The utility model relates to the field of filtering devices, in particular to an RO (
Reverse Osmosis) membrane water filtering device which comprises a base, a water pump fixed at one end of the top of the base, a first water inlet
pipe fixedly communicated with the input end of the water pump, a first water conveying
pipe fixedly communicated with the output end of the water pump, and a front filtering
assembly fixedly communicated with the first water conveying
pipe, the RO membrane water filtering device has the beneficial effects that water can be pre-filtered firstly, so that the blockage degree of the RO membrane water filtering device is effectively reduced, the frequency of replacing the RO membrane can be effectively reduced, the water filtering period of the RO membrane can be prolonged, and when the RO membrane is replaced, the RO membrane can be conveniently replaced, so that the water filtering efficiency of the RO membrane water filtering device is improved. The water filtering efficiency of the RO membrane is greatly improved, and the water filtering device is suitable for being popularized and used.
