OASSAY FlexFlow: The World’s First Modular Purifier for Pure Water Anywhere

OASSAY FlexFlow is the world’s first truly modular purifier, built to remove 99.999% of viruses, bacteria, parasites, and microplastics from water. Instead of carrying bulky filters or compromising between speed, portability, and safety, this Kickstarter campaign delivers a 3-in-1 solution that adapts to every scenario. Tested to NSF/ANSI standards and validated by independent labs, FlexFlow is designed for travelers, outdoor adventurers, athletes, and anyone who wants reliable water purity without compromise.

Why one purifier can replace all your hydration setups

Dual-stage purification that goes beyond taste

At its core, OASSAY FlexFlow uses NanoFlex Carbon paired with a 0.1-micron hollow fiber membrane. The first stage reduces chlorine, ammonia nitrogen, and organic pollutants while improving taste. The second stage forms a mechanical barrier that blocks harmful microorganisms, parasites, and particles. Together, the stages deliver instant purification at flow rates of 8–20 ml per second — as smooth as drinking from a glass, without pumps or waiting.

A 3-in-1 modular design for real life

FlexFlow adapts to your environment with three distinct modes:

• Travel Mode connects directly to standard 28mm bottles, hoses, and taps. Perfect for international travel, where bottled water often needs extra purification.

  
  

• Sports Mode uses a collapsible silicone bottle that compresses when empty, clipping easily to a vest or pack for ultralight runs.

  
  

• Camping Mode combines the filter with a titanium or BPA-free PP cup, letting you boil, mix, or store water for meals and coffee outdoors.

Instead of packing multiple filters, bottles, and cups, one FlexFlow adapts to all of them.

Backwashable for a longer life

Most filters clog quickly and need full replacement. FlexFlow is different: its backwash system clears 90% of residues in seconds, restoring 80–90% of original flow. With up to 100 backwashes, each cartridge lasts up to five times longer than conventional filters, giving backers up to 500 liters — or 300 days — of clean water. That means fewer replacements, less waste, and more value.

Designed with sustainability in mind

Every part of OASSAY FlexFlow reflects thoughtful design. The recycled pulp packaging doubles as a storage case. The cap is inspired by the woodpecker’s beak — functional and durable, yet efficient. And by replacing disposable bottles, each unit helps reduce plastic pollution on a global scale.

OASSAY FlexFlow advantages for travelers and adventurers

Hydration you can trust anywhere

From rivers and lakes to questionable taps abroad, FlexFlow turns unsafe water into safe hydration instantly. Backpackers, athletes, and travelers no longer need to rely on bottled water or heavy gear.

A lighter pack, fewer decisions

Why carry three devices when one does it all? With Travel, Sports, and Camping modes, FlexFlow simplifies what you pack without sacrificing options.

Better taste, better performance

By cutting chlorine, heavy metals, and odors, FlexFlow ensures every sip is crisp and refreshing. Safer water that actually tastes good encourages more hydration during long runs, hikes, or hot travel days.

Long-term savings and eco impact

Each cartridge lasts as long as five traditional filters. That reduces both costs and environmental waste, making FlexFlow as sustainable as it is practical.

Backed by recognition and testing

OASSAY FlexFlow isn’t just a Kickstarter concept. It has already won international honors including the 2025 Golden Pin Design Award and a Silver Medal at Geneva’s Invention Exhibition. Independent labs have confirmed its performance, while OASSAY’s own testing ensures every batch meets the same high standard.

Why this Kickstarter campaign stands out

The OASSAY FlexFlow is not a prototype — it’s a finished, validated purifier entering production. Backers gain exclusive perks: up to 51% off Super Early Bird pricing, global VAT-inclusive shipping, and add-ons like the OASSAY sling or inflatable Air Sofa for complete outdoor comfort.

Unlike many crowdfunding campaigns, OASSAY has invested over five years of R&D into its NanoFlex Carbon technology. That commitment means reliability for backers and a product that sets a new benchmark in portable water purification.
