Thanks to Brian who tipped us off this past week about Sawyer Bucket Filter Systems. It apparently is powerful enough to filter out bacteria and viruses, almost never needs filter replaced (1 million gallons!), can filter over 150 gallons a day and has a crazy high filtration rate:
5.5 log for viruses = 99.9997% filtration rate
6 log for for protozoa like Giardia = 99.9999% filtration rate
7 log for bacteria like salmonella, cholera, E. coli = 99.99999%
It’s $142.95 for the more powerful viral filter, and $59.95 for the biological one. Learn more at…

Thanks again for the tip, Brian — at TRAIN International.
Been selling these for missions application ever since I found them at the global health conference about 5 us ago. Excellent product. They offer independent test results. They just come out with Mini version of The bacterial version. Howard Lisech
We at GAiN International have used this Sawyer Water Filter for the past few years in such places as Zambia, where my wife and I led a team in 2013 and, working alongside are in-country partners, distributed the filter systems to more than 400 family units. They are as good as they claim.
I bought one of these on our most recent trip to the US. Sadly, I found the hype to be too good to be true. We live in a small city in central Africa. Our city water has a lot of sediment and rust in the water. Previously I had used very simple ceramic filters manufactured in Nigeria, but wanted something higher quality, efficient against bacteria as well. The sawyer filter worked great for the first day or two. When it slowed down, I back flushed it as per the instructions on their website. It improved, but soon the filtered water had the same orange color as the unfiltered water. within a week or two, even with repeated backflushing, the flow had slowed down so much, I couldn’t justify the bucket taking up space in my kitchen. In my opinion, complete waste of money.
