The Versa Flow water filter is one of the lightest and most convenient personal water filters on the market. Weighing in at only 2 ounces you don’t have to worry about adding extra weight to your pack or try to find a dedicated spot for it. It will fit virtually anywhere. This water filter is perfect for backpacking, hiking, camping, travel, and emergency preparedness.


Although it is lightweight, it is heavy in features. Every filter is built to exacting standards and exceeds EPA standards for filtration. The Versa Flow has many tiny tubes called hollow fiber. Hollow fiber works through size exclusion. Meaning the hollow fiber tubes have thousands of tiny holes (0.1 microns) that block 99.999999% of harmful bacteria, and 99.999999% of Giardia, E. coli, protozoan cysts and Cryptosporidium. All of these organisms are too large to fit through the 0.1 micron holes. Some manufacturers filter the water through the core of the hollow fiber tubes, but this restricts water flow because only so much water can fit through the core opening. We filter water through the outside of the tubes by bending the hollow fiber. This dramatically increases the surface area and flow rate of the filter while protecting the filter integrity itself. If the core of the tubes become clogged from sediment on the competitors filter you can not use the filter. The Versa Flow allows you to be able to backflush the filter, clearing out all of the particulate and increasing the lifespan of the filter. If you consistently backflush the filter you can use it almost indefinitely. This means no additional filters, cartridges, pumps, iodine drops, or batteries to ever buy again.


The Activated Carbon module is made up of mixture of activated carbon and ion-exchange microbeads. Activated carbon adsorbs chemicals and heavy metals, and improves the taste and color of the contaminated water. The ion-exchange microbeads are an organic polymer substrate. These beads are porous, providing a large surface area for removing pollution, poisonous, and heavy metal iron from the water. The ion-exchange replaces these negative ions with innocuous ions, such as sodium and potassium.


Additionally, this combination will remove unhealthy organic compounds such as chlorine, pesticides, herbicides, gasoline, and diesel. The adsorption of these various compounds improves the taste and the color of water transforming it into the perfect way to refresh yourself while camping, traveling, or in an emergency situation.

    Better than...

    More versatile, lighter, smaller, and faster than a Sawyer. The versaflow is so much more superior, so glad I switched!

    Bought Versa Flow with Activated Carbon Filter just incase we would ever need it in case of emergency.

    Great product, even better customer...

    Posted by Jane Smith on May 26th 2022

    I wanted to have the product delivered in a specific timeframe, while I was in the US. It got lost on the way, so they sent me another one, overnight, free of charge. The filter is light, easy to use and efficient. Highly recommend!

    Great combination when taste...

    Posted by SoSmith on Mar 11th 2022

    I have used the Versa flow for a few years and loved it. Its performance has been better than similar style and size filters. The one downside in my opinion to all the hollow fiber membrane filters is that they don’t improve taste. Adding the activated carbon filter solves this issue. Using the activated carbon does slow the flow rate a little, but it is still faster than others that have activated carbon. What I like most about the combination, is if the activated carbon isn’t needed for taste or higher flow rate is important, then the activated carbon portion is easily removed.

    Love the flow rate of the Versaflow. The carbon filter just makes the water tastes better too. Bravo Hydroblu

    Posted by Daniel Farina on Dec 20th 2021

    I only recently received this unit, but it came without incident and was well-packaged. There is a window to inspect the filter that I like, and also it is one of the few units with a carbon filter add-on. Both the filter and replacement carbon filters are reasonably priced. I only wish that the carbon filters were somehow cheaper to ship, since they become microbial media quickly (if they are comparable to water bottle filters, they need continuous flushing or, for most of us doing sporadic trips, regular replacement).

    Water taste...

    Posted by Ed on Dec 10th 2021

    Haven't used mine yet. I bought this because I have used a friends and thought the water tasted better through it. Will be ready for spring this year. Also sent another to cousin now biking/hiking in Patagonia.

    Posted by Charles Goodin on Nov 14th 2021

    I really like the Versa Flow, especially with the carbon filter unit. They are the basis for my gravity filter systems (for myself and 4 adult children). I also use the carbon filter unit with my Sawyer Taps, which I use for attachment to kitchen faucets or outdoor hoses. In addition, I use Sidekicks for each person in the family (with additional carbon filters). All in all, this is the best overall system I have found (I've been working on this for years). Now to get a distiller... (I live in Hawaii and we're surrounded by salt water).
