99% bacteria removal. Replaces 6,000 plastic bottles.
3-stage filtration with 0.1 micron hollow fiber membrane. BPA-free, portable, and built for life — from campus to wilderness to flood zones.
Every sip of unfiltered water is a risk. Every plastic bottle is a promise to the planet — a bad one.
Not another plastic bottle. Not another promise. A real, filtration-first water bottle.
Click each stage to explore the technology powering HYDRA.
The first line of defense. A mechanical pre-filter captures large particulates before they reach the main membrane, extending filter life dramatically.
The heart of HYDRA. Thousands of hollow fibers with 0.1 micron pores physically block bacteria, parasites, and microplastics — no chemicals needed.
This final layer serves as a critical fail-safe for your drinking water. When the primary filtration stages reach their maximum capacity and their pores begin to widen, this fine mesh steps in. It catches any escaping particles, which intentionally clogs the membrane and completely blocks water flow. This built-in shutoff guarantees you never accidentally consume unpurified water once the filter's lifespan is over.
Everything you need for pure water everywhere.
The complete 3-stage filtration bottle. Includes one filter cartridge. Ready to use out of the box.
Keep the pure water flowing. Replace every 3,000L or 24 months for optimal performance.
Not all water bottles are equal. The difference is in the details.
For every 10 bottles sold, HYDRA donates 1 to flood-affected communities and refugee camps. Clean water shouldn't be a luxury.
Four founders united by a single belief: clean water is a right, not a privilege.
Backed by mentors from BUET and leading impact investors across Bangladesh.
