Quick Answer

Partly. A Brita pitcher uses activated carbon plus an ion-exchange resin, which will physically trap the larger microplastic particles by size exclusion as water passes through. But standard Brita filters are certified to NSF/ANSI 42 and 53 (chlorine taste/odour, and metals like lead on the Elite filter), not to NSF/ANSI 401, the standard that includes a microplastics claim. So Brita is not tested or marketedas a microplastics filter, the smallest particles and nanoplastics pass through, and performance falls off as the cartridge loads up. If clean taste and some lead reduction are the goal, Brita is fine. If microplastics are specifically your priority, a solid carbon block certified to NSF 401, a multi-stage system like ZeroWater, or reverse osmosis will outperform a Brita pitcher meaningfully.

Key Takeaways

Brita filters remove the bigger microplastic particles by size exclusion, but are not certified (NSF/ANSI 401) or marketed as microplastics filters.
Standard Brita targets NSF 42 (chlorine, taste/odour); Brita Elite adds NSF 53 lead reduction and lasts ~6 months. Neither publishes a microplastics removal figure.
Microplastics span 1 µm to 5 mm. Loose-granule carbon pitchers catch the coarse end; sub-micron particles and nanoplastics slip through.
For a microplastics-first choice: a dense carbon block certified to NSF/ANSI 401, ZeroWater's 5-stage system, or reverse osmosis all outperform a Brita pitcher.
The Brita reservoir is BPA-free plastic holding cold water at room temperature, so the pitcher itself sheds little; a glass or stainless dispenser removes even that.

How a Brita filter actually works, and where it stops

A Brita pitcher cartridge is two materials doing two jobs. The activated carbon adsorbs chlorine and the organic compounds that cause off-tastes and odours. The ion-exchange resin swaps out metal ions, the Elite cartridge is certified to reduce lead. Neither of those jobs is “remove microplastics.” What removes microplastics is physical size exclusion: a particle too big to fit through the media gets caught.

That is why the answer is “partly.” Microplastics are not one size, they run from 5 millimetres all the way down to 1 micron, and nanoplastics smaller still. A loose-granule carbon pitcher has relatively large, uneven flow paths between the granules, so it reliably catches the coarse particles and progressively less as the particles get smaller. A dense extruded carbon block, the kind used in filters certified to NSF/ANSI 401, has a much finer, more uniform pore structure and captures a far larger share of the small end. Brita's standard pitcher is not that.

Common household filters vs microplastics (2026)
Filter	Technology	Certification	Microplastics	Verdict
Brita Standard	Carbon granules + resin	NSF 42	Coarse particles only	Taste, not microplastics
Brita Elite / Longlast+	Denser carbon + resin	NSF 42 & 53 (lead)	Better, still uncertified	Good all-rounder
ZeroWater (5-stage)	Carbon + ion exchange	NSF 42, 53, 401 (models)	Strong particulate removal	Stronger for microplastics
Clearly Filtered	Multi-stage affinity	Tested to NSF 401/473	Publishes ~99% MP data	Microplastics-first pitcher
Reverse osmosis	Sub-micron membrane	NSF 58	Micro + most nanoplastics	Gold standard

What the MicroPlastics app checks

The polymer and packaging of the bottled waters and drinks you scan, so you can see what you're filtering out, and what you're re-adding after.
A 0–100 microplastic risk score per product, so “filtered tap in a glass” can be compared against “bottled water in PET.”
Lower-plastic swaps for the containers you store and drink filtered water from (glass and steel over plastic).
A running exposure log so you can tell whether switching filters or bottles is actually moving your overall number.

Use the App

Filtering tap is only half the equation

A great filter does nothing if you pour the water into a plastic bottle that sheds on the way to work. Scan your bottled waters, your filter pitcher, and your daily bottle to see where the plastic actually re-enters.

So should you keep your Brita?

For most people, yes, with realistic expectations. A Brita meaningfully improves taste, cuts chlorine, and (on the Elite cartridge) reduces lead, and it will strip out the larger microplastic particles as a side effect. That is a genuine upgrade over unfiltered tap and far better for the planet than bottled water in PET, which carries its own microplastic load. Three ways to get more out of it:

Use the Elite/Longlast+ cartridge, not the standard. Denser media, lead certification, and a 6-month life mean better and more consistent particulate capture.
Change the cartridge on schedule. A loaded filter channels water around exhausted media and its particulate capture drops. Late changes are the most common reason a filter underperforms.
If microplastics are the specific priority, step up a tier. A pitcher certified to NSF/ANSI 401 (ZeroWater, Clearly Filtered) or an under-sink reverse-osmosis system is the honest answer. Brita is a taste-and-lead filter that helps with microplastics, not a microplastics filter that also improves taste.

Frequently Asked Questions

Do Brita filters remove microplastics?

Partly. Brita’s activated-carbon-and-resin cartridges trap the larger microplastic particles by size exclusion, but Brita filters are certified to NSF/ANSI 42 and 53 (taste, chlorine, and metals like lead), not to NSF/ANSI 401, the standard that carries a microplastics claim. The smallest particles and nanoplastics pass through, so Brita reduces but does not reliably remove microplastics.

Is Brita Elite better than standard Brita for microplastics?

Yes. The Elite (formerly Longlast+) cartridge uses denser media, is certified for lead reduction under NSF 53, and lasts about six months. The denser, longer-life media captures more fine particulate than the two-month standard filter, though Brita still does not publish a microplastics removal percentage for either.

What filter removes the most microplastics?

Reverse osmosis is the gold standard, its sub-micron membrane excludes microplastics and most nanoplastics. Among pitchers and countertop units, look for NSF/ANSI 401 certification: ZeroWater’s 5-stage system and Clearly Filtered publish strong microplastics data. A dense carbon block outperforms a loose-granule pitcher like Brita.

Does the Brita pitcher itself add microplastics?

Minimally. The reservoir is BPA-free plastic holding cold water at room temperature, the low-heat, low-acidity conditions where plastic sheds least. If you want to remove even that variable, Brita and others sell glass and stainless dispensers, or you can decant filtered water into a glass carafe.

Does boiling water remove microplastics instead?

Boiling can cause some microplastics to bind with limescale in hard water, which then settles out, but it does not reliably remove them and can fragment particles. It is not a substitute for filtration. Use an appropriate filter and store the water in glass or stainless steel.
