How often should I change the filter?
How often should I change the filter?
For the best filtration performance, we recommend replacing the filter every 30–45 days, depending on your water quality and household usage. In lighter-use households, a filter may last up to 60–90 days, but it should be replaced sooner if you notice reduced pressure, discoloration, odor, or buildup.
