Custom DIY 3-Stage Water Filtration System

I built a custom Doulton 3-stage water filtration system to suit my own drinking water needs. You can buy the same system directly from Doulton for 9 (IP300UC+).

Here is a Doulton candle specification chart to help select the best filter for the job:

As described in the video here are the parts used…

1) Sediment/Heavy metal:

TDS meter:

Disclaimer: I have no affiliation with Doulton or Fresh Water Systems. They both happened to be the best I could find for my budget and individual needs. Both offer great customer service in my experience. I’m only linking to their sites so that someone interested in building their own system can do so without spending all the time I spent hunting the individual components down.
