Review on Enhance Your Water Quality 💧 with iSpring ACL1 Add Filter White by Michelle Ramanath

I used this to add an extra 6th stage which I later wanted to install on my Ispring RCC7 which was an alkaline/mineral filter. Went like clockwork! The larger part connects to the body of the reverse osmosis membrane and the smaller part connects to the alkaline filter, so you have a V shape on top of the reverse osmosis membrane, which consists of a 5th stage carbon filter on a "V" side consists. and closer to the inside of the case is another V-shaped top, which is an alkaline filter.
