Drink with confidence. Wherever you land.

Clean water shouldn't depend on local knowledge, language barriers, or a suitcase full of bottles.

The Klindrops straw filters bacteria, parasites, and microplastics down to 0.1 micron — and its activated carbon core reduces chlorine, so water tastes as clean as it is.

Questions

Everything people ask before their first trip.

How does Klindrops work? +

A multi-stage system: a PP pre-filter, activated carbon and a hollow-fibre ultrafiltration membrane. As you drink, water passes through each layer to help reduce sediment, bacteria, protozoan parasites and microplastics above the tested filtration threshold, while the carbon improves taste by reducing chlorine and unpleasant odours. No batteries, electricity or chemicals — place the filter into an appropriate freshwater source and drink through the mouthpiece.

Which water sources can I use it with? +

Appropriate freshwater sources: rivers and streams, lakes and natural springs, hotel taps, holiday rentals, public drinking fountains, campsites, festival refill stations and emergency water storage. Do not use with seawater, saltwater, industrial wastewater, sewage, or water that may contain toxic chemicals.

Does it remove viruses? +

Klindrops is designed to reduce bacteria and protozoan parasites using hollow-fibre ultrafiltration. Unless stated in verified laboratory documentation for this product, it should not be relied upon as a virus-removal device.

Does it remove heavy metals? +

No. The activated carbon helps improve taste and odour, but Klindrops is not a heavy-metal removal filter and should not be relied upon where heavy-metal contamination is suspected.

How do I clean and store it? +

Backflush the filter with clean water following the supplied instructions, shake out the excess, let it dry thoroughly, then store with both protective caps fitted in a cool, dry place. Regular cleaning maintains flow rate and prolongs filter life.

How long does it last? +

With proper cleaning and normal use, one filter is designed to provide 5,000 litres of portable filtration. Replace the filter when the flow rate becomes noticeably reduced — replacement filters are available on subscription.

Can children use it? +

Yes, under adult supervision — ideal for family holidays, camping, school trips and emergency kits. Children should always be supervised when collecting water and using the filter.

Does it need batteries or electricity? +

No. Klindrops works entirely by suction — no batteries, electricity or chemicals, which is what makes it ideal for travel, hiking, festivals and emergency preparedness.

What is the returns policy? +

If you're not completely satisfied, return it within 30 days of delivery for a refund in accordance with our Returns Policy. Fewer than 1% of customers claim the guarantee — full details on the Returns & Refunds page.
