“Filter as Black as Ink! When Was the Last Time You Replaced Yours?”
Peeking inside your water purifier to find a filter blackened like spilled ink is a stark reminder: maintenance can’t
be ignored. Over time, even in areas with “clean” tap water, filters accumulate a surprising amount of debris.

PP cotton pre-filters, designed to trap large particles, are the first line of defense. In just three months, they can transform
from white to dark gray, clogged with sediment, rust, and sand. Activated carbon filters, tasked with absorbing chlorine and
organic matter, develop a sticky, black residue as they adsorb toxins. Neglect these, and the result is reduced flow,
compromised purification, and even bacterial growth.

The danger lies in “filter blindness”—users grow accustomed to declining performance, unaware of the health risks. A clogged
carbon filter can become a breeding ground for bacteria, while an overworked RO membrane may start leaking contaminants

back into the water. In extreme cases, neglected filters have been found to harbor mold and even tiny organisms like diatoms.
So, how often should you replace filters?
- PP cotton: 3–6 months (depending on water clarity)
- Activated carbon: 6–12 months (sooner if water smells/tastes odd)
- RO membrane: 2–3 years (but flush monthly to extend life)
Signs it’s time to replace:
- Water flow is sluggish
- Tastes metallic or chlorinated
- The filter housing feels warm (a sign of bacterial activity)
Replacing filters is simpler than you think. Most systems use twist-and-lock or quick-change cartridges—no plumber needed.
Just remember to rinse new filters for 5 minutes to remove any manufacturing dust.

A blackened filter isn’t just an eyesore—it’s a ticking time bomb. Regular replacements ensure your purifier continues to deliver safe,
clean water, protecting your family from the hidden dangers of neglected maintenance.
