Platypus GravityWorks High-Capacity Water Filter System for Group Camping and Emergency Preparedness

Product Information

I’m afraid the filter is good but it doesn’t turn dirty (muddy/peaty) water into clean water by sight! Then depending on where the next water source was I’d fill the 1-litre reservoir and maybe my 500 ml one too, if it was a distance to hike. Yes, there’s not really much you need to do other than fill the reservoir, screw the filter on and turn upside-down, gravity does the rest for you! Effective: Every microfilter is individually tested to ensure it meets EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa**.

Sleek, lightweight, and thoughtfully designed, the newly minted LifeStraw Go Series filter bottle is ready for a rowdy road trip across Mexico, or a casual day on the river. Its streamlined, stylish design joins forces with a 0.2-micron filter and 4,000 L lifespan to deliver a hard-working portable filter that’s equally at home on trail, or around town.Filters also come in different styles: straw-style, pump filters, gravity filters, and UV or tablet treatments. They all make water safe to drink but differ slightly in size, durability, and price. The Katadyn BeFree system can filter smaller particles down to 0.1 microns. The majority of reviewers love that it’s both easy to use and clean. It’s not flawless, though. First, it isn’t as versatile as the Squeeze in that it won’t fit over standard water bottle mouths (this isn’t an issue if you plan to just use the included flask). Second, it tends to clog a little faster in filthy water than other filters, including the Squeeze. Effective: Each microfilter is individually tested to ensure it meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa*. Filters like the Sawyer Squeezeand Katadyn BeFreeare popular because the actual filter unit is so small, and the weight is close to nothing. The Sawyer Squeeze weighs just a couple of ounces, while the Katadyn weighs 6.8 ounces (but remember, it can filter up to 3 L of water at a time).

By using the Platypus reservoirs and soft flask by total weight for the water containers was about 200 grams, then with 3.5 litres of water (3.5 kg) the total weight was 3.7 kg. To justify taking anything on an extended thru-hike it needs to be dependable, lightweight, and durable enough to last for months of torture. Today, you usually see one of two popular filters being used by long-distance hikers going the length of trails like the PCT and AT: the Sawyer Squeeze or the Katadyn BeFree. Each day I would find the nearest water sources on the map, maybe a stream, spring or brook and few treat stops (pubs and cafes) where I could get tap water!If you’ve drank filtered peaty water depending on the colour of the water you can notice a slight soil taste, but it’s not something I’ve ever been bothered about, the darker the colour the stronger the taste of peat you’ll notice. The kit also includes a universal bottle adaptor. If you prefer to use a rigid bottle for your drinking water then the adaptor allows you to filter straight into it rather than the platy bottle that comes with the kit. The personal Peak Series filter worked extremely well and had a good flow rate. After 20+ years of LifeStraw being on market, it was nice to finally see a big upgrade in materials and design. Effective: Every microfilter is individually tested to ensure it meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa*. *This includes Giardia, Cryptosporidium, E. coli, Salmonella and Cholera.
