MSR Guardian Gravity Water Purifer for Backcountry Use, Global Travel, and Emergency Preparedness

I bought this item for group trips in the Scottish highlands it works brilliantly

I've had the privilege of using this water filter on two extended camping trips, one with a single companion and the other with a group of four friends, where this filter served as our primary water source. Filtering an impressive 20-30 liters per day, this review reflects my extensive experience with this filter.Here's what makes it my favorite water filter and why it might be yours too:The Good:Exceptional Filtration: This filter boasts a remarkable filtration capability of 0.02 microns, surpassing most filters on the market by tenfold. It provides peace of mind by effectively removing even the tiniest contaminants.Effortless Purge Function: The user-friendly purge function is highly effective in restoring water flow. A quick and easy solution to maintain peak performance in the field.Swift Operation: With occasional use of the purge valve (around every 10 liters), the filter maintains a commendable fill rate. We effortlessly filled our 32-ounce bottles in just a matter of minutes.Generous Capacity: Holding up to 10 liters of water, this filter reduces the need for frequent trips to the water source, making it exceptionally convenient for groups and extended outings.Customizable Height: The filter's adjustable height is a thoughtful feature, allowing you to tailor it to your specific needs. Trimming the hoses for your typical scenarios is advisable, as they come quite long from the factory.Durability: This filter has proven to be more durable than expected, enduring the rigors of camping life.The Bad:Pricey Investment: It's worth noting that this filter comes with a relatively high price tag of around $300. While the cost may be a deterrent for some, it's important to consider the long-term benefits and warranty.Weight Considerations: Weighing approximately 1.25 pounds, this filter is on the heavier side compared to some alternatives. Keep this in mind if you prioritize lightweight gear for your trips.Durability Concerns: Although it has held up well so far, some concerns about potential tearing exist, especially when hanging 10 liters at a time. However, the filter is backed by a 3-year warranty, and MSR appears to be a reputable company known for supporting its customers.In Conclusion:For the "Good" reasons outlined above, this water filter has earned its place as a top choice in my camping gear. In regions like Hawaii, where there's a risk of diseases like leptospirosis, the ultra-fine filtration capability provides valuable protection. While the initial cost and weight are factors to consider, the filter's stellar performance and robust warranty make it a worthwhile investment. My primary concern is its long-term durability, but with MSR's track record and the flexibility of warranty coverage, I remain confident in this filter as my trusted companion for clean water in the wilderness.

The water tastes great and after a couple of times filtering the water, it is easy and handy to use. It is light to carry and will always be a part of my camping tools.

I lead outdoor education as a component of my professional life. Being able to generate this much potable water passively is a game changer. This is truly a massive technological leap forward in the field of water purification and is much better than similar competitors I have used. I look forward to seeing how durable this product is over the years. It has a lot of features that show how carefully considered its development was, and I suspect that durability won’t be an issue as it has already held up well over multiple backpacking trips and a couple thousand liters.

Filter Leistung ist hoffentlich gut,Was mir nicht gefällt die mindesthöhe wegen der Schlauchlänge, ich habe die Schläuche gekürzt wodurch er natürlich langsamer wird.Auch ist er nicht dicht egal wie oft ich die Öffnung Wickel,Der Abwasser bzw spülschlauch müsste weiter vom Frischwasser weg sein,Eine sinnvolle Befestigung der Schläuche fehlt auch.Besonders ärgerlich, der letzte Liter lässt sich nicht filtern weil die Anschlüsse zu hoch angebracht sind.Für den Preis maximal Mittelmaß

Best around…. Good tasting water… easy to rinse… must be stored moist is the only downside but that is because it’s so good (don’t want those 0.2 micron holes sticking close). See company website or pamphlet for specifics.
