Took to Costa Rica - Best way to provide large volumes of water when traveling

"We are a family of five (2 adults and 3 kids) and took the 8L gravity filter with 8L storage bag on a trip to Costa Rica. We also had bottle filters (LifeStraw Go Series) for each person. We drank water exclusively from our bottles or from the 8L gravity filter. We did not get sick the entire trip and we always had enough water. The 8L bag was plenty of water for us to keep in the hotel room or to bring around with us in the rental car on all our adventures. The bag is very heavy duty and perfect for travel but probably too heavy for backpacking. I would bring a lighter weight product if I was backpacking. We hung the bags on doors or hooks in our hotel rooms and never had an issue finding a place for the gravity filter. We found that hanging the filter bag on the top of a door with the storage bag hanging from the door knob below was the perfect setup. We consumed more water directly from our filtered water bottles (LifeStraw Go Series 1L and 22 oz) but it was really nice to have a large volume of filtered water ready to go at all times. When we were hiking around in Costa Rica's national parks or traveling from beach to beach, it was extremely helpful to have a huge bag of filtered water to refill our water bottles. We did not buy any water the ENTIRE trip. Not many travelers to Costa Rica can say that, or to any other country. Bottled water is expensive in Costa Rica and we estimate we saved about $350 over the course of 8 days in Costa Rica, not to mention avoiding all the plastic bottles and trash. The 8L gravity filter and the water bottles certainly paid themselves off! We purchased our 8L Peak Series gravity filter directly from LifeStraw. This gravity filter and the water bottles will join us on all future trips. I highly recommend."

Fast, then slow

"Bottom line: filters but does so slowly. So far I've used this filter for a 6+ day canoe trip and a 3 day canoe trip. The first time I used it to filter 8L the flow rate was pretty good, and it filled the clean bladder within the advertised time. But the second time I filtered 8L the flow rate reduced to a trickle. I tried back flushing the filter but didn't notice an improvement in flow rate. After getting home, I couldn't get the filter to return to the fast flow I experienced the first time I used it. Assuming some error on my part or the product, I ordered another filter but had a similar experience (the first filtration was quick, but the flow rate slowed way down during subsequent filters). Back flushing seemed to improve the flow marginally but the clean bladder was still taking 60+ minutes to fill. The water I'm filtering isn't murky. 3 stars because if you're patient enough and have the time, this filter will get the job done, it's tough, and well-designed to carry."

Tough enough

"The peak gravity filter system is well made and looks tough enough to withstand plenty of use. Haven't had it out on the trail yet but it' will be the perfect size for our family."

Close to perfection but that's all you need!

"BLUF ( Bottom Line Up Front): This is more than just a filtration system you take on a glamping trip. It serves several purposes that ALL can benefit from. Durable, efficient, versatile, and compact, you can keep this stored in your vehicle for emergency purposes, in your pack, and the pantry. You'd never have an excuse for not having clean water with this Filtration system. I've taken the new 8L Lifestraw Peak series Gravity filtration system on several different types of outdoor excursions. From glamping to Overlanding, day hikes to multiday mountaineering objectives, casual bike rides to backpacking, and even padel boarding. This product lives up to what Lifestraw advertises: Enhanced microfilter performance - meaning better performance against sand and silt and maintaining great flow over the long haul. It held up fine while collecting and filtering waters from lakes and glacier water. However, compared to Lifestraws competitors, the water flowing through the filter was slightly slower. But it never dwindled or slowed. Filtration was consistent throughout my testing. Ultra-compact - our filters are removable and re-configurable for ultimate packing flexibility. True and confirmed. I've managed to shove this system into a mid-size bike packing storage compartment on one side and filter/cap on the other. Ounces are pounds, and pounds are pain from a mountaineering/hikers perspective. This system can be packed down into the brain of a pack, side pockets, and even be thrown inside a pack, taking VERY little space, if any. Highly versatile - these systems were designed to be interchangeable and feature universal threading and connectors to make them as adaptable as possible to all your gear. I didn't have the pleasure of testing this out properly. But I can say that in a crunch, you can use this as a tried and true Lifestraw Peak Series Personal Water Filter Straw. The filtration system is small enough to fit through a Gatorade bottle; seal the exposed areas with duct/gorilla tape, and you have a Lifestraw Go bottle (sort-of-ish). Extreme durability - tougher, thicker, premium materials that won't puncture, tear, rip, crack, or burst. This couldn't be any more true than the words they used! I've had this attached to the outside of my pack (empty) while rock climbing and bushwhacking, with no tears, rips, or cracks. At base camp, top it off with good old glacier stream water, drop it on rocks, and it kept filtering, hydrating and providing clean water for dehydrated food."

Durable and good tasting

"Lifestraw gave me this item to test for free. I used it while camping just outside of the boundary waters canoe area with a group of folks. Pros: Super durable. Large capacity. Water flows out at a good rate. Tastes better than any of the other water we drank. Areas for improvement: Was hard to fill the reservoir with lake water. Need a little carrying case for the backwash and plug so you don’t lose them. Overall, I’m super impressed with the quality of this product. It’s great for group camping in areas where there’s no reliable drinking water. I’ll definitely be using this again, many times."

Great for camping

"I used this in a two day horsepack and it worked great. The flow never dwindled and I loved the sturdiness of it"
