🧠 Why Filter Changes Are Crucial in RO Purifiers

Each filter in your RO purifier plays a unique role:

Pre-filters remove sediment and dirt
Carbon filters remove chlorine and odors
RO membrane removes dissolved salts and heavy metals
Post-carbon filters polish the taste

With time, these filters become clogged or ineffective. Delaying replacements can:

Compromise water quality
Increase health risks
Damage other components
Reduce purification speed

📅 When to Change RO Filters

Here’s a general timeline for each filter:

Filter Type	Replacement Frequency	Function
Pre-Filter	Every 3–6 months	Removes large particles and dirt
Carbon Filter	Every 6–12 months	Removes chlorine, odor, organic chemicals
RO Membrane	Every 12–18 months	Filters dissolved solids, heavy metals, bacteria
Post-Carbon Filter	Every 12 months	Enhances taste and smell
UV Lamp (if present)	Every 12 months	Kills microbes using UV light

📌 Note: These timelines may vary based on water quality and usage.

🚩 Signs Your RO Filters Need Replacement

Watch for these signs indicating it’s time to replace filters:

🛑 Bad taste or odor in water
⏳ Slow water flow
