Water Treatment
Average Cost: $90 - $3,000
Our Verdict: Aquasana is a good choice for homeowners who want NSF-certified filtration, whether you need a single shower filter or a whole-house Rhino system, and you can buy it without a dealer visit or in-home sales appointment. Prices are clear, you can find the products at major retailers, and the Water for Life auto-ship program helps lower long-term filter costs. But before you buy, keep in mind that the Rhino warranty does not transfer if you sell your home, using third-party replacement parts will void the coverage, and customer support can sometimes be slow to respond.
Aquasana is a U.S. water filtration brand known for its whole-house Rhino systems, under-sink Claryum drinking water filters, reverse osmosis options, and shower filters. You can buy their products online or at major retailers like Home Depot. There’s no need for a dealer consultation or an in-home sales appointment.
A.O. Smith acquired Aquasana in 2016, which helped the brand grow its distribution and manufacturing. Aquasana also has a Water for Life auto-ship program that makes filter replacement easier and cuts ongoing costs by 15%.
| Best for | Top model | Cost installed | Standout feature | Warranty |
|---|---|---|---|---|
| Whole-house filtration with long-life media | Rhino Whole House (EQ-1000 / WH-1000) | $1,000–$3,000+ | Long-life tanks rated up to 1,000,000 gallons | 10-year limited warranty on WH-1000 (non-transferable; see warranty section) |
Aquasana stands out because you can research, compare, and buy without needing an in-home sales appointment. This is a big plus for homeowners who want to avoid high-pressure sales tactics. The brand also offers NSF-certified filtration, clear pricing, and a 10-year warranty on its main Rhino system.
The Water for Life auto-ship program is another real advantage. Homeowners who sign up get a 15% discount on replacement filters and an extended warranty, which helps lower long-term costs if you keep up with regular maintenance.
There are some drawbacks, though. Customer support can be slow to respond, and if you use any replacement parts that aren’t from Aquasana, your warranty is void. This means you can’t buy cheaper compatible filters without losing coverage. Also, the Rhino warranty doesn’t transfer if you sell your home.

Aquasana’s lineup breaks into four product categories, each targeting a different scope of filtration need.
Cost (system only): ~$1,000–$1,500 depending on retailer and configuration
Aquasana’s main whole-house system uses tank media that lasts up to 1,000,000 gallons or 10 years, depending on the model. This is a much longer replacement interval than systems that need new media every year. It treats all the water in your home for chlorine, chloramines, and sediment. Installing it means cutting into your main water line, so it’s best to hire a licensed plumber, which adds $200–$600 to the total cost. Even with long-lasting tank media, you’ll still need to replace the pre-filters regularly.
Cost (system only): ~$3,000
The Max Flow bundle is made for bigger households and higher water use, like homes with several bathrooms or where lots of water is used at once. In most single-family homes with average water use, the standard Rhino is enough.
Cost (system only): ~$149 at retail
Aquasana’s under-sink drinking water filter uses Claryum technology and is NSF-certified to reduce chlorine, chloramines, lead, PFAS, and VOCs. It’s often rated highly in third-party tests for both contaminant reduction and flow rate. You’ll need cabinet space and a dedicated faucet hole to install it. Most people hire a plumber for installation, which adds $400–$600. Filters need to be replaced about every six months or after 800 gallons.
Cost (system only): $224.99 on Aquasana
This under-sink RO system is designed to be efficient and use less water than traditional RO systems. It also reduces fluoride and removes more dissolved solids than carbon-only under-sink filters. Installation and maintenance are more involved than with carbon-only systems. You’ll need to replace the pre-filters every 6–12 months and the RO membrane every two to three years.
Cost (system only): ~$89.99 on Aquasana
This shower filter has been independently tested to NSF/ANSI Standard 177 for chlorine reduction. It’s the easiest Aquasana product to install and takes just 10–20 minutes, with no plumbing experience needed. You’ll need to replace the cartridge every six months or after about 10,000 gallons.
Aquasana’s warranty terms are different for each product. There are a few important things to know before you buy, especially about labor costs, whether the warranty can be transferred, and the use of third-party parts.
Note: This is not a comprehensive list of all Aquasana products.
| Product | Housing/system warranty | Filter/cartridge warranty | Installation kit |
|---|---|---|---|
| Rhino WH-1000 whole-house | 10 years / 1,000,000 gallons | Not covered | 12 months |
| OptimH2O whole-house | 5 years (housing) | 1 year / 100,000 gallons (replacement filter only) | 12 months |
| Claryum under-sink | 12 months | Not covered | Not specified separately |
| Shower filter | 12 months | Not covered | Not specified separately |

Several exclusions apply consistently and are worth knowing before purchasing.
Aquasana will replace defective parts or units, but you have to pay for removal, reinstallation, shipping, and return shipping. For a whole-house Rhino system, where professional installation costs $200–$600, making a warranty claim means you’ll pay for plumber labor twice.
The warranty is explicitly voided “if moved from the original installation location.” The 10-year Rhino warranty ends when the house changes hands — it doesn’t pass to the new owner. If you’re buying the system partly as a home improvement that stays with the property, the warranty doesn’t support that framing.
Using any non-genuine Aquasana replacement filter, faucet, or diverter valve voids all coverage. This is a meaningful lock-in for a brand that positions itself as direct-to-consumer: shopping around for cheaper compatible filters isn’t warranty-safe. Always source replacements through Aquasana or an authorized reseller.
Replacement filter cartridges are excluded from warranty coverage across all products. Clogging caused by failure to replace the pre-filter also voids warranty coverage on the system itself.
If you purchase a whole-house bundle with a UV add-on, the UV component is explicitly excluded from the Rhino warranty and is covered under its own documentation.
Aquasana buyers frequently praise improved water taste, noticeable effects on skin and hair after installation, and the quality of the systems themselves. The consistent criticism across review platforms is customer support responsiveness — particularly when filters arrive damaged or replacements are needed urgently.
“The equipment is top-notch. The plumber said everything fit together like they were designed for each other.” — Darryl S., Google Reviews
“The filter was spendy for me to install but worth it so far. The taste of the water was immediately different and then I discovered that my hair and skin are really loving it. Things are easier to clean and my whites come out whiter. I would recommend this filter to anyone interested — it is a surprising and noticeable joy to have.” — Melody R., Home Depot
“After a few weeks my wife and girls noticed a difference in the way their hair and skin felt after showering.” — John T., Aquasana
“We have ours hooked up to a small under-sink water cooler and we love it. Have had it for three years now (AQ-RO3) and it really got all of us to drink more water — cold, refreshing, and healthy.” — Reddit Reviewer (three-year owner)
“Zero customer service. They sent a broken filter, ignored all my emails, and left my home without clean water for a week.” — Brittany S., Trustpilot
Brittany S.’s experience deserves attention. Getting a broken replacement filter and no email response for a week is a clear support failure, and it’s not the only complaint like this. If your filter arrives damaged or defective, contact Aquasana at 1-866-662-6885 and [email protected] at the same time, and have your order confirmation and product serial number ready. Because responses can be slow, it’s a good idea to keep a backup filter on hand while waiting for a replacement.
Aquasana systems cost anywhere from about $90 to over $3,000 for the system itself. Professional installation adds a significant amount to the total cost for whole-house systems. Because Aquasana sells directly to consumers, you pay separately for equipment and installation, with no dealer markup. This makes Aquasana competitively priced compared to dealer-sold systems with similar filtration performance.
| System type | Typical system price | Typical install add-on |
|---|---|---|
| Shower filter | ~$90–$170 | Usually DIY |
| Under-sink carbon filtration | ~$120–$250 | ~$550 average (varies by complexity) |
| Under-sink reverse osmosis | ~$225+ | Higher than basic under-sink installs |
| Whole-house filtration | ~$1,000–$3,000+ | ~$200–$600 labor, sometimes more |
Aquasana’s Water for Life program gives you a 15% discount on replacement filters through auto-ship, along with an extended warranty for systems that are enrolled. This helps lower long-term costs without needing a separate financing application. Before you sign up, check the auto-ship terms and how to cancel, since some reviews mention that managing the subscription can be tricky.
Aquasana’s main advantages over dealer-sold competitors are clear pricing and no need for an in-home sales appointment. Compared to other direct-purchase brands like Pelican and SpringWell, Aquasana offers a wider range of point-of-use products. While Brita focuses on improving taste and reducing chlorine, Aquasana also provides NSF-certified performance for lead, PFAS, and other confirmed contaminants.
Aquasana is in the middle of the filtration market. It’s more capable than pitcher brands, has clearer certification information than many entry-level filters, and is easier to access than dealer-only brands that require in-home consultations.
Culligan uses a dealer model, which means you need an in-home consultation, professional installation is included, and prices aren’t listed online. Installed costs for similar whole-house systems are usually $1,500–$3,000. Aquasana’s whole-house systems cost $1,000–$3,000 for the equipment, and you pay separately for installation. Aquasana’s clear pricing and direct purchase model are great for homeowners who want to research and compare before anyone comes to their home. Culligan’s main advantage is its all-in-one service, including equipment, installation, and ongoing support from one provider.
Pelican whole-house systems are also sold directly to consumers and cost about $300 to over $3,500, depending on your home’s size and setup. Both brands compete in the direct-to-consumer whole-house market. Pelican’s strength is its focus on whole-house systems and good prices for entry-level models. Aquasana’s advantage is a wider range of point-of-use products, like under-sink, RO, shower, and countertop options. This gives homeowners more flexibility to meet specific needs without having to buy a different brand for kitchen drinking water.

SpringWell is a direct-purchase whole-house filtration brand with clear pricing and detailed product information. Most of its whole-house systems cost around $1,500–$3,000. Both SpringWell and Aquasana are well-regarded in independent testing. SpringWell’s strength is its focused whole-house product line with detailed performance information. Aquasana’s advantage is its wide range of point-of-use products, which lets homeowners address both whole-home and specific drinking water needs with one brand.
Brita pitchers and faucet filters cost $20–$500 and are good for basic chlorine and taste improvement. They’re a good choice for renters or homeowners with mild water quality concerns who want something easy and affordable. Aquasana systems cost more but offer NSF-certified performance for a wider range of contaminants, including lead and PFAS. If you only care about taste and chlorine, Brita is enough. If you have other contaminants, especially lead or PFAS, Aquasana’s certified under-sink or RO systems can handle those issues, while Brita cannot.
Aquasana is a great option for homeowners who want trusted, NSF-certified filtration, whether you need just a shower filter or a system for the whole house. You can buy without dealing with high-pressure in-home sales. The direct-to-consumer model, clear pricing, and long Rhino system warranty make Aquasana one of the easiest choices in the water treatment market.
Keep three things in mind. First, the Rhino’s 10-year warranty doesn’t transfer if you sell your home and never covers labor. It’s a good warranty for the system itself, but it ends when you move out, and you’ll have to pay for any plumber costs if you need a warranty replacement. Second, using third-party filters voids your warranty, so include the cost of genuine Aquasana replacements in your budget. Third, customer support can be slow to respond. If a filter arrives damaged, follow up through several channels and keep a backup filter on hand.
Start by figuring out what problem you want to solve. If you need whole-home chlorine reduction, look at the Rhino. For specific drinking water contaminants, choose Claryum or SmartFlow RO. If you want quick improvements for skin and hair, try the shower filter. Buy the system that fits your needs, check the NSF certification for the contaminants you care about, use only genuine Aquasana replacement parts to keep your warranty, and consider the Water for Life program if you’re worried about ongoing filter costs.
