Flagship under-sink reverse osmosis for chemical-heavy city water. MicroMax 8500 is a 5-stage RO (4 easy-change cartridges) that pairs a dual-carbon prefilter with a precision RO membrane to tackle contaminants most basic filters miss.
Built to help reduce PFAS (PFOA/PFOS), pharmaceuticals (NSF/ANSI 401), VOCs, chlorine/chloramine byproducts, and heavy metals like lead, arsenic (V) and chromium-6—so your kitchen gets better-than-bottled water for drinking, cooking, coffee and tea.
The 8500 fits neatly under the sink with a dedicated RO faucet, a pressurized storage tank for on-demand pours, and quick-change RO filters that are renter-friendly and easy to maintain.
If you’re searching for a PFAS removal system, fluoride reduction RO, or a dual-carbon, 5-stage reverse osmosis system designed for municipal water contaminants, this is our go-to choice.

- Stage 4:W-PN-8004 (yellow)
- Pressurized storage tank (approx. 3.2 gal pre-charged 5–7 psi)
- Installation kit & lines + quick-start guide
- Lifetime product support from GoodFor
- Rated production: ~35 GPD(membrane) — system ~16 GPD @ 50 psi, 77°F
- Efficiency / recovery: ~24% / ~28% (≈23.8% / 27.9%)
- Operating pressure / temp: 30–100 psi / 40–100°F (4–38°C)
- Max feed water: TDS 2000 ppm · hardness 10 gpg · free chlorine 3.0 ppm
- Feed pH range: 4–10
- Tank capacity: 3.2 gal (pre-charge 5–7 psi)
- Drain (reject) flow: ~3–5× product flow Connections/fit:
- Tubing / fittings:1/4" & 3/8" push-fit connections
(Actual production varies with pressure, temperature, TDS, and membrane age. Arsenic reduction applies to pentavalent arsenic (As V) and requires detectable free chlorine at the inlet.)
- NSF/ANSI 58 (RO health): arsenic (V), barium, cadmium, chromium III/VI, copper, fluoride, lead, selenium, TDS, turbidity/cysts
- NSF/ANSI 42 (aesthetic): chlorine taste/odor; particulate (Class III ≥5 μm)
- NSF/ANSI 53 (health): PFOA/PFOS; VOC surrogate (chloroform proxy)
- NSF/ANSI 401 (emerging contaminants – Group A): BPA, estrone, ibuprofen, naproxen, nonylphenol
- NSF/ANSI 372 (lead-free) · WQA Gold SealArsenic claim applies to pentavalent arsenic (As V) with detectable free chlorine at the inlet.[View certificates & performance data →]
Under-sink installation with a dedicated RO faucet; typical setup 60–90 minutes (handy DIYer or pro).
Storage Tank Capacity: 3.2 gallons
Water Pressure Limits: 30 psi
Dimensions
WIDTH: 16”
DEPTH: 5”
HEIGHT: 16”
Cartridge map & parts:
- W-PN-8001 (blue)
- W-PN-8002 (red)
- W-PN-8003 (green)
- W-PN-8004 (yellow)
Cadence:
- 12 months (2,500 gal) or when taste/flow declines
- 3–5 years (shorter with high pH/TDS; longer with gentle water)
Quick-swap tips: Shut off inline valve → relieve pressure → twist-lock cartridges straight down/up → check for leaks → sanitize/purge.
Pressure matters: Keep feed ≥30–40 psi (booster recommended below this) to protect membrane life.

Frequently Asked Questions
Yes—validated under NSF/ANSI 53 for PFOA/PFOS and NSF/ANSI 401 for select emerging contaminants (BPA, estrone, ibuprofen, naproxen, nonylphenol).
Yes. The reverse osmosis membrane step reduces fluoride along with heavy metals and other dissolved contaminants.
The system operates between 30–100 psi; a booster pump is recommended if your pressure is under ~30–40 psi.
Unlike simple carbon filters, RO systems reduce virtually everything dissolved in your water—chlorine, heavy metals, fluoride, PFAS, pharmaceuticals. Filters like pitchers or faucet units only address taste, chlorine, and sediment.
Absolutely. Choose the dual kitchen/RO faucet option to avoid drilling. It’s removable and landlord-friendly.
Carbon cartridges are typically replaced every ~18 months; the RO membrane lasts ~3 years, depending on water quality and use.
During purification, a small drain stream carries away rejected contaminants—typically about 3–5× the product flow.
Yes! Add the Sango or UMH Pure as part of our Hydration Stack for remineralized, structured water.
Yes, you can use any plumbing professional to install this for you. The system comes with detailed instructions and our team is always just a phone call away. No long wait times!
