To remove microplastics from water, you need a method that physically strains out particles down to the sub-micron range — not a taste-and-odor carbon pitcher. Reverse osmosis removes the most: its membrane pores are about 0.0001 microns, far smaller than the smallest microplastics and most nanoplastics, so it strips out well over 99% of plastic particles plus PFAS, lead and more. Distillation is comparable — it boils water to steam and leaves the plastic behind. Below those, a 0.01-micron ultrafiltration under-sink unit, a hollow-fiber pitcher (like the Epic Pure, tested to 99.9%), a faucet filter and a filtered bottle each remove microplastics at different budgets and levels of effort. One thing that doesn’t filter them out on its own is boiling — though in hard water it can trap some particles in the scale. And skip bottled water: a 2024 study found roughly 240,000 plastic particles per liter in it, mostly from the bottle itself. Filter your own tap water and store it in glass or steel.
Microplastics — plastic fragments smaller than 5 millimeters, down to nanoplastics you can’t see — have been measured in tap water, bottled water and treated municipal supplies around the world. They enter water from degrading plastic waste, from the plastic pipes and bottles the water moves through, and from the treatment process itself. The World Health Organization’s 2019 review concluded the health risks aren’t yet fully understood, but it also flagged how little we know about the smallest particles — exactly the ones most able to cross into tissue. Until the science settles, the sensible move is the same one you’d make with any uncertain exposure you can cheaply cut: reduce it.
Here’s the part most “microplastic filter” marketing skips: removing a plastic particle is a matter of pore size, not branding. A pitcher that filters by activated carbon alone is built to improve taste and strip chlorine — it doesn’t reliably strain out particles. To actually remove microplastics you need a physical barrier fine enough to catch them (reverse osmosis, ultrafiltration, a hollow-fiber cartridge) or a phase change that leaves them behind (distillation). This guide ranks six methods by how thoroughly they do that, pairs each with a proven, real-world pick, and is honest about the trade-offs — cost, water waste, counter space and flow rate — so you can match the method to your kitchen and budget.

How Filtration Removes Microplastics — and What Doesn’t Work
Removing a microplastic is a physical problem: the particle has a size, and your method has to put a barrier (or a phase change) in its way that the particle can’t get past. Microplastics are defined as anything under 5 mm, but the ones that matter most are the smallest — down to nanoplastics well below a single micron. That single fact sorts every “water filter” into ones that remove plastic and ones that don’t. Three things decide how well a method works:
Pore size — the whole ballgame. A barrier only strains out particles bigger than its holes. Reverse-osmosis membranes sit around 0.0001 microns, so essentially nothing plastic gets through; hollow-fiber and tight ultrafiltration cartridges run 0.01–0.1 microns, fine enough for microplastics and most nanoplastics. A loose carbon block rated at 1–5 microns, or a pitcher that filters by activated carbon alone, is built for chlorine and taste — not for straining out particles. Look for a stated micron rating or an independent microplastics test, not just the word “filter.”
Mechanism — strain it, or leave it behind. Most methods here physically strain the water (RO, ultrafiltration, hollow-fiber, a tight faucet cartridge). Distillation works the other way: it boils water to steam, which rises and leaves the heavier plastic particles in the boiling chamber, then condenses back to pure water. Both approaches remove the overwhelming majority of plastic; which you pick comes down to flow rate, counter space and whether you want to keep the water’s minerals.
Where the water lands — don’t re-contaminate it. It’s self-defeating to filter microplastics out and then pour the clean water into a plastic jug or carry it in a plastic bottle that sheds its own particles. The best setups collect into a glass carafe or stainless steel. This is also why bottled water isn’t the shortcut it seems — the bottle is itself a major source.
Boiling alone doesn’t filter them out — the particles stay in the water. A 2024 study did find that in hard water, boiling and letting it settle traps a share of plastic inside the limescale that forms, so pouring the cooled water off the scale removes some; in soft water it does almost nothing. Treat it as a free partial step, then still filter. Plain activated-carbon pitchers (the basic ones built for taste) and “alkaline” or “ionizer” gadgets aren’t designed to strain particles and shouldn’t be relied on for microplastics. And bottled water adds plastic rather than removing it. For the full picture, see does boiling water remove microplastics and is tap water safe to drink.
The six methods below are ranked by how thoroughly they remove microplastics — starting with the two that remove the most (reverse osmosis and distillation), then the best permanent under-sink option, the easiest pitcher, the cheapest tap-mounted filter, and a filtered bottle for travel. For deeper roundups by format, see our guides to the best water filters for microplastics, the best reverse-osmosis systems, and the best countertop water distillers.
The 6 Best Ways to Remove Microplastics From Water, Ranked
#1 — AquaTru Carafe Countertop RO — Removes the Most (Reverse Osmosis)
Removes the Most
A real RO system that sits on the counter and plugs in — no under-sink plumbing. The 0.0001-micron membrane removes microplastics and nanoplastics (the particles most likely to reach the bloodstream), plus PFAS, arsenic, nitrates, chlorine, fluoride, and heavy metals — 82+ contaminants in total, certified to NSF/ANSI 58. Filtered water collects in a glass carafe, so the water never touches plastic after it leaves the filter.
The trade-offs are honest: it costs $300+ upfront, the RO process wastes some water, and the carafe refills in about 15 minutes rather than instantly. Filter replacements run roughly $70/year. For most households that want the deepest filtration without a contractor, it is the easiest path to genuinely clean water.
"I am now a complete water snob. All water is inferior and it's not even close." AquaTru owners talk like converts, and the buying pattern backs it up — people get one, then buy more for parents and grown kids. Owners who test with home water-purity meters report readings dropping to single digits, and a common move is buying a second glass carafe so one is always cold in the fridge. The fair warnings from reviews: hard water is its enemy (descale on schedule — damage from skipping it isn't covered), the glass carafe is on the thin side, and a thirsty household will refill the tap-water tank daily.
Reverse-osmosis purity you can set on the counter today — then store the result in glass, never plastic.
Why it's safe: The 4-stage RO membrane is NSF/ANSI 58 certified to remove microplastics, nanoplastics, PFAS, lead, arsenic, and chlorine — and the glass carafe means zero plastic contact at the point of use.

#2 — Megahome Countertop Water Distiller — Distillation Leaves the Plastic Behind
Distills Everything
Megahome has been making this exact machine, unchanged in its essentials, since the early 2000s. The 316L stainless-steel boiling chamber is the medical-grade alloy used in surgical instruments — it resists pitting from long-term boiling far better than the 304 stainless in cheaper units. The porcelain nozzle liner at the top of the boiler is the detail that separates Megahome from most competitors: it stops the vapor from ever touching the exterior painted or plastic coating on the boiler cap, so no coating chemistry ever hitches a ride into the finished water. The real glass collection carafe means the final distilled water — which is chemically aggressive because it has no dissolved minerals — never contacts a polymer.
The math: at 580 watts, one full 4-liter cycle takes about 5.5 hours and produces about 1 gallon of distilled water. Amazon lists the wattage as "580W distilling" (versus 750W in nominal power draw), which is why cycle time is a touch longer than the CO-Z or VEVOR at the same tank size. That trade of speed for gentleness of boil is intentional: a slower, cooler boil produces less steam carryover of volatile organics, which is why the same detail also shows up in H2oLabs's premium distiller.
The honest trade-offs: the Megahome ships with an included activated-carbon post filter that captures VOCs but adds a $12/year consumable to the operating cost. The glass carafe is fragile — dropping it means a full replacement (about $35 from Megahome). And the total wattage over a full year of daily distilling adds ~$150 to your electric bill at U.S. average rates. If those trade-offs are unacceptable, the H2oLabs 300SS is the "no compromises" upgrade; if the glass carafe is the deal-breaker, the CO-Z 4L or VEVOR 4L glass-jug variant is a cheaper path to the same benefit.
Long-time owners consistently praise the Megahome's simplicity — "no electronics to break." Owners with hard water report the boiler pot showing chalky mineral deposits after every cycle (that's the point, it's the contaminants you would have drunk) and appreciate that a monthly citric-acid rinse restores it to like-new. The honest gripes that repeat: the fan is audibly noisier than the H2oLabs, the plastic top-cap latch feels less premium than the price, and the porcelain nozzle liner can chip if the boiler pot is dropped during cleaning. Replacement glass carafes are readily available.
The only sub-$275 countertop distiller with a 316L medical-grade stainless boiler AND a real glass collection carafe — no plastic touches your finished distilled water.
Why it's safe: 316L stainless steel is the alloy used in medical implants, and the porcelain-lined nozzle isolates the vapor from any external coating chemistry — a Megahome is the same appliance sold in dental and pharmaceutical labs.

#3 — Waterdrop TSU Ultrafiltration — Best Permanent Under-Sink Filter
Best Under-Sink
The Waterdrop TSU pairs a 5-micron sediment/carbon pre-filter with a proprietary 0.01-micron ultrafiltration (UF) hollow-fiber membrane and a post-carbon polishing stage. That 0.01-micron rating is 50× tighter than a typical 0.5-micron carbon block — small enough to physically block bacteria (E. coli, cryptosporidium cysts) and every microplastic ever measured in drinking-water studies, which bottom out around 1 micron. Unlike RO, the UF membrane does not strip dissolved minerals, so calcium, magnesium, and fluoride pass through and the water still tastes like water.
The membrane is rated for up to 16,000 gallons — roughly 3 years for a typical family — which makes long-term cost per gallon far lower than the Aquasana. Twist-and-lock cartridge changes take under 30 seconds and no tools. Installation is standard under-sink with a dedicated faucet included.
The honest trade-offs: Waterdrop's certifications are at the component level (NSF 42-tested materials) rather than a full system-level NSF/ANSI 401 seal like the Aquasana, so if certification-on-paper matters most to you, the Aquasana still wins. Also, UF alone does not reduce lead as thoroughly as a lead-certified carbon block — if your home is on a lead service line, the Aquasana or Frizzlife MK99 (both lead-certified) is the safer buy.
Owners rave about how quickly they can swap cartridges — most describe it as one twist, no tools, no water shutoff needed thanks to the built-in shutoff valves. Well-water and older-plumbing users say the difference in taste and clarity is dramatic. The honest gripes: the plastic cartridge housing can develop a hairline seep at the top O-ring after a couple of years if you overtighten during installation, and Waterdrop's marketing headline of "1,000+ contaminants removed" is broader than the third-party certifications actually cover — the real proof point is the UF membrane's particle size, not the marketing.
A 0.01-micron UF membrane physically blocks microplastics and bacteria — 50× tighter than a standard carbon block, with 3-year cartridge life and no waste water.
Why it's safe: The ultrafiltration membrane's pore size is smaller than any microplastic ever measured in a drinking-water study — so particles are physically excluded, not just adsorbed onto carbon.

#4 — Epic Pure Pitcher — Easiest, No Installation Needed
Easiest / Best Pitcher
Owners credit it for genuine protection, repeatedly citing removal of "99.999% of over 200 tap water contaminants" including fluoride, PFAS, and microplastics — the recurring theme is real filtration versus big-box brands, and one owner summed the taste up as "It tastes sooo good." In timed tests it filters a full 10-cup pitcher in about 11 minutes. The honest downsides: slow flow is the most common gripe and it worsens as the cartridge saturates, untreated water in the top reservoir can spill into the lower chamber if you lift the pitcher while completely full, and buyers report cracked plastic and lid problems at a price above mainstream brands.
The clearest evidence on this list: Epic posts its independent lab results publicly, so you can see the 99.9% microplastic-removal data instead of trusting a slogan on the box.
Why it's safe: The hollow fiber membrane physically blocks microplastic particles down to ~1 micron, while the carbon stage handles chlorine, lead, and PFAS — all in a BPA-free Tritan body.

#5 — Waterdrop WD-FC-06 Faucet Filter — Cheapest Way to Filter at the Tap
Cheapest at the Tap
Waterdrop's WD-FC-06 competes with the PUR Plus on a different axis: durability. The full body is 304 food-grade stainless steel, so it will not yellow, crack, or degrade like a plastic housing after a couple of years in a hot sunny kitchen. Independent testing puts it at the top of the faucet-filter category for chlorine reduction and clocks its flow rate at 1.3 gallons per minute — slightly faster than every plastic-housing filter. The included cartridge is rated for up to 12 months at typical usage, which is a big deal for reducing annual maintenance cost.
Two honest trade-offs. First, the WD-FC-06 has NSF-certified components but is not system-certified to NSF/ANSI 42/53/401 the way the PUR Plus is — so the specific "99% lead" and "certified microplastic" claims do not apply. It is a general chlorine, sediment, and heavy-metal filter, not a specifically-lead or specifically-microplastic tool. Second, replacement cartridges are noticeably more expensive than Brita or Culligan cartridges, so the "cheap per gallon" advantage narrows over multiple years.
Buyers repeatedly single out the build quality: it feels like a real fixture instead of a temporary attachment. The 360-degree swivel is called out as an underrated feature — you can direct the filtered stream at the sink or a pot without unscrewing anything. The honest downsides: replacement filters are called "ridiculously expensive" by more than one reviewer relative to Brita cartridges; the diverter tab is small and requires a firm push; and some faucets with unusual thread pitches need an add-on adapter that Waterdrop should include but does not.
A full stainless-steel faucet filter that will still look and work in five years, with 12-month cartridges and 360-degree rotation.
Why it's safe: A 304 food-grade stainless-steel housing (no plasticizer leaching) plus NSF-certified carbon-block cartridge that reduces chlorine, heavy metals, and taste/odor at 1.3 GPM.

#6 — Clearly Filtered Insulated Bottle — Remove Microplastics on the Go
Best On the Go
Clearly Filtered is a US brand whose stationary pitcher is one of the most independently-tested consumer filters on the market. The insulated stainless bottle brings the same six-media Affinity Filtration block into a 20 oz double-wall vacuum-insulated body. Clearly Filtered publishes lab test data showing the bottle cartridge reduces lead by more than 99.34% (at pH 6.5) and fluoride by 99.52%, and states that its filter media line (bottle, pitcher, under-sink) reduces microplastics by more than 99.9%, PFOA by more than 99.0%, PFOS by more than 99.5%, and GenX by more than 99.4%. The company describes its bottle as "independently tested to comply with NSF/ANSI Standards 42, 53, 401, and 473."
Cartridge life is short — about 25 gallons or 160 fills (roughly 4 months of daily use), and replacement cartridges are around $30 each, which puts long-term cost per gallon at roughly $1.20 — the highest in this roundup. The body is 18/8 stainless steel, BPA/BPS/phthalate-free, with a silicone straw, and everything is built in the USA. Clearly Filtered publishes a lifetime warranty on the bottle body.
The honest trade-offs: tested to comply with is not the same as NSF-certified by, and the specific bottle SKU's microplastic and PFAS percentages come from the company-wide filter-media test line rather than the bottle QFT report specifically — if you want a fully third-party NSF-certified filter, the Aquasana AQ-5300+ under-sink in our under-sink guide is a better fit. Flow through the straw is slow; the premium price is real; and it is a filter, not a purifier, so no viruses.
Owners with hard water or high-fluoride wells consistently describe an immediate taste change — "no more chalky aftertaste" — and the double-wall insulation keeping ice water cold for 24 hours. Long-term owners praise the lifetime warranty and USA build quality. Recurring gripes: the $30-per-cartridge replacement cost adds up, the 25-gallon life is short, the flow slows noticeably in the last few weeks of a cartridge's life, and the lid design has been redesigned once due to earlier leak complaints (older reviews reflect the older lid).
The widest published contaminant-removal list of any filter bottle — lead, fluoride, PFAS, microplastics — in an insulated stainless body built in the USA.
Why it's safe: Clearly Filtered publishes company-wide test-to-standard data across NSF/ANSI 42, 53, 401 and 473 protocols; bottle-specific test data is published for lead and fluoride reduction.

What Doesn’t Reliably Remove Microplastics From Water
Knowing what to skip saves money and prevents a false sense of security. These popular moves do little or nothing about microplastics on their own:
- Buying bottled water: the single most expensive mistake. Testing has repeatedly found more plastic in bottled water than in tap — the 2024 PNAS study counted roughly 240,000 particles per liter, most of it shed from the bottle and cap. You’re paying a premium to drink the container.
- A basic activated-carbon pitcher: the standard taste-and-chlorine pitcher is not built to strain out particles and has no published microplastics rating. If a pitcher doesn’t state a micron size or an independent microplastics test, don’t assume it removes plastic.
- Boiling alone: boiling kills microbes but doesn’t filter plastic out — the particles stay in the water. In hard water, boiling and settling can trap some particles in the scale, but that’s a partial free step, not a filter.
- “Alkaline,” “ionizer” and “structured water” gadgets: these change pH or marketing claims, not particle count. None is designed to physically remove microplastics.
- Filtering, then storing in plastic: pouring clean water into a plastic jug or carrying it in a plastic bottle re-introduces shedding particles. Collect and store in glass or stainless steel.
The bottom line: to actually remove microplastics you need pore size (reverse osmosis, ultrafiltration, a hollow-fiber or tested multi-stage cartridge) or a phase change (distillation) — then keep the clean water out of plastic.

Which Method Is Right for You?
- You want to remove the most, counter space is fine: AquaTru Carafe RO — reverse osmosis strips essentially all microplastics plus PFAS, lead and more, into a glass carafe. Remineralize or eat a normal diet for minerals.
- You want “remove everything” without plumbing or water waste: Megahome Countertop Distiller — distillation leaves plastic (and nearly all contaminants) behind in the chamber; the glass collection carafe keeps the result plastic-free.
- You want a permanent, high-flow kitchen filter that keeps minerals: Waterdrop TSU Ultrafiltration — 0.01-micron membrane catches microplastics at full tap speed with no drain water, from a dedicated faucet.
- You want the easiest, cheapest start: Epic Pure Pitcher — a hollow-fiber pitcher tested to remove 99.9% of microplastics, no installation at all.
- You rent, or want the lowest-cost tap option: Waterdrop WD-FC-06 Faucet Filter — screws onto most faucets in minutes and comes off when you move.
- You want clean water away from home: Clearly Filtered Insulated Bottle — a stainless bottle whose multi-media filter removes microplastics on the go, so you’re not buying bottled water.
"Removing a microplastic is a physics problem, not a branding one. If the barrier’s pores are smaller than the particle, it’s gone — reverse osmosis and distillation remove the most, and a tested hollow-fiber filter is the easy everyday answer. A plain carbon pitcher and a case of bottled water are the two things people reach for that don’t do the job."
How We Ranked These Methods
We ranked by how thoroughly each method removes plastic particles first, then by cost and effort:
- Pore size / mechanism: the smaller the effective pore (or the cleaner the phase change), the more completely microplastics and nanoplastics are removed. Reverse osmosis (~0.0001µm) and distillation lead; 0.01-micron ultrafiltration and hollow-fiber cartridges follow.
- Evidence it works: we favored products with a stated micron rating, an NSF listing, or published independent microplastics testing over vague “filters contaminants” claims.
- No re-contamination: units that collect into glass or stainless (rather than reintroducing plastic) ranked higher, since the point is to stop drinking plastic.
- Cost, effort and flow: upfront price, filter replacement cost, installation, counter space, water waste and how fast you get a glass — because the best method is the one you’ll actually run every day.
- Keeps minerals (where it matters): ultrafiltration, hollow-fiber and faucet filters leave healthy minerals in; RO and distillation strip them, so we noted when remineralizing makes sense.
We left out “alkaline” and ionizer gadgets, structured-water devices, and plain taste-only carbon pitchers, none of which is designed to strain out particles. And we treated bottled water as a source of microplastics, not a solution.

Frequently Asked Questions
Reverse osmosis is the most thorough method. Its membrane has pores around 0.0001 microns, far smaller than the smallest microplastics and most nanoplastics, so it removes well over 99% of plastic particles along with PFAS, lead and other contaminants. Distillation is comparable because it boils water to steam and leaves the plastic behind in the chamber. If you want one device that removes the most, choose a reverse-osmosis system or a countertop distiller with a glass collection carafe, so the purified water is never stored back in plastic.
Boiling does not filter microplastics out on its own — the particles stay in the water. But a 2024 study found that in hard water, boiling then letting the water settle can trap a large share of plastic particles inside the limescale that forms, so pouring the cooled water off the scale removes some of them. It is a partial, free fallback, not a substitute for filtration, and it does nothing in soft water. If you do try it, boil in a glass or steel kettle rather than a plastic one — a plastic electric kettle can shed its own particles into the water as it heats, working against the point. To actually remove microplastics, pour the boiled, settled water through a filter.
Only the right ones. A plain activated-carbon pitcher is designed for taste and chlorine and does not reliably catch microplastics. Pitchers with a hollow-fiber membrane or a very tight multi-stage cartridge — such as the Epic Pure — are independently tested to remove upwards of 99.9% of microplastics, because the physical pore size is small enough to strain the particles out. Check for a stated micron rating or an NSF/third-party microplastics test before trusting a pitcher to do it.
No — bottled water generally contains more. A 2024 study using advanced imaging found roughly 240,000 plastic particles per liter in popular bottled waters, most of them nanoplastics shed from the plastic bottle and cap. Filtering your own tap water with reverse osmosis, a distiller or a hollow-fiber filter and storing it in glass or stainless steel removes far more plastic than buying bottled water does, and it costs a fraction as much over time.
