Great Products with Attentive Service

I get a lot of use out of this filter. Couldn't install an under-the-sink RO unit at my apartment, but the OnliPure filter is well worth the cash and counterspace. Bought a TDS tester out of curiosity, and its reads 0ppm when I tested water from it.

The filter replacement is going much smoother than at first. Itโ€™s easier to to detach. As always the water quality and taste is outstanding.
