The short answer

Aquasana sells both answers. The Rhino, the whole house system the brand is famous for, does not remove PFAS in any certified sense. It carries no PFAS certification, its testing stops at chlorine, and Aquasana does not position it as a PFAS product. The HealthShield, the newer and more expensive whole house system, does. It is WQA tested and certified to NSF/ANSI Standard 53 for five named PFAS compounds, with a certified reduction of up to 99.9 percent down to below 4 parts per trillion.

So the honest answer to the question in the title is: not the Rhino, yes the HealthShield, and yes with a catch on price. If you came here because your water report mentions PFAS and you already own or are eyeing a Rhino, the sections below explain why the distinction matters and what to buy instead. For the background on the chemicals themselves, see our guide to PFAS in drinking water, and for the full field of options see our picks for the best water filter for PFAS.

PFAS in plain words

PFAS is short for per and polyfluoroalkyl substances, a large family of manufactured chemicals used in nonstick coatings, stain resistant fabrics, food packaging, and firefighting foam. They are nicknamed forever chemicals because they break down extremely slowly, so they persist in soil and water and build up in people over time.

The scale involved is hard to picture. PFAS in drinking water is measured in parts per trillion, and the EPA enforceable limit for the two most studied compounds, PFOA and PFOS, is 4 parts per trillion each, with a health goal of zero. That context matters for filter shopping, because a claim like 90 percent reduction sounds strong until you ask 90 percent of what, down to what level, and tested by whom. Those questions lead straight to certification, which is where the Rhino and the HealthShield part ways.

The Rhino: no, and it was never built for this

The Rhino is a chlorine machine. Its dual tank design pushes water up through activated carbon and copper zinc filter media, and it is independently tested to NSF/ANSI Standard 42 to reduce 97 percent of chlorine across a 1,000,000 gallon life. Standard 42 is the aesthetic standard: taste, odor, and chlorine. It says nothing about health contaminants like PFAS or lead.

The Rhino's other certification, WQA certification to NSF/ANSI/CAN Standard 61, covers material safety. It confirms the tank itself does not leach anything harmful into your water. It is not a filtration performance claim, and it does not speak to PFAS at all.

Could the Rhino's carbon catch some PFAS on the way through? Activated carbon can adsorb some PFAS compounds, especially long chain ones like PFOA and PFOS, and that is true of almost any large carbon tank. But Aquasana makes no PFAS claim for the Rhino, no certifier has tested it for PFAS, and carbon performance against PFAS fades as the media loads up with everything else in your water. A filter that might reduce some PFAS, sometimes, by an untested amount, is not a PFAS filter. Our Aquasana Rhino review covers what the system genuinely does well, and chlorine removal for a decade is a real strength. PFAS is just not on its list.

One more point for existing owners: buying a Rhino because a salesperson or a listing mentioned forever chemicals would be a mistake, and so would assuming your current Rhino is quietly handling them. It is not certified to, and Aquasana itself steers PFAS buyers to a different product.

The HealthShield: yes, with a certification you can check

The HealthShield is the Aquasana built for this question. It is a single tank whole house system with three layers of specialized media: one aimed at chlorine and chloramine, one engineered for PFAS reduction including harder to catch short chain compounds, and one that takes VOCs, BPA, ibuprofen, and more PFAS. Aquasana counts 61 contaminants in total.

The claim that matters is the certified one. The HealthShield is WQA tested and certified to NSF/ANSI Standard 53, the health effects standard, to reduce five PFAS compounds: PFOA, PFOS, PFHxS, PFNA, and PFHpA. The certified reduction is up to 99.9 percent, bringing those compounds below 4 parts per trillion, which lines up with the EPA limit for PFOA and PFOS. The same Standard 53 certification covers VOC reduction at 99.8 percent, and a separate NSF/ANSI 401 certification covers BPA and ibuprofen at 94.7 percent. Chlorine and chloramine reduction, by contrast, are Aquasana's own internal test numbers at about 97.4 percent, and we label them that way.

Now the honest limitations, because this system has real ones. The tank is rated for 165,000 gallons or about 2 years, a fraction of the Rhino's 1,000,000 gallon life, and the replacement tank costs about $1,749. Flow is rated at 5.7 GPM, the lowest in our whole house roundup, so large homes running several fixtures at once should size carefully. The system also needs a standard power outlet nearby for its flow monitor, and the warranty is 2 years, short for a $2,099 system. You are paying for certified PFAS reduction at every tap, and the running costs are the price of that certification.

If you only need the drinking tap covered

Whole house PFAS treatment is the expensive route, because it filters shower and laundry water too. If your concern is what you drink and cook with, Aquasana's SmartFlow reverse osmosis system is the cheaper certified answer. It is an under sink unit for a single faucet, and it is tested and certified by WQA to NSF/ANSI Standards 42, 53, 58, and 401 for 90 contaminants, including PFOA and PFOS under the Standard 53 certification. Aquasana notes that its Standard 53 certification follows the updated, stricter protocol for PFOA and PFOS testing.

Aquasana also still supports its earlier OptimH2O whole house system, which is certified to reduce lead, cysts, and PFOA and PFOS, and sells replacement filters for it. The HealthShield has taken over as the flagship PFAS whole house model, so new buyers should compare against the HealthShield first.

The tradeoff is scope. A reverse osmosis unit protects one tap, usually the kitchen. It does nothing for the water in your shower, your washing machine, or your bathroom sinks. Whether that matters is a judgment call about exposure routes, but the price gap is large enough that many households reasonably choose the tap and pocket the difference.

Why certification matters more than a percentage

Every filter brand can print a big reduction percentage. The number alone tells you almost nothing, for three reasons.

First, a percentage without a starting level is empty. Reducing PFOA by 99 percent from a very dirty test sample still needs a finish line, and the finish line that matters is the EPA limit of 4 parts per trillion. The HealthShield claim is stated the right way: a percentage and an end point, below 4 parts per trillion.

Second, maker testing is not certification. When a brand tests its own product, it picks the flow rate, the water chemistry, and when to stop the test. Certification under NSF/ANSI 53 means an outside body, in this case WQA, ran the standard protocol, tested the system across its rated capacity and rated flow, and keeps the product in a public listing with ongoing audits. A claim you can look up in a certifier's directory is a different class of claim from a claim on a sales page.

Third, capacity is where PFAS claims quietly die. Carbon that grabs PFAS when fresh may stop grabbing it long before the tank's headline life is over. Certified ratings are tied to a stated capacity, 165,000 gallons for the HealthShield, and the claim only holds inside that window. That is also why the flow monitor on the HealthShield is more than a gadget: it tells you when you are leaving the certified window.

Our rule across this site is simple. If a contaminant worries you enough to spend money on it, buy the claim with a certification listing behind it, and treat everything else as marketing.

Who it is for

Homes whose water report actually shows PFAS, especially PFOA or PFOS near or above the EPA limits, and who want certified reduction at every tap rather than one faucet. Buyers already in the Aquasana ecosystem who assumed the brand's flagship covered PFAS and need the correct model name before ordering. Households that can live with a 5.7 GPM flow rating and a replacement tank bill about every 2 years.

Who should skip this

Rhino owners hoping for a quiet PFAS benefit: it is not there, and no setting or add on cartridge changes that. Budget buyers: certified whole house PFAS treatment is the most expensive corner of this category, and a certified under sink reverse osmosis system covers drinking water for far less. Homes with no PFAS detection and no local contamination story: test first, because this is a problem specific purchase. Our water quality lookup and your utility's annual report are the place to start.

Bottom line

Does Aquasana remove PFAS? The HealthShield does, with a WQA certification to NSF/ANSI 53 for five compounds that you can verify in the certifier's listing. The Rhino does not, and its certifications cover chlorine and material safety only. Match the model to the problem: chlorine and taste across a decade points to the Rhino, certified PFAS reduction points to the HealthShield, and drinking water only protection points to a certified reverse osmosis unit.

Frequently asked questions

Does the Aquasana Rhino remove PFAS?

No. The Rhino is tested to NSF/ANSI 42 for chlorine reduction and carries no certification for PFAS. It was designed to strip chlorine out of city water across a 1,000,000 gallon tank life, and PFAS is simply not its job. If PFAS is your concern, the Rhino is the wrong Aquasana.

Which Aquasana whole house filter is certified for PFAS?

The HealthShield. It is WQA tested and certified to NSF/ANSI Standard 53 for five PFAS compounds, and to NSF/ANSI 53 for VOCs and NSF/ANSI 401 for BPA and ibuprofen as well. It is Aquasana's current flagship whole house system, and the one with the PFAS certification.

Which PFAS compounds is the HealthShield certified for?

Five: PFOA, PFOS, PFHxS, PFNA, and PFHpA. Aquasana states the system is certified to reduce up to 99.9 percent of those compounds to below 4 parts per trillion, at its rated flow, across its 165,000 gallon capacity.

Does Aquasana make a drinking water filter certified for PFAS?

Yes. The SmartFlow reverse osmosis system, an under sink unit for one tap, is tested and certified by WQA to NSF/ANSI Standards 42, 53, 58, and 401, and its Standard 53 certification covers PFOA and PFOS reduction. It treats drinking and cooking water only, not the whole house.

What level of PFAS does the EPA allow in drinking water?

The EPA set a legally enforceable limit of 4.0 parts per trillion for PFOA and for PFOS in public drinking water, with a health goal of zero for both. The agency kept those limits in place in its 2026 PFAS plan. Parts per trillion is a tiny scale: 4 parts per trillion is roughly four drops in twenty Olympic size swimming pools.

How long does the HealthShield last before it needs a new tank?

About 165,000 gallons, roughly 2 years for a typical household. A built in flow monitor tracks gallons used and shows remaining capacity, so there is no guessing. The replacement tank is the big ownership cost on this system, at about $1,749.
