Independently verified by WQA & NSF/ANSI to prove material safety and performance.
A 5-Stage Process for Certified-Clean Water
The MicroMax 8500 is engineered for performance, reliability, and simplicity.
1
Stage 1: Sediment Filter
Removes dirt, rust, sand, and other large particles that affect the clarity and quality of your water.
2
Stage 2: Pre-Carbon Filter
Removes chlorine, tastes, and odors. This stage protects the system's core membrane from chemical damage.
3
Stage 3: RO Membrane
The "heart" of the system. This ultra-fine membrane rejects up to 99% of dissolved solids, including heavy metals (lead, arsenic), PFAS, and more.
4
Stage 4: Post-Carbon Filter
A final "polishing" filter to ensure no lingering tastes or odors are left behind before the water reaches your glass.
5
Stage 5: Alkalizer Filter
Adds back a blend of healthy, natural minerals (like calcium and magnesium) to raise the pH for that smooth, refreshing, balanced taste.
The Secret to Better-Tasting Water
Ever had RO water that tastes "acidic" or "flat"? It's a common complaint with online brands that cut costs.
The MicroMax 8500 includes an advanced Alkalizer Mineral Filter as its final stage. This filter adds back a blend of natural minerals (like calcium and magnesium) to raise the pH, resulting in water that is perfectly balanced, refreshing, and clean-tasting.

The Actual Filter: Your Final Stage for Better Taste
The Alkalizing Process: What's Inside
Go Beyond Online Claims
Here's the expert secret: Many online brands use the word "Certified" as a marketing claim. But a real certification is a public listing you can verify on sites like NSF.org.
Don't just trust a claim. Demand the listing. Here’s a transparent look at the difference.

Puronics MicroMax 8500
Verifiable Public Listing
Not just a 'claim.' The MicroMax 8500 system is publicly listed on WQA & NSF.org for total transparency.
Certified for Safety & Performance
Certified for both material safety (NSF 372 & 58 - won't leach) and performance (NSF 42, 53, 58, & 401 - removes contaminants).
Mineral Alkalizer Filter
Adds healthy minerals back to raise pH for a smooth, refreshing taste.
10-Year Comprehensive Warranty
Includes 10 years on parts, 10 years on the system, and 10 years on labor.
Local Expert Support
Installed and serviced by a licensed, insured Tucson plumber.
Easy DIY Filter Changes
Simple 1/4-turn 'twist-and-lock' cartridges. No tools, no mess, and no need to shut off the water. Save money by doing it yourself.
Typical Online-Only Brands
Misleading "Certified" Claims
Uses the word 'Certified' as a marketing tactic, but often lacks a verifiable public listing.
Incomplete Safety Certification
May only be "tested" for performance (like TDS), but often lacks material safety certification (NSF 58, 61 & 372). This is a scary risk, as the system itself could leach lead or chemicals.
No Alkalizer
This cost-cutting measure often leads to an "acidic" or "dead" taste.
Limited, Parts-Only Warranty
What good is a parts warranty if you're left to pay for expensive labor?
Impersonal Call Center Support
When something goes wrong, your support is an 800-number, not a local expert. You're left to find and pay a plumber for labor, or ship parts out-of-state.
Difficult Filter Changes
Often require special tools, shutting off the water, and dealing with hard-to-remove filter housings, forcing you to call a plumber.
Certified for Safety & Performance
When it comes to your family's water, proof matters more than promises. The MicroMax isn't just "tested"—it's independently certified by the Water Quality Association (WQA) to meet or exceed multiple NSF/ANSI standards for both performance and safety.
NSF/ANSI 58: Certified for Reverse Osmosis system performance.
NSF/ANSI 53: Reduces health-related contaminants (PFAS, heavy metals, VOCs).
NSF/ANSI 42: Reduces aesthetic effects (chlorine, taste, odor).
NSF/ANSI 401: Reduces emerging contaminants (pharmaceuticals, chemicals).
NSF/ANSI 372: Certified for lead-free materials.
Your 10-Year, All-Inclusive Warranty
Online brands offer limited, parts-only warranties, leaving you to pay for expensive labor. We believe in the MicroMax 8500 product and our service.
10-Year System
Full warranty on the system manifold.
10-Year Parts
Complete coverage on all parts and components.
10-Year Labor
We cover the cost of labor for any warranty-related service.
"What I see too often is homeowners buying low-cost systems online that aren't built for safety and performance, but to a 'price point' to sell to the masses. After years of seeing what works and what doesn't, I can say with confidence... the Puronics MicroMax 8500 is a system you can rely on to deliver the results you expect."
