Bangladesh faces one of the world's most critical water crises — a compound emergency of contamination, plastic waste, and preventable disease.
plastic bottles consumed every single day in Bangladesh
people suffer waterborne disease outbreaks every year
microplastic particles per liter of unfiltered water
for one plastic bottle to fully decompose in the environment
A premium reusable bottle with a built-in triple-layer hollow-fiber filter. No electricity. No cartridge refills every week. No single-use plastic. Just rigorously clean water — everywhere you go in Bangladesh and beyond.
Water clarifies as it descends through three precision-engineered stages — each eliminating progressively smaller threats.
The first barrier captures sediment, sand, rust, and large suspended particles. This dramatically extends the lifetime of the precision membranes below and maintains consistent flow rate.
The core innovation. Thousands of membranes create a filtration surface larger than a football field — physically blocking 99.9% of bacteria, protozoa, parasites, and microplastics with zero chemicals.
A final activated-carbon layer eliminates chlorine, heavy metals, volatile compounds, and odor. The result: water that isn't just safe — it tastes genuinely clean, every time.
Tap, river, pond — Hydra filters on the go. No infrastructure, no electricity, no waiting. Perfect for commutes, travel, and emergencies across Bangladesh.
At just ৳0.13 per liter, Hydra is far cheaper than bottled water. The ৳999 bottle pays for itself within weeks, saving thousands of taka every single year.
Lightweight, durable Tritan body with a carabiner clip. One bottle. Three thousand liters of clean water. A genuine companion for life.
Each Hydra replaces up to 6,000 single-use bottles. A measurable, lasting impact on Bangladesh's environment — from the first sip.
Hydra isn't just a product — it's a systemic answer to Bangladesh's interlinked water and plastic crises. One bottle, multiplied by a million people.
Hydra directly advances SDG 6 (Clean Water & Sanitation) and SDG 12 (Responsible Consumption & Production) — fully aligned with Bangladesh's 2030 climate and development commitments.
Conceived and engineered at Bangladesh University of Engineering and Technology, then independently validated across six divisions.
Be among the first 2,000 people to secure a Hydra. Waitlist members get priority access, a founder's discount, and a free replacement filter cartridge.
