Pond Water vs Water Filters (Berkey | Alexapure | Purewell)

How well do these gravity water filters actually filter water? Well, I put them to the test by running water from our duck pond, complete with mosquito larvae, through them to see if they could filter out the harmful bacteria.

Don't miss my video testing these same filters with some other fun contaminants: https://www.youtube.com/watch?v=cMfQMPxR1n0

Here are links to the 3 water filters I tested in this video.
