter. Now that Less Microfiber Filter has launched.

Back in 2020 we told you about the QuenchSea, a foot-pump-powered portable device for desalinating sea water. Well, its makers are back with the QuenchSea Reel, which uses deep-ocean water pressure to do the same job.

There’s no debate that microplastics present an ever-increasing ecological and health threat, but given their size, they're incredibly hard to remove from water. Now, some scientists believe sound waves and microfluidic technology may hold the key.
