I have moved into a "new to me" house recently that has a RO system installed. I dont know much about the system. The mount says
Performance Water Products, but an email to them has gone unreturned.

I took apart the system and the Membrane is a GE Osmonics TFM-36, so I will replace that.

However below the membrane canister are 3 vertical canisters. 2 carbon and 1 sediment filter. After opening those housings the filters themselves dont have any identifying information. They are 9.75 X 2 7/8.

How do I determine which micron rating carbon block filters to purchase? 1micron, 5micron, etc?

Thanks for your help.

The sediment filter is first in line. A 5-micron may be used. Then comes a carbon filter which is probably a GAC filter, then the water goes to the membrane and tank before going into the carbon block filter.

The carbon block filters are typically 5 microns as well.

Check the air pressure without water; it should be 7-9psi.
