  • Sawyer "point zero two" bucket filter questions

    Im looking into bulk water filtration systems, preferably gravity fed. The Sawyer .02 micron 5 gallon bucket system is catching my eye. It has a stated .45 min filtering time and gets viruses as well as filtering. I like its ease of use and cleaning/priming. Dose anyone here have any hands on real world use with this system? Dose it truly only take .45 min for 5 gallons? I have looked at the "Cheaper then Crap" bucket filters and am unimpressed plus I have been burned by "CTD" in the distant past with purchases from them and the chinese crap they sold me, live and learn. Thanks for any input or help.
    This is the one I'm looking at:


    Thanks

    It has a stated .45 min filtering time and gets viruses as well as filtering...Does it truly only take .45 min for 5 gallons?
    First off, I do not own this model, nor would I...too much hype (like the 1,000,000 gal warranty) Even commercial ROPUs would have issues, with a filter that small, processing that volume before membrane failure.

    Not point four five minutes...forty-five minutes, as in almost ten minutes per gallon. This is going to quickly degrade with a .02 micron filter as it gets clogged in use...but will vary with the cleanliness of the incoming water. A prefilter is a requirement for any filter media this small.

    Unless you are going to be using this in a sterile clean room environment, you will get cross contamination into the "clean" reservoir. Sort of defeats the .02 micron aspect.

    Don't know what you consider "bulk" filtration, but in my book this isn't it. The finer the filtration, the slower water will pass given the same physical filter size. Are you thinking of supplying a household over an extended (months/years) time frame? If so, this would work for final filtration of drinking/cooking water...

    FWIW, we just use a Berkey with the black filters...been going strong for years, used daily.

    I truly hope this aids you!

      Thanks tech,
      This is the kind of info I'm looking for. Im kinda rushing my filter preps a bit, and price point shopping. looking at the amazon $121.00 Sawyer vs the big Berky's $365.00. I consider the berky the gold standard to achieve to. But like other purchases buy once pay once. Versus live and learn pay a couple times... If I had the funds a Berky would be purchased now. I just feel a push to get my water laid in. (I have bulk storage with no way to replenish "if" something happens.
      Here in central Fl. we will get one or two boil water alerts a year in my neighborhood for several different reasons, usually after the fact.
      Here in Florida our water has a lot of bugs in it, literal and figurative term. so I need a good 'bulk" filter. Im looking at this in a grid down or WROL water supply from nearby retention ponds/lakes/streams. I also plan on cisterns from the gutters on house which will need filtering. I have Katadine Hiker and a Hiker pro for backpacking and kayaking but no bulk way to produce filtered water for what I expect to be three adults over 40 and possible more. I figure gravity fed the best. "set it and forget it" type and low use of calories, to produce clean water. With little knowledge on this each scrap of info helps.

          Just a thought here. You can get two (or however many) Berkey filters, drill holes in a bucket to install the filters and essentially have a DIY filter for around a C-note. I'll have to double check, but IIRC the filters come with new seals and retainer rings...

            I got a katadyn ceradyn drip. I've run it daily for 5-+ years now.
            Does 10L at a time. Filters have a good life and its proven (I own a hiker ..mini...pocket as well) .
            Replacement elements aren't bad cost wise and if your smart can be Retro fitted into a homemade drip (most filters can anyway) .
            I got mine from jrh years back..
            Not a fan of berkeys or the Sawyer's ...the sawyers just have been to hyped up for their cost to believe they do what they are advertised as doing.

              we have two katadyns ourselves. the hiker and the vario. but have made our own bucket system like TECH is saying for the cost of the filters. we have tested it a few times and it works great, its slow but works. we just kept the top bucket full an keep draining the bottom one into a hold tank. and remember do not store wet filters, we let ours dry in the sun for several hrs before putting up.

                Dreamers- Gotta ask- why would you buy a hiker when a mini filter does more water for about the same price and no chemicals?

                    Its a great filter Robert but its very utilitarian in looks. We don't mind it that way. Because of durability. I did a review of mine a few years ago on YouTube where I smashed and beat on it..not something you'd wanna do on a steel body. I had one filter break.it was full of water. And when unpacking during our move my dad bumped into it. Te filter snapped at the thin point where it passes through to "drip ".
                    I run two elements on mine vs the three. Its fast enough IMHO like that. My water sources are very clean (not drainage ditch water) ..but I've only lightly cleaned them once I think...its been that long! LOL
                    It was a no brained for me since I had already been using their backpacking filters since 04'-+...so I knew I could trust them to work.

                      I like Katydyn as well, but I like the flexibility that Sawyer products give. For $20 on sale you can afford to put them in the car, on a BOB as a spare, on a last-ditch bag or an E&E setup. Add a piece of 3" PVC, a couple of caps, and you have the insurance in your BOB when you drop a ceramic filter while cleaning it. Maybe I just over-prep...I'm one of the silly ones that still uses Polar Pure... Regards, Templar

                          Yes carbon and the fact that the life is only around 200 or so gallons.

                          Mini filter- same price range, all ceramic and life span of up to 3,000 gallons.

                          Katadyn bought Pur in the early 2000's, that's where the hiker originally came from.
