They must not last long. I'm still using the same DI on my unit for 14 months.

The main issue is that this system is proprietary. It isn't using industry
standard sized products, so you will have to buy replacement filters and the DI
cartridge from this vendor or any vendor that sells this setup.

The industry standard is 10" filters, which can be obtained anywhere. And
110gpd membranes aren't common either. 100gpd is.

Actually the only thing that isn't standard is the di filters, the
rest at least on the unit I got (not from this guy, but the one from
Canada that sells on ebay) are standard. And the DI filters are
cheaper even from them. $50 for 4.
