Water Filter Cartridge Change: How Often Should You Do It?
Introduction
Have you ever tasted something and said “this is not how water is supposed to taste”? If so, you’re probably due for a new water filter.
A solid water filtration system is a necessity for many Australian households. It helps maintain the cleanliness and safety of drinking water.
But here’s the thing — no filter lasts forever. If you don’t swap them out in time, they don’t do their job well, and that means your water may not be as fresh or safe as you believed.
Don't ignore the warning signs of an old filter
So, how often should you change the water filter cartridge? Let us take it one step at a time.
Why You Need to Change Your Water Filter Cartridge
A water filter operates by catching impurities, but over time, those contaminants accumulate. Here’s what happens when you leave a filter too long:
- ✅ Water Quality Drops – Your filter stops catching unwanted particles, letting chlorine and other chemicals pass through.
- ✅ Bacteria Can Grow – Old, overused filters can become a breeding ground for bacteria.
- ✅ Slower Water Flow – If water takes forever to pour, your filter is likely clogged.
- ✅ Bad Taste or Smell – When your water tastes strange or smells weird, you need to get new.
When Do You Replace Your Water Filter Cartridge?
The timing will all depend on your type of filter, how much water your household uses and your local water quality.
| Filter Type | Replacement Time | Care Tips |
|---|---|---|
| 7 & 8 Stage Filters | Every 6 months | Rinse under running water before installation. |
| Magnesium Prill Beads | No replacement needed | Wash occasionally; boil in water for 5-10 mins. |
| Maifan Stone | Every 12 months | Boil with salt water every 3 months. |
| Fluoride Reduction Dome | Every 6-12 months | Gently scrub under cold water. |
| Sediment Dome Filter | Every 6-12 months | Clean and wipe; replace felt pads at the same time. |
| Ceramic Dome Filter | Every 6-12 months | Use a soft sponge to clean, no soap. |

Signs It’s Time for a New Water Filter
Not sure if your filter needs replacing? Watch for these clues:
- 🚰 Funny Taste or Smell – If your water tastes like chlorine or metal, your filter isn’t working.
- 💧 Slow Water Flow – If your filter takes more time than usual to fill a glass of water, then it is dirty and clogged.
- 🦠 Visible Particles in Water – If you notice bits in your water, that’s time for a change.
- 🛑 Strong Chlorine Odor – A heavy chlorine smell means your filter isn’t removing chemicals effectively.
A Customer’s Story: The Forgotten Filter Swap
Sarah from Brisbane didn’t think much about her water filter—until her morning coffee started tasting odd. “I thought maybe my coffee beans had gone bad,” she recalls. But when her kids also complained about the water, she checked her filter. Turns out, she had gone three months past the recommended change date! After replacing it with a ceramic dome filter, the water was instantly better. “I won’t make that mistake again!” she says.

How to Pick the Right Replacement Filter
Choosing the right filter matters. Here’s what to consider:
- Make Sure It Fits – Always check compatibility with your existing filtration system.
- Know Your Needs – For example, if you need to remove fluoride, choose a fluoride reduction dome.
- Think About Water Usage – If your family goes through a lot of water, you may have to change out filters more frequently (usually we recommend every 6 months to maintain maximum efficacy).
- Check Local Water Quality – If you’re in a high-sediment area, consider a sediment dome filter.
