Trolley diy wfp

[Deleted member 2617]

hey guys just want to ask a silly question

I've seen diy wfp systems and they don't use resin how does it purify the water without the resin ??

The water is purified before going into the system, you could incorporate this into the system if you wanted?

Most use RO and not just resin.
