Replacement RO Membrane 1812-50 GPD for Reverse Osmosis 29.8 x 4.8 cm Polymer Composite Filter for Kitchen Drinking Water Purifier
You already have the maximum available quantity in your cart.
The replacement membrane for reverse osmosis model 1812-50 is designed to replace the worn-out filter cartridge in domestic drinking water purifiers. The nominal capacity of 50 GPD corresponds to approximately 189 litres of treated water per day, which is a lower daily output suitable for smaller households. The membrane is the main component of the entire reverse osmosis system, and it is where the separation of pure water takes place. By regularly replacing the membrane, you will keep your kitchen purifier in good condition. The cartridge is installed into a standard membrane housing in the RO system.
The membrane is manufactured using polymer composite reverse osmosis technology, which, according to the manufacturer, ensures a high degree of desalination, rapid water production, and a low proportion of waste water. Inside, the filter material is wound around a central tube for pure water. At one end is the water inlet with a sealing ring, and at the other end is the outlet for the filtered water. The cylindrical body with a blue casing has a length of 298 mm and a diameter of 48 mm, which corresponds to standard membrane housings in domestic purifiers. The manufacturer states that the membrane is suitable for water purifiers of various brands and for treating water from municipal water 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 inlet water, daily consumption, and the condition of the pre-filters that protect the membrane from coarse impurities. Therefore, it is advisable to check the pre-filters in the purifier when replacing the membrane. The membrane is supplied separately without a housing and without additional filters, so it can be inserted into the existing system. When selecting, refer to the marking of the original membrane and the dimensions of the housing in your purifier.
