Emergency Survival Water Distiller and Gravity Filter Combination GRAVI-Stil Auto Fill Feature

I did my homework on this one and it has paid off. The quality of the components is immediately apparent. Everything is well thought out and engineered. You can tell the creators of this actually use their own product. With basically zero experience and average tap water in the condenser, I was easily producing 10 cups an hour right out of the gate.The included "instructions" are borderline worthless, however, and the Amazon listing really needs a makeover, but all you need to do is find their YouTube channel which has a newer assembly video for this model (not the video linked in the product description).I plan on using this to distill seawater in a survival scenario and I am very pleased with the initial results.

I purchased this as a means to provide potable water at a remote campsite, It will not make the trip. Here is my evaluation:As a gravity water filter; the water never did gravity feed. Employing the included hand pump produced small amounts of flow through the filter element but to maintain flow required almost constant pumping. A small aquarium aerator pump will achieve minimal flow through the filter element but do not exceed 11-15 inches H2O pressure or you just might blow the lid off.Incredibly inefficient as a distiller; the base tank transfers heat through the condenser (dog dish) and when the top tank reaches 160 F plus the steam just doesn't condense efficiently. There just isn't anywhere for the heat to go but up through the system. It needs more cooling in the condenser. When the system get hot, it produces a rubber smell in the distilled water, obviously from the gaskets/seals included.I did not waste the money for a water test. I would personally challenge any statements that water is potable after following the instructions, why not publish some evidence of that? All in all I would rate it just a little bit better than nothing. Wish I could get my money back. Does anyone know how to do that???

Function was lacking. Lost 40% of water due to steam. Looks good though

Well, its a nice water filter, if you use the gravity feed. I can say I'm sold on it distilling sea water, but I live in Arizona, so maybe when California splits off from the main shore it will fulfill my dreams lol. I would definitely like to use the cistern pump situation, as we do use cisterns and it would be nice to distill enough to fill a cistern. I use the hand pump for a cap for the top but it would be nice if it came with a little plastic cap. Or a screw on metal one. Or a size so I could get one.But it fulfills my gravity water needs. I can't use it for the customers, because they keep going to the top dirty water to fill a cup rather than the bottom lol. But I pour it into a restaurant style container, with a sealing lid and it prevents curious hands from breaking the filter stem.

UPDATE: This product went from 1 to 5 stars. After visiting the seller's website, I saw that they had improved the system, since I bought it. After contacting them, to ask if it would be possible to receive the improved float and straw, at a discounted price, they didn't hesitate to upgrade my system at no cost.I just received the package today. Not only did I receive the float and straw, but all new hardware, spigots and improved collection plate w/rubber gasket to prevent the rusting/peeling. Seller went FAR above and beyond what was asked. I should have contacted them before my initial 1 star review. They are quick to work with you, to make things right, or answer questions. This improved version is, now, absolutely worth every penny spent!Original Review: I've had this for about a year. It did not come with the storage bag, when I called to ask to have one sent, I was told they had stopped including them 6 months earlier. The lid between bottom pot, and collection plate started rusting/peeling after about the 4th use. As one reviewer said, you do need to frequently change the water in the top pot - for me the problem is more about it evaporating. Yes it gets very hot, but common sense should dictate you shouldn't be sticking your hand in there, or moving the device around while it's in use.I don't know if mine is the only one, but sometimes when I turn the stove on, and waiting for it to heat up, the unit starts rocking around VIOLENTLY, splashing water from the top all over the place. I have no clue why this happens, so I don't know what to do to prevent it, but I'd say that's a pretty hazardous malfunction.While I can look past the previous flaws, the main reason I bought this was to have water that doesn't taste like chlorine, or have other crap in it that doesn't belong there. I basically traded the taste of chlorine, for the the taste of plastic. I was new to water distillation, now I know better - never, never, NEVER use something that has plastic/rubber parts. The hose where the final product drips out from is made of a rubbery plastic. The final product is hot - the 'hot garden hose' reviewer was not exaggerating.The material quality of this product is not worth over $300. It should not have rusted right away (or ever, in my opinion), it shouldn't be wobbling, and most importantly it SHOULD NOT taste like plastic for that kind of money. You can NOT send it back for a refund, exchange, or credit towards a different product if you use it even once. If you're unhappy with it, after it's first use, you basically just threw $350 down the toilet.Still outta money for a better product, and very disappointed.

I am very disappointed from this product ( I don't know who give it five star reviews ? ) I used it for over two hours to try to distill water , had to change cold water in the top pot every half an hour to keep steam condensing and end up with only 3 quarts of distilled water. Water had strong rubber like odor because black gasket on the bottom of condenser pan. For me it is very inefficient and also takes so much time and water to operate it I don't recommend it for any one . Also they will charge you 50% restacking when you return it .

Nice quality stainless easy to use without having to take apart to refill boiling pot! Great customer service used it three times for distilling water! I own a Berky filter but this does both filter and be used as a distiller.

High quality product. I use it daily for filtering drinking water. Haven't tried desalinating with it yet but like it's desalinator design.
