Replacement & care
Replace it when your filter is damaged, stays blocked after cleaning, has frozen after use, or reaches 2,000 liters.
Fitting: unscrew the cap, detach the old cartridge and connect the new one firmly to the straw under the mouthpiece. Rinse it with clean water only, fill the bottle, then take a few firm sips and spit them out to prime it. The first sips take a little effort.
Care: never use soap, detergent, bleach, boiling water or a dishwasher on the filter, and do not let a used filter freeze. Need help checking the fit? Contact the Hydra team.

Tested at BUET.
Made for your everyday.
HYDRA’s filter is BUET tested for 99% removal of bacteria, parasites and microplastics. The same removal specification applies to HYDRA and HYDRA Lite.
Questions about testing? Talk to usA few things
worth knowing.
Does it need electricity?
No. Water moves through the built-in filter as you drink. There’s no battery to charge.
How much water can one filter handle?
HYDRA specifies up to 2,000 liters of filtration capacity per cartridge. Contact our team for replacement and care guidance for your bottle.
Does 99% removal mean it removes everything?
No. The 99% figure covers bacteria, parasites and microplastics. The bacteria and parasite claims are certified by BUET’s Bureau of Research, Testing and Consultation (BRTC); microplastic removal was tested in BUET laboratories. It does not remove arsenic, viruses or salt. Use it with tap water, flowing river water, or a fountain or waterfall — never seawater, and not tube-well groundwater, where arsenic is a known risk in parts of Bangladesh.
Where can I see the water flow?
