SimPure T1-400ALK Replacement Filter Cartridge Pack Set for T1-400ALK Tankless Reverse Osmosis Water Filter System (2 PP Filter+2 CTO Filters+1RO Filter+2 ALK Filters)

We use our RO all the time. The filters work great.

One set, the alk filter leaks. Since its not necessary, we skipped changing it on the 2nd round but the filters cost enough that they should work. The setup itself is great, just wish we didn't have leak issues.

Too much water waste. I kept this thing off for a week, and turned on yesterday, it doesn’t stop wasting water. 24x7 it runs and waste water. Here’s the proof how much water it is wasting each day !

great RO we bought filters to get them incase prices go up... Out Revese Osmosis filter makes us so happy.

I got this set and stashed it in a cabinet even though I'm convinced that the original set that came with the filters is going to last us longer than advertised based on our usage. Still, got to have them. Two of my previous filter systems had either gone out of business or stopped making replacement cartridges when I was shopping for them. I'm looking at a few years of supply here.
