Description
The TFC-75F AQUAFILTER 75 GPD Membrane is a high-performance osmotic membrane designed for domestic and aquarium RO systems. It is a key component used in reverse osmosis, as it is responsible for highly precise separation of clean water from contaminants discharged to the drain. It is a proven choice for applications such as an osmotic filter, a reverse osmosis system, and everyday water treatment at home.
The TFC-75F model offers a capacity of up to 75 GPD, i.e. up to 280 liters per day, 96-99% reduction of dissolved contaminants larger than 0.001 µm, and compatibility with standard, screw-off housings. This RO cartridge helps obtain water suitable for drinking, cooking, household use, and aquarium applications.

How the AQUAFILTER TFC-75F membrane works
The TFC-75F membrane has a multilayer structure. The individual layers are wound around a perforated core located inside the cartridge, creating an effective water and contaminant separation system.
During operation, contaminated water is forced under pressure onto the membrane surface. Water molecules pass through microscopic pores, while unwanted substances are retained. Rejected contaminants are directed to the drain, and purified water passes through the openings to the central core and then flows out of the membrane under pressure.
In practice, this means the effective performance expected from a modern RO cartridge for water filtration systems. The membrane retains 96-99% of dissolved organic and inorganic contaminants, heavy metals, and radioactive elements with a size of at least 0.001 µm.

Key benefits of use
- Capacity up to 75 GPD, i.e. up to 280 liters per day.
- Effective osmotic filtration and separation of clean water from contaminants removed to the drain.
- 96-99% reduction of dissolved contaminants larger than 0.001 µm.
- Compatibility with standard, screw-off housings for domestic and aquarium RO filters.
- Average service life of approx. 5-6 years with proper use.
- Operating pressure 2.2-8 atm.
- Chlorine tolerance: 0 ppm.
A 75 GPD capacity is one of the most commonly chosen standards in reverse osmosis systems. Such throughput provides an amount of clean water sufficient for a typical household, which is why 75 GPD membranes are widely used in domestic RO sets.
What the water after osmotic filtration can be used for
Water obtained thanks to the operation of the TFC-75F membrane has a wide range of uses at home and beyond. The user description of this model indicates the following areas of application:
- recommended for drinking for people prone to kidney and gallbladder stones,
- excellent for caring for delicate baby skin, washing the face and teeth,
- does not leave limescale residue in kettles, irons, coffee machines and similar appliances,
- recommended for making ice cubes for drinks,
- excellent for washing fruit, vegetables and meat,
- can be used for aquarium applications and watering plants,
- can be used as a source of clean water for pets.

Compatibility and use in RO systems
The AQUAFILTER TFC-75F membrane fits all standard, screw-off housings for osmotic filters used in domestic conditions and aquarium installations. This means it can be used as a replacement cartridge in many popular RO systems.
It is an important component when you want to maintain the high efficiency offered by a reverse osmosis filter. Replacing a worn-out membrane with a model of the appropriate capacity helps maintain the proper operation of the entire water filtration system.
The membrane has a chlorine tolerance of 0 ppm, so in a reverse osmosis system it should operate behind properly selected prefilter cartridges. Proper operation and regular prefilter servicing help maintain filtration efficiency and the membrane’s average service life at approx. 5-6 years.

Questions
Which systems does the AQUAFILTER TFC-75F membrane fit?
The TFC-75F model fits standard, screw-off housings of domestic and aquarium reverse osmosis filters. It is designed to work as a membrane cartridge in typical RO systems.
What does 75 GPD capacity mean?
75 GPD means a capacity of up to 75 gallons per day, which for this model corresponds to a maximum of about 280 liters of water per day. It is a popular standard suitable for a typical household.
What contaminants does the TFC-75F osmotic membrane remove?
The membrane retains 96-99% of dissolved organic and inorganic contaminants, heavy metals, and radioactive elements with a size of at least 0.001 µm. The contaminants are separated from the clean water and discharged to the drain.
Is this membrane suitable for a home water filter?
Yes, it is designed for domestic reverse osmosis systems and works well as a key component of an RO installation used for everyday water treatment.
How long can the TFC-75F membrane be used?
The average service life of the membrane is approximately 5-6 years. The actual operating time depends on the quality of the feed water, operating pressure, and the condition of the prefilter cartridges protecting the membrane.
Why is 0 ppm chlorine tolerance important?
This means the membrane is not intended to come into contact with chlorine. Therefore, the RO system should use properly functioning prefilter cartridges that remove chlorine before the water reaches the membrane.
What can the water after osmotic filtration be used for?
Such water is suitable for drinking, caring for delicate baby skin, washing the face and teeth, preparing ice cubes, washing fruit, vegetables and meat, aquarium use, watering plants, and as clean water for pets. In addition, it does not leave limescale residue in many household appliances.
Does the TFC-75F membrane leave scale in a kettle or coffee machine?
Water after osmotic filtration does not leave limescale residue in kettles, irons, coffee machines and similar appliances, which is one of the practical benefits of everyday use of an RO system.
