A pitcher that does something almost no other does: reduce bacteria, viruses, and cysts, alongside lead and PFAS, using a nanofiber filter. That makes it a real option for well or untreated water, if you accept a slow pour, short filter life, and lab-tested rather than NSF-certified results.

The rare pitcher that filters microbes, for the water that needs it
Almost every filter pitcher is built for treated city water, where the utility has already killed the germs and your job is taste and chemicals. The Epic Nano is built for the water that has not been through that: its nanofiber filter has pores small enough to physically strain out bacteria, viruses, and protozoan cysts, Giardia, Cryptosporidium, E. coli, and MS2 virus among them, which the vast majority of pitchers cannot touch. It does this alongside reducing lead, chromium-6, PFOA and PFOS, heavy metals, and pesticides, so on paper it removes a very wide range. For a well, a cabin, an RV, travel, or an emergency kit, a pitcher that handles microbiology is genuinely useful.
Two honest caveats keep it out of the top tier. First, certification: Epic has its filters independently tested by EPA-accredited laboratories to NSF/ANSI methods, including microbiological protocols, but the Nano is not itself NSF-certified as a system. That is credible third-party data, better than marketing-only claims, but not the same as a certification. Second, the trade-offs of squeezing water through such a fine membrane: it pours slowly, and the filter clogs faster than a carbon cartridge, needing replacement every two to five months at around $50 a time, so running cost is high. It also does not remove fluoride. For everyday municipal water, that combination makes it more filter, and more hassle, than most people need.
Best for: well water, untreated or questionable supplies, cabins, RVs, travel, and emergency kits, where reducing bacteria and viruses matters and a slow pour is acceptable. On treated city water, a certified filter does the job you actually need for less money.
How it scored, category by category
Each category is weighted into the overall score. The Nano’s broad, microbe-reducing filtration scores well, but its slow flow, short filter life, and lab-tested rather than certified status pull the total down.
What it removes
The figures below come from Epic’s independent EPA-accredited lab testing. They are credible third-party data, but the Nano is not NSF-certified as a system, so we report them without crediting them as certifications.
| Contaminant | Reduction (lab) | Certified? |
|---|---|---|
| Bacteria, viruses, cysts | 99.999% | Lab-tested |
| Lead | Reduced | Lab-tested |
| PFAS (PFOA / PFOS) | Reduced | Lab-tested |
| Chromium-6, heavy metals | Reduced | Lab-tested |
| Pesticides, industrial chemicals | Reduced | Lab-tested |
| Fluoride | Not removed | Keeps minerals |
Epic has the Nano independently tested by EPA-accredited labs to NSF/ANSI methods, including microbiological reduction, but it is not NSF-certified as a system. Its microbe reduction is the real differentiator, most pitchers do not attempt it. It does not remove fluoride. If you want a certified pitcher, or fluoride removal, see our Clearly Filtered pitcher review and fluoride guide; for certified lead and PFAS, our lead guide.
Pros and cons
What we liked
- Reduces bacteria, viruses, and cysts, rare in a pitcher
- Also cuts lead, PFAS, chromium-6, and pesticides
- A real option for well, untreated, and travel water
- No install, keeps beneficial minerals, US-made
Worth considering
- Lab-tested to NSF methods, but not NSF certified as a system
- Slow pour; the fine nanofiber membrane takes its time
- Short filter life (2 to 5 months) and high running cost
- Does not remove fluoride; overkill for treated city water
What actual owners report
Our score reflects tested performance. Owner sentiment, summarized from verified buyer and independent long-term reviews, is enthusiastic among its target users, with speed and filter cost the recurring gripes.
Owners on wells or unsure supplies value the peace of mind of a pitcher that tackles microbes, and most like the clean taste. The consistent frustrations are how slowly it pours and how often the filter needs changing.
Owners consistently praise
- Confidence filtering well, cabin, or travel water
- Broad removal and clean, still-mineral taste
- Simple, no-install pitcher that goes anywhere
Common complaints
- Slow to filter a full pitcher
- Filters clog and need replacing every few months
- Higher running cost than a standard carbon pitcher

The details
Common questions
What makes the Epic Nano different from other pitchers?
Its nanofiber filter has pores fine enough to physically strain out bacteria, viruses, and cysts, which almost no other pitcher attempts. That, plus reduction of lead, PFAS, chromium-6, and pesticides, makes it suited to well water, untreated supplies, travel, and emergencies rather than everyday city water that is already disinfected.
Is the Epic Nano NSF certified?
Not as a system. Epic has the Nano independently tested by EPA-accredited laboratories to NSF/ANSI methods, including microbiological protocols, which is credible third-party data. But it does not hold a formal NSF certification the way Epic’s own Smart Shield under-sink filter does. If certification matters to you, that is worth weighing.
Does it remove fluoride?
No. The nanofiber filter targets microbes, metals, and organic chemicals, not fluoride. If fluoride is your concern, you want a fluoride-specific pitcher like the Clearly Filtered, or reverse osmosis such as the AquaTru Carafe. See our fluoride guide.
Epic Nano or Epic Smart Shield?
Different jobs. The Nano is a pitcher for untreated or well water, where microbe reduction matters, and for travel. The Smart Shield is a certified under-sink filter for everyday city water, cheaper to run and NSF-certified. On municipal water, the Smart Shield is the better, better-value pick; choose the Nano when your water is not reliably treated.
Should you buy it?
Buy the Epic Nano if your water is not reliably treated, a private well, a cabin, an RV, travel, or an emergency stash, where a pitcher that reduces bacteria, viruses, and cysts is genuinely valuable. Few pitchers can do that, and the Nano does it while also cutting lead and PFAS. For everyday municipal water, though, its microbiological edge is protection you probably do not need, and you pay for it with a slow pour, a filter that clogs every few months, and lab-tested rather than NSF-certified results. On city water, we would point you to Epic’s own certified Smart Shield under-sink filter, a certified pitcher like the Clearly Filtered, or reverse osmosis. Match the tool to the water: the Nano earns its place when the water is questionable.
