The frequency of changing a water filter will ultimately depend on a few elements. The type of filter will make a major difference as different types of filters have varying lifespans. Activated carbon filters, for example, typically last somewhere between 2 - 6 months while reverse osmosis membranes can last 1 - 2 years. It’s important to note that the more water you use, the faster the filter will become saturated and need replacement. Similarly, water quality can also contribute to the frequency of water filter replacement. If your water source is contaminated or has high levels of sediment, chemicals or other pollutants, you may need to change the filter more frequently.
As always, it’s recommended that you follow the guidelines provided by the manufacturer of your specific water filter system for optimal performance and replacement schedules. Regular maintenance helps to ensure that your water remains clean and safe to drink.
