When do you know to change your filters.
Dirty Filters
You usually know it’s time to change your water filters when you notice one or more of these signs:
Bad taste or smell in the water.
Reduced water pressure or slow flow.
Cloudy or dirty-looking water.
Filters changing color or looking heavily stained.
Increased scale build-up on kettles, taps, or appliances.
Unusual noises from the purification system.
The system’s service indicator light or alarm turns on.
It has reached the recommended replacement period.
Filter Type
Recommended Change
Sediment Filter – Every 3–6 months
GAC Carbon Filter – Every 6–12 months
CTO Carbon Filter – Every 6–12 months
Reverse Osmosis Membrane – Every 2–3 years
UV Lamp – Every 12 months
Several factors can shorten filter life:
Poor municipal or borehole water quality.
High sediment levels.
Heavy daily water usage.
Rust, chlorine, or bacteria in the water.
Regular filter changes help protect your health, improve water taste, and keep your purification system working efficiently.
