💧 1. Change in Taste or Odor
If your water suddenly tastes metallic, salty, or smells strange (like chlorine or mold), it's a clear sign your filter is no longer effective.
💧 2. Decrease in Water Flow
A clogged filter can block water flow. If water pressure from your faucet or purifier drops significantly, the filter is likely full of sediment.
💧 3. Visible Dirt or Discoloration
Some filters (especially in transparent housings) may show brown or dark deposits. This is a sign the filter is saturated and no longer filtering effectively.
💧 4. Filter Lifespan Has Passed
Most filters have a recommended lifespan (e.g. 3 or 6 months). If you’ve passed that timeframe, replace it—even if the water looks clean.
💧 5. You or Your Family Feel Unwell
Dirty filters may let bacteria or heavy metals through. If family members experience stomach discomfort, dry skin, or hair issues, check your filter.
✅ Final Tip:
Don’t wait until the water “looks” dirty. Replace filters regularly as part of your home maintenance.
