Lifestraw Peak Series - Collapsible Squeeze Bottle Water Filter System 650ml for Trail Running, Through Hiking, Travel, Cycling, and Fishing (Dark Mountain Gray), Tritan

Key Highlights - Premium, superior-grade TPU — highly durable, feather-light (105 g), and ultra-compact (rolls up tiny) 0.2-micron filter: removes 99.999999% bacteria, 99.999% parasites, microplastics, silt & turbidity Extremely fast flow, almost no clogging even in muddy water, super-easy 30-sec backflush No virus protection (not needed for my Indian hill + domestic travel use) Why it’s my daily carry - Universal 28 mm thread fits every Indian PET bottle (Bisleri, Kinley, Rail Neer, etc.) I use the filter screwed onto cheap 1–2 L plastic bottles and keep the collapsible TPU just for scooping or backup Perfect for hiking, trains, buses, hostels — I’ve completely quit buying bottled water Buying experience & one big gripe (India prices) - Paid ₹2,000 for the 650 ml. The 1 L version costs ₹9,000–10,000. Weight and packed-size difference is literally negligible (15 g). Honestly, I wish LifeStraw (or Indian sellers) would just discontinue the 650 ml and drop the 1 L price to ₹3,500–4,000. Same materials, same filter, same performance — charging 5× more for 350 ml extra capacity feels greedy. Bottom line - Best lightweight, durable, universal squeeze filter in India right now. Buy the 650 ml if you’re budget-conscious (it’s still fantastic value at ₹2k). If you can stretch, get the 1 L — you’ll thank yourself every time you fill up. LifeStraw, please kill the 650 ml and make the 1 L affordable!

Very good product. Used for two international trips and many treks. Still working fine.

Works great, used it in a trek totally satisfied

The product is excellent for great Water Filteration on the go. And the seller Great Rocksport is also very Good. I want to bring to notice to anyone buying this, that the product comes in a cardboard stand which does not fully cover the product, but a good Bubble Wrap is provided. Also to note that there is a slight dot sized dent at the bottom of the plastic body of the product, and this comes from manufacturing in all the units, so don't be bothered by it. I had a doubt about this, and so I contacted the seller and also ordered a replacement. I received the replaced product with good cooperation from the Seller Great RockSport. And also there's a Charity work to provide clean water to the unpriviledged with every purchase. Thank you everyone.

This product is no good. I bought it only because CNN traveller praised it liberally. After a week, the bottle started leaking from the bottom. I carried it in my duffel bag, found water in the bag; investigated and found that it was leaking from the bottom. The joint at the bottom developed a small hole. Currency notes, my credit cards and clothes were given a free shower by this leaking bottle. I am going to ask Amazon to refund my money! DON ‘T BUY THIS!

Love the Lifestraw series of filters. I have almost all of them. The original one that I bought 4 years ago, the one in the bottle, the metal one and now this. the problem I faced with this one is that there were no instructions on how to attach it to a regular 500ml to 1 litre bottle. I kept on trying to pull out that end that has the cap, while all I needed to do was to unscrew it clockwise and anti-clockwise to put it back on. I thought it needed some attachment that I might need to buy separately. What the packaging lacked was a simple arrow or words that said (unscrew cap to attach on bottle). Also, why Flavor stars in the rating system?

The bottle has excellent quality. But a major problem is that inceonce the water becomes less, it does not flow out easily and you have to arch your head and back like crazy to get the water! The quantity is small, and one fourth of the water at the bottom is nit easily drinkable

Good product, filtered well, not sure of the quality of water filtered.
