Clean drinking water systems, matched to your home.
From a renter-friendly under-sink system to a fully certified reverse osmosis build, this is every real drinking water solution compared in one place — what each one removes, what it costs, and which fits your water, your home, and your budget. No guesswork, no upsell games.
Which are you?
The right drinking water system depends on your situation more than your budget. Find yourself below and jump straight to the fit — or keep scrolling to compare everything.
I rent
No drilling, nothing permanent, and it moves with you at lease-end.
I own my home
A permanent, low-maintenance under-sink system with minerals back in.
Big family, high use
On-demand water at the tap that beats refilling pitchers all day.
I'm on well water
Wells need a system matched to your specific water — let's look together.
PFAS or fluoride worries me
You want third-party certification for the exact contaminant you're facing.
Every drinking water option, side by side.
Ordered from our best-value under-sink system up to the most complete certified build. Every option here is real reverse osmosis that adds minerals back — so your water is clean and tastes the way water should.
Pur-Alkaline RO
The easiest real step up from a pitcher — reverse osmosis with an alkaline mineral stage built in, so it never tastes flat.
The Hydration Stack
Our best-selling setup — the certified MicroMax 8500, the Sango Coral remineralizer, and the UMH Pure structuring device in one system.
MicroMax 8500
Our broadest certification — PFAS, 96.5% fluoride, lead, arsenic, and pharmaceuticals, third-party verified.
MicroMax 7000
Certified reduction of lead, arsenic, chromium, nitrates, and 97.5%+ of dissolved solids. Not certified for PFAS.
GoodFor Sango Coral
Adds back 70+ trace minerals from Okinawan coral after any RO — the taste upgrade most owners wish they'd added sooner.
What each system actually removes.
The GoodFor Company is a consultation-first water filtration company that matches homeowners and renters to certified drinking water systems based on their actual water data — rather than selling one setup to every home. Here's the whole drinking lineup compared on what matters: what it removes, whether it's independently certified, whether it puts minerals back, and what it really costs.
| Factor | Pitcher filter | Pur-Alkaline RO | MicroMax 7000 | MicroMax 8500 |
|---|---|---|---|---|
| Install | None | Under-sink | Under-sink | Under-sink |
| Chlorine taste & odor | Yes | Yes | Yes | Yes |
| Lead | Some | Reduces | Certified | Certified |
| PFAS (PFOA/PFOS) | No | Reduces | Not certified | Certified |
| Fluoride | No | Reduces | Reduces | 96.5% certified |
| Arsenic / nitrates | No | Reduces | Certified | Certified |
| Dissolved solids (TDS) | No | 90%+ | 97.5%+ | 97.5%+ |
| Minerals back in? | No | Built in | Add Sango | Add Sango |
| Independently certified? | Varies | Reduces, not NSF | NSF 42·58·372 | NSF 42·53·58·401·372 |
| Upfront | ~$30–50 | $699 | $997 | $1,275 |
| Annual filters | $150–400 | ~$60–120 | ~$140–339 | ~$140–339 |
| Warranty | 90 days | Manufacturer | 10-year tank/valve | 10-year tank/valve |
"Reduces" = lowers the contaminant but not third-party certified for that claim. "Certified" = independently tested and listed. For the full reverse osmosis decision — how the membrane works, tank vs. tankless, waste ratio — see our reverse osmosis buying guide.

Clean water should still have minerals.
Reverse osmosis is the most thorough way to filter drinking water — but it removes beneficial minerals like calcium and magnesium along with contaminants, which can leave the water tasting flat and slightly acidic. That's not harmful (most of your minerals come from food), but it's the number-one reason people either love or regret an RO system.
The fix is remineralization, and every system we recommend handles it. The Pur-Alkaline RO builds an alkaline mineral stage right in. The MicroMax systems pair with the Sango Coral, which adds back 70+ trace minerals from fossilized Okinawan coral. Either way you get water that's clean and tastes the way water should.
Alkaline describes pH; remineralization describes what's added back — a good mineral stage does both at once. If you're specifically shopping mineral cartridges, our alkaline & mineral filters collection has the full range, and our guide to alkaline vs. remineralization filters explains which fits your water.
You don't have to choose between a pitcher and drilling your countertop.
The simplest real upgrade is the Pur-Alkaline RO ($699) — a 6-stage under-sink reverse osmosis system that connects with a faucet adapter, runs with no electricity, and adds minerals back so the water never tastes flat. Want third-party certification? Pair any MicroMax system with our 2-in-1 dual faucet, which replaces your existing kitchen faucet and gives you two handles — one regular, one purified RO — with no second hole to drill and nothing permanent.
When your lease ends, swap your original faucet back and the whole system moves with you. It's one of the only renter-friendly under-sink RO setups available. We always recommend a licensed plumber for installation.
What it really costs — and who installs it.
A certified under-sink system runs $699–$1,275 upfront, and within a year or two it's cheaper than the bottled-water or pitcher habit it replaces.
Cheaper over time
RO filters last 12+ months. A family's bottled-water habit can run $1,000–1,500 a year — an RO system pays for itself fast.
Ships nationwide
Product and shipping only; installation isn't included in website prices. The systems are built for a straightforward DIY install with our team a call away.
Full-service install
Our licensed plumbers install in Southern California, Houston, Austin, Tampa, and Miami/Ft. Lauderdale.

Clean drinking water, answered.
What's the best system for clean drinking water at home?
For most homes it's an under-sink reverse osmosis system, because RO reduces the widest range of contaminants — lead, PFAS, fluoride, arsenic, nitrates, and dissolved solids — then adds minerals back for taste. The Pur-Alkaline RO ($699) is the easiest value pick; the MicroMax 8500 ($1,275) is the most certified.
Is reverse osmosis water safe to drink?
Yes — it's among the cleanest drinking water you can make at home. The common worry is that RO removes minerals; that's true, but most mineral intake comes from food, and every system we recommend adds minerals back either built in (Pur-Alkaline) or with the Sango Coral.
What does a clean drinking water system cost?
A certified under-sink RO system runs $699–$1,275 upfront with roughly $60–$339 a year in filters. Over five years that's typically cheaper than a bottled-water or pitcher habit, which can exceed $1,000 a year for a family.
Do I need certification, or is "reduces" good enough?
If you're targeting a specific contaminant — especially PFAS or fluoride — look for third-party NSF/ANSI certification with the standard number, not only a "reduces" claim. The MicroMax 8500 is certified to NSF/ANSI 42, 53, 58, 401, and 372. The Pur-Alkaline reduces a broad range but isn't independently certified, which is why it's our value pick rather than our certified pick.
What's the difference between the Pur-Alkaline, MicroMax 7000, and 8500?
The Pur-Alkaline ($699) is the best-value RO with minerals built in but isn't NSF-certified. The MicroMax 7000 ($997) is certified (NSF/ANSI 42, 58, 372) but not for PFAS. The MicroMax 8500 ($1,275) is the most certified — including PFAS, 96.5% fluoride, and pharmaceuticals. Add the Sango Coral to either MicroMax for minerals.
Can renters install a drinking water system?
Yes. The Pur-Alkaline RO installs with a faucet adapter, and any MicroMax pairs with our 2-in-1 kitchen + RO faucet, which uses your existing faucet hole — no drilling, nothing permanent, and it reverses out at lease-end. See our renter-friendly options.
Does a drinking water system remove PFAS and fluoride?
Reverse osmosis is one of the most effective home methods for both, but only if the system is certified for them. The MicroMax 8500 is certified under NSF/ANSI 53 for PFOA/PFOS and NSF/ANSI 58 for 96.5% fluoride reduction. Pitchers and faucet filters generally are not.
Why does RO water taste flat, and how do I fix it?
RO removes minerals along with contaminants, which flattens the taste. The fix is remineralization — built into the Pur-Alkaline, or added with the Sango Coral cartridge after any RO. Here's how to remineralize RO water.
Is a pitcher filter good enough?
A pitcher is a fine stopgap for renters using little water, but the filter costs add up fast and most pitchers don't remove much beyond chlorine taste. See our reviews of the Brita and ZeroWater pitchers for exactly where they fall short.
What about whole-house filtration versus a drinking system?
A drinking system treats the water you drink and cook with; a whole-home system treats every tap — shower, laundry, and appliances. Many homes do both: whole-home for the house, an under-sink RO for the best drinking water. A consultation is the fastest way to see what your water actually needs.
Do you install, or is it DIY?
Both. GoodFor ships nationwide (product and shipping only) with systems built for DIY install, and offers full-service installation in Southern California, Houston, Austin, Tampa, and Miami/Ft. Lauderdale. We always recommend a licensed plumber where one's required.
How do I know which system is right for my water?
Start with what's in your water. Book a free consultation and we'll pull your local water-quality report and match you to a certified system — or if you'd rather read first, our reverse osmosis buying guide walks through the whole decision.
