Your water might look clean. It might even taste okay.
But if you haven’t changed your filters in a while, your well water system could be working overtime—and not doing its job the way it should.
Replacing filters is one of the most important (and easiest) parts of water treatment system maintenance. And yet, many homeowners forget about it… until something smells, tastes, or feels wrong.
In this article, we’ll show you how to tell when your filters need changing, why it matters, and how often to do it—especially here in Southwest Florida, where water conditions can be extra harsh.
Why Filters Matter in the First Place
Water filters are like the unsung heroes of your system.
They trap dirt, iron, chlorine, sulfur smells, bacteria, and even bad tastes before that water gets to your faucet.
If your filters are clogged or worn out, you’re basically drinking, cooking, and showering with untreated water.
Signs Your Filters Are Ready to Be Replaced
You don’t have to be a water expert to spot a tired filter. Here’s what to watch for:
1️⃣ Bad Smells or Tastes
If your water starts smelling like rotten eggs or tasting metallic, it could mean your carbon or sulfur filter is used up.
2️⃣ Rust or Stains in the Bathroom
Orange or black stains in sinks, toilets, or showers? That’s usually iron or manganese getting past an iron filter that needs changing.
3️⃣ Cloudy Water or Particles
Sediment filters trap sand, grit, and debris. When they’re full, it all slips right through—and into your glass.
4️⃣ Low Water Pressure
Clogged filters restrict flow, which can make your showers weak and your faucet pressure drop.
5️⃣ It’s Been Over 6 Months (Or You Can’t Remember)
If you’re scratching your head trying to remember the last time you changed your filters… it’s time.
Which Filters Are We Talking About?
Here’s a quick guide to common filter types and what they do:
| Filter Type | What It Does | When to Replace |
|---|---|---|
| Sediment Filter | Removes sand, dirt, and debris | Every 6–12 months |
| Carbon Filter | Removes chlorine, smells, and taste | Every 6–9 months |
| Iron Filter Media | Removes iron and sulfur | Clean annually, replace every 3–5 years |
| RO Membrane | Filters out contaminants like lead, fluoride, and bacteria | Every 2–3 years |
| Pre/Post RO Filters | Protect and polish water in RO systems | Every 6–12 months |
Note: Water in Fort Myers and Lehigh Acres can wear out filters faster due to higher levels of iron, hardness, and sulfur. So when in doubt, replace sooner than later.
