How often do I have to change the filters and media?

The NanoPURE™ system has two pre-filters and the NanoPURE™ media filter. The first pre-filter is a 5 micron sediment filter that needs to be replaced every 3-6 months (depending on water contamination). The second pre-filter is the KDF85 carbon filter and it needs to be replaced once a year. The final NanoPURE™ media filter will last a minimum of 2-3 years and depending on the amount of water usage could last even longer. Retrofit filters will only last 2 years. Whole office systems will last 3 years or longer.
