About this product

The Vertex 5 Stage Point of Use Reverse Osmosis Purifier is a high-performance water appliance that installs under your sink.

The Vertex five-stage Reverse Osmosis water purification system uses advanced RO Membrane technology to remove dissolved molecular contaminants from tap water. Five stages block high sediment contamination to clean even the dirtiest water. Reverse Osmosis filtration cleans water by taking out the totally dissolved solids (TDS) which contaminate water. Although city water treatment removes the dirt and debris and adds chlorine to prevent the spread of diseases, it does not remove the dissolved solids from the water. And, with the increasing pollution of our surface and ground water with contaminants, such as lead, mercury, and chromium-6, as well as the naturally occurring harmful contaminants such as arsenic, fluorides and sulfides found in some areas of the country, it is more important than ever to have a way to remove these contaminants at the point of use.

5 Stages of Filtration in the PT-4.0-5 PureWaterMachine RO System

The PureWaterMachine RO Drinking Water System comes complete, ready to install with instructions. All 5-stages are pre-assembled and tested. The faucet, inlet water valve, drain saddle connection, storage tank valve and color coded plastic tubing for under-sink installation are all included.

  • Stage 1 - Sediment Filter | 5-micron polyspun cartridge - The 5 micron polyspun filter takes out suspended solids such as dirt, rust, sand, and pipe scale.
  • Stages 2 & 3 - Double Activated Carbon Block Filters, 10-micron - Activated carbon block filter removes chlorine, bad tastes and odors.
  • Stage 4 - Reverse Osmosis Membrane, 36 GPD GPD - The heart of the Vertex PureWaterMachine is the reverse osmosis membrane. RO technology removes on average 95% of the dissolved solids in your water. Dissolved solids are not removed by municipal water treatment. This is why the Vertex PureWaterMachine RO System is an important safety factor for the water you drink and use in your cooking. City water pressure is used in the reverse osmosis membrane to force the water molecules through the membrane, but the larger contaminant molecules are kept behind and flushed to the sewer. The clean water goes into the storage tank and is held there ready for use. An autovalve turns off the water when the tank is full. The tank is pressurized with a bladder which pushes the water out through the final filter.
  • Stage 5 - Granular Activated Carbon post-filter - When the faucet is opened, clean water from the storage tank flows through the final polishing filter of activated carbon and into the faucet for your use. This special faucet is installed on your sink to dispense safe, good tasting drinking water which is especially good for coffee, tea and drinks.
    *Optional Stage 5 GAC/Calcite filter - Brings the water pH back up to 7. Typically, reverse osmosis purification removes minerals which causes the pH level to drop. This optional post filter will replace the mineral and will raise the pH to (around) 7.

NOTE: Do not use with water that is microbiologically unsafe, or of unknown quality, without adequate disinfection before or after the system.

Best for

  • Homes, offices, and breakrooms needing high-quality purified drinking water
  • Locations with concerns about chlorine, dissolved solids (TDS), chemicals, and contaminants in tap water
  • Users wanting a reliable under-sink RO system for cooking, beverages, and everyday hydration
  • Small households or light-duty commercial spaces requiring up to 36 gallons per day of purified water
  • Facilities upgrading from basic carbon filtration to true reverse osmosis performance
  • Anyone seeking a compact, efficient RO system that fits easily under most sinks

Installation tips

  • Install the system under the sink on a level surface with access to the cold-water line and drain.
  • Allow enough clearance to access the filter housings and RO membrane for future replacements.
  • Shut off the cold-water supply, then connect the feed adapter and tubing according to the provided diagram.
  • Mount the RO faucet on the sink or countertop and connect the tubing securely.
  • Connect the drain saddle to the sink drainpipeโ€”ensure proper alignment to prevent leaks.
  • After installation, flush the system for the recommended time to prime the filters and membrane.
  • Check all connections for leaks before placing items back under the sink.

Note: Warranty on system is void unless installed by licensed plumber.

Frequently asked questions

How much purified water can the PT-4.0/5 produce per day?
The system produces up to 36 gallons per day under standard conditionsโ€”ideal for homes, breakrooms, and small offices.

How often do the filters need to be replaced?
Sediment and carbon filters typically last 6โ€“12 months, while the RO membrane usually lasts 2โ€“3 years, depending on water quality and usage.

Does the PT-4.0/5 remove chlorine, chemicals, and dissolved solids?
Yes. The PT-4.0/5 uses multi-stage filtration plus RO membrane technology to reduce chlorine, TDS, chemicals, and other common contaminants.

Does this system require a drain connection?
Yes. All RO systems produce wastewater during filtration and require a drain saddle connection to operate properly.
