Water filters work hard to remove contaminants and deliver fresh, clean water, but they don’t last forever. Regularly replacing your water filter is key to maintaining water quality and system efficiency. From knowing how often to change your filter to recognising the signs of wear, understanding proper maintenance will help you get the most out of your water filtration system.
How Often Should You Change Your Water Filter?
The frequency of filter replacement depends on the type of water filtration system you have and your water usage. Here are some general guidelines:
- Household filters (e.g. under-sink, benchtop filters): Replace every 3-6 months, depending on water quality and usage.
- Reverse osmosis systems: Replace pre-filters every 6-12 months and the RO membrane every 2-3 years.
- Whole house filters: Replace every 6-12 months, though high-demand systems may need more frequent changes.
- Fridge water filters: Replace every 6 months or as recommended by the manufacturer.
- UV filters: UV lamps need replacement annually.
Always consult the manufacturer’s guidelines for timeframes and how to change your water filter, as the specifics may vary.
Signs That It’s Time to Change Your Water Filter
Even if you’re following the recommended schedule, some signs may indicate it’s time to replace your filter sooner:
Reduced water pressure: A clogged filter restricts water flow, causing noticeable drops in pressure.
Unpleasant taste or odour: If your water tastes metallic, sour, or smells strange, the filter may no longer be removing impurities effectively.
Visible sediment or discolouration: If you notice particles in your water or discolouration, the filter could be saturated.
Unusual noises from the system: Strange gurgling sounds may indicate the filter is struggling to function properly.
