Signs It's Time to Replace Your Water Filter
Instead of relying solely on manufacturer guidelines, it's best practise to watch for signs that your water filter might need replacing. Filters can become less effective over time, and recognising these signs early can help maintain the quality of your water.
Here are some common indicators that it's time for a new filter cartridge:
Reduced Water Flow: If you're noticing slower water pressure or a drop in flow from your tap or dispenser, your filter could be clogged. As filters trap sediment and impurities, they can gradually become blocked, which restricts water flow and reduces efficiency.
Changes in Taste, Smell, or Appearance: Water that suddenly tastes or smells different-or looks cloudy-may be a sign that your filter is no longer working as it should. When a filter reaches its capacity, it stops effectively reducing unwanted elements, leaving your water less clean and fresh.
Filter Lifespan Reached: Each filter has a recommended replacement interval set by the manufacturer. While actual usage can vary depending on water quality and volume, it's important to stay close to those timelines. Filters are built to handle a specific amount of water, and once that limit is reached, their performance declines.
Indicator Light or Display Alert: Some filtration systems come with built-in indicators that let you know when it's time to change the filter. These alerts-usually a flashing light or display message-are especially common in fridge or under-bench units and act as helpful reminders to replace the cartridge.
Scheduled Maintenance Reminder: If you're following a maintenance schedule and the time has come for a filter change, it's best not to delay. Regular replacement ensures your system continues to provide reliable, great-tasting water.

Filtration Canterbury has been an absolute pleasure to work with. I feel like they truly go above and beyond to make sure I'm taken care of and get the right system for our busines and home. Highly recommend!
I live in an area with Nitrate levels much higher than the NZ standard. It was very easy to install, highly efficient at removing Nitrates from the water, and surprisingly affordable!
