The frequency at which you should change your water filter depends on the type of filter and your usage level. Most manufacturers recommend changing pitcher and faucet-mounted filters every 2 to 3 months. Under-sink and whole-house filters often have a longer lifespan, typically needing replacement every 6 to 12 months. However, if you notice a decrease in water quality or flow rate, it might be time to change the filter sooner.
