How Often Should I Change The Filters Inside of My Reverse Osmosis System?

🚰 Your Reverse Osmosis System Is Quietly Keeping a Secret…

It sits silently beneath your sink.
Day after day. Glass after glass.
Delivering clean, crisp drinking water you trust.

But here’s the truth most homeowners don’t realize:

👉 Your reverse osmosis system is only as good as its filters.
And when they’re overdue… the water you think is pure may not be.

At Water Fixers Plumbing & Filtration, serving the Central Coast for 38 years, we see it all the time—systems struggling quietly until one day they fail, leak, or stop protecting your water altogether.

Let’s break it down before that happens to you.

⏰ The Real RO Filter Change Timeline (No Guesswork)

🔹 Pre-Filters (Sediment & Carbon)

Every 6–12 months

These are your system’s first line of defense—trapping dirt, sand, rust, chlorine, and chemicals before they reach the RO membrane.

💥 When overdue:

• Pressure drops
• Taste and odor issues creep back
• The System can stop making water
• Your membrane wears out faster (and that gets expensive)

---

🔹 RO Membrane (The Heart of the System)

Every 2–3 years

This is the powerhouse—removing dissolved solids, salts, hardness, heavy metals, bacteria, inorganic and organic contaminants you never want in your drinking water.

⚠️ When it’s neglected:

• TDS levels climb
• Water tastes “off”
• You’re no longer getting true RO-quality water

---

🔹 Post-Carbon / Polishing Filter

Every 6-12 months

This is the final touch—making your water taste clean, fresh, and crisp.

😬 When overdue:

• Flat or stale-tasting water
• Volatile Organic Chemical and Hydro-carbon Gas bleed thru
• Water-borne Bacteria and Cyst contamination
• Odors returning
• “Why doesn’t my water taste like it used to?”

🚨 Signs Your RO System Is Crying for Help

If any of these sound familiar, your filters are overdue:

• Slower water flow
• Cloudy or odd-tasting water
• Gurgling noises
• Leaks under the sink
• “It’s been years… I think?”

(You’re not alone. We hear that last one daily.)
