Home & Business Reverse Osmosis Membrane Replacements


At wateranywhere, we pride ourselves on our ability to serve any water filtration needs from home water purification to a variety of commercial applications including hotels and resorts, petrochemical, and food and beverage production.


Designed for point of use (POU) installation under the sink or counter, these RO filtration systems supply clean drinking water directly to a faucet, spigot, or refrigerator. We offer Applied Membranes, LG, Filmtec, and GE residential RO replacement membranes that fit a variety of reverse osmosis filtration systems. Consult this chart for a listing of applicable membrane sizes for various models.

Whole House RO Membrane Replacements


These systems are designed for point of entry (POE) installation to provide water free from contaminants to the entire building. This system connects to the main water line. We offer whole house RO membrane replacements from a variety of brand names.

Commercial RO Membranes


Replacement RO membranes used in a variety of business applications are typically run at higher pressures for optimum performance and higher rejection. We offer replacement membrane elements for water treatment systems used for water stores, larger facilities, carwashes, and manufacturing.

Reverse Osmosis Seawater Desalination


Seawater desalination forces seawater through a semipermeable membrane removing most of the impurities. This technology is used in several markets from oil and gas, to specialty applications. wateranywhere supplies RO replacement membranes used in seawater desalination used for converting seawater into usable, drinkable water.

MF, UF, NF, and RO Membranes Separation Processes Explained


Membrane elements are used in the membrane separation technology processes; all of which serve different levels of demineralization and decontamination. The different processes of separation refer to the pore size and type of semi-permeable membranes used to remove organic matter from the water. Microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes are explained below:

Microfiltration Membrane Separation


(pores equal 0.1 micron)- A pressure-driven filtration process which removes many microorganisms and suspended solid materials but allows smaller ions, particles, and many viruses to pass through.

Learn More

Ultrafiltration Membrane Separation


(pores equal to 0.01 micron)- UF is a pressure-driven separation process which removes larger microorganisms and suspended particulate matter as well as bacterias and most viruses. However, cannot remove dissolved substances without first absorbing them using a coagulate.

Learn More

Nanofiltration Membrane Separation


(pores equal 0.001 micron)- This type of filtration membrane blocks even smaller organic molecules and almost all viruses, as well as most organic matter and salts. NF is often used to soften hard water because it can remove divalent ions, which cause hard water.

Learn More

Reverse Osmosis (RO) Membrane Separation


(0.0001 micron)- RO is one of the most extensive and efficient water filtration methods. A RO system uses a pump to force water through the membrane. Contaminants remain on one side of the membrane (wastewater later drained) resulting in pure water collection on the other. Reverse osmosis removes 98% of harmful minerals including fluoride, salts, sediment, arsenic, chlorine, VOCs, herbicides, pesticides, bacteria and viruses.

Replacement Membranes & Components for Reliable Water Treatment


At wateranywhere, we know how vital clean, quality water is, which is why we take pride in offering the best in breed water filtration systems and RO replacement membranes. We offer reliable service and flexibility to best meet our customers’ needs including quick shipping, and affordable installation. We offer same day shipping on orders received before 3 PM PST.
