The Vertex IsoTwist is an under-sink reverse osmosis (RO) filter system. Optimized to treat municipal water using the existing water pressure, the system’s slim design, high-production membrane, quick-twist filter cartridges and 3/8-in. quick-connect O-ring seal fittings offer advantages for the dealer and customer.
It comes with a 50-gal-per-day RO membrane to meet the demands of residential users. With four- and five-stage models available, dealers can choose the model that best fits the customer’s needs. The four-stage model typically is used in municipal water applications with low to medium use, while the five-stage model is designed to handle difficult water situations or high usage.
Designed with quarter-turn quick-twist pre- and post-filters on a slim bracket, the system is easy to mount and takes up less space under the sink. The disposable quick-twist filter cartridges and RO membrane assembly make installation and filter replacement quick, easy and sanitary.
The dual O-rings on each quick-twist filter cartridge ensure a fresh and dependable seal at each filter change and cannot be over tightened. There is no need to clean or sanitize the filter housing sumps.
The 3/8-in. tubing allows high flows to the faucet, ensuring customer satisfaction. IsoTwist comes ready to install with connection hardware, tubing, faucet and instruction manual.
The system has been submitted to the IAPMO Platinum Certification Program for third-party testing to NSF/ANSI Standard 58 to ensure dealer confidence in quality and reliability.
The IsoTwist is part of the PureWaterMachine line of under-sink RO filter systems, including four- and five-stage systems, with low pressure, sanitation and leak detection options. Vertex manufactures RO systems, bottle-less and bottled water coolers, and conditioning systems for residential and commercial applications.
