Hello, I am creating a water filter using Moringa Olefiera. I need to test the effectiveness of it. I already have a TDS meter, but I can't afford a turbidity meter. What are some other ways I can test the efficiency of the filter? How can I test the effectiveness of a water filter on reducing turbidity?

There are also a number of resources on turbidity monitoring -- DIY and otherwise, here: https://publiclab.org/wiki/turbidity

Hi @gretchengehrke! Thanks for letting me know about this! I might actually be able to use it. However, one complication I have is the amount of liquid needed. I only have about 15 ml of liquid, so I don't know if the tube will work..

I wonder how they measured effectiveness of filtration!
