Ping.
No haven’t tried those but looking into these:

My Berkey filtration system cost four times that, but is very reliable. The Berkey filters run $50 each, and we run 2 (capacity for four) that is claimed to be good for three thousand gallons. The filters are washable however, and samples tested after washing show great filtration even after three scrub cycles.
If these are legit I will purchase some for the stash...
I find that very difficult to believe.
Berkey doesn’t last that long and they are UNESCO approved for relief in disasters and third world.
I personally use the Lifesaver Bottle. It will deliver pure water for as much as 6,000 liters before needing replacement.
$200
What price do you want to pay for water that won’t make you sick?
I have never heard of that product, but this guy, Glenn Meder, has the best and most thorough knowledge of any expert I’ve ever heard. I attended a webinar of his last month and learned so much about all the different ways to purify water, what purifiers do NOT remove from water, etc.
This upcoming webinar is free,although towards the end Glenn will talk about his invention, a survival still for distilling water.

These are Sawyer filters. They are good at removing biological contaminants. They DO NOT filter out chemicals or heavy metals.
Look at the Aquacera Ceracarb. About $40 on Amazon. Doulton makes a similar one too. They both filter out everything.
Just, fiy, after I’ve done a bunch of research and discovery on water purification/filtration for the ‘prepared’ person...
Look into combining aggregate/charcoal on a home-built gravity rainwater filtration system. Unless you’re in a very dry climate, you want that ability first and it can be utilized secondarily for general water purification/filtration by manually getting the water to the top catch basin. You can find the designs on Youtube under ‘gravity water filtering’. IMHO, I would still purify the water before drinking (bird droppings being what they are).
Also fyi, the Berkey filters have a LOT more surface area for a similar price. I suppose it depends on what you’re putting them in (head pressure). The short/fat ones are more appropriate for 5gal bucket systems.
And since we’re on the subject, perhaps stating the obvious (or not)...bleach has a shelf life from the day of manufacture; don’t even think about storing it for emergency use. Stock up on powdered forms of water purification (calcium hypochlorite, iodine & the-like).
Anyone have knowledge of/experience with a good water filtration/desalination system?
I have trouble believing a claim like that.
If it’s fine enough of a filter to filter bacteria, etc., it’s going to filter particles. You can’t clean all those particles out each wash. They build up eventually.
I used an MSR Miniworks filter in a large swampy area. It cleaned the water fine and I drank it with no problems. But filling each Nalgene bottle required breaking down the filter and cleaning it off. That’s the double-edge sword of a fine filter. No way it would have gone as long as they claim if I’d been filtering only that type of water.
A million gallons of dirty water? Hard to believe.
A good water filter should also identify itself as a “water purifier” or “water purification systems”. A product cannot legally identify itself as a “water purifier” unless it has undergone rigorous 3rd party testing.
