AquaTru vs Brita

Neither one is NSF certified, and both are certified

This trips up almost everyone. AquaTru is certified by IAPMO R&T. Brita’s pitcher filters are certified by WQA. Neither appears in NSF International’s database for most of its claims, and neither is worse for it.

NSF International, IAPMO R&T and WQA are three separate accredited certification bodies, and all three certify products against the NSF/ANSI standards. The standard is the yardstick; the body is who measures against it. So “NSF/ANSI 53 certified” tells you which test was applied, and the certifier’s name tells you who applied it.

We nearly got this wrong ourselves. A search of NSF’s database returns just two records for Brita, both for lead. Brita’s full claim set, nineteen contaminants under NSF/ANSI 53 and sixteen more under 401, sits with WQA. Searching one database and concluding a product is uncertified is the single most common mistake in this category.

What each one is certified to remove

Sourced from IAPMO R&T files W-10188, W-10193, W-10194 and W-10195 (AquaTru, LLC), the WQA product listings for Brita LP, and the NSF listings for The Brita Products Company. All current as of 7 September 2026. WQA’s listing covers Brita’s filter range without splitting claims by cartridge, and Brita states the Elite covers around three times as many contaminants as the Standard, so check which filter you are buying.

On pharmaceuticals and microplastics, they are the same

Both hold NSF/ANSI 401 certification, and the claim lists match compound for compound: atenolol, bisphenol A, carbamazepine, DEET, estrone, ibuprofen, linuron, meprobamate, metolachlor, naproxen, nonylphenol, phenytoin, TCEP, TCPP, trimethoprim and microplastics.

Sixteen claims each, from two different certification bodies, on products separated by a factor of ten in price. If pharmaceutical residues or microplastics are what worry you, the $35 pitcher is certified to do exactly what the $375 countertop system is certified to do.

That is worth knowing before you upgrade. Our microplastics guide covers which products across the market carry that claim, and Brita is the only pitcher on the list.

Where AquaTru pulls ahead

Three things, and they are the reason to spend the money.

PFAS

AquaTru is certified for PFOA and PFOS under NSF/ANSI 53. No Brita listing carries any PFAS claim, in any database. If your utility has reported PFAS, or you live near a known source, this alone settles it. Our PFAS filter guide covers the wider field.

The reverse osmosis claims

Fluoride, arsenic, nitrate, TDS, radium, perchlorate, selenium and barium all sit on AquaTru’s NSF/ANSI 58 certificate, and the ATU200 under-sink model adds uranium. Those are reverse osmosis claims; a carbon pitcher cannot make them, and Brita does not. If your water comes from a well, or your report flags nitrate or arsenic, that is decisive.

Filter life

AquaTru is certified to 300 gallons on the Carafe and 600 on the Classic. Brita’s Elite filter is certified to 120 gallons, and the Standard to 40. For a household drinking two gallons a day, that is roughly ten months against two, or three weeks on the Standard filter.

What the pitcher does that the countertop does not

Brita’s NSF/ANSI 53 certificate names nineteen contaminants, including mercury, cadmium and asbestos, which do not appear on any AquaTru listing we could find. It also names thirteen individual pesticides and volatile organics.

AquaTru covers most of that ground differently. Its NSF/ANSI 53 certificate carries the elective VOC claim, which under that standard means the product reduces a list of roughly fifty named compounds including atrazine, benzene, toluene and 2,4-D. So on organics AquaTru’s single claim is broader, even though Brita’s list looks longer.

Mercury, cadmium and asbestos are the genuine gaps. If those appear on your water report, Brita is certified for them and AquaTru is not.

Which one should you buy?

Best overall

AquaTru

Countertop reverse osmosis, no plumbing required

Certified by IAPMO R&T under NSF/ANSI 58 for lead, fluoride, arsenic, TDS, radium, perchlorate, nitrate, selenium and barium; under 53 for PFOA, PFOS and VOC; under 401 for microplastics and fifteen compounds; under 42 for chlorine, chloramine and particulate class I. 300 to 600 gallons.

Buy this if your water report names PFAS, fluoride, arsenic or nitrate, or if you are tired of changing a filter every few weeks. Four certificates, around twenty certified claims, and 600 gallons on the Classic.

The Carafe is the AT100 family at 300 gallons and suits one or two people. The Classic is the AT2000 family at 600. Reviews of the Carafe and the Classic.

Better than its reputation

Brita with the Elite filter

Pour-through pitcher, WQA certified

Certified by WQA under NSF/ANSI 53 for lead, mercury, cadmium, copper, asbestos and thirteen named pesticides and organics; under 401 for microplastics and fifteen compounds; under 42 for chlorine, chloramine, taste and odour, zinc and particulate classes I and VI; and under NSF/ANSI/CAN 372 for lead-free materials.

Keep this, or buy it, if lead, chlorine, taste, pharmaceuticals or microplastics are your concerns. Brita is certified for all of them, and the 401 list is identical to AquaTru’s. For a $35 pitcher that is a genuinely strong position, and better than the brand’s reputation among filter enthusiasts suggests.

Two caveats. There is no PFAS claim anywhere on Brita’s listings, and no fluoride, arsenic or nitrate. And the Elite filter is certified to 120 gallons against the Standard filter’s 40, so make sure you are buying the Elite. Our Brita Elite review has the detail.

Should you upgrade from a Brita?

Only if your water report says so. That is a less exciting answer than most comparison pages give, and it is what the certificates support.

Get a copy of your utility’s annual water quality report, or test your water. If it flags PFAS, fluoride, arsenic, nitrate or uranium, Brita is not certified for any of them and AquaTru is. If it flags lead, chlorine, disinfection byproducts, pharmaceuticals or microplastics, your Brita with an Elite filter is already certified to handle them.

The one non-contaminant reason to upgrade is filter changes. Two months against ten is a real quality-of-life difference, and over several years the running cost gap narrows more than the sticker price suggests.
