that looks like a BRS system. you can go on there website and order the proper stage(either 4,5,or 6) replacement filters for it. depending on how old the system is, you can also replace membrane. they don't need to be replaced as much. i am sure you can find the filters cheaper elsewhere if you look.
 
The BRS site should also have a video showing how to replace each part of the RODI system. If you're looking to get supplies local I go to AP for my RODI stuff.
 
Bulk reef supply sells a lot of the filters. It should have come with a filter wrench that fits around the canisters. You just shut the water off that supplies it. Release any pressure on the output side. Then the filters just twist off.

The actual filters inside are just drop in units. Pull one out. Put new one in. And screw the canisters back on. It is very simple when you go to do it.

If you're reading .001 after the DI stage, the resin needs to be replaced. What's the reading before it? If it's high, the DI will be consumed much faster meaning the RO membrane should be replaced.

Its a good idea to replace the sediment filter (very cheap) and carbon block if you can. The RO membranes last for a few years so you are probably OK there. You'll need DI resin too and yes BRS is the best place to get them

.001? Really? Isn't there a range of tolerance?
 
I thought TDS read in PPM. If that's right, your readings are sky high enough that I question the accuracy with what you tested them with.
 
I just replaced mine. It was super simple. Make sure you pack the di resin really well. There are tons of videos. If I were you I would buy the ro membrane and the filters just as a piece of mind. Like I said I just did all mine from brs cost maybe 70 bucks with the ro membrane
 
Don't forget to sanitize the unit at least once a year, and also to lube the housing orings every time you change the filters.

When you install new carbon blocks make sure you rinse them - and don't allow that rinse water to go into other filter stages.
