Royce: " Thanks Royce! I'll swap those around. It makes complete sense now that you mention it. |

I've used the Katadyn basecamp system converted to use with the Sawyer personal water bottle filter and it works fabulous. I've found that after setting it up, I allow the dirty water hose to run into the filter for just a moment before connecting it. Otherwise it is slow to flow. I find the flow to be great. Fills a liter bottle in 20-30 seconds at most. Never really timed it. Normally don't backflush, but sometimes just for fun since it only takes a few seconds. Pikechase... If you reversed your dirty and clean water lines, the flow would improve. The length of line after the filter doesn't affect the flow rate. The length before does. Longer = Better According to Sawyers flow rate report, the flow rate is determined by head pressure, altitute and the cleanliness of the filter. The head pressure is the distance from the top of the water to the filter. For example, if your head pressure is 14 inches the flow rate would be an estimated 10 gallons per hour. If the head pressure is 42 inches, the flow rate would just about double to 19 gallons per hour. |

When the mini no longer backflushes well, I'll upgrade to a squeeze. |

When you start filtering, squeeze all the air out of the bottom bag, then make sure to get all the air out of the tubing so you have as much water column as possible pulling water through the filter. I do not think it matters if the tubing is above or below the filter as long as you get all the air out of the tubing. I have two 2L Platypus bags to swap out on the bottom. This system worked ok for three guys. For a big group, I use a 5 gal bucket on the top, tubing from the bucket to a Sawyer mini, tubing from the Sawyer mini to a 3 gallon Coleman collapsible water jug. I down sized the tubing so I can work it into the spout on the Coleman jug. Here again, make sure you get all the air out of the tubing above and below the filter. |

THEGrandRapids: "I ended up getting the Sawyer All in One- which appears to be the squeeze but with different attachments. I also picked up a 10L HydroBlu Go Flow gravity bag on amazon. I also have a 2L camelbak I was going to use for the dirty water side but wanted more capacity. I will report back on the HydroBlu bag- anyone else use it? Headed somewhere next week- either near Atikokan or end of Gunflint. " Where do you go by Atikokan? |

proepro: " I bought one of these for my clean water container. It worked well and packed up small. It never leaked (we were base camping not transporting water in it.) I have used the Sawyer Squeeze bags and Platypus bottles for dirty water bags, but hard to fill the small openings. A Platypus 2L (there's also a 4L, I think) dirty water bag from their gravity system is easier with the zip top. I have seen YouTube videos of people using a cut off water bottle. I have used my Sawyer Water Bottle to fill their Squeeze bags - works better than trying to dip them in the lake. |

The squeeze is the same 0.1 micron, but a little bigger. The 3-way looks to be basically a squeeze-type filter with options unnecessary for our purposes. The purification filter is a 0.02 micron filter. Mini's and squeezes are the most popular for gravity setups. I use a purification filter followed by a Katadyn carbon cartridge in my setup. |

Here is a pic I took of a few different units I have. From left to right: Sawyer purification filter, Sawyer full size, Platypus full size, Sawyer Mini (I think, again came in the blue water bottles) , Platypus Carbon |

Ragged: "The one I have 1000+ gallons through was out of a water bottle setup, well before the mini and squeeze type rigs came out. It’s probably considered full size. We have the Sawyer large attached to the Sawyer 4L bag with 3 feet of hose. Worked fantastic for 5 days last weekend for group of 4. Love it. CB |

andym: "We use the full size Sawyer filter in a DIY system based on some MSR bags and various parts and hoses, some of which came from the hardware store. It works great and filters a 4 liter bag in a few minutes." Same here 11 years and running |

Which filter do you actually have? Their website shows a number of filters that can be used (and maybe some are new and thus the confusion when going from old threads on the topic to their website)- the 1 gallon gravity, the mini filter inline (assuming a DIY), the All in One Filtration System, 3 way inline water filter, and Water Purify Bucket System. The website doesn't specify very clearly what the difference is in all of these. I'm assuming filter size and, other than by looking at the photos, I can't tell if one is bigger than the other. For the Sawyer fans, which one do you use for your gravity system? Half my trips are with my wife and the other half there are generally four people total. I'm looking for more water production and less concerned with ultra-light weight. |

Smartbottle They show it used as a dirty water also but I am not sure how to fill it. What do yall use for the dirty water bags? I have seen posts here abou modifying dry bags but what about off the shelf options? |

HayRiverDrifter: We are picking up our new canoe in Atikokan, so we may put in at Batchewaung via Nym for a few days. I haven't been up there before. |
