The LifeStraw Max ($649.95, https://lifestraw.com/products/lifestraw-max) is LifeStraw's most advanced, high-capacity water purifier, engineered for scenarios where safe water access is critical—disaster response, remote communities, schools, institutions, and large groups. Using a two-stage system of 0.02-micron membrane ultrafiltration plus an advanced carbon filter, it removes 99.99% of viruses, 99.999999% of bacteria (E. coli, Salmonella), 99.999% of parasites (Giardia, Cryptosporidium), and 99.999% of microplastics, while the carbon stage reduces lead, chlorine, asbestos, and organic chemicals for improved taste.
The Max requires no electricity, batteries, or chemicals—only a pressurized water source (tap, pump, or gravity system with at least 1 bar/15 psi)—and can supply purified drinking water for up to 400 people per day at a flow rate of up to 3 liters/minute. The ultrafilter lasts up to 26,500 gallons (100,000 L); the carbon filter up to 4,000 gallons (15,000 L). It is tested to US EPA and NSF standards (NSF 53 for lead, NSF 42 for chlorine, US EPA/NSF P231 for microbial reduction) in an ISO-certified lab, with full lab reports published for transparency. The unit measures 20 x 15.9 x 13.3 in, weighs 15 lbs (7 kg), and is made of durable, BPA-free, FDA food-grade compliant materials.

"I haven’t used it yet, since it’s really part of an emergency kit for more people. I notice that the top on this unit is screwed down instead of clipped as in the instructions, which I expect is an update that hasn’t made it into the drawings yet. What I’d really like is some way to store the gray external tube securely and cleanly, clipped to or inside the main unit box. Right now it’s loose, which seems like an invitation to lose it."
"We get our water from a small well company. use to buy water from one of the big companies that delivered their water in plastic bottles… lifestraw max plus some glass bottles will pay for self in one year. Follow the easy instructions & the Max is amazing…in 15 minutes we got 8. 5 gallons of filtered water. tastes really good. the filters will last a really, really long time !"
"I had to cycle through three times before the water stopped having a bitter after-taste. It tastes good now, but I'm going to have it tested before I drink it. Until then, I'll continue to use my countertop container. I'll update after I get the water tested."
"I use the Lifestraw Max to filter lake water at my remote house in Alaska. The only water source is a nearby lake. The Lifestraw Max works amazingly well. Easy to use. Easy to clean. Easy to store. Produces great tasting water. I have the Max hooked up to a Seaflo electric pump and accumulator tank (pump runs 35-45 psi; tank is set to 32 psi). The pump provides pressure in the range recommended by Lifestraw. I am filtering from 7 gallon jug to 7 gallon jug. It takes 10 minutes for 7 gallons. The unit is fairly light and thus easy to set up when needed from a storage location. I highly recommend this filter."
"Nice compact package and user freindly!"
"I was amazed at how well it worked. thank you for a wonderful product"
"This unit was purchased for emergency preparedness for our local CERT team."
"Bought it for my parents , who live in Oaxaca , the water is from a well , they had been buying from a local water treatment plant but it tasted like chlorine, now they have water which tastes way better and they are not buying it anymore, we’ll worth the investment."
"This filter has been used in Haiti for nearly a year at a school with no issues. Extremely durable, lightweight to transport to its final destination, and it has a great flow rate. We have told countless other schools, clinics, and hospitals about this filter."
"This is the best filter I have used so far. It’s very easy and friendly to use once one learns how to use it. I very confident of the filtration systmem as it has the sieve and carbon filters which ensures the water is well filtered and safe to drink."
