5.The membrane of other brands was installed before. Is this membrane universal?
Yes, the same model can be used.

6. How long is the service life of the membrane?
The service life of the membrane is not specific to determine the answer, the general service life is 1-2 years. It depends on the quality of raw water, the size of water consumption, the proportion of pure water and wastewater equipment, prefilter material and equipment operating pressure, which will affect the service life of RO membrane.

7. What is the difference between model 21 and model 31?
The capacity of model 21 is slightly larger, but the TDS is slightly higher. The capacity of the model 31 is not as large as that of the model 21, but the water quality is better.

8. What is the difference between ULP and LP?
ULP is low-pressure reverse osmosis membrane, the working pressure is 6-8 kg; LP is high-pressure reverse osmosis membrane, the working pressure is 15kg; when choosing, please know the required product model in detail.
