Water Purification Filter Replacement and Maintenance
" Filter Replacement and Maintenance Guide for Water Purification Devices
”
Why Regular Maintenance?
Regular maintenance directly affects water taste, hygiene, and device life. Delayed changes can lead to bacterial growth, taste/odor issues, and membrane damage.
General Change Intervals (Depending on Usage and Water Quality)
Sediment Filter: 3–6 months
Pre-Carbon (GAC/Block): 6–12 months
RO Membrane: 18–36 months
Post-Carbon (Sweetener): 6–12 months
Mineral/Alkaline Filter: 6–12 months
Tip: Frequent tea/coffee consumption and high TDS may require more frequent changes.
Signs It's Time for a Replacement
Taste and odor change
Decrease in flow rate
Increase in TDS value
Cloudiness or sediment in faucet
Simple Maintenance Checklist
Monthly: Visual inspection (leaks, cracks, corrosion)
Every 3 Months: TDS measurement and flow rate observation
Every 6 Months: Sediment + Carbon replacement (depending on conditions)
Yearly: Hose, connection, and faucet seal inspection
Months 18–36: RO membrane test/replacement
Estimated Annual Cost (Example)
Sediment + Pre-Carbon + Post-Carbon: ₺1–₺2
Mineral/Alkaline (optional): ₺1–₺2
RO Membrane (every 2 years): Depreciation based on ₺1–₺2/year
Note: Varies by brand and model; check local pricing.
Professional Service or DIY?
DIY: This can be practical in filter cassette systems.
Service: Recommended for initial installation, leakage, and pressure testing. This protects the warranty.
FAQ
What happens if I change the filter too late?
Taste/odor will be impaired, the risk of bacteria increases, and the membrane may be damaged.
How do I use a TDS meter?
Draw water from the device tap, immerse the meter, and note the readings periodically.
What should I do if I'm on a long vacation?
Upon return, drain some water from the system; replace the carbon filter if necessary.
