Cofounder of Superhuman Chambers · About the author.
The Standard Rhino is a no-power, no-drain whole-house tank of copper-zinc (KDF) and activated carbon, rated for 1,000,000 gallons or 10 years and a 7.0 GPM flow. Aquasana's only published performance data is for free chlorine: more than 97.4% overall in NSF/ANSI 42 testing, slipping to about 92% to 93% near the end of the rated 1,000,000 gallons. It isn't certified for contaminant reduction, so it suits chlorinated city water but not chloramine-treated water, well water with microbial concerns, or a need for certified lead or PFAS reduction.
Aquasana publishes test data only for free chlorine, the pre-filter needs changing every two months, and the recommended plumber and extra valves aren't priced.

THINK TWICE IF
| Exact variant | Standard Rhino (model WH-1000), 1,000,000 gallons or 10 years, no add-ons |
|---|---|
| Rated capacity | 1,000,000 gallons or 10 years |
| Flow rate | 7.0 GPM rated flow; 14.6 GPM peak in the product page's size chart |
| Home size | Up to 2.5 bathrooms and 4 or fewer people |
| Filtration stages | 20 in pre-filter, then an upright tank (copper-zinc KDF media in the top section, activated carbon in the bottom), then a 10 in post-filter |
| Published test result | Free available chlorine: Aquasana reports more than 97.4% overall reduction from a 2.02 mg/L (±10%) challenge, against a 50% minimum, in NSF/ANSI 42 testing run to 1,000,000 gallons. Chlorine in the filtered water was non-detect through about half of rated capacity and 0.15 mg/L (91.94% and 92.82% reduction) in the last two samples. The test flow rate isn't stated. The data sheet says it's not certified for contaminant reductions by WQA |
| Pressure drop | 23 psi in the NSF/ANSI 42 chlorine test, at 60 psi dynamic pressure. The data sheet doesn't give the flow rate |
| Operating limits | 20 to 100 psi; 40 to 90°F; cold-water line only |
| Connections | Fits 3/4 in or 1 in main lines. The 1 in PVC shut-off valve comes with reducer bushings for a 3/4 in line |
| Power and drain | None: no electricity, drain line or backflushing |
| Dimensions | The base unit is 46 in tall with a 9 in diameter, according to the product page's size chart. The chart's length entry says "Please see chart below" instead of giving a number. The owner's manual says to allow at least 50 in of height clearance for the tank and at least 44 in of floor space. Aquasana doesn't state the weight or the assembled footprint. |
| Materials | The tank is molded from food-grade HDTE (high density, tri-extruded) material. Aquasana says it's WQA certified to NSF/ANSI/CAN 61, for materials safety only. The data sheet adds CSA B483.1 for materials safety and structural integrity. The media is copper-zinc (KDF) in the top section and activated carbon in the bottom section. Aquasana doesn't say what form the carbon takes. The assembly kit uses Schedule 80 PVC components, a 1 in PVC shut-off valve and a 1/2 in brass drain valve. |
It goes where the main water line enters the home, before the water heater, on cold-water lines only. It fits 3/4 in or 1 in main lines. Aquasana strongly recommends a licensed plumber. The manual says some local codes may require one and that installation could take 1 to 4 hours. Where pressure is high (for example above 60 psi), the manual recommends a pressure-reducing valve or regulator. It also recommends water hammer arrestors at the beginning and end of the system. It strongly recommends a check valve at the end of the system, before the water heater. On metallic plumbing, it says two grounding clamps and #4 copper wire are essential. Neither is in the kit's parts list. The manual recommends an indoor spot out of direct sunlight. Outdoors, the unit must be protected from sunlight and freezing. The tank must stand upright and be flushed before water enters the house. No electricity, drain line or backflushing is needed. The manual lists the Pro-Grade Bypass Kit (for 1 in PEX connections) among recommended tools, but it's a separate add-on and isn't included with the base unit.
The Rhino WH-1000 system has a limited warranty of 10 years or 1,000,000 gallons against defects in materials or workmanship. The installation kit bought with the system and the pre- and post-filter housings get 12 months. Coverage applies only if the system is installed, operated and maintained according to the instructions. Filter cartridges aren't covered. Neither is damage from non-genuine parts, a filter moved from its original installation location, clogging from not replacing the pre-filter, iron or sediment build-up, misuse, freezing, direct sunlight, over-pressurization, or fire and flood. The warranty applies only to products bought from authorized Aquasana resellers. The document also notes that water conditions and use rates may limit the filter's functional lifespan. You need proof of purchase, but you don't need to register. The remedy is replacement of the defective part, or a replacement that covers the remaining estimated life. You pay labor plus all freight, shipping and handling, including returning the defective unit.
Aquasana's 90-Day Satisfaction Guarantee covers products bought directly from Aquasana. Returns are accepted within 90 calendar days of the order date, with prior authorization and a Return Authorization Code. The return must reach Aquasana within 21 calendar days of the code being issued. Filtration systems go back as complete units, and partial returns aren't accepted. You pay return shipping and insurance. The refund is the purchase price, excluding shipping and handling. It goes to the original payment method within 15 business days of receipt. The policy mentions no restocking fee and doesn't say whether an installed system can be returned.
The Standard Rhino is Aquasana's whole-house tank filter for up to 2.5 bathrooms and 4 or fewer people. It's rated for 1,000,000 gallons or 10 years and needs no electricity, drain line or backflushing. Aquasana says it was independently tested to NSF/ANSI 42 for free chlorine, the only contaminant with published data. It isn't certified for contaminant reductions by WQA. It's $999 on sale, and filters cost about $148 a year at regular prices. Aquasana strongly recommends a licensed plumber, and that cost isn't included.
