(Eco ) Rainwater filter

Hello is there a" air quotes "(eco) water filter that could be used for filtering rainwater? I plan on using a first flush system and leaf mesh on the gutter. This is for a potable system

Something missing?

Depends how you define "eco" and how much filtering the water needs. In a well-designed rainwater system, the water should stay clean.

If filtering is needed, slow sand filters are most eco of all, there's at least one person here using that system. In commercial systems, Berkey water filters aren't 100% environmentally friendly as the ceramic filters need replacing periodically, but they're far better than plastic water filters.

So pretty much if i could get clean water into the tanks also keep bugs and sun out. There isnt much need for a filter? We do run a Berkey for are drinking water now just wanted to not have to rely on it. ill check out the slow sand filter. Thank you for your time and reply

I seen your other post thank you

I think the filtering needed depends on how clean the gathering surface is. Some surfaces leach into the water, and then there's bird poop, tree litter that can break down, dirt/dust, possibly car emissions that settle on the surface over time and is washed off with the rain. A first flush can handle a lot of that, but I would still test the water regularly or include a ceramic filter or two for anything you'd drink or cook with.

We usually have a filter barrel between our roof and cistern,  but it's temporarily off (read: I need to fix it) but I was wondering if anyone has ever used clay flower pot pans as a rough filter for non potable water cleaning. Same premise as a berkey,  but with a bisque fired clay pan as the separator between the raw cistern water and the reservoir of cleaner water?

The first flush usually has small and soluble detritus, so volume is important or as some first flush unit have a drain to allow slow discahrge.
