FAQs

How often do standard water filter replacement cartridges need to be replaced?

Standard water filter replacement cartridges should take place every six to twelve months. However, depending on your water quality or frequency of use, you may want to adjust that timeline.

Replacement frequency also depends on the filter type. For example:

  • Sentiment filters should be replaced every six to twelve months
  • Post-filters should be replaced every six to 12 months
  • UV filters should be replaced every 12 months

Contact PSI Water Filters for more information.


What are the signs that my water filter replacement cartridge needs to be replaced?

You may need to replace certain water filters if they display a significant loss in quality. Keep an eye out for:

  • Low pressure
  • Shifting ‘flavours’
  • Changing colours
