Hi Ian

I have written about DIY filter methods and came to the conclusion that people should not really do this unless they are in an emergency situation.

The question you asked is my very reason for being weary about this method of filtration: how do you know when it has stopped working?

Regular filters will come with an indicator to tell you when the filter needs to be changed.

My recommendation is that you use a water test kit to regularly test the water and keep a record somewhere. Once you have done this over a long period of time you may be able to roughly work out the right amount of time for future filter changes.

Hey Luke!

Thanks for the quick response, I totally missed that you had responded!
I am, as much work as it will be, determined to figure out this DIY filtration system. I will be sourcing water from tap, so I am mostly just concerned with filtering out harsh metals that tap water has in it.
I have done more research and found a seller for granular activated charcoal and am happy with it. The main question I can’t seem to find anywhere is how to determine how often I need to change my charcoal out. Could you point me in the direction of any sources?

Hi Ian

I usually advise against DIY filters because it’s not an exact science.

You will need to know what your water is contaminated with, know which materials will effectively treat it and how much is needed.

If you’re determined to do it this way you will need to go through a lot of trial and error.

However, the best way to check if your DIY filter is effective is to get a water filter test kit to check the results.

Stay hydrated,
Luke
