Replacement Membrane for Reverse Osmosis 1812-75 GPD 29.8 x 4.8 cm Polymer Composite RO Filter for Domestic Kitchen Water Purifier
You already have the maximum available quantity in your cart.
Model 1812-75 is a replacement membrane for reverse osmosis, designed to restore the function of your domestic drinking water purifier. With a rated performance of 75 GPD, it can handle approximately 284 litres of treated water per day, providing a medium daily output suitable for an average household. The membrane is the heart of the RO system, separating clean water from waste. By replacing an old cartridge with a new one, you can return your purifier to its original performance. It fits into a standard membrane housing.
The membrane is manufactured using polymer composite reverse osmosis technology, which the manufacturer claims ensures a high level of desalination, rapid water production, and a low waste water ratio. Inside, the filtering material is wound around a central tube for clean water. At one end is the water inlet with a sealing ring, and at the other, the outlet for filtered water. The cylindrical body with a blue casing measures 298 mm in length and 48 mm in diameter, which corresponds to standard membrane housings in domestic purifiers. The manufacturer states that the membrane is suitable for various brands of water purifiers and for treating water from municipal supplies.
Consider replacing the membrane especially when the flow of treated water decreases or its taste changes. The replacement interval depends on the quality of the input water, daily consumption, and the condition of pre-filters that protect the membrane from coarse impurities. Therefore, it is advisable to check the pre-filters in the purifier during replacement. The membrane is supplied separately without housing and without additional filters, allowing you to insert it into your existing system. When selecting, refer to the markings on the original membrane and the dimensions of the housing in your purifier.
