AquaTru vs Clearly Filtered: RO vs Advanced Pitcher Filter
Clearly Filtered makes one of the best pitcher filters on the market. AquaTru is one of the best countertop RO systems. They're solving overlapping but different problems — and which one is right for you depends on what's actually in your water.
The key differenceClearly Filtered cannot remove fluoride or nitrates. AquaTru can.
Clearly Filtered's Affinity Filtration technology is exceptional for a pitcher — it removes lead, PFAS, chlorine, and hundreds of contaminants. But pitcher filters physically cannot remove dissolved ionic compounds like fluoride, nitrates, and arsenic. Reverse osmosis can. If those are your concerns, you need RO.
| Feature | AquaTru | Clearly Filtered |
|---|
| Filtration technology | Reverse osmosis (4 stage) | Affinity Filtration (pitcher) |
| Removes fluoride | Yes — 93%+ reduction | No — fluoride passes through |
| Removes nitrates | Yes | No |
| Removes arsenic | Yes — 97%+ | Partially |
| Removes PFAS | Yes — NSF P473 certified | Yes — claims 99.9%+ (certified) |
| Removes lead | Yes — 97%+ | Yes — certified |
| Removes bacteria | Yes | No |
| Requires electricity | Yes | No |
| Water waste | ~0.6:1 | None |
| Speed | Fast (electric pump) | Slow (gravity-fed) |
| Price | $350–$449 | $90–$120 |
| Annual filter cost | $100–$120 | $60–$80 |
When AquaTru is the right call
- Your water has elevated fluoride, nitrates, or arsenic
- You live in an area with known PFAS contamination
- You want to remove the broadest possible range of dissolved contaminants
- You want on-demand fast dispensing rather than waiting for gravity filtration
When Clearly Filtered is good enough
- Your water quality concerns are primarily lead, PFAS, and chlorine — not fluoride or nitrates
- Budget is a significant factor — $90 vs $449 is a real difference
- You don't want to use electricity or deal with water waste
- You want the convenience of a pitcher you can grab from the fridge
Check your local water report first
Before spending $449, run your zip code through the EWG Tap Water Database (ewg.org/tapwater). If fluoride or nitrates are flagged as contaminants of concern in your area, you need RO. If the primary issues are lead and chlorine, Clearly Filtered handles those well at a fraction of the cost.
