Three-stage carbon filter with WQA-listed lead and PFOA/PFOS reduction
Source-based analysis, not hands-on testing. Our method
Cofounder of Superhuman Chambers · About the author.
The verdict
The Claryum 3-Stage Max Flow feeds its own faucet at a listed 0.72 GPM. WQA confirms named reduction claims for AQ-6300M with AQ-C3M-R, including lead, PFOA/PFOS, chlorine and chloramine. The catches are about $184 a year in filters and a one-year warranty.
The trade-off
Filters cost about $184 a year, and the warranty lasts one year unless you join Water for Life.

About this price
List price for the Chrome finish (model AQ-6300M-CHR) on the official product page. No sale or struck-through price showed on Oct 13, 2026. The page marked Chrome out of stock that day but still showed an Add to Cart button. It also shows a $359.99 Water for Life member price. The under-sink collection page listed the 3-Stage Max Flow at the same $449.99, with no sale. Before tax and shipping.
A GOOD FIT FOR
You're on city water and want lead and PFOA/PFOS reduction at a separate tap without reverse osmosis.
- City water where lead, PFOA/PFOS, chlorine or chloramine is your main worry
- You want filtered water at its own tap and want to keep the minerals
- You can handle basic DIY: a tee on the cold line and a few screws
- A sink with a spare sprayer or soap-dispenser hole, so you don't have to drill
THINK TWICE IF
- Well water with bacteria or virus concerns, unless you add UV disinfection
- You need arsenic, fluoride or nitrate reduction, which the data sheet doesn't list
- Hot-water lines or line pressure above 80 psi
- You want more than a one-year warranty without joining Water for Life
- You'd rather not change filters every six months
What still needs checking
- When Chrome will be back in stock
- Price of the replacement housing sumps
- Whether the faucet falls under the one-year warranty
- Whether an installed system can be returned within 90 days
- System weight
The practical details.
| Exact variant | AQ-6300M-CHR Chrome |
|---|---|
| Filter life | Aquasana recommends 800 gallons or about 6 months. WQA lists 800 gallons but says capacity and rated-service-cycle claims do not apply to mechanical filtration |
| Flow rate | 0.72 GPM in the WQA rows and Aquasana data sheet |
| Certification | Direct WQA listings: AQ-6300M with AQ-C3M-R under NSF/ANSI 42, 53 and 401; separate NSF/ANSI/CAN 372 lead-content compliance. Footnotes include AQ-6300M-CHR Chrome |
| Key test results | Lead 99.6% (pH 8.5); PFOA/PFOS 99.7%; chlorine 97.3%; chloramine 91%; cysts 99.995% |
| Stages | 5-micron pre-filter plus two Claryum filters |
| Operating limits | 20–80 psi; 40–90°F; cold water only |
| Faucet | Dedicated all-metal faucet; needs a hole at least 1/2 in wide |
| Dimensions | 4.25 L × 12 W × 12.85 H in, per Aquasana. Weight isn't listed. The manual asks for a mounting spot at least 12 in from the bottom of the cabinet so you can reach the filters. |
| Materials | A 5-micron pre-filter, then two Claryum filters that Aquasana says combine activated and catalytic carbon, ion exchange, sub-micron filtration and an "organic adsorbent booster". The faucet is all-metal, and Aquasana's FAQ says it's NSF tested and certified to contain no lead. |
Before you buy
InstallationAquasana says no plumber is needed
Aquasana says no plumber is needed. A brass tee goes on the cold-water supply line. The faucet goes through an existing hole at least 1/2 in wide, and a sprayer or soap-dispenser hole works. If you need a new hole, the manual strongly recommends a professional. The manifold screws to the cabinet wall. You'll need a drill, wrench, screwdriver, level and bucket. Flush for 10 minutes before drinking. It takes cold water only at 20 to 80 psi, so don't install it where line pressure may go above 80 psi.
WarrantyOne-year limited warranty from the date of purchase, for the original owner…
One-year limited warranty from the date of purchase, for the original owner, on systems bought from Aquasana or an authorized reseller. Filter cartridges are excluded, and the warranty says coverage may or may not include the faucet and fittings. Registration isn't required, but proof of purchase is. You pay labor, shipping and the return of defective parts. Water for Life members get an extended limited warranty for as long as the membership lasts.
Returns90 days from the order date, for purchases made directly from Aquasana
90 days from the order date, for purchases made directly from Aquasana. You need a return authorization code, and the return must arrive within 21 days of getting it. You have to send the whole system, since partial returns aren't accepted. You pay return shipping and insurance. The refund is the purchase price minus shipping and handling. The policy doesn't say whether an installed system qualifies.
More about this assessment
The Claryum 3-Stage Max Flow mounts under the sink and feeds its own faucet. WQA directly lists AQ-6300M with AQ-C3M-R under NSF/ANSI 42, 53 and 401. A listing footnote includes AQ-6300M-CHR Chrome. Named claims include lead, PFOA/PFOS, chlorine and chloramine reduction. Aquasana's data sheet supplies the percentage test results, not the WQA rows. Aquasana recommends new filters after 800 gallons or six months, at $91.99 a set. The $449.99 Chrome system was out of stock on October 13, 2026.
Strengths on paper
- Aquasana's data sheet gives a separate result for each tested contaminant
- Lead reduction is 99.6% to over 99.7% on the data sheet, depending on pH
- PFOA/PFOS reduction is 99.7% on the data sheet
- Chloramine is on the data sheet at 91%, which matters if your utility uses it
- 0.72 gpm, which Aquasana says is 44% faster than the regular Claryum 3-Stage
- Keeps calcium, magnesium and potassium in the water, per Aquasana
- An alarm sounds and a light turns red when the filters reach about 95% of capacity
- Filter changes don't need any hoses disconnected, per Aquasana
Limitations
- Filters cost $91.99 a set every six months, about $184 a year
- 800 gallons in six months is about 4.4 gallons a day, so a busy kitchen will need changes sooner
- The warranty lasts one year and may not cover the faucet
- Chrome was out of stock on the product page on Oct 13, 2026
- Used filters can't be recycled, per Aquasana's FAQ
- The "Recommended for Well Water" label comes with a note that UV must be added for bacteria and viruses

Recorded recurring parts and refills:
- Claryum 3-Stage Max Flow Filter Replacements (AQ-C3M-R): $91.99 every 6 months. One set holds two Claryum filters, a 5-micron pre-filter and a new alarm battery. It's rated for 800 gallons or 6 months, which works out to about 4.4 gallons a day. Heavier use means earlier changes. $91.99 is the regular price, and Water for Life members pay $78.19.
- Filter housing sumps: cost not recorded every 60 months. The manual says to replace the housing sumps every five years. Price not sourced.
- Purchase is the $449.99 list price on the product page on Oct 13, 2026, before tax and shipping. No sale price showed that day, and Water for Life members see $359.99.
- Installation is $0 if you fit it yourself. Aquasana says no plumber is needed and includes the faucet and tee. Drilling a new faucet hole, which the manual leaves to a professional, isn't priced.
- Filters are two $91.99 sets a year at the 6-month interval, or $183.98. Water for Life members pay $78.19 a set, or $156.38 a year.
- Energy is zero. The only power is a CR2450 coin battery for the change alarm, and a new one comes with each filter set.
- No subscription is required. Water for Life is optional, and Aquasana says you can cancel anytime.
- At list prices, three years comes to about $1,002. The housing sumps are due every five years, outside that window, and their price isn't sourced.
Evidence & sources.
Do water filters work? Our evidence review grades the research as Strong. That grade is about the claim, not about this product.
- CertificationWQA lists AQ-6300M with replacement AQ-C3M-R under NSF/ANSI 42 at 0.72 GPM and 800 gallons. Named claims are aesthetic chloramine, aesthetic chlorine, nominal particulate Class I, and taste and odor.9 Verified October 15, 2026. The row footnotes explicitly map AQ-6300M-CHR to Chrome. Capacity and rated-service-cycle claims do not apply to mechanical filtration. The listed system/component configuration is not a blanket standalone-cartridge certification.
- CertificationThe WQA NSF/ANSI 53 row lists AQ-6300M with AQ-C3M-R for asbestos, cyst, lead, mercury, MTBE, PFOS, PFOA, turbidity and VOC reduction as chloroform.10 The row lists 0.72 GPM and 800 gallons, with the mechanical-filtration capacity exception. It does not publish percentage reductions or establish reduction of every PFAS. Arsenic, fluoride, nitrate, TDS, bacteria and viruses are not named in the retrieved rows.
- CertificationThe WQA NSF/ANSI 401 row lists AQ-6300M with AQ-C3M-R for 15 named emerging compounds and microplastics. A separate NSF/ANSI/CAN 372 record lists AQ-6300M, including the Chrome finish footnote.1112 NSF/ANSI/CAN 372 concerns product lead content, not removal of lead from water. The 401 row carries the same mechanical-filtration capacity exception. Lead reduction is separately named under NSF/ANSI 53.
- Manufacturer claimAquasana's performance data sheet for the AQ-6300M says WQA tested and certified it to NSF/ANSI 42, 53 and 401. Under 42, it reports 97.3% chlorine and 91% chloramine reduction. Under 53, lead fell 99.6% at pH 8.5 and over 99.7% at pH 6.5. PFOA/PFOS fell 99.7%, and cysts fell 99.995%. Mercury fell 95.4% to over 96.2%. MTBE fell 85.5%, and the VOC surrogate fell 99.3%. Under 401, microplastics fell 99.6%. The 15 trace drugs and chemicals tested fell 92.3% to over 98.4%.3 Aquasana publishes these results from testing under standard lab conditions and says actual performance may vary. Dozens of VOCs are covered by a chloroform surrogate test rather than tested one by one. The sheet has no date or revision. It doesn't mention arsenic, fluoride, nitrate, TDS, bacteria or viruses.
- Manufacturer claimThe product and replacement-filter pages say Aquasana's filters are WQA tested and certified to NSF/ANSI 42, 53 (including P473) and 401.17911 The exact WQA listings were retrieved on October 15, 2026. They name NSF/ANSI 42, 53 and 401; the retrieved rows do not name P473. Keep the P473 wording attributed to Aquasana rather than treating it as an additional directly verified certification.
- CertificationThe NSF company-name query checked on October 13 returned whole-house UV listings, not an AQ-6300M or AQ-C3M-R name match.811 That scoped no-match does not establish certification status. Aquasana names WQA as the certifier, and the direct WQA rows now confirm AQ-6300M and its named claims.
- Manufacturer claimThe product page says the system removes up to 99.99% of 78 contaminants, including pesticides, herbicides and pharmaceuticals.1 This is a marketing summary. The data sheet gives a separate result for each contaminant, and they vary, so check the one you care about.
