## Overview

The LifeStraw Family 1.0 is a gravity-powered portable water purifier featuring ultrafine 0.02 micron hollow fiber membranes that remove 99.9999% of bacteria, 99.99% of viruses, and 99.9% of protozoan cysts. It purifies up to 18,000 liters (4755 gallons) of water without chemicals, providing safe drinking water for a family of four for up to 3 years. Lightweight and durable, it requires no electricity or pumps, making it ideal for emergency preparedness, camping, and travel.

## Description

The key distinction between membrane microfilters and membrane ultrafilters lies in their pore size. LifeStraw's membrane ultrafilter, for instance, has pores as small as 0.02 micron, which is ten times smaller than those of a membrane microfilter. Clean water passes through the membranes' pores, ensuring the water is microbiologically safe for drinking. However, due to their smaller pore size, ultrafilters may have a slower flow rate or require more pressure for water purification compared to microfilters.

Review: Excellent water filter, great value! - We took this water filter with us to Zimbabwe, six months ago. Although we were able to buy bottled water, we had this as a back-up. We filtered water every day, from a nearby well, to use for washing dishes (I still boiled the water first, but that was probably over-zealousness on my part!), for washing clothes by hand and other non-drinking uses. We were truly pleased with this product and have recommended it to many people. We appreciated that it is very lightweight and portable, and it was so easy to use. I did learn that it's important to have the unit hung high enough (per the clear directions), so the hose is straight and taking full advantage of gravity. The production is slow, but if everyone in your party adds water to the chamber whenever they think of it, you'll be fine for everyday uses. I did drink the filtered water a few times and did not have any ill effects. The water we were filtering was coming from a residential (city) well, and you could see dirt in it, sometimes. If you are thinking of taking a gift to a local resident living in a situation where water is scarce and not treated, this could be a life-changer. Highly recommended product!
Review: Great Product - Produces microbe-free water that is also free of micro-plastic particles found in all brands of bottled water. Time will tell how harmful those particles are. I filter my algae-laden well water thru a 1 micron sediment filter and two 10" 1 micron charcoal filters before it's poured into Lifestraw bucket. Collect in glass and stainless steel containers. Live alone, so slowness is not a problem & 0.02micron pore size provides the safest water you can produce. desertcart price much lower than factory-direct.

### ⭐⭐⭐⭐⭐ Best value
*by C***X on August 31, 2020*

I haven't opened or used this yet but I've purchased other Lifestraw products in the past. The only negative I know of and read from other reviewers is that once you open the bag there is no storage case for the unit and it's pieces so, before I open it I'm going to find a plastic tool case or something to use to store it in. The reason I'm writing this review now is to get the word out about Lifestraw. This is the second best unit I know of. It filters 4,755 gallons of water down to 0.02 microns which is enough to filter out viruses and bacteria etc. The absolute best filter I found (the Survivor Filter PRO) was twice as good bc it went down to 0.01 microns and did like 25,000 gallons or something and they both cost about the same. The reason I chose Lifestraw is because it's gravity fed and you can hook up a large water bladder or tank etc to it to feed it... The 0.02 micron level is way good, much better in fact than most water filters sold (which are generally rated at 0.20 microns) and so safe to use and have sold like 5 million units worldwide. The Survivor Filter PRO's .01 micron filter has to be hand pumped 50 times to get a 500ml (about a pint) little water bottle full of water and it uses multiple filters that need replacing etc. There is no way I could see the tiny looking hand pump lasting long enough to pump 100,000 liters. That comes out to 379 pumps for one gallon of water. 100,000L's = 10,000,000 pumps. Wow! The pump in the picture looks plastic but I seriously doubt that if it was metal and with ball or roller bearings, that it will last that many pumps, lol. But seriously, I don't see myself pumping this thing 50 times every hour to get some safe water. I'd rather just dump some water in the feed hopper (my words for it) and come back in an hour and get 2.4 to 3.2 gallons of purified water. That's an average of 2.8 gallons of water in an hour with no work, no pumping.
