Review on Enhance Your Water Quality 💧 with iSpring ACL1 Add Filter White by Brooke Rogers

This optional filter comes in handy when you are looking to upgrade from a 5 stage to a 6 stage reverse osmosis system but the drawings and actual kit don't match and is still working. Just note that you need to make sure the fittings are suitable for your system. This kit will not work for all reverse osmosis systems. However, a few brackets, hoses and unusable fittings don't justify the price.
