Premiere Ultrafiltration RV Water Filter System – Easily connects to your RV’s water entry point hose to filter all incoming water. Microscopic filtration (0.02 micron) removes harmful bacteria, sediment, chemicals and more.
The Premiere ultrafiltration RV water filter system (PS-PURUF-RV) attaches easily and directly to your RV’s water entry point hose to filter all the incoming water. It has a 0.02 micron ultrafiltration membrane that removes particulates and solids like harmful bacteria, viruses, protozoa, sediment, and colloidal materials on a microscopic level. Ultrafiltration operates smoothly at low pressure; no pump or electricity required. This system produces water on demand with an outstanding flow rate of up to 2 gallons per minute.
Innovative feature lets you easily backflush (clean) the UF membrane when it gets filled with contaminants…you can’t do this with other filters or membranes, they need to be replaced when clogged. Extra long membrane life up to 3 years. Maintains naturally occurring minerals for health and taste. Ultrafiltration is a great alternative for traditional RO systems – UF provides very fine filtration without the water waste that occurs with reverse osmosis.
What is ultrafiltration?
Ultrafiltration (UF) is a type of membrane filtration which removes particulates and solids on a microscopic level. A membrane barrier acts like a filter using slight pressure to separate particles like bacteria, viruses, germs, pollen, algae, and inorganic and organic molecules from the water. Ultrafiltration is ideal for drinking water filtration for well water or municipal water. Read more about the differences between ultrafiltration and reverse osmosis here.
Benefits of ultrafiltration:
Environmentally friendly technology – UF produces no wastewater and doesn’t need electricity
An ultrafiltration membrane lasts much longer than a conventional water filter (years versus months)
Operates smoothly at low water pressure
Premiere PS-PURUF-RV Ultrafiltration RV Water Filter System Features and Benefits:
Attaches easily to your RV’s water entry point to filter all the incoming water going to your freshwater tank. This means you have access to clean, safe water from every tap for cooking, washing dishes, bathing, drinking*, and more.
0.02 micron UF membrane – Filters out solids and particulates as small as 0.02 micron including: bacteria, protozoa, cysts, viruses, algae, dirt, mold, silt, colloidal silica, clay, iron, sand, lead particulate, and more.
Enjoy peace of mind that the PS-PURUF-RV contains a membrane that removes bacteria (over 99.9999%), viruses (over 99.99%), and giardia & cryptosporidium (over 99.95%) from the water. This system provides more than a 5-log reduction of bacteria, cysts, viruses, and turbidity. In other words, bacteria, cysts, viruses, and turbidity have been reduced 100,000-fold.
It also feature two high performance 0.50 submicron carbon filters that reduce volatile organic chemicals (VOCs), chlorine, chloramines, pharmaceuticals, pesticides, lead, trihalomethanes (THMs), methyl tertiary butyl ether (MTBE), and more. 2,000 gallon capacity.
Works well at low water pressure. No pump or electricity needed to make this system work.
Prevent backups in water lines. This system removes ultrafine sediment and impurities from the incoming water. Clogs can damage your RV’s pipes and connections so this system saves money, time, and the hassle of fixing repairs due to line blockages.
Solid, lead-free brass fittings – hose connections are 3/4″ hose swivel thread (HST) and 3/4″ hose male thread (HMT) (please note that these fittings are not currently shown in the product image)
Zero waste water during the purification process. A conventional reverse osmosis system may waste 3 – 25 gallons of water to produce one gallon of reverse osmosis water. This system is revolutionary in that is does not waste water in the production of purified water.
Preserves healthful minerals in drinking water. One downside of reverse osmosis is that they remove naturally occurring and healthful minerals- the PS-PURUF ultrafiltration system leaves these healthful minerals in the water.
Back flushing membrane ensures longer water membrane life. When a membrane undergoes a backward flush, its pores are flushed inside-out to purge it of contaminants. Innovative valve on the system lets you flush (clean) the membrane whenever it gets full of contaminants. You can tell when it’s time to flush the membrane because there will be a drop in water pressure. Simply turn the valve to flush the membrane (please note that a small amount of water will be discharged while the valve is open). Membrane should be replaced every 2-3 years.
Change the water filters quickly, easily, and less often. Our high capacity filters only need to be changed after 2,000 gallons or once per year (whichever comes first). Other filters have far less capacity and need to be changed the filters twice per year which is time-consuming and costly.
The ultrafiltration membrane should be flushed on a regular basis to ensure longest membrane life. To flush the membrane, simply turn the valve and leave open for up to 15 seconds to fully flush the membrane. A small amount of water will be expelled while the valve is open – it may be helpful to have a tub or bucket to capture this water.
How often you flush the membrane will depend on your water conditions and water usage. Flush the ultrafiltration membrane at least once per month; some users may find they need to flush it a few times a month, weekly, or even daily.
In general, you will know it is time to flush the membrane when there is a consistent, noticeable drop in water pressure. At minimum, it still should be flushed at least once per month even if you do not notice any drop in water pressure.
The ultrafiltration membrane (PS-PURUF-MEM) should be replaced once every 2-3 years, and the activated carbon block replacement water filters (PS-PURUF-RC) should be replaced once per year, or after 2,000 gallons (whichever comes first).

PS-PURUF-RV Installation Instructions
Premiere PS-PURUF-RV ultrafiltration RV water filter system replacement water filters (PS-PURUF-RC) are available here and the replacement membrane (PS-PURUF-MEM) is here.
Remember to replace your PS-PURUF water filters once a year, or after 2,000 gallons (whichever comes first), and replace the membrane once every 2-3 years.
This system attaches to your RV’s hose so will filter all the water that enters your RV, however please ensure your pipes, plumbing connections, valve, any hose after the system, and freshwater tank is clean / safe / sanitized for use. A point-of-use filter for drinking water is recommended.
This product is NOT recommended for water with a high TDS level (over 500 ppm) or if you wish to remove all TDS.The perfect amount of TDS in drinking water is 300 – 500 ppm, and ultrafiltration maintains that range by reducing harmful contaminants and preserving healthful minerals. If you have a TDS level above 500 ppm or wish to remove all TDS, please keep in mind that only reverse osmosis will remove virtually all TDS in water.
*We recommend a point-of-use filter for drinking water. Taste-wise, if you want to achieve “tasteless” water that is free from minerals (i.e., how some bottled water tastes – or doesn’t taste, rather) you will want to consider reverse osmosis because ultrafiltration preserves healthful minerals which can contribute to how your water will taste.
Do not install the PS-PURUF-RV after any water softeners that use sodium (salt). This is because some water softeners make hard water “soft” by replacing the calcium and magnesium with sodium. These high levels of sodium break down the membrane.
