Whole house water filtration system to prevent MAC & NTM

I have heard from several sources that reverse osmosis, like granulated carbon filters harbor NTM. Here’s an article from the EPA.

I heard that too, but also heard that if the reverse osmosis system has UV filtering after the carbon layer, it should take care of NTM and other bacteria. Without being able to test it oneself, its really hard to know. I wish they sold personal NTM testers 🙂

You are correct! I think with the reverse osmosis the first filter is GAC the other 2 are different. However a posted read in here from Dr Falkingham who I suppose is highly regarded in USA and states that 0.2 will filter NTM out but also states that GAC filters should be changed every 2 weeks for that very reason. That would be an expensive outcome with any water filtration system. Filtration companies say filters last 6 to 12 months. Yes I agree they do breed and promote NTM.
I won’t be investing in filtering water for these reasons.
