Water Is Life: John DeYoung / Founder and CEO of Vivoblu
https://www3.nhk.or.jp/nhkworld/en/ondemand/video/2058994/
Former street kid John DeYoung, who developed easy-to-handle water purification filters, now delivers "water for life" to Ukraine as well as to developing countries. He explains his mission.

I love the compact sizeand easy use, and works better than the straws for camping and lasts longer. I tried this as we are looking to be more self sufficient. Much easier to use and you can bring the water source to you. Great for starting if you are looking to go off grid or to just be more self sufficient. Will probably buy several more of these to have on hand.

Excellent product, and great for when I am out on camping trips. The size of the water filter makes it easy to get water from a stream or lake and much easier than a straw filter. I love the flow rate of a gallon every two minutes, just using gravity, and it is very easy to clean, a definite plus! This is a great product that is great for all types of camping/hiking trips or when traveling in areas where you are concerned about the quality of the water. I'd recommend this to any hiker, runner, traveler, or backpacker.

A simple, multi use, minimalist, easy-to-use product. The product is lightweight and compact. It can easily fit into any camper’s or hiker’s backpack. Included in the kit is the water filter, 2 tubes, tap and wingnuts.

The package has instructions and configuration examples printed on the outside. They are very simple and require few tools.

There are different configurations that can be made with this filter. I attached the water filter to an empty coffee container. It was very simple to assemble and is one of the configuration examples shown on the packaging (see bucket example).

For campers or backpackers who need a water filter I would recommend this product for ease of use and weight. It could even be used for urban situations such as emergencies or breaking pipes.

The packaging claims it can remove quite a few bacteria, etc. It even claims to be able to remove the C19 virus.

We got two filter systems to add to our emergency prep kit because it can be installed into a water barrel, rain barrel or buckets. I didn’t even realize until I bought it that it can be used in a bunch of other ways, like a siphon from a bathtub or sucking water right from a river or pond. Tested it in our sink and it flows really fast, so it can definitely provide enough water for a whole family in a disaster/emergency. And I really like that it can be cleaned by hand just by swishing it and doesn’t need back flushing. I don’t want to have to rely on a backflush plunger tool when all chaos breaks loose, because if that thing breaks then your filter is worthless! Would definitely recommend adding this filter to your prep kit or go kit.

I bought this filter after hearing great things about it from friends, and this is my “go to” filter from now on. No more Lifestraw or Sawyer filters that break and clog so easily. This filter filters anything from murky lake water to camping & RV water sources into perfectly clear and crisp tasting drinking water. I was skeptical about buying this rugged water filter because of how different it looks from everything else in the market, but now that I have it, I don’t imagine ever going back to any other water filters.

My overall review would be that it lives up to its excellent reputation – it has very fast flow (I get a gallon of safe, clean water every 2 minutes), and is super easy to clean with the removable sleeve, so there is no more backwashing or using the “old syringe” method of cleaning! It also allows me to see the filter so I know it is clean with no broken membranes. It has an excellent design and it looks like the Company spent a lot of time making something really beautiful as well as functional. I also liked the Company showing me six ways to use this product from buckets to siphoning to camping water bags as well as using it directly from rivers (see image).
