Quick Answer: “Pentair water filter” in 2026 really means three different things, and knowing which one you want saves you real money. The Pelican-heritage systems everyone still searches for — PC600, PC1000, NaturSoft — are discontinued for new sales: Pentair bought Pelican Water Systems in a $120 million deal (per WaterWorld), retired the brand in January 2022, closed the in-home sales division, and now routes whole-house buyers to a dealer-quote channel with no published prices. What you can still buy, today and on Amazon, is Pentair’s component ecosystem — Pentek cartridges, OMNIFilter housings, and the FreshPoint reverse osmosis line — plus clearance stock of the old systems (FactoryPure listed the PC600 at $1,049, out of stock, in July 2026). If you just want a new whole-house filter with a listed price, the SpringWell CF1 (~$1,016+) and the iSpring WGB32B ($516.99 on iSpring’s own site) are the in-production alternatives to shortlist.

This page is the decoder Pentair doesn’t publish: what happened to the brand, the honest 2026 status of every Pelican-heritage model, the parts that keep an existing system running, and what to buy instead if you’re starting from scratch.

What happened to Pelican Water Systems

The timeline matters because it explains everything odd about shopping for Pentair today:

January 2019 — Pentair announces a definitive agreement to acquire Pelican Water Systems, then one of the biggest direct-to-consumer names in whole-house filtration. WaterWorld reported the deal at $120 million in cash; Pentair’s investor-relations releases confirm the acquisition closed in December 2019.
January 2022 — Pentair announces the Pelican brand has “evolved into Pentair Water Solutions,” with PelicanWater.com folded into Pentair.com (BusinessWire, January 25, 2022). The same year, the Pentair Pelican in-home sales division was closed, per Pentair’s own support documentation as cited by water-industry retailers.
2026 — pentair.com’s home water treatment section has no cart and no prices. Every category — water softening, whole-home filtration, iron filters — ends in a “Contact a Local Pro” dealer locator. The PC600 and PC1000 product pages are still live with full specs, which is exactly why so many shoppers assume the systems are still on sale. They aren’t; they’re reference pages for a discontinued line.

The practical upshot: Pelican was a published-price, buy-it-online brand, and Pentair converted it into a pro-installer channel. If you liked the Pelican model of shopping — see the price, order the tank, install it yourself or hire a plumber — that model now lives at competitors like SpringWell and iSpring, not at Pentair.

Every Pelican-heritage model, decoded for 2026

Legacy model	What it is	Official spec	2026 status	Last seen street price
PC600 (PC600-P)	Whole-house carbon, 1–3 baths	650,885 gal or 5 yr media, 10 GPM, NSF/ANSI 42 + 61 (IAPMO), 97% chlorine reduction	Discontinued; page live on pentair.com, no price	$1,049 (FactoryPure, out of stock)
PC1000 (PC1000-P)	Whole-house carbon, 4–6 baths	1,301,770 gal or 5 yr media, 15 GPM	Discontinued	$1,149, down from $2,099 list (FactoryPure, out of stock)
NaturSoft NS3	Salt-free scale conditioner, 1–3 baths	TAC media, up to 10 GPM, NSF/ANSI 42 + 61	Discontinued; scattered dealer stock	~$1,699 (Healthier Elements, in stock)
NaturSoft NS6	Salt-free scale conditioner, 4–6 baths	15 GPM, max 75 gpg, DVGW-certified 99.6% scale prevention, 5-yr warranty	Discontinued	$1,629 (FactoryPure, out of stock)
WF4 / WF8 Iron & Manganese	4-stage well-water combo	Up to 10 PPM combined iron + manganese removal	Page live, dealer-quoted only	~$3,600 (WaterFilterGuru, 2026)
FreshPoint GRO-350B	3-stage under-sink RO	50 GPD, NSF/ANSI 42 + 58 certified	Still sold via parts dealers	~$348 (watersoftener-parts.com)

Two spec details in that table are worth calling out, because they’re the numbers marketing rounds off. The PC600’s real rated capacity is 650,885 gallons — not “600,000” — and the PC1000’s is 1,301,770 gallons, both straight from pentair.com’s product pages. And the NaturSoft’s famous scale claim is a DVGW certification for 99.6% scale prevention — the German standard that actually bench-tests scale performance — on top of IAPMO certification to NSF/ANSI 42 and 61. What none of the whole-house line carries is NSF/ANSI 53 or 401 certification, so treat any lead/PFAS removal claims for these tanks as uncertified.

What Pentair actually sells in 2026 (that you can buy today)

Here’s the part most “Pentair review” pages miss: the searchable, buyable Pentair ecosystem didn’t die with Pelican — it moved down a level, to cartridges and housings. Pentair owns Pentek, the cartridge brand that descends from the old Ametek filter business, and OMNIFilter, and both are widely stocked on Amazon.

Pentek DGD-5005 — the workhorse sediment cartridge

Pentek DGD-5005 Dual-Gradient Sediment Cartridge (10" Big Blue)

Best-known Pentair SKU · 5-micron dual-gradient depth filter · fits standard 10" Big Blue housings

Dual-gradient polypropylene depth design: the outer layer catches coarse sediment, the inner layer polishes down to 5 microns — so it loads up slower than a single-density cartridge and lasts longer between changes.
Fits any standard 10" Big Blue housing (Pentair's own, OMNIFilter, iSpring, whatever you have), which is exactly why it's the default recommendation in our sediment filter guide.
Also available as the DGD-2501 (25/1 micron) and in 20" Big Blue sizes (DGD-5005-20) for higher-flow homes.

Cartridge systems live or die on whether you actually change the cartridges, and a whole-house sediment cartridge is a 6-to-12-month consumable. That’s the honest trade against the old PC600 tank design — the tank asked for attention once every five years; a Big Blue setup asks twice a year, in exchange for costing a fraction as much upfront.

Pentek RFC-BB and carbon cartridges — chlorine, taste and odor

Pentek RFC-BB Radial-Flow Carbon (10" Big Blue)

Whole-house carbon in cartridge form · granular activated carbon, 25 micron · pairs behind a DGD sediment stage

Radial-flow GAC design keeps pressure drop low at whole-house flow rates — the usual complaint with carbon-block cartridges — while cutting chlorine taste and odor.
Pair one behind a DGD-5005 in a two-housing setup and you've rebuilt the basic logic of a PC600 (sediment stage → carbon stage) for a few hundred dollars in hardware.
Prefer a tighter carbon block for a low-flow branch line? The Pentek EP-20BB is the standard pick; the P5 spun-poly handles point-of-use sediment.

OMNIFilter housings and systems — the chassis

Pentair OMNIFilter Big Blue Housings & Whole-House Systems

Pentair's retail housing brand · 10" and 20" Big Blue formats · the cheap way into whole-house filtration

OMNIFilter is Pentair's stocked-on-Amazon housing and starter-system brand — the BF7 10" Big Blue system, BF55 20" housing, and standard-size U30/OB1 units all take industry-standard cartridges.
Standard-format housings mean you're never locked to one brand's consumables — Pentek, iSpring and generic cartridges all fit, which is the single best argument for building rather than buying a proprietary tank.
Add a ball-valve bypass and mount it where the main line enters the house; our whole-house guide covers sizing.

FreshPoint GRO-350B — the certified RO survivor

Pentair FreshPoint GRO-350B 3-Stage Reverse Osmosis

Under-sink RO · 50 GPD · NSF/ANSI 42 + 58 certified · ~$348 at parts dealers

The quiet survivor of the consumer line: tested and certified by NSF International to NSF/ANSI 42 and 58 (plus CSA B483.1), with a high-efficiency GRO membrane that wastes less water than a standard 4:1 membrane.
Reduces chlorine, fluoride and lead at the tap; the F1GC-RC replacement cartridge sold at Home Depot is marketed as NSF-certified for PFOA/PFOS reduction.
At ~$348 it competes on price with Waterdrop and iSpring under-sink units — compare certifications in our under-sink guide before choosing.

If you already own a Pelican system

Good news first: your system is not orphaned. Pentair committed to supporting legacy Pelican owners, and the consumables pipeline is intact:

PC600 owners: replacement carbon media is the PC600-R, about $242.50 at Home Depot, on a 5-year / 650,885-gallon cycle. PC1000 owners use the PC1000-R on a 5-year / 1,301,770-gallon cycle.
Everyone: the sediment pre-filter (PC40-P family) needs changing every 6 to 9 months — around $22 per cartridge, and skipping it is the number-one way owners kill their flow rate.
Support: Pentair runs a dedicated legacy line at 877-842-1635 ([email protected]) for Pelican-heritage systems.

The 5-year warranty on the systems (or the gallon cap, whichever comes first) still applies to units bought before discontinuation; the NS6 carried a 5-year limited warranty as well. Keep your purchase receipt — dealer stock sold in 2026 still starts that clock at purchase.

Buying new in 2026: the published-price alternatives

If you came here to buy a new whole-house system rather than to service an old one, the honest comparison looks like this:

System	Status	Price	Media life	Warranty
Pentair PC600	Discontinued, clearance only	$1,049 last seen (out of stock)	650,885 gal / 5 yr	5 yr or gallon cap
SpringWell CF1	In production	~$1,016+ (2026 reviews cite up to $1,144)	1,000,000 gal / ~10 yr	Lifetime tanks & valves
Aquasana Rhino EQ-1000	In production	~$1,600 retail	1,000,000 gal / 10 yr	10 yr (pro install required)
iSpring WGB32B	In production	$516.99 (ispringfilter.com)	100,000 gal cartridges	1 yr (extendable)
DIY: 2× Big Blue + Pentek	Always available	~$200–350 in parts	6–12 mo cartridges	Per component

Read that table and the strategy writes itself. Chasing clearance stock of a discontinued Pentair tank only makes sense at a steep discount, because you give up warranty runway and buy into a shrinking parts channel. At the same money, the SpringWell CF1 gets you an in-production system with double the media life and a lifetime structural warranty. On a budget, the iSpring WGB32B at $516.99 — or a self-built OMNIFilter/Pentek Big Blue chain for even less — covers sediment and chlorine for half the price. And if scale is your actual problem, compare the NaturSoft’s remaining dealer stock against the in-production salt-free conditioners before paying legacy-brand prices, or test first with a proper water test kit to confirm hardness is the issue at all.

Bottom line

Pentair didn’t leave residential water treatment — it left retail. The brand you’re probably searching for (Pelican’s published-price tanks) is discontinued; the dealer channel that replaced it won’t show you a number without a house call; and the parts of Pentair you can still buy off the shelf — Pentek cartridges, OMNIFilter housings, the FreshPoint RO — are genuinely good, standards-based hardware that this site recommends constantly in other guides. Service what you own, build with the components, and buy your next tank from a brand that still prints its prices.

Frequently Asked Questions

Is Pelican Water Systems still in business?

Not as a consumer brand. Pentair announced its acquisition of Pelican Water Systems in January 2019 — a $120 million cash deal per WaterWorld — and completed it in December 2019. In January 2022 Pentair announced the Pelican brand had 'evolved into Pentair Water Solutions,' folding it entirely into Pentair.com, and the Pentair Pelican in-home sales division was closed the same year. Pentair still supports existing Pelican owners with replacement media and a dedicated support line, but you can no longer buy a new system the way Pelican customers once did — direct from the company with a listed price.

What happened to the Pentair Pelican PC600 and PC1000?

They are discontinued for new sales. The product pages technically remain on pentair.com — with full specs but no price and no cart — and remaining retail stock is drying up: FactoryPure listed the PC600 at $1,049 and the PC1000 at $1,149 (down from a $2,099 list) in July 2026, both out of stock. If you find new-old stock at or below those numbers it's a legitimate buy — the hardware was always solid — but plan around the consumable: replacement carbon media (PC600-R, about $242.50 at Home Depot) is what keeps the system alive, and it stays available because Pentair committed to supporting legacy owners.

Are Pentair whole-house filters NSF certified?

Yes, but read the standard numbers carefully. The PC600 and PC1000 are certified by IAPMO R&T to NSF/ANSI 42 — chlorine taste and odor reduction plus structural integrity — and NSF/ANSI 61 for material safety, and Pentair rates the system to reduce 97% of chlorine. What they are not certified to is NSF/ANSI 53 (health claims like lead or cyst reduction) or NSF/ANSI 401 (emerging contaminants). That's normal for big-tank carbon systems — SpringWell's CF line isn't 53-certified either — but if a seller implies the PC600 is certified to remove lead or PFAS, that claim has no certification behind it.

Does Pentair still sell the NaturSoft salt-free water softener alternative?

Not to consumers through its own site. The NaturSoft NS3 and NS6 are part of the discontinued Pelican-heritage lineup: FactoryPure listed the NS6 at $1,629 (out of stock) in July 2026, while smaller dealers like Healthier Elements still showed NS3/NS6 units in stock around $1,699. The certification story remains genuinely strong — IAPMO-certified to NSF/ANSI 42 and 61, plus DVGW certification for 99.6% scale prevention, the German standard that actually measures scale performance. Remember what NaturSoft is, though: a template-assisted crystallization conditioner, not a softener. It prevents scale but your water will still test hard.

Where can I actually buy Pentair water filtration in 2026?

Three channels. First, the pro channel: pentair.com's home water treatment section now has no cart and no prices — it routes you to a 'Contact a Local Pro' dealer locator for softeners, whole-home systems and iron filters. Second, big-box remnants: Home Depot and Lowe's still list PC600-family systems, combos and replacement media while stock lasts. Third — and most practical — Amazon, where Pentair's cartridge and housing brands live on: Pentek sediment and carbon cartridges (DGD-5005, RFC-BB, EP-20BB, P5), OMNIFilter housings and systems, and the FreshPoint reverse osmosis line. For most shoppers searching 'Pentair water filter,' a Pentek cartridge in a standard housing is the product you'll actually end up buying.

What replacement filters does my Pelican or Pentair Pelican system need?

The PC600 takes PC600-R replacement carbon media (about $242.50 at Home Depot) on a 5-year or 650,885-gallon cycle — the PC1000's cycle is 5 years or 1,301,770 gallons — plus a sediment pre-filter change every 6 to 9 months, which typically costs around $22. Those official gallon figures come straight from pentair.com's product pages. Pentair maintains a legacy-owner support line (877-842-1635) and continues to sell PC600-R, PC1000-R media and PC40-P prefilters, so an existing system remains fully serviceable even though the systems themselves are discontinued.

Pentair vs SpringWell — which whole-house filter should I buy in 2026?

For a new purchase, SpringWell wins on availability alone: the CF1 is in production, published-price (roughly $1,016–$1,144 depending on promotions in 2026 reviews), rated for 1,000,000 gallons of media life, and carries a lifetime warranty on tanks and valves versus Pentair's 5-year/gallon-capped warranty on the legacy PC line. The Pentair PC600 was a genuine rival — IAPMO-certified, 10 GPM, 97% chlorine reduction — but buying a discontinued system means betting on clearance stock. Where Pentair still deserves the nod is components: Pentek cartridges and OMNIFilter housings are the industry-standard way to build a cheap, flexible sediment-plus-carbon setup for a fraction of a tank system's price.

Is the Pentair Iron & Manganese filter any good for well water?

The chemistry is respected — WaterFilterGuru's 2026 well-water roundup ranks the Pentair (formerly Pelican) Iron & Manganese Filter Combo first for manganese, crediting its four-stage design (5-micron sediment, chlorination, greensand and carbon) with removing up to 10 PPM of combined iron and manganese, at a steep price around $3,600. The WF4 and WF8 pages remain live on pentair.com with no price, dealer-quoted like the rest of the line. If that's out of budget, air-injection systems from brands with published prices handle most private wells — see our iron filter guide for the field.
