Amway introduced their first water treatment system back in 1984. In just about 20 years, the initial Amway water filter evolved into one of the most complete water filters on the market. We offer filters for Amway filtration systems, also known as Amway Quixtar water filter systems. These water filter replacements are compatible with the Amway e85 water filter, and Amway e84 water filter. These water filters fit in all Amway full-size filter housings, as they are designed with the same threaded connection as the original Amway water filter.
