Questions & Answers
Everything you see is depicted in a diagram. The filter and the hose each have their own reservoir. The only item missing is the optional carbon filter, which isn't required. If you decide to buy the carbon filter, keep in mind that it will significantly slow down the filtration process.
Because no consumer can reasonably measure the filter tube diameters, you'll have to rely on the manufacturer's data sheet for information on the filter fiber diameter. You'll also need to look into virus sizes to see if they can be blocked. But, as a user of this filter for twelve days on the trail, serving four people (48 total), I'll say this: days on the AT with no gastro-intestinal problems The filtering flow rate is incredibly fast, and there are no issues.
You could use it to filter salt water, but it would still be unfit for human consumption =)
The flexible tubing that emerges from the filter is connected to a screw-on connector. on the clean water bag's cap To get to the clean water, you simply unscrew it. So, the best way to unscrew the cap is to flip the clean bag upright with the cap pointing up. This product was used on a week-long kayaking trip in Canada as well as a 20-mile hike in Pennsylvania. It's without a doubt my favorite piece of equipment. Water filters quickly, and the entire system folds up and weighs next to nothing. The filtered water is comparable to any store-bought bottled water.
Selected User Reviews For Platypus GravityWorks High-Capacity Water Filter System for Group Camping and Emergency Preparedness, 4.0 Liter
Exceptionally useful! I did a lot of research on water filters before purchasing this. The fact that you can get a lot of water in one shot, that it filters FAST, and, most importantly, that it is portable sold me on it. PUMPING IS OFF THE TABLE! It's a no-brainer if you're backpacking. Water is 8 times heavier than air. A gallon of water weighs 3 pounds, and an adult requires about a gallon per day, so bringing water on a multi-day trip is a good idea. It is not possible to go on a day trip. At 13 ounces, it's a fraction of a pound. 6oz! In the long run, this will also save you money. The filter lasts 1500 liters (396 gallons), which is about $350-$400 if you buy gallons of water at the store. $400. Even if you fill from the tap, this saves space and eliminates the need to lug water around. br>br>While the other "straw" filters are useful, if you need to fill a Camelbak bladder or cook with water, you'll need a filter that can filter more water. The tubing and storage bags are of excellent quality and will not kink or deform when used. Because the hoses are long, you can hang the dirty bag from a branch while placing the clean bag on the ground for maximum filtering speed, or simply hang the clean bag from a lower branch. To dispense, simply detach the hose from the filter's clean side and hang the clean bag as shown in the image. br>br>Want to get the most out of a single water source visit? In fact, you can get up to 8 liters in a single shot! Simply fill the dirty bag with garbage and let it filter for 3 minutes. After that, disconnect the clean water bag from the hose and close it with the provided screw cap. Then, after removing the dirty bag, you'll have 4 liters ready to drink and another 4 that can be filtered quickly! That's 2. In a single trip, I was able to get 1 gallon! Cleaning: br>br>Cleaning: br>br>Cleaning: br>br>Cle br>When the dirty bag is nearly finished filtering (depending on water quality), simply lift the clean bag higher and back-up. flush for about 5 seconds, then clamp the hose and dump the water into the trash bag. To clean the dirty bag for a long time, fill it with 2 liters of clean water, a few drops of bleach, and filter it through. The dirty bag can be towel dried, but the clean bag should be hung in a dry place for a few days. Remove the bumpers and plastic end pieces from the filter and set it aside for a week to dry it out. br>br>Contrary to popular belief, there are a number of disadvantages to using this product. br>The filter is sophisticated, but it is delicate; it should not be dropped or used if the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius), as this will damage the filter. However, blowing air backwards through the filter is a simple way to test its integrity. If there are bubbles on the other side, the filter is broken; if there aren't, everything is fine. br>br>I absolutely adore this filter and am overjoyed with my purchase. I hope this review was beneficial to you!.
After using one on a trip with some friends who had section hiked the entire AT, I decided to purchase this one. They bypassed the "clean" bag entirely. The dirty bag and the filter were all they had. br>br>For a smaller group (e. g. , a two-person group), 3) It's probably a good idea to only carry the trash bag. In the case of a group of six people, The number ten makes sense, as does the clean bag. It enabled us to hang the clean bag to disperse water, which was particularly useful for cooking and washing. Why not give it a five-star rating?br>br>
- Instead of a bottom corner, the clean and dirty bags should be dispensed from the bottom center. Particularly the clean bag, because it would be easier to empty the clean bag.
- To stop the water flow, there was a handy clamp included. I'd prefer to have two of these, one on the clean side and the other on the dirty side, so that I could turn off the flow from the dirty side when the clean bag is disconnected. I could disconnect the dirty hose from the dirty bag to stop the flow, but in some situations, I'd rather not. br>br>Please keep in mind that this is only a filter and not a purifier. Bacteria, cysts, and spores are all handled, but viruses are not. That is fine for most surface water in the United States, but I would use a secondary chemical treatment if I was concerned about viruses.
The filter cartridge that came with mine was missing. Another reviewer seemed to be having the same issue. My father also has one, which we used on our most recent trip because mine was out of cartridges. He claims that on his first trip, it worked well and that he filtered nearly 20L through it. The filter was too clogged to be of much use on our trip. We back- Even after flushing it several times as instructed, it took 8 hours to fill 4 liters of water. Because it was quicker, we decided to boil water in a 2L kettle. I think this is a great idea, and if they get it right, I'd buy it, but for now, I'd pass.
The problem is that after only two days of use with my new filter, the plastic holes that hold the straps are almost completely disintegrating. Unfortunately, I was having a lot of fun with that filter. It would be very simple to devise a more powerful means of supporting it. br>br>update: br>br>update: br>br>update: I just spoke with customer service, who was very pleasant and said they would send me a replacement bag because it appeared to be a manufacturing defect.
The dirty bag has a ziplock so you can fill it with dirty water and then store it until you're ready to filter it. "Zip closed and then turn upside down to test," it says on the bag. I tried it, and the seal is shaky. With just a little pressure on the bag, it easily pops open. I'm not sure if this is a widespread issue or if I simply received a defective bag. I'll be back to replace what I've lost. I'll update my review if the replacement is satisfactory.
