Better to just buy one system for whole house it’s cheaper per gallon treated.
You can’t get away from chemicals it’s in air food water and those you can not like without. Usda organic is a label but is pointless when you read and understand loopholes.
We just went through organic certification so I know what’s its about it is a basic fee for certification and don’t use these things in consentration over this and get caught. No gmo but if you get cross contamination that’s ok. Polluted ground water that’s ok. But no treated fence post unless already on land before certification I have never seen anything eat a fence post. They check for fuel spills but you can use certain things to clean that are downright toxic.
Yeah you can use antibiotics just have to wait the out of system date (anything that gets antibiotics here is breeding stock or sold into slaughterhouse system never into our food lines.)
Can use organic grain that used roundup to dry it as it does not count. Organic is a joke better know where your food comes from. Only difference is we now pay a fee so we can sell our meat for more and can relax our standards ro organic… Yeah right ……If I wont eat it i won’t sell it.
And for organic there has been huge scams on feed labeled organic just look it up like 35 percent or more of the feed labeled that is anything but. https://nypost.com/2019/08/21/farmer-kills-himself-to-avoid-prison-for-massive-organic-food-scam/
