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 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

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

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

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."

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

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!

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

Thank you for the excellent video, this is exactly the information I needed. Subscribed! 🌺

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 !!

I own the Purewell model with fluoride filters and the carbon. Total of (2) fluoride and (2) black carbon. Total of 8 stages. You can choose a chemical/mineral to focus on. Check your local water to see your chlorine or Fluoride level and choose accordingly 🤓

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

Thank you for this review. I’m looking at the alexapure.

Another good video, thank you very much.

Great video, I too was curious about how the Alexapure would stack up against the Berkey and the generic versions. I use a hard pump well at my cabin and currently have been using a Brita pitcher for drinking water, however the filters don’t last more than a month or so before they slow down to a crawl. Thanks for sharing your experience!

Vary informative nicely done 😊

Great review. Subscribed to your channel. Would love to see you do the AquaCera cerametix gf filter in one.

Kool Thanks for sharing!!

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.

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

I made another video to test these even further with some really interesting contaminants. When you’re done with this one, check it out! kzfaq.info/get/bejne/mbOWhLCB3biVnmQ.htmlsi=yJUmnnW15TjiQv2x

Love my purewell, could not afford the Berkey, the water is fantastic!

GREAT VIDEO!!! I just inherited a Berkey Light and find the peiming of the black filters a pain and expensive when purchasing the flouride/arsenic filter combo. Ive beenbteyingvto find outbif the 7" Sterasyl (ceramic) filter would be easier and reduce the need of buying the traditional combo. I would greatly appreciate your advice!

How does this compare to the water machine?

Wondering if anyone can answer this question for me. I have been using a Berkey filter system for several years and have been happy with it. I heard about the Zero water filter and thought I would try it. Since I can put it in my fridge. It came with a testing probe that measures dissolved solids in the water. I did a test on my tap water, Berkey water and the the Zero water. Tap water registered 149, Berkey 167 and Zero was actually zero. What is the Berkey adding into the water? Now I take the Berkey water and run it through the Zero filter pitcher. I have repeated the test on several occasions and comes out the same each time.

Can the contaminated water dripping down the outside get through the crack where they mate and contaminate the clean water underneath?

I watch your income school videos 😂

Wanting affordable water filtration system. Also want glysophates and other pesticides out of water. Not sure that after the first few hundred gallons if filters still filter out as well. Am still wanting other junk out of water too. Go get refills in gallon jugs. Tired of having to make trips and having lots of jugs sitting around. Thanks.

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.

I would like to have your reviews regarding the 4 Patriot water filter . I’m in the search for getting a water filter and would like to decide . Thank you !

Could you put in the more expensive filters in the cheapest one?

You said you decided on purchasing the Pure Well brand on the right. How did you get possession of the others for this video?

Does a Berkey filter or Alexapure pro filter fit in the Amazon Purewell housing?

Did you ever test the pro one?

Where did you purchase both the test kits from?

I live on rain water and use my pond during dry times... Berkey is the only filter I trust.. They are not the same, especially the Amazon specials.. Chinese knock offs can't filter what berkey does especially over time

Too bad you can't get the original Berkey water filters anymore. The new one is only for municipal tap water. I purchased 4 of them, so I am good for a while. I don't know if the other ones are able to kill viruses like the original Black Berkey filters.

Do you have an opinion as to what the best filters are

I wonder of you mixed up something like kool aid and ran it through them what would happen

None of then can take the salt taste out of my water (water softener salt) here in Florida:(

This filter can Remove fluoride from water

How about filter capacity on these?

ty for the time and efforts...but why would you ever add flouride?

Smaller Filter Pore Size - The filter pore size of Purewell gravity water filter is 0.01 microns so that it can filter out 99.99% tiny materials from the water while other brands' filter pore size is only 0.2 microns. The smaller filter pore size, the higher filtering accuracy. What's more, Purewell water filter system can maintain the optimal flow rate (4 gallon/hour) while the filter pore size is smaller.

Just an FYI, Berkey filters cannot be used with softened water. It damages the filters. Bummer!

If you can send it off to tap score it’s a much more intense testing

You NEED to pre filter the chunks and debri out as well as wiggles through at least a cheese cloth or cotton material to not clog your filters and to get maximum longevity out of you filters? I understand this is a youtube video but you should follow manufacturers recommended instructions to make it more accurate? Just a thought???

Alexapure only can do 200 gallons on a filter ? And berkey is 3000 gallons ??? Huge difference and for the price berkey filters are much better. If I am seeing the info right

Berkey most expensive because of the capacity of the black filters. Gal for gal its cheaper than the alexapure

Isn’t the most important thing to clean water the filter? If most of these filters are interchangeable why not get the most inexpensive stainless steel container you can find and put the best filter in it? Am I missing something

SO... where ware all the biologicals and contaminants going? Aren't they staying in the media, and growing, multiplying, clogging

This is all good, fine and dandy. We know they all work and they all work well. Look at the required municipal water test results that are available. Do you actually need a filter at all? Not saying yes, not saying no. What I want to know is what are municipal test results? Each person should do their own homework.

Drink them and do a video for us please😂

You keep saying bacteria. What about viruses??

Berkey is not even nfs rated. Wouldn't dare use it.

next time try to use actual lab results it will invoke a bit more confidence thanks

Thank you for putting to rest the whole more expensive is better idea. Berkey's are fine but their price point is ridiculous and nowhere do they demonstrate how their filters perform any better than their far less expensive competition. I don't care how many revisions they've made to their filter, how many were done strictly to lower manufacturing costs or supply chain realities? Proprietary means unique to them, not better performing It's a carbon filter utilizing pore size and ion exchange. The biggest actual difference is they cost about 80% more than a comparable competitor.

All the filters are interchangeable.

work on stop giggling and stop saying .... we..... its... I....
