What Makes the Ultra Pro Ultrafiltration Different
5½ Miles of Hollow Fiber
Each modular unit contains up to 5½ miles of hollow fiber lumens and up to 194 square feet of filtration surface — capturing the tiniest contaminants while maintaining high flow rates up to 10.5 GPM.
Auto Backwash · Low Waste
Fully automatic, adjustable cleaning cycles. Backwashing only needed once a day for 5 minutes, with industry-leading 1–2% waste-water discharge during cleaning. Outside-in flow minimizes clogging risk.
NSF/ANSI 53 & 61 Certified
Membrane filters certified to NSF/ANSI 53 and 61. Tested for 4-log cyst reduction and independent third-party tested for 6-log bacteria reduction. No chemicals required.

Why Pure Water Systems for the Ultra Pro Ultrafiltration
Removes What Others Miss
Microplastics, tannins, and colloidal iron pass through standard filters. The 0.02 micron hollow-fiber membrane captures them all — no matter how small.
No Cartridge Replacements
The self-cleaning backwash system eliminates ongoing cartridge costs — a significant long-term saving compared to standard filter systems requiring multiple replacements per year.
Up to 10.5 GPM Flow Rate
High-capacity hollow-fiber design delivers up to 10.5 GPM with a wide range of flowrates available across modular configurations — maintaining full household water pressure with no sacrifice in flow rate.
Chemical-Free Purification
Master Water’s UltraPro membrane technology delivers pristine water without chemicals — no chlorine, no UV, no chemical handling. Pure physical filtration at the smallest possible scale. Water is treated even when the power goes out — uses existing water pressure to operate, no additional pump or motor needed.

The 3 C's of Northern Nevada Water
Standard softeners only address hard water. The Reionator Pro Ultra tackles all three contaminant categories that plague local water supplies — the reason one system can replace several.
Calcium (Hard Water)
Mineral deposits that destroy appliances, clog pipes, and leave unsightly scale on fixtures and glass.
- •Shortens water heater & dishwasher life
- •Scale on glass, faucets & shower doors
- •Higher detergent & soap consumption
Chlorine & Chloramines
Municipal disinfectants that kill bacteria — but form harmful disinfection byproducts at the tap.
- •Unpleasant taste & chemical odor
- •Harsh on skin, hair & fixtures
- •Creates trihalomethane byproducts
Chemicals & Contaminants
Pharmaceuticals, VOCs, PFAS, lead, arsenic and trihalomethanes — contaminants with documented health effects.
- •VOCs linked to cancer & organ damage
- •Lead & arsenic — serious health risks
- •PFAS — reproductive & developmental effects
The 5-Stage Filtration Process
A sophisticated five-stage sequence engineered for maximum efficiency — from intelligent flow control to automatic regeneration, every stage is designed to outperform single-purpose systems.
Triton Control Valve
Industry-leading valve that anticipates usage patterns and self-initiates cleaning cycles.
TechSorb Media
Tackles chlorine, chloramines, VOCs, disinfection byproducts & emerging contaminants.
AquaHelix™ Plate
Proprietary distribution system that ensures optimal contact time for maximum treatment.
Dual Resin Bed
TechSelect & TechSoft handle residual chlorine, sulfates, nitrates, hardness, iron & lead.
Auto Regeneration
AquaHelix™-assisted cleaning cycle for efficient resin renewal and reduced water waste.
