Your Filter Looks Like a Polluted Swamp? Here’s Why You Need Urgent Replacement
A neglected water purifier filter is a ticking time bomb. After months of use, filters become saturated with
sediment, rust, bacteria, and even mold. If your filter appears black, slimy, or emits a foul odor, it’s long
past its prime—and continuing to use it is essentially drinking contaminated water.

Each filter type has a specific lifespan. Pre-filters (PP cotton), designed to trap large particles, typically
last 3–6 months. Activated carbon filters, crucial for removing chlorine and chemicals, should be replaced
every 6–12 months. Reverse osmosis (RO) membranes, the heart of many purifiers, can last 2–3 years
but require regular monitoring.

To avoid health risks, establish a maintenance routine. Use purifiers with built-in filter indicators or set
calendar reminders. Some models even offer subscription services for hassle-free replacements.
