Replacement Filter Kit Compatible with Topway Global (TGI) TGI-525 RO System - Includes Carbon Block Filter, PP Sediment Filter, GAC Filter & Inline Filter Cartridge

Filters fit my TGI System. Except for the fact that the carbon filter in place after the membrane came without the collar connections to stick the plastic water lines into! I removed the o-rings and collars from my old filter and they did not work. I have written the seller. I guess I'll find out if I'm wrong for not expecting to take this thing to the store to get the right connectors for it, or if they are wrong for not including them.Update / Seller offered to send connections for my system. I told them, I would need the whole filter because I screwed it up trying to make it work. I don't know if they will send it or not, but a five star will come if they do. After all my TGI system is only 3 years old and the information for this product specifies my brand system! Apparently some of the systems have screw in attachments for the post carbon filter. But my newer TGI system they say this replacement system of filters fit....DOES NOT. So if you have screw in attachments for the post carbon filter, it WILL work for you. I have quick connect collars for mine, just like the rest of the system.
