![]() Flip the reservoir upside down so the bottom of the filter (dirty side) is in contact with air inside the empty reservoir.Filter approximately half of the water through the cartridge.Fill your reservoir with 1L of water, and attach it to the dirty side of the cartridge.I feel like I need to intentionally break a filter to test this, but according to the instructions provided by Platypus, you can test the filter by following the following steps. If you fear that the hollow fiber membrane of your filter has been damaged due to freezing temperatures or a drop, you can test your filter to check whether it’s still going to be delivering you clean drinking water. Lastly, the Platypus QuickDraw can be tested for integrity. This is not, however, an issue with the Platypus QuickDraw (as far as I am aware). Tightening the Squeeze too tightly on a water bottle can damage the O-ring and cause the filter to leak when filtering (or so they say). This may be a bit of a hiker misinformation, but I’ve always been under the impression that you should not tighten a Sawyer Squeeze too tightly on water bottles because the water bottle threads are deeper than those on the bags Sawyer provides. In my personal experience, this all becomes basically trash. The Sawyer Squeeze comes with two Sawyer bags (with caps), a mesh bag, inline filter attachments, an extra o-ring, and a plunger for backflushing. You can purchase a version that includes a dirty water reservoir, but other than the user guide, that’s everything in the box. Something not apparent from the table above – but something I consider to be a strength of the QuickDraw – is that the QuickDraw filter comes with just that, the filter. ![]() However, the bottom cap is a much more elegant solution than carrying around a water-soaked bag for nighttime storage. With the Sawyer, my solution for this is to put the Sawyer into a plastic bag before it goes into my sleeping bag. With the QuickDraw, the bottom cap means I don’t need to worry about residual water leaking into my bag at night. Typically, I keep my filter attached to a water bottle, but when I need to make sure it doesn’t freeze during the night, I put it in my sleeping bag. If you’re interested in learning more about the intricacies of these percentages, MSR has an informative post on the subject.Īnother advantage to the QuickDraw is the included (removable) bottom cap (which weighs 0.2 oz / 6 g). But I would assume that this difference wouldn’t make a difference in the overall risk to your health since both products meet the EPA (Environmental Protection Agency) and NSF (National Sanitation Foundation) standards for drinking water. How much difference with the extra 0.0999% of protozoa and 0.00009% of bacteria present in water filtered by the QuickDraw make? I have no idea. The Platypus QuickDraw removes 99.9% of protozoa (that’s three fewer 9s) and 99.9999% of bacteria (one fewer 9). This translates into the Sawyer Squeeze removing 99.9999% of protozoa and 99.99999% of bacteria. This can also be expressed as one-thousandth of a millimeter (0.001 mm), or approximately 0.000039 in. A micrometer is one-millionth of a meter (1×10 −6). What’s a micron? It’s a micrometer – yes, the metric system, America. If you were paying close attention to the table above, you may have noted that the Sawyer Squeeze has a filter pore size of 0.1 microns vs the QuickDraw’s 0.2 microns. The Platypus QuickDraw can either be shaken back and forth (in clean water) or you can press a bottle tight against the top of the QuickDraw and force water through in reverse (similar to using a sport cap with the Squeeze). The Sawyer Squeeze comes with a plunger for backflushing but it can also be attached to a sport cap (the nozzles that some Smartwater, LIFEWTR, and likely other store-bought water bottles come with) and backflushed once you remove the Squeeze’s white cap. They are nearly identical in size and circumference, but the Sawyer Squeeze is slightly longer and girthier than the Platypus QuickDraw.īoth the Squeeze and the QuickDraw can be backflushed in the field. They both can be attached to external reservoirs to filter dirty water and they’re both compatible with most store-bought 28mm PET soda/water bottles (e.g. The Platypus QuickDraw and the Sawyer Squeeze are both exceptionally lightweight hollow-fiber membrane water filters with ABS plastic housings that remove bacteria and protozoa (e.g. Shake or any flexible water bottle w/ 28mm opening Best Ultralight Freestanding 1-Person Tents.
