SpringWell vs Aquasana

We earn a commission if you buy through links on this page. It never changes which systems we recommend. Details.

Short answerFor city water, the SpringWell CF1 beats the Aquasana Rhino on flow, warranty and 10-year cost (about $2,013 vs $3,428). For wells with iron or sulfur, the SpringWell WS1 wins; for certified PFAS reduction at every tap, only Aquasana HealthShield qualifies, at about $12,324 over 10 years.

The SpringWell CF1 is a better whole-house filter than the Aquasana Rhino for most homes on city water. It flows 9 gpm to the Rhino’s 7, carries a lifetime tank warranty instead of a prorated 10-year one, and costs about $1,415 less over 10 years.

Aquasana wins in two places. Its 90-day guarantee refunds the product price with no restocking fee, and its HealthShield is the only system from either brand certified to reduce five PFAS at every tap.

Well & Tap did not install or lab test these systems. Everything below comes from maker spec sheets, performance data sheets and the NSF, IAPMO and WQA listings, with prices checked September 2026. See how we research.

Which one wins for you

• City water with chlorine: SpringWell CF1. More flow, a lower 10-year cost, and no drain or power needed.
• City water with chloramine: SpringWell CF1, narrowly. Aquasana’s Rhino Chloramines publishes real test data, but it costs $1,399 up front and about $4,178 over 10 years.
• Lowest upfront price in a smaller home: Aquasana Rhino WH-1000 at $999, if you accept higher running costs.
• Well water with iron, manganese or a sulfur smell: SpringWell WS1. The Rhino Well Water with UV treats none of the three.
• Certified PFAS reduction at every tap: Aquasana HealthShield. For drinking water alone, a certified under-sink or countertop RO costs a fraction as much.

Differences that matter

Certification: mostly claims on both sides

SpringWell has no system listed at NSF, IAPMO or WQA. The CF1 page says it removes “PFAS, PFOA and PFOS” but cites no standard, certifier or test report.

Aquasana is careful in its data sheets and loose on its product pages. The Rhino data sheet says “Not certified for contaminant reductions by WQA” and lists only chlorine (97.4% reduction, tested to NSF/ANSI 42). The Rhino pages still show a “78 contaminants” list, PFOA and PFOS included, borrowed from Aquasana’s Claryum drinking-water filters.

Flow and home size

The CF1 is rated 9 gpm for 1 to 3 bathrooms. The Rhino WH-1000 is rated 7 gpm for up to 2.5 bathrooms and 4 people.

For bigger homes, SpringWell’s CF4 (12 gpm, $1,294.13) undercuts the Rhino Max Flow (14 gpm, $1,399), whose replacement tank alone is $1,299. HealthShield’s 5.7 gpm is the lowest here, so check your peak demand in the sizing guide first.

Chloramine

The CF1 uses catalytic carbon and KDF. SpringWell’s warranty page adds a performance guarantee that the carbon keeps chlorine and chloramine below detection for 6 years or 1 million gallons, but SpringWell publishes no reduction data behind it.

Aquasana sells chloramine as a separate model. The Rhino Chloramines data sheet reports 83% average reduction, and its own table shows that falling to 68.7-75.5% over the last 400,000 of its 1,000,000 gallons. If your utility uses chloramine, read chloramine vs chlorine.

Running costs and the permanent sale

The Rhino’s 20-inch pre-filter is changed every 2 months and its post-filter every 6, which adds $147.96 a year. Its replacement tank is $949, nearly the price of the whole $999 system.

The CF1 needs a sediment cartridge every 6-9 months (a 10-inch 2-pack is $42.19) and new media ($351.70) at the end of its life. Before install, the manual says the carbon must soak for 48 hours and be flushed.

Aquasana’s “50% off” banner never moves: the MSRP on every system and tank checked was exactly twice the sale price, so treat $999 as the real price. SpringWell’s 15% sitewide discount is already in the prices here.

Warranty and returns

SpringWell covers tanks, valves, housings and heads for life, for the registered original owner at the original address. The Rhino’s 10-year warranty is prorated, covers housings for 12 months, is void if you move, and excludes failures from iron or sediment build-up.

Returns favor Aquasana. Its 90-day guarantee refunds the product price on direct orders (you pay return shipping; install labor is not covered). SpringWell’s “6-month money-back guarantee” applies only to unused, uninstalled systems, with a 10% restocking fee and return shipping on you.

Owner feedback is thin or poor for both. Aquasana’s Trustpilot page shows 1.5 from 172 reviews; SpringWell’s shows 2.9 from just 2.

Well water: the two systems do different jobs

The WS1 injects air to oxidize iron, manganese and hydrogen sulfide, traps them in Greensand Fusion media and backwashes nightly. It needs a drain and an outlet, and SpringWell holds orders until a $134.25 water test (non-refundable) confirms your water fits. It does not disinfect.

The Rhino Well Water with UV is a carbon and KDF tank with a UV lamp. It removes no iron, manganese or hardness, yet Aquasana says the UV needs iron under 0.3 ppm, manganese under 0.05 ppm and hardness under 7 gpg to work. Its UV unit holds NSF/ANSI 55 Class B, which covers supplemental treatment of water already considered safe, not disinfection of contaminated water.

If your well tests positive for coliform, neither system is the answer on its own; look for a UV certified to NSF/ANSI 55 Class A. Start with how to test well water.

PFAS: where HealthShield fits

HealthShield is WQA-certified to NSF/ANSI 53 for PFOA, PFOS, PFNA, PFHxS and PFHpA plus VOCs, and to NSF/ANSI 401 for BPA and ibuprofen. Neither the CF1 nor any Rhino has a comparable certification. Its chlorine and chloramine figures are internal tests only; the data sheet says WQA did not evaluate them.

The catch is the tank: 165,000 gallons or about 2 years, then $1,749. At EPA’s WaterSense figure of 300 gallons a day for an average family, all of it through the tank, that is about 18 months.

SpringWell’s closest answer is its Lead & Cyst Removal System ($1,554), a rebadged Enpress Pioneer that IAPMO certifies to NSF/ANSI 53 for PFOA and PFOS, under Enpress’s name, at 4.51 gpm. SpringWell advertises it at 8 gpm. Its PFS-1 PFAS filter ($2,910.40) claims non-detect results, but the matching OEM sheet says its claims are “not performance tested by WQA, IAPMO or NSF”.

You may not need whole-house PFAS treatment at all. EPA says showering, bathing and washing dishes in water containing PFAS “are unlikely to significantly increase your risk.” Compare the cheaper route in whole house filter vs reverse osmosis and check your utility in the PFAS lookup.

Price over 10 years

Method: purchase price, plus 10 years of scheduled filters, plus one replacement of the main media or tank, at September 2026 prices. Installation, electricity and water are not included.

The CF1 row assumes one sediment 2-pack a year. If its media lasts 6 years, as the 2020 manual says, you still buy it only once in the decade. SpringWell lists no replacement media price for the WS1.

Who should buy which

Best for city water: SpringWell CF1

Buy the CF1 if you are on chlorinated or chloraminated city water and want the lowest 10-year cost with no drain or power. Do not buy it expecting certified PFAS removal. Details are in the CF1 review.

Lowest upfront price: Aquasana Rhino

The Rhino makes sense if $999 is your ceiling, you have 2.5 bathrooms or fewer, and you want a 90-day refund window. Over a decade you will spend more on filters and the tank than on the system. More in the Rhino review.

Best for iron and sulfur: SpringWell WS1

The WS1 is the pick for rust stains or a rotten-egg smell within its 7 ppm iron and 8 ppm sulfide limits. Add a Class A UV if bacteria show up in your test.

Certified PFAS at every tap: Aquasana HealthShield

Choose HealthShield only if your results show PFAS and you want certified reduction at every tap, not just the kitchen. Budget $1,749 for a tank about every 2 years. See the HealthShield review.
