DIY Low Cost Gravity Water Filter for Hiking and Backpacking

I normally use a Saywer Squeeze system to filter my water when I am out hiking and backpacking. If you have ever used one, you know that filling the bag that comes with it is next to impossible. I know most folks use a cut off bottle to do it. But then when you do finally get it filled you have to awkwardly fill your clean bottle in the weirdest of positions. I wanted something easy to fill that I could just let gravity do the work so that is why I did some research on YouTube and found a system I liked. In this video, I show you how to make one for yourself using a filter and bag you can get on Amazon. The filter is called a hyrdoblu and I tested it fully this weekend and it works great. The flow rate is acceptable and filling up the bag is very easy no matter what kind of water source you are using. The best part of it is that the filter is relatively cheap on amazon. You can find it here:

You could also use a dry bag of whatever size you like, for instance in the video I am using a 2L dry bag, but you could use a larger one for group camping. Here is an example of one that comes in many sizes:
