435 R.O. Pre & Post Filters with Membrane Set for TFC-25D , TFC-4, TFC-435

On my ro, i have a label for "prefilter" and "precarbon." does the white sediment filter go in "prefilter" and the blue gac go into "precarbon?"

Are each of these filters individually wrapped?

I have a rayne pure plus model with all four filter numbers the same , will they work in my RO system?

Does this kit come with K2333-kk filter?
