Which one actually worked? (gross pond test)

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.

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

Thanks for the time and effort to make this video available to us. I've been retired for quite a few years so my knowledge on this topic may be "old school" to many of you. My profession was environmental chemistry and water pollution control systems design. In all of the reviews I have read here on youtube the creator of the video focuses on the brand name of the filtration device as though it is the most important part of the testing. In most cases, the manufacturer of these filtration units simply makes two metal cans that fit together, a lid, a spigot or faucet, and fittings to attach the filter(s). The actual filters are usually made by another company and sold to the device company to be installed in their product. In many cases the actual filters are all manufactured by the same company and installed in several different brands of filtration units. That's why the same filters can usually be installed in different brands. So the "tin can" that sits on the counter and looks nice and shiny plays absolutely no part in removing contaminants from the water no mater what brand name is displayed. I'm sure many of you already know this but some of the questions and comments indicate that this is not true for everyone. 😊

They say to filter pond/creek/river water thru a tshirt first, get the chunks and debris out. Then thru the Berkey.

I looked at Purewell as part of my filtration research, and I came to the conclusion that Purewell focuses more on removal of biological contaminants, as opposed to removal of chemical and organic agents. I have chosen Purewell filters as part of my filtration program, but I also have a method of prefiltration through multiple charcoal activated filters before utilizing the Purewell candle filters. Finally, I have a Sawyer MINI threaded onto a spigot tap as final filtration layer. My maximum total of layers for emergency filtration is 5 layers. In the field, I use three layers of filtration.

I like your test! I had my pond tested at the local college cost me $100 for their most thorough test. Stumbled across a good deal on the Alexapure setup you have and saw an amazing difference. My biggest worry being some of the excessive minerals sulfates, nitrite, nitrate, ecoli. Chloride dropped by 30.176 to 1.83 on scale. Ecoli went from 66 to <1.

Answers a lot of my questions, good job…thank you! I have the ALEXAPURE, by the way.

This is the best water filtration video I have ever seen. I have the Alexapure and love it . Thank you!

Thanks for taking the time and money to run these tests, very good content 👍

Thanks for the video ! Good Job !!! At our cabin we drink water out of the lake after boiling for 20 minutes and then running it through a Berkey that was given to us but not with Berkey's filter cartridges. The lake water is tested periodically for about 30 different contaminants. I never thought much of Berkey's refusal to do any 3rd party testing and NSF certifications. I don't trust a business that says: "Just trust us, we wouldn't screw you."

I went with a Pro One water filter system which looks the other models you tested. Pro One has independent lab testing to back up their claims of filtration and when you read the vast listing it's a no brainer. A drip water filter system is a great item to have in reserve, just in case you need another clean water source. Great testing !!

great test! I would love to see more tests with the water filters!

[cherylperkins]

Thank you for this. Years ago, before I know what I know now, I bought an Alexa Pure. So glad I did not buy a Berky.

Well done on your testing. Something to consider when looking to buy is the expense of filters and how often they should be changed. I have a Travel Berkey that gets new filters every 5 years. I am glad to see other products on the market and also to see them perform equally under basic testing. Thank you for running this comparison.

Great video! I’m looking forward to more! Since this one that I’m watching is four months old I’m sure you have some newer ones I’m going to look for them. I also subscribed. Thank you so much for taking the time, energy and money to do this most important video!I’m trying to decide what water system I want to buy for our home!

I've had my Berkey for about 10 years and it is still going strong. They say that the filter is good as long as it passes water through it, and it still does. Replacing the filters has gotten so expensive that if I feel I need to replace them, I probably will go with these other brands.

Would love to see you push these filters to the limit. Considering there price I hope they can live up to all of their claims. Thanks for the time you took making this video.

[JD-uyjs]

Thanks was about to buy those test kits and do this for myself. Saved me money.

[lukelucy]

I forgot to thank you for your time, Great Video thank you.

[brendaallen]

Live in Arizona, extremely hard water, but with 2 black & 2 fluoride filters our Berkey has been great for the 4 years we've used it. Great video. Thanks.

[markguice]

Great video! Thank you for taking the time to test them!!!

Vwry aqesome tests! I wasnt even aware these filters existed.
