Pentair water filter review: FreshPoint, OMNIFilter and Pelican
5 filters: 2 under-sink filters, 2 RO systems and 1 whole-house system, $139.99 to $669.29. Pentair water filters carry two sets of listings, and you need both. As of October 15, 2026, NSF lists the OMNIFilter RO2050 and FreshPoint GRO-575 reverse osmosis systems to NSF/ANSI 58 for arsenic, fluoride, lead and TDS, and the FreshPoint F2000 and Easy Flow under-sink filters to NSF/ANSI 53 for lead and cysts. The PFAS claims are in a separate IAPMO certificate: total PFAS for the GRO-575 and F2000, PFOA/PFOS for the Easy Flow. Pelican’s website now redirects to pentair.com.

Listing: "certified" counts only substances in the certifier's public listing for that model. Pentair's own reduction claims that are not in a listing are shown separately on each model page.
Verdict: which Pentair filter to buy
At $162.23 (checked Oct 15, 2026), it’s the lowest-priced under-sink reverse osmosis system in our database, with the same NSF/ANSI 58 claims as the GRO-575. The catch is output: NSF lists 15.04 gallons a day, and the manual gives an 8.44% efficiency rating.
It’s the only Pentair model listed for both. It costs $669.29 (checked Oct 15, 2026) from a third-party seller, and NSF lists 21.08 gallons a day, not the “up to 75” on the spec sheet.
It filters the cold line to the faucet you already have, at 1.4 gpm in the NSF listing, for $139.99 (checked Oct 15, 2026). Leaks are the risk: 5 of 6 Amazon reviews that mention leakage are negative.
Lead, cysts, total PFAS and microplastics, for $279.55 (checked Oct 15, 2026). It needs its own faucet hole and flows 0.6 gpm.
None of the four Pentair models here is listed for either, and Pentair’s Easy Flow FAQ says it doesn’t reduce chloramines.
Alternatives with a certifier listing
These fill the gaps in Pentair’s listings: chloramine and VOCs under the sink, more water a day from reverse osmosis, and VOCs for the whole house.
Listings and prices checked October 2026; Pentair models as of October 15, 2026
The AquaTru Under Sink is the reverse osmosis swap: its data sheet gives 54 gallons a day at 25% efficiency, against the RO2050’s 15.04 and 8.44%. The Claryum Direct Connect connects to your faucet line like the Easy Flow and adds chloramine and VOCs. The Epic Smart Shield is listed for chloramine and VOCs for less, without PFAS. For the whole house, the HealthShield is listed for the same five PFAS as Pentair’s FloPlus Protect 20BB plus VOCs, at about $1,897 a year against $187. The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.

Pentair lineup: FreshPoint, OMNIFilter, FloPlus and Pelican
Pentair sells home water filters under several names: FreshPoint and OMNIFilter under the sink, Pentek and FloPlus cartridges for whole-house housings, and Everpure. The table shows the models I could match to a listing and a dated Amazon price.
| Model | Type | Price | Listed for |
|---|---|---|---|
| OMNIFilter RO2050 | Reverse osmosis, 4 stages, 2.8-gallon tank | $162.23 | Arsenic, fluoride, lead, TDS and cysts (NSF) |
| FreshPoint GRO-575 | Reverse osmosis, 5 stages, 4.4-gallon tank | $669.29 | Arsenic, fluoride, lead, TDS and cysts (NSF); total PFAS (IAPMO) |
| FreshPoint F2000 | Two carbon blocks, own faucet | $279.55 | Lead, cysts and microplastics (NSF); total PFAS (IAPMO) |
| FreshPoint Easy Flow | One carbon cartridge, your faucet | $139.99 | Lead and cysts (NSF); PFOA/PFOS (IAPMO) |
| FloPlus Protect 20BB | Whole house, one 20-inch carbon block | $258 | PFOA, PFOS, PFHxS, PFNA and PFHpA (IAPMO) |
The RO2050 page and GRO-575 page on pentair.com describe the systems but don’t sell them. Amazon sellers differ: the Easy Flow is sold by Amazon.com, the others by third-party sellers.
Pelican is now Pentair. Pelican’s website redirects to pentair.com, and Pentair’s Pelican page says “the Pelican brand has evolved into Pentair Water Solutions.” Pentair still supports legacy Pelican systems, and new whole-house systems go through local dealers with its True Blue PRO badge. I found no listing under the Pelican name at NSF, IAPMO or WQA.
Everpure is a Pentair brand too: NSF lists Everpure systems under the same company, Pentair Residential Filtration. See our Everpure review.
Is Pentair NSF certified? NSF and IAPMO listings
Yes. On October 15, 2026, I read the listings of Pentair Residential Filtration, LLC at NSF, IAPMO and WQA. NSF lists the systems by standard. The PFAS claims are only in IAPMO’s certificate. WQA lists Pentair Water India, not the US models.
- NSF, NSF/ANSI 58: 13 claims for the GRO-575B, among them arsenic, fluoride, lead, hexavalent chromium, radium 226/228, cysts and TDS. The RO2050 has the same list without cysts, and NSF lists its cyst claim under NSF/ANSI 53.
- NSF, NSF/ANSI 53: lead and cysts for the F2000 and Easy Flow, plus atrazine for the F2000 and GRO-575.
- NSF/ANSI 42 for chlorine taste and odor: the F2000, Easy Flow and GRO-575. NSF/ANSI 401 for microplastics: the F2000 and GRO-575.
- IAPMO certificate 19673, NSF/ANSI 53: total PFAS for the F2000 and GRO-575, PFOA/PFOS for the Easy Flow, and five PFAS for the FloPlus Protect 20BB whole-house system.
Some claims on Pentair’s pages aren’t in a listing. The F2000 page gives 98.8% for chloroform, a stand-in for VOCs, but NSF lists no VOC claim for it. A listing doesn’t mean the substance is in your tap water: a water test tells you what to filter for. The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.
Pentair reverse osmosis: gallons per day and wastewater
The GRO-575B spec sheet says the membrane makes “up to 75 gpd.” NSF lists the system at 21.08 gallons a day. The same spec sheet prints 30.57 gallons a day and a 51.17% recovery rating; 30.57 is the rate NSF lists for the GRO-475B, a sister model. For planning, use the NSF figure.
The RO2050 is plainer. NSF lists 15.04 gallons a day, and the RO2050 manual gives an 8.44% efficiency rating and an 18.2% recovery rating. Efficiency is measured with the tank in use: at 8.44%, about 11 gallons go to the drain for each gallon you keep. The GRO-575B manual doesn’t publish an efficiency rating.
Both need 40 to 100 psi of water pressure, a hole for the separate faucet and a drain connection. The RO2050 comes with a 2.8-gallon tank and a TDS test kit. The GRO-575 comes with a 4.4-gallon tank and an air-gap faucet. Reverse osmosis from every brand is compared in the best reverse osmosis systems.
Pentair whole-house filters: FloPlus Protect and FloPlus Heavy Duty
The FloPlus Protect 20BB is Pentair’s whole-house PFAS filter: one carbon block in a 20-inch Big Blue housing. Pentair’s cartridge page says it’s certified by IAPMO R&T to NSF/ANSI 53 for PFOA and PFOS “when used in the FloPlus Protect 20BB system.” IAPMO’s certificate lists PFOA/PFOS, PFHpA, PFHxS and PFNA for the system, at 40,000 gallons and 5 gpm. On Amazon on October 15, 2026, the system was $258.00 and a replacement cartridge $187.46, rated for about 12 months. Its card is FloPlus Protect 20BB, and it’s compared with Aquasana and SpringWell systems in the best whole-house water filters.
The FloPlus Heavy Duty systems and cartridges are listed by NSF to NSF/ANSI 53 for cysts only. Pentair’s whole-house carbon systems are marked discontinued. For lead at the kitchen tap, see lead-certified water filters.
Pentair replacement filters: how often and what they cost
I priced each system’s filters on Amazon and spread the membrane over its rated life.
| System | Filters | How often | Per year |
|---|---|---|---|
| FreshPoint GRO-575 5-Stage Reverse Osmosis | F1GC $35.48, FDF1 $43.00, F2B1/F2B2 pair $87.27, GRO75 membrane $108.40 | Pre- and post-filters 1 year or 675 gallons, RO membrane 18 months (brand figure) | $238 |
| OMNIFilter RO2050 4-Stage Reverse Osmosis | ROR2050 filter kit $22.09, OM1 membrane $50.13 | Sediment and carbon pre-filters 6 months, inline carbon post-filter 12 months, membrane 18 to 24 months (manual) | $78 |
| FreshPoint F2000 Under Counter Filter | F2B1/F2B2 pair $87.27 | 675 gallons or 1 year (NSF listing; brand) | $87 |
| FreshPoint Easy Flow Under Counter Filter | RC-LCT $87.03 | 3,000 gallons or 1 year (NSF listing; brand) | $87 |
The RO2050 figure counts two ROR2050 kits a year, since the sediment and carbon filters last 6 months, and the GRO-575 figure counts its membrane every 18 months. The F2000 pair is rated for 675 gallons, under 2 gallons a day over a year, so a family that drinks and cooks with it will change it sooner. The Easy Flow cartridge is rated for 3,000 gallons. Pentair’s warranty on replacement cartridges is 30 days.
What Pentair owners say
Pentair systems have few Amazon ratings. I read the review summaries for all four on October 15, 2026.
The RO2050 gets the best marks. On Amazon, it has 4.1/5 from 37 ratings. 11 of 12 reviews that mention water quality are positive, and 8 of 9 that mention how it works.
The Easy Flow leaks for some. It has 3.6/5 from 48 ratings on Amazon, and 26% of them are one star. 5 of 6 reviews that mention leakage are negative, and 4 of 6 that mention installing the filter.
The F2000 and GRO-575 have too few ratings to read much into: 9 and 7 on Amazon.
Pentair warranty and returns
Pentair’s warranty page gives 1 year on FreshPoint, under-sink and reverse osmosis systems, and on whole-house housings and systems. Replacement cartridges get 30 days. Pentair no longer requires registration: keep your proof of purchase.
All four systems were returnable within 30 days on Amazon on October 15, 2026. The seller sets the return terms, so check the seller name before you buy.
