Do you have lab reports showing the water specs before and after filtration?

I’d like to see the specs too compared to the more expensive ones. I bought these and I can tell you the flow is a lot faster than the other ones which is concerning

Does anyone know if this also removes pesticides like the berkey? There is no detailed description on what it removes. Thanks for the help!

I sent mine back after reading to only filter treated water. Whereas the Berkey’s can filter pond water if needed. It’s not an apples to apples comparison The Berkey’s are patented multi-media filters designed to filter contaminated water. Wheras these filters are coconut charcoal designed to filter tapwater.

Why are the TDS much higher than tap water after filtering the water

No idea, but stick with the Berkeley filters. These knock-offs suck. They do not filter as well, and the documents sent with the filters tells you they are not to be used outside of a domestic water system. May as well buy a brita filter instead of these. I made the mistake of getting them and noticed right away how bad they are.

How do I perform the red dye test and where do I get it?

It is not something you get. Once you have your filters installed fill your system with water. Then add a few drops of red food coloring. If your filters are working right the water once it has run through the filters should come out clear. Hope that helps.
