Does this also remove chlorine and chloramines?

You need the Omnipure K2526-JJ for chloramine. The K2520-JJ does not filter chloramine. I’ve verified this with Omnipure.

Also is the plastic in the filters and tubes BPA free? And are we sure it doesn't leach at all?

All the components and filters that we used on this system is NSF certified which means that they won't leach anything back into the water. They are also BPA free.

Are all the materials sourced from the USA? Including the hardware, hoses, filter insides?

The majority of the components used on this system are made in USA or from US manufacturers. All 4 filters included in the system are made in USA.

I can't find the replacement RO membrane filter for this product. How much is the RO filter, and approxiately how many gallons is it good for? Thanks.

The filters will cost you $100-$200 per year depending how often you change them. FILTER-SET-CTOP pre-stage: $75 + FILTER-MAX-CTOP 4 stage: $150
