Under Sink Water Filter Cartridges

Undersink water filters are a critical component in every Australian kitchen. Thanks to our acid sulphate soils, bushfires and naturally occurring salinity, it’s important to ensure high-quality water while cooking and drinking from the tap.

That said, undersink water filters won’t stay in perfect condition forever. It’s critical to keep a close eye on your filter and replace any elements that lose their efficiency — especially the undersink cartridge itself.

At PSI Water Filters, we understand how much clean water matters to you and your loved ones. That’s why we specialise in high quality undersink water filters and their replacement cartridges, helping thousands of Australians keep their water supply in perfect condition.

Our replacement undersink cartridges

PSI Water Filters offers undersink water filter replacement cartridges for every model. You’re welcome to select an option that best works for you and the quality of your water supply.

Our most popular replacement cartridges include:

  • Omnipure OMB934-1mpb
  • Matrikx PB1
  • Aragon

You can browse our full collection of undersink cartridges at any time.

FAQs

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

Undersink water filter replacement cartridges typically last 6 to 12 months. Larger families may need to replace their filters more frequently, especially if their system receives heavy use. Couples or single persons, however, may only need to replace their filters once per year.

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

The signs of a failing undersink water filter are quite obvious:

  • Changes in colour
  • Poor flavour or taste profiles
  • Strong or foul odours

Contact PSI Water Filters for more information if you aren’t sure about your undersink water filter.

How do I choose the right replacement cartridge for my undersink water filter?

Your current undersink water filter may have instructional guidelines explaining the types of replacement cartridges available for purchase. But if that’s not the case, PSI Water Filters would be happy to help. Reach out to us via phone, email or contact form to chat about your needs.
