Quick Answer: Aquasana is a filter company that added scale control. Pelican is a scale-control company that sells filter add-ons. If your main complaint is chlorine taste and smell on city water, the Aquasana Rhino with salt-free descaler (EQ-1000-AST) is the better fit, rated at 1,000,000 gallons with a carbon and KDF filter. The bundled package isn't on Amazon right now, but you can build it from the Rhino EQ-1000 filter plus Aquasana's Rhino salt-free conditioner tank, which is listed for the EQ-1000. If your main complaint is scale in a bigger house, the Pelican NS6-P has twice the rated flow (15 gpm vs 7 gpm) and a lifetime warranty. Pelican's systems aren't currently sold on Amazon; the closest in-stock salt-free tank with the same 15 gpm rating is the Water Boss Whole House Salt-Free Scale Control. None of these soften water. For that, look at a salt-based softener with carbon, like the Fleck 5600SXT + upflow carbon.

A typical reader with this question lives on city water, can smell chlorine in the shower, and is tired of white crust on the faucets. They want one system that handles both, without salt bags or a drain line. Both Pelican and Aquasana sell exactly that, but they come at it from opposite ends, and that shows in the specs.

Start with which problem bothers you more
If it's the taste and smell: Aquasana's core product is the Rhino whole-house filter. Aquasana lists a sediment pre-filter, a copper-zinc (KDF) stage, an activated carbon stage and a post-filter. It says the system reduces up to 97% of chlorine, independently tested to NSF/ANSI 42. The salt-free conditioner is a separate tank Aquasana sells as an add-on, and it's included in the EQ-1000-AST package.
If it's the scale: Pelican's core product is the NaturSoft salt-free conditioner. Its manual cites DVGW testing (DW-9191) at 99.6% scale prevention. Pelican sells carbon filtration and UV as combo packages around it.
If it's both, equally: keep reading, because flow and maintenance will decide it.
Flow: this is the real gap
| Aquasana Rhino + salt-free | Pelican NaturSoft | |
|---|---|---|
| Rated flow | Filter: 7.0 gpm (14.6 peak); conditioner: 7.0 gpm (15.3 peak) | NS3: 10 gpm max; NS6: 15 gpm max |
| Sized for | Aquasana says most homes use 2–3 gpm | NS3: 1–3 baths; NS6: 4–6 baths (per Amazon listings) |
| Pipe size | 3/4" or 1" main | Not specified in the manual |
| Pressure / temp limits | Up to 100 psi; 40–90°F | 25–80 psi; 36–120°F |
| Pre-filter | 20" sediment, every 2 months (low-maintenance version: every 6 months) | 5-micron poly-spun, every 6–9 months |
| Rated life | Filter and conditioner: 1,000,000 gal or 10 years each | No capacity stated |
| Warranty | 10-year limited; 90-day satisfaction guarantee | Limited lifetime (registered owner; labor not covered) |
Aquasana's 7 gpm rating is fine for a 2-bath home where two fixtures rarely run at once. Aquasana itself notes that typical use is 2 to 3 gpm. In a 4-bath house with a big family in the morning, 7 gpm rated is tight, even with the higher peak figure. Pelican's NS6 is rated at 15 gpm, which is a better match for a large home. Aquasana also sells a Rhino Max Flow version rated at 14 gpm if you want the filter-first approach in a bigger house.
What's actually in each tank
Aquasana EQ-1000-AST: Its retail listing described it as a salt-free descaler with carbon and KDF media that filters sediment and 97% of chlorine, rated to 1,000,000 gallons. Aquasana's own site says the filter tank is WQA certified to NSF/ANSI/CAN 61, which is a material-safety standard. It doesn't list a certification for the salt-free conditioner, and it doesn't publish a scale-reduction percentage for it.
Pelican NaturSoft: The manual describes catalytic NaturSoft media with a 5-micron sediment pre-filter. It lists WQA Gold Seal certification to NSF/ANSI 61 and 42, but the manual is careful to say that covers material safety and structural integrity only. The performance claim rests on the DVGW scale test.
The combo packages: Pelican's filter-plus-conditioner packages, like the PSE2000-PUV-14-P for 4–6 bathrooms, also include a UV stage, and they aren't currently in stock on Amazon. Aquasana sells the same idea as one system: the Aquasana WH-1000-CS-UVS-B combines pre- and post-filters, carbon, KDF, salt-free Scale Control Media and a UV stage certified to NSF/ANSI 55 Class B, rated for 1,000,000 gallons or 10 years. UV is for bacteria, which matters on a private well and much less on treated city water. If you're on city water, you may be paying for a stage you don't need.
Both conditioners work the same basic way, by changing how hardness minerals behave rather than removing them. See how a salt-free conditioner works. Neither will dissolve scale that's already in your water heater. Our guide on salt-free conditioners and existing scale explains why you should flush the heater when you install one.
Year-one upkeep, honestly
This is where the two feel most different to live with.
Aquasana's standard 20-inch pre-filter is a two-month change, so six cartridges a year. The low-maintenance pre-filter stretches that to every six months. If you're not someone who remembers filter changes, buy that version. Pelican's pre-filter is every 6 to 9 months, so one or two changes a year.
The long-term parts are the reverse. Aquasana tells you exactly when to replace the big tanks: 1,000,000 gallons or 10 years. Pelican's manual doesn't give a capacity, so you can't plan a replacement date from the documents.
What does 1,000,000 gallons mean in years? Use the same 75 gallons per person per day we use for softener sizing. A family of four runs about 300 gallons a day, or roughly 110,000 a year. That's about nine years, so the gallon limit and Aquasana's 10-year limit arrive at about the same time. A family of six at 450 gallons a day gets through it in about six years. Plan your replacement on whichever comes first, not on the "10 years" printed on the box.
Don't skip the pre-filter on either one. A clogged sediment cartridge is the first thing that drops household pressure, and both brands treat neglected filters as a warranty issue. Our page on sediment pre-filters explains why that cheap cartridge protects everything downstream.
Install and placement
The Rhino ships with a Schedule 80 PVC assembly kit, a drain valve, a shut-off valve, tank connections and the pre- and post-filter housings. It fits 3/4- or 1-inch main lines. Aquasana lists an operating range of 40–90°F and up to 100 psi. That 90°F ceiling is worth noting if you planned to mount it in a hot garage or an outdoor utility closet in the Southwest. Put it somewhere shaded or inside.
Pelican's NaturSoft manual lists 25–80 psi and 36–120°F. On a well, it says to install after the pressure tank or booster pump. If your city pressure runs above 80 psi, add a pressure-reducing valve before the Pelican.
On a private well? Aquasana's page says a UV stage is needed for bacteria and viruses. Aquasana sells a Rhino Well version with UV, rated at 500,000 gallons or up to 5 years. Pelican's combos already include UV, as does Aquasana's WH-1000-CS-UVS-B system. Either way, test for iron and manganese first. A salt-free conditioner isn't an iron filter, and iron reaching the media is the quickest way to ruin it.
Warranty and returns
Pelican offers a limited lifetime warranty on tanks (13" and smaller), valves, heads, bypasses, fittings, media and housings, for the original registered owner, with registration due within 90 days. Labor isn't covered.
Aquasana lists a 10-year limited warranty and a 90-day satisfaction guarantee on the Rhino. That guarantee is a real advantage if you're unsure whether you'll like the results.
If you need something neither one does
- Chlorine is the only problem, no scale worries: skip the conditioner and buy the Aquasana Rhino EQ-1000 filter alone. Check price on Amazon.
- You want genuinely soft water plus chlorine removal: a salt-free tank won't stop spots or make soap lather better. A softener with a carbon tank will. The AFW Fleck 5600SXT 48k with upflow carbon pairs a 48,000-grain softener with a carbon filter and 10% crosslink resin. Our guide to running carbon and a softener together explains the order. Check price on Amazon.
Which house each one suits
- Aquasana EQ-1000 + salt-free conditioner (the EQ-1000-AST setup): 1–3 bathrooms, chlorine taste is the top complaint, and you want a defined 10-year replacement schedule. Aquasana says the conditioner tank works best below 15 gpg hardness, 250 mg/L alkalinity, pH 8.3 and 0.3 ppm iron. Check price on the filter and the conditioner tank.
- Pelican NS6-P: 4–6 bathrooms, scale is the top complaint, and you want the higher flow rating and lifetime coverage. Add your own carbon filter if needed. It's not on Amazon right now. The in-stock alternative, the Water Boss Salt-Free Scale Control, is rated up to 15 gpm, sized for households of four or more, and lasts 600,000 gallons. It has the same 15 gpg / 0.3 ppm iron limits as Aquasana's tank and doesn't reduce TDS, sulfur or iron. Check price on Amazon.
- Aquasana filter + salt-free + UV system: you're on a well that has already been treated for iron and you want carbon, scale control and UV from one vendor. Check price on Amazon.
