'Not certified for' means this filter's performance data sheet shows no certified claim for that compound. NSF/ANSI 53 and NSF/ANSI 58 have a test for it, but this model is not certified to it, so we cannot tell you how it performs on that compound.

PFAS compounds Washington Township MUA reported, and this filter's certification status for each
How to read this table: 'Highest level reported' is the single highest result in the dataset for that sampling point, not a yearly average. The legal limit is judged on a running yearly average at each sampling point. The certification pass level is the most a filter may leave in its treated water during the lab test; for PFOA and PFOS it applies to the two combined. The standard sets it, not the legal limit. These numbers come from different tests, so we do not subtract one from another or estimate what a filter would leave in your water.
In a "Not detected" note, the amount after "as published" is the same reporting level in the unit EPA's data uses.

Tested, not detected at or above the reporting level
These compounds were tested and not detected at or above the reporting level at any sampling point, so they have no row in the table above.

Certified claims, with their sources
PFOA: certified to reduce
Certified to NSF/ANSI 53 for PFOA/PFOS by WQA under Aquasana, Inc., AQ-5300+.
Legal limit: EPA MCL (2024 rule, 89 FR 32532): 4 ppt for PFOA. NSF/ANSI 53 combined PFOA + PFOS pass level: 70 ppt.
Rated life: 800 gallons (data sheet).
Manufacturer performance data sheet (PDF) Version date not printed on the data sheet; retrieved 2026-10-20.
PFAS compounds we do not score, and why
- PFHxA and PFPeA, for each compound: NSF/ANSI 53 and 58, the standards EPA points to for PFAS reduction, set reduction requirements for seven PFAS in their 2022 editions: PFOA, PFOS, PFHxS, PFNA, PFHpA, PFBS and PFDA. This compound is not one of them, and no filter we track is certified for it, so we do not score it.
The filter this page is about

Aquasana AQ-5300+ (replacement cartridge AQ-5300+R): PFAS certification
Read before acting on these numbers
- Levels are utility-reported results; your tap may differ.
- Certified performance applies within the filter's rated capacity: 800 gallons.The certification applies to the first 800 gallons through each cartridge; past 800 gallons, it does not apply to that cartridge.
- A certification pass level is the maximum concentration allowed in the test's treated water. It is set by the standard, not by the legal limit, and may be above the limit.
- Results are shown with the dates they were sampled. Utilities add treatment over time; check the date before acting on a number.
Words on this page
- PFAS
- per- and polyfluoroalkyl substances, a large group of manufactured chemicals.
- Compound names
- short names of individual PFAS chemicals, such as PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid).
- ppt
- parts per trillion, the unit used here for PFAS results and limits. 1,000 ppt equals 1 part per billion (ppb).
- µg/L
- micrograms per liter, the unit EPA's UCMR 5 data uses. In drinking water 1 µg/L equals 1,000 ppt, so 0.004 µg/L is 4 ppt.
- Reporting level
- the lowest amount EPA set for labs to report as a number in UCMR 5 testing (EPA calls it the minimum reporting level). A result below it is listed as not detected at or above the reporting level, which does not mean zero.
- PWSID
- Public Water System ID: the number EPA and the state use to identify a public water system.
- UCMR 5
- UCMR 5 (also written UCMR5): EPA's fifth Unregulated Contaminant Monitoring Rule, under which public water systems tested for PFAS and lithium starting in 2023. Each result on this page shows its sample dates.
- EPA MCL
- Maximum Contaminant Level: the federal legal limit for a public water system, judged on a running yearly average at each sampling point. "(2024)" is the year EPA issued the PFAS rule.
- NSF/ANSI 53
- NSF/ANSI 53 (Drinking Water Treatment Units – Health Effects): a standard for home drinking water filters. Its 2022 edition sets PFAS reduction requirements for seven compounds: PFOA, PFOS, PFHxS, PFNA, PFHpA, PFBS and PFDA.
- NSF/ANSI 58
- NSF/ANSI 58 (Reverse Osmosis Drinking Water Treatment Systems): a standard for home reverse osmosis systems. Its 2022 edition sets PFAS reduction requirements for the same seven compounds.
- Pass level
- the most of a compound the standard allows in the filter's treated water during the lab test (for PFOA and PFOS, the two combined). The standard sets it, not the legal limit.
- Certified
- a certifier lists this model as meeting a standard's requirements for that compound. It describes a lab test, not a measurement of your water.
- Certification claim
- a reduction claim a standard offers, with its own lab test and pass level. Most are for one compound; for PFOA and PFOS, the claim is for the two combined. A filter model is certified only for the claims its certifier lists it for.
- WQA
- the Water Quality Association, a trade association that also runs an accredited program certifying water treatment products.
- Sampling point / entry point
- the place a sample was taken. An entry point is where treated water enters the distribution pipes, usually at a treatment plant. Neither is your tap.
- Hazard Index
- under EPA's April 2024 PFAS rule, the limit for mixtures of PFHxS, PFNA, HFPO-DA (GenX) and PFBS, which counts these compounds together rather than one at a time. EPA published a proposal to remove it on May 20, 2026 (91 FR 29413); the proposal is not final.
- Proposed rule
- a change EPA has published for public comment but has not adopted. A proposed rule does not change any current limit.
- Federal Register (FR)
- the U.S. government's official daily publication of federal rules, proposed rules and notices. "89 FR 32532" means volume 89, starting at page 32532.
- Code of Federal Regulations (CFR)
- the official collection of federal rules in effect, arranged by subject. As part of each status check we read the PFAS limits in its continuously updated online version, the eCFR (40 CFR 141.61(c)(2)).
- HFPO-DA (GenX)
- hexafluoropropylene oxide dimer acid, a PFAS compound often called GenX.
- Dataset
- the published set of results a number comes from, named in the Dataset column.
- Filters we track
- the filters whose manufacturer performance data sheets we have entered. A filter not on our list may still be certified; we do not have its data.
- Score
- to say which filters we track are certified to reduce a compound.
- Performance data sheet
- the manufacturer's document listing a filter's certified claims, pass levels and rated life; it is our source for every certified claim.
- Rated life
- how much water a cartridge is certified to treat, from its data sheet; certified performance applies only within it.
- MUA
- municipal utilities authority, a local public agency that provides water service, sewer service or both.
- TP
- in a sampling-point name, short for treatment plant.
