What is the typical lifespan of a DuPure replacement filter?

While there is no reputable information discussing the typical lifespan of a DuPure replacement filter, reverse osmosis systems should have their filters replaced roughly once every six to nine months. Some other water filter membranes should be replaced roughly once every two to three years.

All DuPure filtration systems are designed to provide users with advantages such as improving the purity and clarity of the water, as well as its taste. Many of the filters are designed to fit underneath sinks to optimize counter space and eliminate the presence of chlorine. The systems also eliminate silt, bacteria, lead and other volatile organic particles in the water.
