Here is my Sawyer Mini gravity filter. I made special caps with quick connects that are valved https://www.freshwatersystems.com/p-...dy-14-npt.aspxIMG_6335.jpg
These replace all the caps on all my bottles. the silicone tubing is https://www.freshwatersystems.com/p-...16-od-x-1.aspx The 3/16 ID works better than the larger sizes others are using.
The system is almost a copy of the platypus system about 1 foot of tubing to the filter dirty side and about 4 feet of tubing with a hose clamp on the clean end.

One last thing to add is a small attachment that is used to shower with when clicked into a water bag.

If you go the bidet route it will click into a bottle

The whole kit it a little heavier than just using a mini, but a total weight of 8oz to have 4+liters of water carrying capacity, shower and a filter i'm ok with that.

The clean bag can be a hydration bladder which is what I actually do. I have a 1.5 liter Evernew bag with a DIY quick connect pickup straw. https://www.freshwatersystems.com/p-...ud-14-ptf.aspx with refrigerator ice maker water line connected to it. I locate it in a side pocket of my pack for easy access.
